Self inflating tire invention

-D- came across this a while back and forgot to send it out. A company has developed a self-inflating tire consisting of a peristaltic pump between the rim and tire and as the wheel rotates if forces air into the tire, with a valve dictating the pressure. Good use of existing movement and maybe a way to keep your commuter bike tires constantly inflated instead of having to break out the pump every few days. Too heavy for a road bike, probably not durable enough for a mountain bike. How much power does it sap? I don't know. I'm sure a sports car company will want to figure it out though.
