    Car Roll Water
Click For Summary
The discussion revolves around skepticism regarding a car that reportedly runs on water, as presented in a Reuters video. Key points include doubts about the feasibility of extracting usable energy from water without an external energy source, which contradicts the first law of thermodynamics. Participants express concern that the claims of the car running for an hour at 80 km/h on just one liter of water may be misleading or fraudulent. There is speculation that the technology might involve metal hydrides, which require energy to produce and are not a sustainable fuel source. Critics highlight the lack of transparency regarding the car's emissions and the actual mechanism of energy generation, suggesting that the media's portrayal is sensationalist and potentially harmful. The conversation emphasizes the need for scientific scrutiny and independent testing to validate such extraordinary claims, with many participants advocating for a cautious approach to believing in such technologies without substantial evidence.

The law of conservation of energy is un-American, write to your congress person and demand that they repeal it now!

ps. I love the first comment to that story !
"I object to your headline. Bull ---- has been a well known source of generating power for centuries. It is well known that burning the cowpies will produce heat that will help keep one warm in winter"

So what is the closest thing to a car running on water that isn't a hoax?

Earlier, my post count was constant for the longest time, now its decreasing... kinda pointless, but maybe the glitch is a result of something more serious?

Cars running on hydrocarbons. Cars running on batteries. Cars running on hydrogen fuel cells. Cars running on photovoltaic cells.

A boat running on water.

Sorry didn't realize that bovine exement fuel source was an obscenity.
In my first amendment defence - I was quoting!

The secret to the water powered car

Actually there is no secret. They are using an off the shelf metal hydride process to produce a small amount of hydrogen. Run through a fuel cell it produces an underwhelming 10 amps at 30 volts max.

300 watts? It is a wonder the vehicle even moves.
