Energy Bikes

They could help save the environment! BUT there is only one problem - it's VERY hard to pedal when you have to produce enough energy, say, for a mobile phone (with music on) and a tv. I know - I rode two different energy bikes at the Big Bang Fair !

This reminds me of a Business Insider article that I read, on the founder of Duolingo. The article is worth reading, and here is the relevant portion:

When he was 12 years old, Luis von Ahn came up with a plan to make gyms free.
People exercising on machines can generate electricity, he figured, and that energy is valuable. So why not eliminate gym fees, hook all the machines to a power grid, and sell the wattage produced to a major electric company? Everyone could go free of charge, the world would have a new source of power, and people would be healthier to boot.
"It turns out it's not a very good idea," von Ahn, now 34, chuckles. "People aren't very good at generating electricity. It's much better to charge a membership fee."
