Hydrogen power

The advantages are density of power.. Hydrogen compared to AA batteries is rather dense. The disadvantages are cost and containment (As noted by a prior poster) and where does the H2 come from?

THey split water to get it,, Ok, how do you do that? Why you take standard house power, rectify it, and feed it to a container of water via a couple of electrodes, You collect the gas that boils off ONE of them (The other one is oxygen) and you then compress it.. All this takes electricity, A LOT OF IT, relative to what you will recover.

Thus not practical for RV use.

Nice curiosity, but I wouldn't touch it with an oxygen molecule...Still perfecting my sea water to hydrogen cold converter!

Before you jump into any hydrogen technology, look very closely at what hydrogen plumbing and hook up system you need. Hydrogen molecules are the smallest of all and we found when handling it in a lab, it will migrate through (leak from) most normal gas connections. Then if you have places that trap the loose gas, you're looking at flash fires and/or explosions. Handling this stuff like LP gas is just not going to work. It take special and expensive equipment and care.

Exactly! I remember reading that when first invented, people thought the 'Horseless Carriage' was just a curiosity that made a lot of noise and served no real purpose.....

so, yer sayin they have a real purpose?:B

The Other piece appears to be a glorified Battery Charger! So what makes "it" work 115 Volt AC?

Neat idea,

Still kinda expensive, but the prices should come down in a few years with mass production. It would be a great way to store solar energy for use during "Peak hours". Such as when the sun is not shining and the wind machines have stopped.

Yes there are 1 million watt fuel cells in use today. And it is well known that you can use the fuel cell to make hydrogen by applying voltage to the fuel cell. Even some in the 15 MW to 50 MW size. They are best used while also being able to use a lot of hot water, such as being close to a greenhouse that can use the excess heat that is also generated while running the fuel cell.

Home Power Magazine has done a few articles about fuel cells over the years. One is a storage tank using a chemical inside, that allows much more hydrogen to be stored without increasing the pressure to high. However it will heat the tank while increasing the pressure, and cool down when taking out the hydrogen.

Lots of interesting things going on with hydrogen. But not all of it is new. I was watching a film when I was in grade school (many years ago) where a guy was running a briggs and stratton engine on hydrogen, with a face mask attached to the exhaust muffler. The engineer who built it said the exhaust is cleaner than the air going into the engine.

Hi Mr. Wizard,

It is even worse. To recharge the "reactor" cells you need the other device on the page--which costs an additional $279.99.

5v 2 amp

expensive way to recharge your iPhone

even at 12v, it would only be a float maintainer, better off spending the $170 on solar

They are around. There was a company selling these for news crews with an Anton-Bauer connector on it several years ago Great idea until you try and take it on board an airplane.
