    Car Roll Water
Click For Summary
SUMMARY

The discussion centers around a Japanese car that reportedly runs on water, claiming to operate for an hour at 80 km/h using just one liter of water. Participants express skepticism about the feasibility of such technology, citing the laws of thermodynamics and the need for an external energy source to extract hydrogen from water. The conversation highlights concerns regarding the potential emissions and waste products, particularly sodium hydroxide, and questions the validity of the claims made by the media and the company behind the car.

PREREQUISITES
  • Understanding of thermodynamics, particularly the first law of thermodynamics
  • Familiarity with chemical reactions involving metal hydrides and water
  • Knowledge of hydrogen production methods and their energy requirements
  • Basic principles of combustion and energy conversion
NEXT STEPS
  • Research the principles of thermodynamics and their application in energy systems
  • Study the chemical reactions involving metal hydrides and their energy outputs
  • Explore hydrogen production techniques and their environmental impacts
  • Investigate the implications of sodium hydroxide as a waste product in chemical reactions
USEFUL FOR

This discussion is beneficial for engineers, chemists, environmental scientists, and anyone interested in alternative energy technologies and their practical implications.

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.
