I decided after a long thinkig, to chose two heros: Aviva Presser Aiden and Hugo Van Vuuren. They created a technology that generates electricity from soil microbes to power LED lights, cell phones, radios and other devices.
By extracting energy and light from dirt, that exist in everywhere. Energy is the start point for lots of changes.
I knew then on Pop! Tech, I will try to follow these two revolutionaries and see what they do.
