I once visited a home that had a stationary bicycle hooked up to a generator of some sort. When pedaled, the bike would generate electricity. Does anyone know what this is, where to find one and how efficient they are?
Your post made me curious so I searched for bikes that generate electricity. Here is a good source of information that I found Log In Of course I can't recommend it since I haven't used it but if you have some money to spare, you can check it out and see whether it helps to reduce your electricity bill.
