Is the water-fuelled car really here? Sounds too good to be true. They say it can run on a liter of any old water for an hour at 80km/h. Either there's some big downside, or this will change the game.
Of course there are doubts already.
You bet there's doubt! Show me pure water burning in ambient conditions, with no external energy input, and my doubts will be put to rest.
Just assume for an instant that someone has developed a bug capable of separating water into hydrogen & oxygen. Can you imagine the consequences should that bug be released in the environment? Would make the launch accident in the "Rejsen Til Saturn" trailer look like a minor glitch...
Just thank God its a hoax. Achieving their claims on our planet would be like discovering fire on a planet with an atmosphere composed of oxygen and methane.
