If you like to travel with bike, then you might love this “Urban Hotel” design. As a well thought-out solar-powered ‘green’ hotel, Urban Hotel itself is solar-power and features rainwater recycling system and a bicycle in each room, to help visitors explore the city. While the bike is in the room, it acts as an exercse bike that converts the bike’s padealing into kinetic energy to power the room and any extra energy is used to deduct rooming costs. If you get enthusiastic enough, for all you know, you could end up renting the room for free! Apparently all your pedaled miles get converted to energy savings and can be redeemed against the room rent. Sweet! [source]
