"From next Monday, those staying at the 366-room Crown Plaza Copenhagen Towers will be encouraged to head down to the gym to spend time on its new fleet of electricity-generating exercise bikes. The bikes have iPhones mounted on the handlebars which monitor how much power is being produced and fed into the mains supply of the hotel. Any guest producing 10 watt hours or more will be rewarded with a free meal."
How’s this for innovation in the hospitality sector? A Copenhagen hotel has hooked up iPhones to exercise bikes to deliver extra power. Brilliant.
