The Crowne Plaza Copenhagen Towers in Copenhagen, Denmark, is giving free meals to its guests who are willing to pedal on two exercise bicycles hooked up to generators. The generators along with solar panels provide electricity for the hotel. The meal they receive is valued at about $44.
So this green project generates free electricity for the hotel, good exercise for its guests, and an overall reduction of carbon footprint.
Crowne Plaza is part of InterContinental Hotels Group (IHG), which trades on the New York Stock Exchange.
