Hydrogen on Demand Evidence Sizzles from Arizona to Missouri
While the critics are talking about the laws of thermodynamics, inventors of hydrogen on demand generators from Arizona to Missouri are helping motorists save gas and emissions.
Run Your Car on Water Review - Truth or Fiction?
With the recent increase in fuel price, it has become absolutely necessary for everyone to get an alternative source of fuel that may be complemented with gasoline and diesel in order to decrease the amount of money spent on fueling our cars. As we speak, there is a new technology that can help us to solve that problem. Before you say: "Yeah another costly alternative", read this run your car on water review.
Run Your Car on Water
Run your car on water is a technology which helps car owners spend a lot less on fuel by adapting the water fuel technology which allows to increase gas mileage. This is done by harnessing the electricity in your battery to split the water molecules and thus cause your car to run on hydrogen.
Amsterdam and Rotterdam unite for hydrogen
The local authorities of Amsterdam and Rotterdam have set up a National Hydrogen Coalition, which will include companies, knowledge institutes, civil society organisations and governments, working together towards the large-scale application of hydrogen.
Video: Team Fate - Designing the Next Generation Hybrid
Students at the University of California Davis Hybrid Vehicle Research Center have been creating plug-in hybrids for national competitions for some time. "Team Fate" members Jungers and Kaufman describe how they "gut" the drive train of a standard vehicle, replacing it with an electric motor, a bank of batteries, continuously variable transmission, and some smart electronics. The resulting vehicle runs on electricity, assisted by a much smaller flex-fuel internal combustion engine only when needed.
Revolution in Hydrogen Cars - 650 Miles Per Tank
A team at the Lawrence Livermore National Laboratory have revealed a potential revolution in hydrogen cars, after driving 650 miles on one tank of liquid hydrogen - a new world record.

HHO Generators – The Surge Is Working
Despite what critics say, HHO generators are helping car owners save gas and reduce emissions using water and hydrogen technology.

Honda makes first hydrogen cars
Japanese car manufacturer Honda has begun the first commercial production of a zero-emission, hydrogen fuel-cell powered vehicle.
The four-seater, called FCX Clarity, runs on electricity produced by combining hydrogen with oxygen, and emits water vapour.
Japanese Car Runs Exclusively on Water!
The Japanese company Genepax has unveiled a car that runs exclusively on water. They even have a working prototype that was showed off in front of the press. They claim that using only one liter of water it can run with 80km/h.
$150,000 Sportscar Runs on Water and Gasoline

Ronn Motor Company has proven what thousands of amateur energy enthusiasts from around the world keep researching in their garages for years: that it can run a gasoline sportscar (Scorpion) on both hydrogen and gasoline, mixing them on a 30 to 40 percent ratio.
