H2O car Ping!...........
Why didn't somebody tell me that the Second Law of Thermodynamics had been repealed?
Somewhat reminiscent of John Galt’s engine which extracts static electricity from the air.
Whoever wrote the article seems to believe in perpetual motion, or they’re a shyster, or else they’d have answered “the question.”
The distinct advantage over solar is that you can guarantee the input and therefore the output.
Or what some call:

"Is "Pie in the Sky" as tasty as "Floor Pie?

one horsepower = 745 watts.
So this cell (300W) will produce less than half a horsepower. Yes... I can see the potentional in powering slot cars...
Unfortunately, since the system is Japanese, it attracts monsters bent upon destroying Tokyo whenever it’s turned on. It’s a good idea, in theory, but falls short in actual application.
From the picture, it appears that a one cubic foot power device generates 120 watts.
120 watts = 0.16 HP.
A one cubic foot gasoline engine, if you don't include all the air filters, exhaust piping, etc. probably could generate 15-25 HP. Like a "typical" riding lawnmower engine.
So then, the energy density as compared to a gasoline engine is, broadly - about a ratio of 100:1.
So to buy a car with a 200 HP engine of this type would take an engine 100 TIMES LARGER than your current gasoline engine.
Get back with me when this can be mass produced AND they can also shrink it by about a factor of 50. That might actually be possible some day. Right now, it's a laboratory anomaly that they appear to be using to power a golf cart.
“300W generation system mounted in a luggage room “
That won’t even power the subwoofers.
As Slings and Arrows points out, the energy comes from the electrode assembly material, which is used as consumable fuel. Water is not the energy source here. It is thermodynamically impossible to break water into hydrogen and oxygen and then get a net energy gain by reacting the hydrogen with oxygen in the air.
Someone should find a way to harness the hot air that comes out of Washington.
746 watts = 1 horsepower
300W is then .4 Hp
A 300 hp truck would then need 750 of these systems
A 150 hp van / car would need 375 of these systems
That might get a tad expensive.
Water—despite the flooding in the Midwest-— IS NOT in abundant supply in the western half og the country.
Are we going to deny the use of water to grow our food so that the water can be used for fuel?
The Ethanol debacle is really hitting the skids, IMO, with the flooding and hail and heavy rain ruining the corn crop in about 7 states that are high in corn production. There will be no or very little crop of corn this year, and with any surface crop that is subject to Mother Nature, it is an uncertain source for fuel or food each and every year. Where are the Ethanol refineries going to get their raw materials this year???
How much power does it take to produce the fuel electrode? If it’s more than the unit puts out, they’ve invented a “perpetual backwards machine”.
120W. Just enough to run my two desk lamps!
Everything after the MEA can be ignored until the MEA itself is explained.
Sounds like the ideal solution to the Man-Made Global Warming Problem
