Friend is Determined to figure out how to make this useful!

Bout this as a gift for a good friend of mine. He has it on his desk as as it sits there spinning (incredibly fast depending on the light source), he gets lost imagining everything that he should be able to do with it from free electricity to all, to powering moon bases! It may not have helped his productivity at work, but it has helped his creativity. 10/10 would recommend to anyone who has a few moments to stare off into space at work.
