CHSV Solvers' Fest 2021

Highlight solution prototypes and award winners from CHSV Solvers’ Fest 2021 !

1. The Best Prototype Award
Team Probsol (Dyutimaan Krit, 8C )
Change-making vision:
The change I want to see is more implementation of dynamos in cycles and other equipment like treadmills. I want to make this happen because even though this product already exists, it is difficult to install and use. I want to make a prototype that can be made and installed easily in different types of cycles/equipment.

An average 30 minute bicycle ride can produce around 33 watt-hours of energy. Therefore, even if 100 people cycle for 30 minutes, the energy that can be produced in one day is around 3.3 KWh. If this solution can also be implemented in treadmills, there would be even more electricity generated.


The amount energy that can be generated per day is around 3 KWh, if the number of cycle rides is 100 and the duration is 30 minutes
The stakeholders that could help me amplify the work I have put in could be bicycle companies like Hero, Btwin, Hercules etc.

2. The Best Campaign Award
Team World Changers (Tanisha Kambli , 6C)
Change-making vision
The change I want to see is e-waste reduced which is very harmful to the environment and humankind in India. I want to make this happen because e-waste when disposed can pollute air by the smoke that comes from burning electronics to get copper. When E-waste is not disposed properly it causes toxins to pollute soil and water.
