We all like free stuff, especially free food. It's not quite "free," but at the Crowne Plaza hotel in Denmark, guest can earn a $36 meal voucher simply by riding a stationary bike for 15 minutes. The gimmick is part of the hotel's sustainability campaign. A 15 minute bike ride generates 10 watt-hours of electricity (for reference, 60 watt-hours is necessary to run a standard 60-W bulb for an hour). Check out the full Popular Science article here.
