Bio-organic solar cells. https://en.wikipedia.org/wiki/Organic_solar_cell https://en.wikipedia.org/wiki/Organic_solar_cell These things, in theory, could be everywhere. You can bend some of them, so you could wrap lamp posts with them, cover cars in them, put them everywhere. I am confident that within 20 years, we will solve power problems with renewables like this, and we will have a major revolution in infinite-power designs, like illuminated clothing, power generating and emitting roadways, and servers embedded into everything, everywhere, for every reason. They are 17% efficiency, and they don't yet last very long, but the work is moving at a steady pace.
