Environmental Hacks

Bad air, heatwaves, floods, water shortage and waste are problems we see every day. In this hackathon, you pick one of these problems and build something that helps solve it. It can be a problem in your city, your college or your home.

The hackathon runs online Thursday to Sunday, with an optional build day at DTU, Delhi, on Saturday, Oct 10. Limited seats, and you get workshops, project feedback, time with the Amazon team, and swag.
