I think that it would be a great idea if there were a machine under the desks, sort of like an exercise bike. I have heard that companies are starting to use this to help their employees. But instead of just helping the employees get an exercise at work, it would also we supplying energy while doing it. So, the more the employees exercised the more power the company would have without having to pay for it. The company would save money, help the employees health, and also it would be environmentally profitably.
