|Chris Malloy of Australia claims to have built a functional hoverbike. Yes a hoverbike! Powered by 1170 cc engine is capable of lifting 270 kg off the ground. Expect this thing to be able to travel at upwards of 170 mph, and you can take it to 10,000 feet (or even higher). The machine is quite light, weighing only 110 kg when dry, thanks to a body made of carbon fiber and kevlar-wrapped foam.
