use nanotechnology to make your own solar power. by using Xerox’s photovoltaic silver ink and adding 50 nm graphene nanoflakes and aloe vera as the gel base you have a PV gel you can coat on an electrode to make a solar battery
In this video, I will show you how I made the world’s first 10 Ah battery pack. At 24V, this thing is a beast with 240 Wh of energy. With this, I have almost a quarter of a Kilowatt hour in the palm of my hand. (both the Dewalt and Milwaukee current best 9Ah batteries are only 180 Wh and it cost a fortune to buy those). Don’t judge this battery by its weight and size as my main goal is not for using it with my tools. Although it’s nice to have a tool battery that can last all day when you work on a long project. Stay tuned and I’ll show you my main purpose in the next videos. In the mean time, here’s the video to show you how I made a 4 Ah pack for tools: https://youtu.be/m1JU4IQ_ayw
