 I use thermal electric generator tiles so it harnesses this thing called the seabag effect. Your hands contact the tiles which generates an electric current which powers these lights. In a lot of the developing world there's harmful microorganisms in the water. These can cause all kinds of sicknesses. You can get like seriously ill and die. I think that water is such a precious commodity and with global climate change occurring right now access to water is going to be more difficult to obtain. The thing that I thought I could have the most impact on was providing clean water for people. As a young person, Yash was always very curious. Yash as a child he was very talkative. He always started off with I have an idea. I originally wanted to do explosive ordnance disposal but I couldn't do it because I'm colorblind and you can't cut the red wire if you don't know which one is the red wire. I want to fight. I want to do good even if I'm not part of the military. That's still something that I like I strive to do. I've wanted to do something with water for a long time. The original invention was a water bottle that purifies water using the heat of your hand as a power source. You have to hold like a water bottle anyways so as you hold it it'll power the purifier and then ultraviolet light is what purifies the water by killing microorganisms in the water. So you just hold it for a few minutes and then your water is purified. Without water the max you're gonna live depends on the climate you're in is three days. If you're like a marine on a mission you can definitely use a clean bottle to like get water from like any stream really any body of water you come across it'd be drinkable after that. Our gear is what brings us success. My fight is kind of an internal one. I'm gonna be living in this world for the next 70, 80, 90 years like I want it to be a world that I want to live in. Even just helping out like one or two people that's like enough positive change to like make the world a better place.
