New Fuel Cell Twice As Efficient As Generators 246
Hank Green writes "A new kind of Solid Oxide Fuel Cell has been developed that can consume any kind of fuel, from hydrogen to bio-diesel; it is over two times more efficient than traditional generators. Acumentrics is attempting to market the technology to off-grid applications (like National Parks) and also for home use as personal Combined Heat and Power plants that are extremely efficient (half as carbon-intensive as grid power.)"

These days the batteries are also measured while nog being used. When their are nearly discharged, they are charged automatically. This happens in a way so the life expectancy will be maximized.
Of course there's still Murphy's law, and batteries can fail a whole lot earlier!

List price for a 5 kW unit is $175,000. Present systems are still demonstration units and carry the cost associated with not only the system itself but some custom engineering which typically results from each customer's intended installation. Acumentrics normally provides site installation support and monitoring which is also provided in the quotation.
5kw Back up plan (Score:4, Informative)
I am planing a hybrid system for the house when we get one.
will consist of Outback inverters, batteries, little solar wind/panels and last but not least is a generator.
The idea is during a short power outage run off batteries - if it is a long one the generator will start up and
charge the batteries. the solar and wind will be added in stages starting with the pannels
Using CFL's for lighting and auto transfer of vital circuts to the back up system. ie Beer fridge
The idea is that the generator will run at 80-90% load instead of wide fluctuations of 10-90 % the difference is is 2 - 4 hours of run time to a tank so i will use less fuel during a longer outage.
Also being conservative on power consumtion during that time i can even extend my fuel supply
Can also get exaust to water exchanger and use it to help heat the house in winter if needed.
The big advantage is that i can handle larger surge loads then just useing a generator which would have to be 2 to 3 time as large for start up of motors and short peak loads. Ie well pump and sump pump were rural.
Will cost more then just the generator but is way less the $175,000

Wow, and at HomeDepot, I can get a 7kW Generator with a 12 hour run-time @ half usage, for around $550. Sure, it produces carbons, but, I'm willing to bet that if the price of gasoline doubled, I still wouldn't be able to off-lay the cost of the fuel cell in this lifetime.

Oh, did I mention that it should demonstrate the ability to SCREW over OPEC, Government, and Corporations?

Yep. That's also how they keep diesel particulate filters working. Every couple of hundred miles, raise the exhaust temperature for a few minutes, and you're good again.

As to whether you should wait for the next generation or not... that's always a tough call. At some point, you just have to stop and buy a car. Otherwise, you'll *always* be waiting for the Next Great Thing. It's a lot like buying a computer. You could make the argument that you should wait, since you know that things will be much, much faster at the same price in two years-- but in two years, the same thing will still be true.

Wow, cherry-pick much? How long did you Google to find countries that have the lowest possible fossil fuel consumption? Except for Japan, anyway. Percentage wise, Japan's use of fossil fuels (~65%) is almost as bad as the US (~71%).
Just for shits & giggles, let's include China - a rapidly industrializing country whose electrical conspution is and will continue to expand rapidly - with ~82% of their power coming from "conventional thermal" generation. Or the UK with ~74%. Or Australia (~92%), Netherlands (~90%), Greece (~89%), India (~83%), Mexico (~83%), Denmark (~82%), or Italy (~82%). (source [cslforum.org])
Hey look, I can be highly selective with my data too!
Here's an idea - maybe, just maybe, it is understood that the phrase "half as carbon intensive as grid power" only applies if the power comes from fossil fuel sources. Call me a radical thinker, but sometimes it's easier to consider the subtext than to throw yourself into a fit of self-righteous rage.

If I understand right, the flexible fuel use is one of the advantages of the high temperatures (along with non-catalytic electrodes that aren't adversely affected by carbon exposure), which allow the fuel to be broken down into hydrogen and other elements within the fuel cell, instead of in a separate reformer.
Most types of fuel cells being actively researched have comparable electrical efficiencies, some better, some worse. They're also all very big. The news is this company released a new model, an alternative energy blogger thought it was cool and wrote a few non-technical notes on it, and now half of Slashdot seems to think it is something revolutionary. It looks like a good product, but it's far from as significant as the summary implies.
By the way, I looked up the company's page on this product [acumentrics.com], which is much more informative. Also on the page are links to a spec sheet, suggested applications, and a couple pictures so you can get a sense of scale. These things are clearly a lot bigger than a typical 5 kW internal combustion generator.
The DOE has a decent overview [energy.gov] of solid oxide fuel cell technology.

The market for fuel cells is vastly greater than the market for RO systems. Poor people without clean water to drink still use energy. Relatively poor people that wouldn't think of getting a water filter use tons of energy. Even among the wealthy RO units aren't common. We could use fuel cells in so many areas. If it scales down we could put one in every computer, car, and house. There is such a massive potential market the economy of scale would be huge.
