In today’s fast-paced world, people often make career or life choices based on pressure, myths, or limited exposure. This leads to regrets later in life, which remain hidden and unspoken. Students, especially in undergrad years, rarely get to learn from these real-life regrets, and society keeps repeating the same mistakes.

Solution:
The Second Chance Book is a digital space where individuals can anonymously share their regrets and the lessons they learned. Instead of advice coming from the top down, this creates a collective “library of lived experiences.” Students can explore paths others wish they had taken, and myths — like “engineering and medicine are the only worthy fields” — naturally get broken when real people’s stories are visible.

Who Benefits:

• Students: They gain clarity and perspective before making big life decisions.
  

• Educators and Parents: They see patterns in regrets, helping them guide better.

• Society at large: By surfacing hidden wisdom, we reduce the cycle of repeated mistakes.

Why It Matters:
Every regret is a missed opportunity for learning. By turning them into shared lessons, we make invisible struggles visible. This empowers students to make informed, less fear-driven choices and builds empathy across generations. It’s not about fixing the past, but about shaping a better future.

Innovative Feature:
The uniqueness lies in its framing. Unlike motivational blogs or career advice forums, The Second Chance Book is built entirely on real, anonymous regrets. With a light AI touch, it can highlight recurring themes (e.g., “70% of contributors wished they explored creative fields”) and showcase myths that need breaking. This makes it not just a platform of stories, but a mirror of collective human wisdom.

Conclusion:
The Second Chance Book is more than a collection of regrets — it’s a way of passing on hard-earned life lessons. By giving a voice to what often goes unspoken, it helps the next generation make choices with courage, clarity, and awareness.

1. Problem:

Most people don’t realize how much their daily activities, like traveling, eating, or using electricity, contribute to pollution. Without this awareness, it’s hard to make eco-friendly choices, which adds to climate change.

2. Gap in Current Solutions:

Some apps exist to track carbon emissions, but they are often too complicated, require too much manual input, or focus on large industries rather than individuals. People need something simple and easy to use every day.

3. Big Idea :

A Carbon Footprint Tracker App that records your daily activities and shows how much carbon they produce. The app helps you understand your impact and suggests simple ways to reduce it.

4. How It’s Different

• Very easy to use with minimal input.

• Tracks different areas: travel, food, and energy use.

• Gives personal suggestions to lower your carbon footprint.

• Shows progress with clear visuals over time.

5. Main Features

• Log daily activities like commuting, meals, and electricity use.

• Get a clear calculation of the carbon impact for each activity.

• Receive tips to make small changes that reduce pollution.

• View weekly and monthly progress in charts and graphs.

• Option to compare with friends or local averages for motivation.

6. Who Benefits

• Individuals → understand and improve daily habits.

• Communities → collective reduction in pollution.

• Schools/colleges → use for awareness campaigns.

7. Impact

By showing daily effects and suggesting easy changes, the app encourages eco-friendly behavior. Small actions by many people can lead to a significant positive impact on the environment.

Problem Statement: In today’s fast-paced lifestyle, people often forget to stay hydrated, leading to health issues such as fatigue, headaches, and decreased concentration. Existing fitness apps track hydration manually, but they rely on user input, which is often inaccurate and inconvenient.

Gap in Current Solutions: While there are apps and smartwatches that remind people to drink water, very few solutions provide real-time tracking of actual water intake. Moreover, most “smart bottles” available are expensive and not widely accessible for students or the general public.

Proposed Idea: My idea is to create an affordable Smart Water Bottle with built-in sensors that measure the exact quantity of water consumed throughout the day. The bottle will connect via Bluetooth to a mobile app that:

• Tracks hydration in real-time.

• Sends reminders if the daily water goal is not met.

• Provides personalized recommendations based on climate, body weight, and activity level. Additionally, the bottle will have a small solar-powered strip for self-charging, making it energy-efficient and eco-friendly.

Beneficiaries: This idea benefits students, office-goers, athletes, and even elderly people who often forget to hydrate. It also encourages sustainability by reducing the use of disposable plastic bottles.

Why It Matters to Me: I have personally experienced dehydration during long classes and sports activities. This motivated me to think about a practical, affordable, and sustainable solution that not only improves health but also promotes eco-conscious living.

Problem Statement

Free trials auto renews to paid plans(e.g., ₹200/₹800 per month) unless you cancel, prices increases quietly, and we lose track of who’s charging what. “Subscription creep” drains student budgets because renewals are designed to be forgettable, especially tricks like “annual plan, billed monthly.”

Gaps Today

• We forget: notes/spreadsheets go stale and reminders don’t work.

• Emails/SMS get buried: real renewal alerts hide in the noise.

• Cancelling becomes harder: confusing menus and sometimes a fee.

• Small printing tricks: “annual, paid monthly” isn’t obvious at signup.

• Family plans waste money: charging for family plans without using its full services.

Solution

SubTrack is a mobile app with an optional browser extension that allows the user to:

• Auto-detect recurring charges from bank SMS/email.

• Show a single dashboard with next billing dates, monthly spend, and price-hike alerts.

• Start a trial/renewal timer at signup and sends a notice to you 48/24/3 hours before charging.

• Offer one-tap cancel/keep: deep links to the exact cancellation page + a pause card shortcut for stubborn services.

• Flag annual-billed-monthly commitments and shows the real cancel cost vs cost to keep it for 1 more month.

• Shows shareable plans and unused seats among friends/family to cut costs.

Who Benefits?

it benefits Students, clubs, and even families juggling OTT, music, cloud, course sites, design tools, and other streaming services such as Netflix.

why this problem matters to me?

I had recently purchased a free trial from a adobe service for a project, i had unknowingly accepted the terms and conditions. After the project i had forgotten about the free trial and lost thousands and even after attempting to cancel they had requested additional fees, so to prevent such mishaps SubtTrack allows individuals to control their data without handing it to yet another cloud service.

Solving a real-world problem

• Each morning, I waste time gazing at my closet, wondering what to wear.

• At times, I'm just too lazy to exert effort in styling, and other times I judge myself by my appearance.

• Selecting an outfit shouldn't exhaust energy before the day starts.

• That's why I came across ClosetMate, the app that functions as your own personal stylist: it identifies your existing clothes and pairs them into chic outfits that correspond to the weather, event, and your mood.

Why?

• Decision fatigue: Research indicates we make dozens of tiny decisions every day, and "what to wear" is one of the most frequent morning drains.

• Time wasted: Individuals spend 10–20 minutes a day selecting outfits → that is hours a month.

• Confidence & judgment: What we wear is closely linked with first impressions and how others see us (and how we see ourselves).

• Overconsumption: People continue purchasing new garments because they think they "have nothing to wear," even if their closet is already filled.

How the app works

• Upload Your Wardrobe: Take photos of your clothes. AI automatically identifies type, color, fabric, and season.

• Daily Outfit Recommendations: ClosetMate suggests 2–3 outfits you can wear each morning, taking into account:

  • Today’s weather

  • Your occasion (work, casual, date, festive, etc.)

  • Your mood/comfort (formal, relaxed, cozy, trendy)

  • Current fashion trends

• Personalization Options:

  • Mark your favorite outfits so they can repeat themselves.

  • Apply restrictions (e.g., "no jeans today").

  • Receive smart alerts like "pairing this shirt with neutral sneakers gives 5 new looks."

• Optional Add-ons:

  • Weekly planner: Plan outfits for the whole week.

  • Smart suggestions: Offer items you can purchase that open up more outfit possibilities.

  • Record how often you've worn each item (promoting sustainable fashion).

ClosetMate is there to help you look great without that morning hassle. It keeps you efficient, self-assured, and stylish all at once.

Lapses in existing solutions

• Most fashion apps now specialize in just shopping, not assisting in styling what you already have.

• Closet management apps do exist, but they're too complex or fail to account for personal issues such as mood, comfort, or weather.

• ClosetMate plugs the gap with an uncomplicated, day-to-day styling companion that makes fashion easy.

Who benefits

• Target Users: Normal people like me who don't want to spend energy on styling but still wish to look good. Working professionals, students, and anyone who has a "what to wear" problem every day.

• Buyers (brands/retailers): Fashion brands can sell products that actually fill users' wardrobe gaps, rather than being forced to show generic ads.

• Community: Encourages sustainable fashion by making users reuse and restyle their clothes instead of buying new ones every time.

Why this issue is important to me

• I'm too lazy to search for a dress first thing in the morning, and I don't want to spend mental energy each day thinking about outfits.

• In addition, sometimes I feel judged by others according to how I appear.

• ClosetMate eliminates both issues—it makes me more efficient without losing style and confidence.

Access to essential medicines in urgent situations is a problem many people face daily. While quick-commerce apps like Blinkit and Zepto promise ultra-fast delivery, their focus is primarily on groceries and only a limited set of general medicines. On the other hand, dedicated pharmacy apps like NetMeds and Apollo often take several hours or even a full day to deliver. This gap leaves users stranded when they need medicines immediately—for emergencies, chronic care needs, or sudden health issues.

PharmInsta is designed to solve this problem by creating the sirst true instant pharmacy delivery platform, ensuring essential medicines reach customers within 10 minutes. By leveraging a demand-driven supply chain model, PharmInsta strategically places micro-fulfillment centers across urban areas and partners with local pharmacies to keep inventory close to where it is needed. Predictive analytics will track regional demand to ensure the most critical medicines—such as fever reducers, antibiotics (with prescription), inhalers, and emergency medical supplies—are always stocked nearby.

The primary beneficiaries of this service are everyday users: students living alone especially in hostel, working professionals, families, and especially patients with chronic conditions who cannot afford delays. PharmInsta also empowers local pharmacies by extending their reach through technology, helping them serve customers faster without being limited to walk-ins. On a community level, this service creates a safety net—because timely access to medicines can literally save lives.

This problem matters to me personally because I have experienced the frustration of not being able to get urgent medicines when my best friend needed them. No app—whether NetMeds, Apollo, or quick-delivery services—could provide the right medicine within minutes. PharmInsta was born from that moment, with a vision to make sure no one feels helpless when timely medicine could make all the difference.

Problem Statement:
India’s agriculture sector loses 15–20% of produce post-harvest due to poor logistics, fragmented supply chains, and lack of access to reliable transport and storage. Smallholder farmers often walk long distances to sell crops, wasting time and labour. During harvest peaks, markets face sudden gluts, leading to distress sales and poor price realization.
The problem is worse in remote or semi-urban regions where:
• Trucks are unavailable or unaffordable for individual farmers.
• Storage infrastructure is insufficient.
• Farmers cannot access urban markets directly, losing bargaining power.
This leads to high spoilage, low income, and price volatility, affecting both farmers and buyers.

My Solution:
I propose AgriDirect – a hybrid farm-to-market procurement and logistics platform designed to make agriculture supply chains smarter, faster, and more profitable for everyone involved.
Doorstep Procurement & Scheduling: Farmers can schedule pickups through a mobile app, call center, or local agent. Group pickups are encouraged to reduce per-farmer transport costs, improving collective bargaining power.
Smart Fleet Management: Instead of purchasing vehicles, we rent trucks in bulk during harvest seasons for lower capital requirements and better cost efficiency. Trucks are dispatched to multiple villages on optimized routes, allowing for maximum utilization and quick turnaround.
Hybrid Warehousing: During harvest peaks, we pre-book large warehouse space at negotiated bulk rates to ensure sufficient capacity. For longer-term storage, we operate owned warehouses with temperature and humidity control to preserve grain quality until market prices improve.
Year-Round Operations: To keep the network active beyond harvest season, we deploy smaller vans/tempos that collect eggs, milk, and vegetables daily or weekly. These are sold to urban markets, restaurants, and retailers, ensuring steady cash flow for farmers and continuous revenue for the business.
Digital Ecosystem: A user-friendly dashboard provides farmers with real-time updates on collection schedules, pricing trends, and payments, while buyers and wholesalers can track available inventory.

Value Proposition:
Existing agri-supply chains are fragmented, expensive, and seasonal. Most solutions focus only on harvest logistics and ignore continuous income streams for farmers. AgriDirect’s hybrid approach keeps costs low (by renting assets seasonally) while maximizing farmer value through:
• Reduced transport cost and time
• Reduced spoilage and post-harvest loss
• Collective bargaining power through group pickups
• Consistent cash flow via dairy/vegetable collection
• Better price realization through smart warehousing & timing of sales
This creates a sustainable, scalable, and tech-enabled agri-logistics solution that benefits both farmers and buyers.

Who Benefits:
Farmers: Save time by avoiding long trips to mandis, reduce spoilage losses, gain collective bargaining power through group pickups, and receive timely payments. The addition of year-round collection for milk, eggs, and vegetables ensures consistent cash flow instead of relying solely on harvest income.
Buyers and Retailers: Gain access to reliable, pre-aggregated, high-quality produce with consistent supply throughout the year. This improves their planning, reduces procurement costs, and stabilizes pricing for end consumers.
Local Communities: Benefit from improved rural economy, reduced food wastage, and better price transparency, ultimately increasing income security and economic resilience.
The Business: Gains steady year-round operations, high fleet utilization, and multiple revenue streams, making it financially sustainable and scalable across districts.

Why This Matters to Me:
Coming from a background where I have seen farmers face challenges with transportation and price realization, I believe logistics should not be the bottleneck that reduces their hard-earned income. Agriculture is the backbone of rural India, yet farmers still lose money due to inefficiencies that can be solved with better planning and technology.
AgriDirect would be an attempt to bridge this gap — by building a platform that provides fair pricing, optimizes transport and warehousing, and ensures continuous engagement with farmers even outside harvest seasons. This is not just a business model, but a way to uplift farming communities while running a sustainable, scalable enterprise.

Modernizing train boarding by allowing train doors to open only after ticket verification addresses several ongoing issues. Currently, many passengers board without valid tickets because platform checks are inconsistent, and manual inspections can't keep up in crowded stations. By moving the verification to the train doors, a door will physically unlock only after the traveller’s ticket is scanned and validated. This creates a reliable enforcement point that works better than platform patrols.

This approach fills a gap between metro systems with gates and long-distance railways. Metros control entry at fixed points, while intercity trains typically allow free boarding along long platforms. Door-level verification enables control at each coach door, preventing ticketless boarding even in crowded stations. It reduces revenue loss, lowers congestion inside coaches, and improves safety and comfort for passengers.

Who benefits?
• Passengers benefit from fewer overcrowded coaches, fairer access, faster boarding, and increased safety.
• Rail operators gain from reduced fare evasion, more accurate passenger counts for scheduling, and lower inspection costs.
• Communities and law enforcement see better crowd control, along with fewer conflicts and incidents.

Why it matters to me: trains are vital public infrastructure. Ensuring safe, fair, and efficient rail travel has a significant social and economic impact. It protects revenue and improves the daily journeys of millions. It also reduces the risk of thefts, harassment, and other security issues inside coaches. 

Technical details: add a secure access-control module to each coach door, which includes a QR, NFC, or smart card reader and a short-range scanner. These readers will validate tickets in real time against the central reservation and ticketing database, with cached options for offline situations. A door will only unlock if the ticket is valid for that coach, train, and time. Safety features include emergency manual override, accessibility modes, audio and visual prompts, and conductor override for special cases. Privacy and fraud controls, such as session tokens and anti-replay measures, ensure secure operation.

Traditional education is limited by geography, resources, and the lack of immersive experiences. While video conferencing tools like Zoom or Google Meet allow students to connect virtually, they are still flat, passive experiences that cannot replicate the sense of presence or hands-on engagement. Field trips, labs, and cultural exchanges are expensive and often inaccessible, leaving a major gap in how students learn and collaborate globally.

My idea is to create Virtual Reality (VR) Classrooms—a platform where students and teachers from around the world can meet in shared 3D spaces to learn, explore, and collaborate. Imagine walking through ancient Rome during a history lesson, conducting a chemistry experiment in a virtual lab, or teaming up with peers from another country to solve real-world problems in a VR environment. Unlike standard online classes, this solution provides immersive, interactive, and collaborative learning experiences that make lessons more engaging and memorable.

The key beneficiaries are students, who gain deeper understanding and global exposure; teachers, who get powerful new teaching tools; and schools/communities, which can provide opportunities that would otherwise be limited by cost or location. For example, a rural school without a science lab could still give students hands-on experiments through VR.

This problem matters to me because education should not be restricted by borders or budgets. Technology should open doors, not close them. By enabling VR classrooms, we can create a world where students everywhere can learn beyond textbooks, build cross-cultural friendships, and prepare for a global future.

On the technical side, the platform could use affordable VR headsets, cloud-based hosting for shared spaces, and AI-driven translation tools to break down language barriers—making global collaboration truly accessible.

EQUILEARN HUB

Urban Rooftop Farming Network

In today’s cities, the cost of food keeps rising, supply chains are often unreliable, and pollution continues to worsen. Yet, if you look around, you’ll notice one thing in common—thousands of rooftops sitting idle. The idea behind the Urban Rooftop Farming Network is simple but powerful: turn those unused rooftops into thriving gardens and connect growers, buyers, and suppliers through a single digital platform.

The Problem: Right now, most households depend on food that travels hundreds of kilometers before reaching their plates. This makes it more expensive, less nutritious, and bad for the environment. Some people are experimenting with rooftop gardens, but these efforts are scattered and rarely supported with the right tools or a clear system.

The Gap: There isn’t a proper network that brings all these pieces together—urban farmers, kit suppliers, local buyers, and delivery options. People who want to farm often don’t know where to start, and those who succeed struggle to sell their extra produce.

Who Benefits:

• Residents enjoy fresher, healthier, pesticide-free food grown right in their neighborhood.
• The environment benefits from lower carbon emissions and more greenery to fight heat and pollution.
• Local businesses—from seed sellers to hydroponic kit makers—gain new opportunities.
• Communities strengthen as neighbors connect over farming and share harvests.

Why It Matters: Cities are growing, but food security is becoming harder to guarantee. At the same time, rising temperatures and air pollution are threatening urban health. Rooftop farming tackles both problems—providing fresh produce while cooling and greening the city.

How It Works: Affordable hydroponic kits, easy-to-use sensors, and a simple app make farming possible for anyone. The app also connects growers to neighbors and restaurants, while AI gives tips on how to improve yields. In short, it makes rooftop farming practical, profitable, and community-driven.

Adulting 101 – "Simplifying adulting, step by step."

Problem:
Students, and particularly those who are entering adulthood, struggle with fundamental but confusing activities: personal money management, career preparation, and dealing with documents such as IDs, banking, and visa papers. Local students struggle with procedures such as PAN or Aadhaar applications, while international students frequently arrive in a foreign country ignorant of how to set up a bank account, enroll in health insurance, or get a SIM card. These activities are essential for survival, yet the majority of students possess no reliable, beginner-friendly guidance.

Gap in Existing Solutions
Current tools are disconnected. Budgeting apps focus only on finance and overwhelm beginners with advanced features. Career sites such as LinkedIn or resume-building websites do not cover basic administrative work. Government websites offer required information, but it is dispersed, technical, and not student-centered. International student resources are restricted to universities or divided across unofficial blogs. No one, easy platform brings together finance, career, and paperwork advice for students.

What This App Does:
Adulting 101 guides students through essential life tasks by combining finance, career, and paperwork support in one platform. It tracks multi-currency budgets and sends reminders for rent, tuition, and bills. It provides a resume and CV builder with region-specific templates and interview prep tips. Paperwork guidance includes step-by-step checklists for IDs, visas, banking, SIM cards, and health insurance, with links to official portals and deadlines. The app also features a secure digital vault to store passports, IDs, bank documents, and certificates, with reminders for renewals, ensuring students have everything they need safely in one place.

Who Benefits:
Students (local & international): Local students receive step-by-step assistance for IDs, bank accounts, and bills, whereas international students are provided with country-specific checklists for visas, banking, SIMs, and insurance.
Parents & Universities: Peace of mind that students can take care of basic things on their own.

Solution / Features:
Adulting 101 combines three pillars:

Finance Basics: Multi-currency budget tracker with reminders.

Career: Resume/CV builder with region-specific templates and interview preparation.

Paperwork: Step-by-step guides for essential documents, with links to official portals and timelines for deadlines.

Smart Vault: A safe place to keep passports, IDs, visas, bank documents, and certificates with reminders for renewals or expiry. This way, students will have all essential documents readily available at all times.

Why It Matters:
I’ve seen my friends and people I know struggle with basic yet essential tasks, from paying rent to applying for a PAN card. International friends face even bigger barriers. This inspired the creation of a student-first tool that simplifies adulting.

 Gluco Vision – Non-Invasive Glucose Estimation Through Video

1. THE DREAM: Accessible Health for Everyone

One of the major growing diseases in the world,especially in India is Diabetes.Thousands and Millions of people live with diabetes or are at risk, but regular monitoring remains a challenge. The most traditional methods require finger-prick tests, which are painful, inconvenient, and costly.

For poor people who can afford the bare minimum, the financial burden is significant: a glucometer can cost between ₹800 and ₹1500, and test strips cost  between ₹15 and ₹30 each. This can reach between ₹1,000 and ₹2,500 per month for patients needing multiple daily tests. Due to the cost,most low income people frequently skip testing,which then increases the health complications such as heart diseases etc. which can even lead to death.

tThe idea with Gluco Vision is to make glucose monitoring affordable for everyone: a solution that is non-invasive, low-cost, and widely accessible, requiring only a smartphone or laptop camera.

2. The Problem: Painful, Expensiv

e, and Fragmented Monitoring

There are many problems created due to the traditional glucose monitoring:

• Invasiveness: Frequent pricking is painful and discourages adherence.
  
  
• High Cost: particularly for low income and poor people,continuous use of strips is expensive,
  
  
• Limited Insight: Finger prick tests only provide a snap
  shot of glucose levels,which are missing fluctuations throughout the day.
  
  
• Stress and Anxiety: it can lead to decrease of quality of life due to daily monitoring diseases

These limitations contribute to poor disease management, leading to hospitalization and diseases which can be avoidable.This mainly affects the poor.

3. Our Solution: Gluco Vision

Gluco Vision uses the power of photoplethysmography (PPG) which are video based  and machine learning to estimate blood glucose non-invasively, using just a camera and a smartphone.

Key Technical Highlights:

• • PPG Signal Extraction: Captures subtle color changes in fingertips from video, corresponding to blood volume changes.
    

• Signal Processing: to reduce noise from motion or lighting we apply Butterworth bandpass filtering and Savitzky-Golay smoothing
  
  
• Feature Engineering: To relate PPG signals with glucose dynamics,it computes heart rate, entropy, signal area, and other physiological features
  
  
• Data Augmentation: Generates synthetic glucose data to enhance training, combining real and simulated data for a better result .
  
  
• Machine Learning Model:To predict glucose levels with associated risk categories (normal, elevated, high),we Use Gradient Boosting Regressor 

Example Output:

 Model trained with enhanced real and synthetic data. Test MSE: 92.7
  Estimated Glucose: 142.3 mg/dL  Elevated glucose – Monitor or consult physician

Gluco Vision significantly reduces costs and makes regular monitoring feasible for low-income patients because we are eliminating the need for physical test strips.

4. Socio-Economic Impact

• • Budget friendly Healthcare: Eliminates the recurring expenses of strips and lancets.
    
    
  • Improved Compliance: encourages regular checks due to non-invasive monitoring.
    
    
  • Early Detection:reduces complications. Continuous or frequent monitoring which  allows for early intervention
    
    

• Accessible Anywhere: makes it feasible in remote or underserved areas as only a camera and internet-enabled device are required,
  
  

5. Future Roadmap

• Face and Fingertip Tracking: For easier, automated signal capture.
  
  
• Multiple Video Formats Support: Ensures compatibility across devices.
  
  
• Integration with Real-World Datasets: For better accuracy and better results we use real world datasets
  
  
• Advanced AI Models:  To improve predictive performance and accuracy we use Neural networks and deep learning
• Continuous Monitoring Potential: Enable long-term trends for proactive healthcare.

The Problem:
For many elderly people, hospitals feel like a maze. The noise, long queues, multiple counters, and endless departments can be overwhelming. On top of this, weak eyesight or poor hearing makes it even harder for them to read signs or follow announcements. What should be a place of care often becomes a place of fear. This confusion leaves many elderly patients panicked, anxious, and unsure of where to go.

The gap in the market:
Hospitals do have help desks, but they are usually crowded, and staff cannot give personal attention to everyone. Some big hospitals use digital counters or self-service machines, but most elderly patients are uncomfortable using them. And not every senior has a family member who can accompany them during their visit. These gaps show that there is no system truly designed with the elderly in mind.

The solution:
The proposed CareCompanion system would provide patients with a wristband or token at entry. Scanning it would give step-by-step audio guidance in their language to the volunteers, who would then escort them, while families track their movement through an app. Waiting areas with seating and water would add to their comfort.

Who does it benefit?
An elder-friendly guidance system would make hospital visits calmer and safer for senior citizens. Families would feel reassured knowing their loved ones are not lost or confused. Hospitals would see smoother patient flow and fewer repeated questions. Volunteers or interns who assist the elderly would also gain valuable experience and satisfaction.

Why it matters to me?
This issue is personal to me. My own grandpa once panicked and was almost lost in a hospital when he went alone. Seeing him so scared made me realize that elders deserve more than treatment—they deserve dignity, comfort, and guidance.

Technical details:
The Carecompanion system uses a smart wristband with BLE technology to guide patients. A network of hospital beacons and a central server provide real-time location and audio directions. It connects to secure apps for family tracking and volunteer alerts, ensuring a dignified and safe journey through the hospital.

One of the biggest problems in cities today is inefficient waste management. Overflowing garbage bins, uncollected trash, and littered streets are common scenes that affect not just cleanliness but also public health and the environment. Despite multiple efforts from municipalities, the systems in place often fail to handle waste efficiently. I thought—what if there was a way to use technology to manage waste more intelligently, ensuring that bins are cleaned before they overflow and resources are used optimally? That’s how the idea of “Smart Waste Management System” came to me.

The idea is to equip waste bins with sensors that measure how full they are in real time. These sensors would send data to a central system that maps all bins in the city. Garbage collection trucks would then be directed only to the bins that need emptying, avoiding unnecessary trips and reducing fuel consumption. The system could also predict peak waste times in different areas, helping the authorities deploy staff more efficiently.

The gap in current solutions is that most cities rely on fixed schedules, which lead to inefficiencies. Bins are emptied when they are not full, wasting time and resources, while some areas remain unclean because bins overflow before the next scheduled collection.

The beneficiaries are many:

• Residents, because streets will be cleaner and healthier.

• Municipalities, which can save money and reduce pollution by optimizing routes.

• Businesses and tourists, who will benefit from a cleaner environment.

• The planet, as better waste management reduces landfill overflow and harmful emissions.

This problem matters to me because I live in an urban environment where waste is a constant challenge. Seeing garbage piling up not only looks unpleasant but also leads to diseases and discomfort. Efficient waste management improves quality of life and reflects responsible governance.

From a technical perspective, the system could use low-cost IoT sensors, cloud-based analytics, and route optimization algorithms powered by machine learning. Data privacy can be ensured by only tracking bins and collection schedules without personal information.

Though there will be challenges like sensor maintenance, connectivity, and funding, the long-term benefits far outweigh the initial investment. By making waste management smarter, cities can become healthier, safer, and more sustainable for everyone. This is not just about garbage—it’s about dignity, health, and responsible living.

Problem it Solves: Students at universities spend a significant amount of money and time on daily commuting. Many take separate autos or cabs even if they’re traveling in the same direction. This not only raises costs but also increases wait times, adds to traffic congestion, and poses safety concerns for students commuting late or alone.

Current Market Gap: Popular ride-hailing apps like Ola or Uber are not designed for short, repetitive, hyperlocal commutes between campus and nearby neighborhoods. They are often too expensive for students, unreliable during peak class timings, and don’t leverage the trust factor of traveling with known peers. What’s missing is a low-cost, campus-centered mobility solution that’s safe, simple, and community-driven.

My Solution: A Campus Ride-Sharing App that matches students traveling along the same route. Features include:

• Smart Matching: Students heading in the same direction get grouped to share autos, cabs, or even bike rides.

• Cost Splitting: Fares are automatically divided among riders, saving up to 50–70% of commute costs.

• Safety First: Only verified students from the same university can join, with ID-based sign-ups and optional SOS features.

• Convenience: Real-time ride requests and scheduled rides for early classes, late evenings, or events.

Who Benefits:

• Students → save money, reduce commute stress, and feel safer traveling with peers.

• Parents → peace of mind knowing rides are limited to verified campus members.

• Campus Community → less traffic at the gates, fewer parking problems, and a more sustainable commute culture.

Business Model:

1. Pilot Phase (Free): Start as a student-only app/WhatsApp integration to validate usage.

2. Scale-Up: Small service fee per pooled ride (₹5–₹10 per rider).

3. Expansion: Partnerships with local auto unions/cab drivers for guaranteed availability.

4. Premium Features: Priority bookings, group ride scheduling, or “subscription packs” for daily commuters.

Why This Matters to Me: As a student, I’ve seen friends overspend on commuting and even miss classes because of transport issues. This idea combines affordability, safety, and sustainability while creating a stronger sense of community. It’s not just about cheaper rides; it’s about making campus life smoother and more connected.

> The Real-World Problem We’re Solving

 Millions of books sit idle on household shelves while students and casual readers hesitate to buy new ones. Public libraries often have limited hours, membership fees, or outdated collections. Result: valuable knowledge and entertainment stay locked away, and paper waste grows as new books are printed to replace unused copies.

> Gaps in Current Solutions

  Traditional Libraries: Require formal membership, fixed timings, and municipal budgets.

 Online Marketplaces: Involve shipping costs, waiting periods, and packaging waste.

 Charity Drives: One-time events with no sustained exchange or community interaction.

> Who Benefits

 Students & Avid Readers → Free, walk-up access to fresh reading material.

 Neighborhoods & Cafes → Increased foot traffic and stronger social ties.

 Environment → Reduced paper demand and landfill waste.

> Why This Matters to Me

 I’ve always loved discovering hidden gems in friends book collections. During college, I watched classmates skip good books simply because they were too expensive or out of stock. A simple neighborhood swap makes literature truly shareable and keeps stories alive.

>Technical/Design Innovation

 Open-Access Micro-Libraries: Weather-protected wooden or recycled-plastic shelves placed in lobbies, parks, bus stops, or cafés.

QR Tag & Group Chat: Each shelf has a QR code linking to a lightweight WhatsApp/Telegram group so users can post new arrivals or requests without an app download.

Community Steward Model: Rotating volunteers check the shelf weekly, ensuring books remain in good condition and the space stays tidy.

✨ BookLoop turns unused books into a living, everchanging library no membership cards, no late fees, just the joy of sharing stories.

Trash to Energy 

Food waste isn’t just about a plate of leftovers being thrown away—it’s one of the biggest global problems affecting our environment, economy, and society.

When food ends up in landfills, it doesn’t just disappear. Instead, it decomposes and releases methane, a greenhouse gas that traps heat over 25 times stronger than CO₂. Shockingly, if food waste were a country, it would be the third largest emitter of greenhouse gases in the world! 🌍🔥

And it’s not only the air we’re polluting—think about the resources wasted. Every meal tossed away also means water, energy, and fuel used to grow, cook, and transport that food are wasted too. From hostel messes and restaurant kitchens to wedding banquets and everyday homes, food waste happens everywhere.

 Most existing food waste solutions have big gaps. They’re often too large, bulky, and not practical for household use. Composting, for example, does create humus for plants 🌱, but it doesn’t give us something we can directly use—like energy.

On top of that, many current technologies are inefficient and space-consuming, making them difficult to adopt on a wide scale. What we’re still missing is a direct, portable, and efficient way to convert food waste into usable energy.

 That’s exactly what the solution below is designed to do.

A “Trash battery”: a household device where leftover food is dumped and converted directly into electricity using electro-active nanomaterials and microbes. We dump leftovers, food, peels into the device where the engineered microbes eat food and release electrons which is stored in form of electricity in  battery. Special nanomaterials capture these electrons instead of losing them as heat.

This can also be made portable for rural areas or disaster zones.  

We can integrate this battery with AI and IoT Sensors.

The IoT Sensors measure the amount of food waste, energy generated, battery charge level and conversion efficiency. You can improvise the sensors also track temperature, odor and microbial health. We can add pH sensors too to detect tracks of acidity, gas sensors to check leakage, voltage current sensors and microcontroller.

With help of AI Layer, you can learn your households waste patterns, also suggesting when to dump for maximum output and can also help you detect any fault in the system.

You can also have mobile app dashboard which shows how your using this energy in your household. Gamified tracking encourages people to waste less leading to behavioral change,

Like “Todays leftovers have charged your phone to today”,

 “You turned 500g of leftovers into 8Wh of clean energy 🌍⚡ You saved the same CO₂ as planting a tree for a day!”

Data aggregation can help cities, researchers or green energy companies.  Along with that you can add alerts “Needs more food for generation of electricity” OR “More food dumped”

This solution doesn’t just energy power but also teaches users how to waste less and use energy smartly. Reducing food waste is one of the simplest yet most powerful ways we can fight climate change—while also saving money and resources.
