Air-Purifier Bike
The Air-Purifier Bike has one of those strange designs that also address problems in our society – this one being air pollution. Talk about two for one! Not only are you using transport that doesn’t use gasoline, but this bike also filters the air and generates oxygen. It has an air filter that screens the air for pollution and dust. Not only that, but it also has a photosynthesis system with an embedded water tank that produces its own oxygen. As you ride the bike, it cleans the air and releases it back towards the cyclist, so you’re basically getting rewarded for using the bike. Additionally, when the bike is parked, the air purifying function continues with battery power (Conceptcus)
