Idea: LACMTA Turnstiles = Electricity

If the MTA is going to install turnstiles to take tickets for the Red Line, they might as well make them able to generate electricity. Each time someone turns them, they should be able to trap that energy perhaps to operate the stations if nothing else. Not sure if that is feasible but they need to figure out a way for them to pay for themselves.

Another idea that came up this week sent to me by a colleague and friend was the ability to use excess body heat from subway stations to heat buildings. Sounds kind of gross to me, but if it works...
