Japanese company Genepax presented its eco-friendly car that runs on nothing but water. The car has an energy generator that extracts hydrogen from water that is poured into the car's tank. The generator then releases electrons that produce electric power to run the car.
The car can run for an hour at about 50 miles per hour on just a liter of water. Genepax, the company that invented the technology, aims to collaborate with Japanese manufacturers to mass produce it.

Yeah, right. And where does the electricity come from that extracts the hydrogen? Do you plug the car in overnight? The article doesn't say.
Only a fool would believe that you can somehow magically extract power out of water without any input.
Also, the photo in the article is the same as this one except there appears to be a driver with a hockey mask in the car. What's up with that?
I suspect this is an April Fools joke, still lingering.
Same as every single "water powered car" that's appeared over the years. None of them have ever worked.
Water goes in ... so what comes out the other end? For a chemical reaction to produce usable power, a change must occur, usually the component parts moving from an arrangement with a high potential chemical energy to a low one.
Water already has a pretty low potential (it's the output of the hydrogen + oxygen reaction in a fuel cell after all). So what could it combine into that has a lower state? Not a great deal - that's why it's one of the most abundant chemical compounds on earth, and arguably in space.
Also if it just produces water out the "tailpipe"... then you could get phenomenal range simply by recycling the "exhaust" back into "fuel" with a simple pump. Or incorporating one of these into a fuel cell car to extend the range.
I could believe this is maybe a hydrogen cell car that's been given an unfortunate and misleading name, but no more. Also their testbed is a G-Wiz (aka Reva), not usually the host of particularly high-powered drivetrains... its strongest one tops out at about 14hp and manages maybe 50mph. You could put a much lower powered motor in it and still make a testbed that would impress gullible journos on an indoor track whilst only needing a very small, easily hidden battery pack.
