Default Artifical photosynthesis

Putting sunshine in the tank

This is about "artificial photosynthesis" - using nanotechnology to make hydrogen fuel directly from water and sunlight.

By this method, "solar cells" could be made that once installed only use water and sunlight to create fuel that can be burned. The whole thing does not involve carbon based fuel.

It does not say what materials they need - usually these kind of things need rare earth minerals and a lot of energy and industrial byproducts to be built. We'll have to see what that impact is (total lifetime energy balance, total lifetime impact)

"Humans are storytellers. These stories then can become our reality. Only when we loose ourselves in the stories they have the power to control us. Our culture got lost in the wrong story, a story of death and defeat, of opression and control, of separation and competition. We need a new story!"
