Energy from burning hydrogen to power a vehicle << energy needed to split that hydrogen out of water

We truly live in an age of miracles, yet barbarians, both foreign and domestic, threaten to ruin it for everybody.

The great thing about this is that the voltage required is very low, 1.5V or lower, and the anodes are made of abundant metals, not rare or expensive ones........................

hand crank your splitter ,then start your car , Perpetual Motion ,LOL

[Kirkwood]

The batteries come from battery bushes. Free for the picking.

“Although touted as zero-emissions vehicles, most of the cars will run on hydrogen made from natural gas, a fossil fuel that contributes to global warming”

Just stated like it’s a fact.

Mega Bump!

Hydrogen internal combustion power is a still born looser. No one well informed takes it seriously as a solution.

So they figured out how to overcharge a nickel-iron battery. That was a problem with those old batteries, they were pretty tolerant to overcharge, but they gassed out really bad, and you would have to replace the water lost. A dry cell at 1.56 volts is able to overcharge a nickel-iron cell at 1.2 volts, which happens to be close to the voltage required to split water into hydrogen and oxygen.

So, it’s Bushes fault?..................

[glorgau]

This too will be “proven” to contribute to global warming.

[Red Badger]

Hydrogen fuel cells are the target of this research...........

“Global Warming” = cover for the elites denying others the use of THEIR resources.

So...is there actually a net gain in power? Or will we have to keep burning coal to power the battery to power the catylist to convert water into hydrogen/oxygen?

[Sgt_Schultze]

the novel water splitter could be used to make chlorine gas

So a terrorist could quietly slip into the air handling facilities in any high rise and drop off a device which plugs into a standard outlet, turn it on and walk slowly away as inhabitants of the complex are poisoned.

There will always be a loss in power somewhere in the equation. The 2nd Law of Thermodynamics demands it.................

[smokingfrog]

I wonder if it will be practical to retrofit a battery powered car with a fuel cell?

[Red Badger]

They could do that now with a bottle of Clorox and Parsons Ammonia, two balloons and timer....................
