This is not a joke. There is now an engine developed that means a car can run on air? Surely this is the Mecca of all engine development? Not only does it keep the climate change rabble happy, but it is ludicrously cheap to run.
OK, so it only goes 68mp so far, and yes, it probably takes four days to reach that speed. But the possibilities are endless are they not? The only downside is that it's French, which means the bits inside will probably fall off in the first week.
