Hydrogen power on the go

A correction was made to this story. Read below for details.

Think of it as a briefcase for electricity.

Houston-based Trulite is developing a portable hydrogen-powered generator, the KH4. Pour water into the unit, and it will crank out 150 watts of power, and 200 watts at its peak. While that won't run your house, it's enough to recharge power tools or a laptop or run a small appliance, according to company CEO John Goodshall.

A target audience for the device will be contractors, particularly ones who work on downtown skyscrapers. Power tools regularly sap their batteries. (That's why Powergenix and other start-ups are trying to market new types of batteries for them.)

To get around the problem, contractors either carry spare batteries, which can be expensive, or recharge them with gas generators. The fumes and noise of the gas generators, however, are often incompatible with downtown building requirements. Thus, Trulite hopes that contractors will opt to carry its unit instead.

And for those people who bring a generator to a campsite to watch TV? A portable hydrogen generator will eliminate the noise.

The active ingredient in the fuel cell is sodium borohydride. The material splits water molecules into hydrogen and oxygen. The hydrogen is then pushed through a membrane that extracts electrons. The sodium borohydride also stores hydrogen safely. Others are also working on similar solid storage systems for hydrogen.

"We control the flow of hydrogen," Goodshall said.

Once the fuel of the future, hydrogen now gets regularly panned by critics as being expensive and impractical. Advocates, however, say it could become an important green fuel when batteries or solar electricity aren't practical.

Hydrogen may be a niche, but its advocates aren't giving up. Horizon Fuel Cell Technologies, for instance, is promoting hydrogen fuel cells as a way to power boats on Swiss lakes.

Others have speculated that offshore platforms--decades from now--could harvest wave and tidal energy, turn it into hydrogen, and then ship it to shore. Offshore hydrogen would be used in those situations where it is impractical to connect a distant ocean platform to the grid. Toyota and Daimler-Chrysler continue to research hydrogen cars.

Trulite will release beta units soon, and the company hopes to start selling the KH4 in the second quarter of next year. The unit will cost about $2,000, which is far more expensive than a gas generator. A more powerful gas generator can be bought for $300.

Trulite's chairman is John Berger, a former Enron executive who is also behind Standard Renewable Energy, which sells energy-efficiency services and biodiesel.

 

Correction: This story incorrectly identified the active chemical in Trulite's hydrogen generator. It is sodium borohydride.

it's a start

as longs as they push their research further, depending on how sucessfully they market their product...

Detailed response on my CNET blog

I started to write a short comment here, but realized it needed
more detail than would be appropriate in a comment, so I made
this product the subject of my blog today:

Power Generator

If someone is looking for an inexpensive way to gererate power tools on the job or anything else for that matter, try looking into zinc power generators. I heard of them a few months back, manufactured by a company that has a stock ticker symbol of PWAC. Name is Power Air Corp. I haven't personally looked into it, but zinc is pretty accessable to operate a generator.

How long will this thing run a 15W Zonbu Mini-PC?

Wow, this may be just what I'm looking for.

I've been testing the Zonbu Mini-PC as a potential desktop replacement, and it works surprisingly well and better yet only sips 15W of power. Talk about green.

More details on the Zonbu on my blog:

Wow!!!

If you can push Hydrogen Molly Q's thru a membrane and suck out the electrons, what voltage do they come out at? Is it AC or DC? Couldn't you just use the filter on plain water and suck the electrons out of that?

Your explanations are great. They just leave me teeming with ideas. Thanks a lot.

Buy a whole bunch to power a car

Easy to do this.......

The fact remains the man who did make the hydrogen powered car in the 1980's was killed.

I am sure his patents are still valid and can be freely used. I refuse to pay for water when it is free!
