Powered by an Arduino UNO for bridge automation and a Quarky board for smart irrigation, the system also uses soil moisture sensors and a water pump to ensure precise watering for plants—wasting zero water. With the potential to save over 9.02 billion liters annually, RainCatcher 2.0 turns existing infrastructure into eco-smart assets without any new construction. It’s simple, scalable, and student-built—a bold step toward water-wise, greener cities.
Generating Electricity From Human Kinetic Energy-Urban Park
The Urban Heat Island (UHI) effect is heating up our cities, worsening climate change and putting vulnerable lives at risk. To address this challenge, Team Green Circuits presents an innovative solution that reimagines public parks as sources of clean energy. Our concept integrates renewable energy-generating playground and fitness equipment into urban parks, turning recreation into power production.
In our design, merry-go-rounds, swings, and see-saws are fitted with DC motors that generate electricity through motion. Outdoor fitness equipment like treadmills and exercise bikes convert human activity into usable energy. Additionally, solar panels on benches and tables collect sunlight to power lighting and park amenities.
This green infrastructure not only helps cool the city but also generates clean electricity for park lights, charging stations, and water features—reducing reliance on fossil fuels and minimizing maintenance costs. Beyond functionality, it encourages community engagement and educational awareness, transforming parks into living labs where people experience sustainability firsthand.
Our urban energy park blends technology, play, and climate action. It’s more than just a green space—it’s a self-sustaining ecosystem that empowers communities and sets a new standard for smart, climate-resilient urban design.
Traffic Management System
Mumbai, one of the busiest cities in India, faces severe traffic congestion due to its rapidly growing number of vehicles. Long commute times, fuel wastage, and delayed emergency vehicles have become everyday struggles for Mumbaikars. A major issue is the rigid, static road dividers that do not adapt to real-time traffic conditions, causing inefficiency in lane usage. To solve this problem, Team Traffic Dynamics has developed the Automated Lane Divider System (ALDS), a smart and flexible solution designed to optimize road space dynamically.
The ALDS works by automatically adjusting the number of lanes available in each direction based on traffic demand. The system utilizes an Evive board, keypad sensor, and servo motors to create a responsive traffic management system. Traffic police can manually input a password on the keypad sensor, allowing them to control the lane adjustments as needed. The Evive board processes this input and sends signals to the servo motors, which physically move the road dividers, increasing or decreasing lanes in real time.
This innovative system has multiple benefits. It reduces traffic congestion by making better use of existing road space, ensures faster access for emergency vehicles, and minimizes fuel consumption and pollution by reducing the time vehicles spend idling in traffic. The ALDS provides a flexible and scalable solution that can be implemented in cities struggling with traffic inefficiencies. By making roads smarter and more adaptive, this system has the potential to transform urban mobility, making daily commutes smoother and more sustainable.

Clean City Tycoon
According to the IEA or International Energy Agency, cities account for around 67% of global energy consumption and more than 70% of global energy-related CO2 emissions. This reality underscores the urgent need for more efficient energy use to secure a sustainable future.
Through a nostalgic 90’s retro video game graphics, Clean City Tycoon aims to educate the younger generation who enjoy playing video games to think about how to make our environments a safer place to live in through clean energy. Players learn that different energy options are beneficial in different situations such as solar panels that withstands during a brighter environment and wind turbines that withstands better in a windy environment.
Using these different options, players must adapt their city and manage their budgets according to the different weathers on the day-to-day basis. This allows players to strategically allocate their funds for the renewable energy sources in regards to each different environment while learning about howach energy source would work in those different weathers. Players don’t just manage a city—they also see the consequences of their decisions, such as reduced CO2 emissions or energy shortages, directly impacting the virtual world. This connection fosters critical thinking about real-world sustainability, making learning about clean energy both impactful and enjoya
Eco Guard Grey Water Sensor
Eco Guard Grey Water Sensor is an AI-powered system that monitors, analyzes, and reports grey water quality in real time. Using sensors to detect water turbidity, it processes data via Quarky and PictoBlox, providing instant visual feedback to optimize water reuse efficiently.
Waste Management Support
We often see overflowing trash bins filled with trash, especially in places like malls, schools, or parks making these areas dirty. People feel weird when throwing trash in these dirty places and sometimes, people don’t want to throw trash in these trash bins and leaving trash on the floor instead, making areas dirtier.
This project helps to solve these problems by telling you if the trash bin is empty, half full, or completely full using an ultrasonic sensor. When the trash bin is full, it will tell you by using a buzzer to play a sound so it can be emptied quickly. It can also open automatically if you want to put trash so you don’t have to touch the trash bin.
It has other features in the control panel such as testing the buzzer, resetting the ultrasonic sensor, and a percentage counter to tell you how full the trash bin is so you can always keep track on how full the bin is.
Using this project, keeping spaces clean becomes much easier and more efficient saving time and effort. You don’t need to chec regularly to know if it is full anymore while keeping these areas neat and tidy, making waste management less of a hass
The 3 in 1 Tree
*Description*
The 3 in 1 Tree is an artificial tree, a smart streetlamp, and a sitting bench all in one product.
I used microalgae to clean air pollutants just like real trees, and I also used solar energy, artificial intelligence, and coding for the LED lights to be smart streetlamps.
Microalgae produces half of the oxygen in the world and is about 50 times more efficient than normal trees. It’s also a liquid, so it saves more space since it can fit in one container, and can be placed in urban pockets in a big city. It doesn’t take much time to grow, so it can help us address global challenges because of the rapid air-pollution rising in big cities.
The Solar Panel charges the battery that turns on the LED lights to be more eco-friendly.
There is a Relay as a switch connected between LED and Battery controlled by Arduino which has been programmed in Pictoblox using Machine Learning.
Using a Webcam, it can see whether there’re people, vehicles, animals, or nothing on the street.
The LED lights soff during the day, turn on at night when there are people or vehicles, and stay off at night if only animals or nothing is around.
This makes the 3 in 1 Tree smarter and saves more energy.
I hope this innovation can bring sustainable solutions for a better future in modern society.
