HyTech (nickname for Hydrogen Technology Applications Inc) claims a process of converting H20 to HHO, producing a gas that combines the atomic power of hydrogen with the chemical stability of water.
A fuel economy enhancement application is presently being pursued as well.
In addition to marketing the H2O Model 1500 unit as a welding, cutting, brazing and soldering device, HyTech intends to promote the underlying technology utilized by the H2O Model 1500 Gas Generator as a fuel-generating device in other high volume applications primarily through licensing arrangements.
