Solar
Idea
editSolar energy projects start with being able to aim solar light at a target and cook something like a frozen pizza. Then they branch out into hot water systems. After that the goal is to begin working with small solar cells. Working with lasers to power them and developing robots that can be powered by lasers. Typically these are robots climbing a rope and compete in a space elevator competition. The other expensive option is to design how adding solar cells to a university building.
