Interesting Advances: Plastics That Become Fuel, and Cars That Clean the Air

It seemed so simple.Take some plastic and drop it into thiscontraption, add heat, and out comes diesel fuel in petrol that can instantly be used to run a diesel generator.Surprisingly says inventor Christofer Costes, it is that simple.

Only a kilo of plastic gives a liter of liquid. 

It's separated between diesel and petrol. The team that put this device together says the goal is to keep the units small and affordable that should allow developing countries to create fuel and help cut down on plastic wastes.

The mission of this machine is to collect plastic waste especially in developing countries and to create value and jobs. We want the model to be economically sustainable, so it can be duplicated more and more as time goes by. And this is the Nexo, a new fuel-cell car fromHyundai.

Product managers Sylvie Childs says it's only emission is clean oxygen. To make the car run, you need oxygen and hydrogen which in the fuel cell stack, I mixed there's a chemical reaction and that produces electricity.

Stack 一堆，一摞

To get oxygen, we don't carry the oxygen on board. We use the oxygen that is contained in the air as we drive through. But that oxygen has to be incredibly clean, so it's run through three different filters before it's used to help power the car, and then it's sent back into the atmosphere, cleaner than when it went in. The Hyundai engineers say driving 1.6 kilometers in their Nexo removes the same amount of pollution that a diesel truck puts into the atmosphere every 3.2 kilometers.
