This generator was built using a 3 horse power Briggs and Stratton horizontal shaft motor, a GM 65 amp automotive alternator (with built in voltage regulator), a used car battery, a pulley and V-belt, a 12 volt cigarette lighter outlet...
A team of researchers from Stanford University unveiled an easier and more efficient way to strip hydrogen atoms from water molecules on Thursday. It's s
Solar aviation is still in its infancy, but it's getting better all the time. We might never see big passenger airplanes being solar powered, but there's all kinds of other cool stuff that can be done with this technology.
[social_buttons] Revetec, a little known company from the Gold Coast region of Australia, may be on to something huge: they've created an engine that is 50% smaller, 50% lighter, has 50% lower emissions and is cheaper to manufacture than a convent...
A lack of progress for battery technology is (arguably) the single biggest barrier for gadgets, electric vehicles, and the power grid. But there's hundreds of researchers, entrepreneurs, universities and large companies working on battery breakthroug...
This is one of the early Stirling models from Solar Engines in Arizona, purchased in 1980 and used for many hours over the years. The connecting rods have been rebuilt at least twice and the displacer now has a set screw locking it to its shaft since...
SECOND PHASE OF PRECOOLER TESTING COMPLETE -
Researchers have demonstrated an innovative "self-powered" method of producing hydrogen that may revive interest in fuel cell technology.
A prototype of a new kind of solar energy generator uses a water-filled glass ball to concentrate the sun's energy on a photovoltaic panel and boost efficiency by up to 35%.
