Genepax (Japanese Water Car Company) Shut to Silence
In June last year, everyone may have heard the buzz about a japanese water car. The buzz was about Genepax, a company from Japan who had claimed that they invented a revolutionary system that splits water into hydrogen and oxygen and then uses a fuel cell to recombine it and generate electricity. That electricity would have driven a car, fact that they demonstrated in front of the press at that time.
Hydrogen From Water – 3 Production Methods
Getting hydrogen from water is one of today's hottest and fastest-evolving areas in the renewable energy world.
The basic methods for hydrogen production, though, have remained the same...

Mechanical Battery – Flywheel-Powered 90% Efficient Energy Storage
We have been so focused on chemical storage systems lately, that some us forget other old, seemingly more efficient, mechanical batteries. Such a battery is the flywheel. Several successful experiments have been carried out in the last 50 years, and the flywheel's applications ranged from acting as a UPS for a hospital to putting an entire train to movement and then to cruise speed, only by its power.
Daniel Dingel’s Working Water Powered Car
This is a REAL car working with REAL water... through electrolysis. It seems that the re-mix of hydrogen and oxygen actually produces more energy than it takes to split them! Daniel Dingel from Philippines has made 100 motors work on water and wants to spread them to the world, so any country can reverse engineer it and make something better off it. It's really amazing how we were taught since kids that water only kills fire... not always!
