Video: Crazy Inspector-Gadget-like (homemade?) vehicle sweeps streets outside of Beijing

Someone on vacation two days ago at Baiyangdian (two hours away from Beijing) saw this most peculiar helicopter-like road sweeper machine, which looks like something the driver invented himself. This wonderful invention sweeps everything -- pebbles, rocks, plastic bags, rubbish -- down to the side of the road. Whatever you don't see is not there, right? We think the inventor deserves top marks for innovativeness, but something tells us it is not going to get patented anytime soon.
