Consumer Hydrogen Fuel Cells
axis-techno-geek writes: "Ballard Power Systems of Vancouver, BC (in Canada, eh), has stated that it will start production this friday of their consumer level Nexa(tm) hydrogen fuel cell (article here). The power module generates up to 1200 watts of unregulated DC electrical power that can keep going as long as it is supplied with hydrogen, and produces no toxic by-products (i.e. you can use it in your home). They also have plans for a 250kW unit. No price as of yet."
Thats just the right size for RV's. Lots of power their to run a computer, tv, and a few lights.
God, root, what is the difference?
I think there is an enormous opportunity for North America to move to a distributed power system. Imagine this: natural gas feeds into your basement fuel cell, where you generate electricity for your entire house, plus you crack some of the natural gas into hydrogen during the day, to fill up your fuel cell car when you connect it overnight. Wired's article The Energy Web has similar ideas (and an opening paragraph that is now quite eerie).
If that is the case why do they list a 'Lifetime' of 1500 hours? That's only ~62 days.. definitely not as long as it is supplied with hydrogen

The long term solution would be to wean the USA off of an economy dependant of international oil supplies.
While many oil and energy companies may want to retain control of their assets in the area, solutions such as Fuel Cells may ultimately be the most elegant solution to the situation.
Fine, if they want to be poor, we can let them be poor.
This is something that I think the Bush Administration should go after Hard. Unfortunately, he may have some conflicts of interest given the support he has received from these very same oil companies.

A fuel cell is only truly zero-emission if it is catalyzing hydrogen gas from zero-emission sources. 95% of our current supply of hydrogen comes from natural gas. So currently the fuel cell is only as clean as the natural gas reforming plant, effectively "burning" that gas and releasing CO2.
They're a great idea, but they're not zero-emission yet.
Can't you see that everyone is buying station wagons?
This is on topic... trust me! =)
The other day I heard the best suggestion yet on what we should do to "pay back" for what they did to on Sept. 11, 2001. We should invest the billions of dollars into products like this hydrogen fuel cell for our cars, and us breaking away from using OIL products/bi-products in our everyday transportation instead of spending billions in bombing a few people.
This way we get rid of the mid eastern funds of doing terrorists attacks and make the U.S. self sufficiant and able to use our own oil for the rest of our needs and not be dependant on other nations for anything.
Invest in the U.S.A. and running them out of their money.
Now then, if you really wanted to get me excited.... you'd be talking about a consumer grade 5 Kw or so Fuel cell that could operate with good efficiency using a high grade of Bio-diesel. Which BTW can be made from virtually any vegetable oil or even oil derived from diatom algae. Of course, you'd have to learn to make your own fuel from the leftover peanut oil that the local burger joint cooked it's fries, in, but fortunately, the book with the recipe for how to do it isn't that hard to obtain...
...Open Source isn't the only answer -- but it's almost always a better value than the alternatives...
Not true! Solar panels are currently nasty silicon things made with all sorts of toxins. That would be OK if they would last forever, but they are generally on the five year plan. Mirror/boiler schemes show more promise, but scraping togeter megawats from 22 watts per square meter is not easy and pilots worry they will be blinded flying over them! Do you want to get into the specifics of making and maintaining the millions of ugly little windmills that are needed to make windpower practical? Multiply your estimates to account for the fact that the wind generally blows when people don't need extra electricity. Do you really want to cut down trees to set up the farms? You did not mention biomass conversion as an indirect solar, but corn was made for eating! Cost = prohibitive on all of these options, so far about 10x the cost of normal generation.
The environmental future is in nuclear. No greenhouse and managable waste all nice and concentrated in a few very large plants. The infrastructure is in place for transmition, so no new scars are needed. The technology is well understood and the safety record is enviable.
Friends don't help friends install M$ junk.
"Solar panels are currently nasty silicon things made with all sorts of toxins. That would be OK if they would last forever, but they are generally on the five year plan."
If you buy a solar panel new from a reputable manufacturer (say, Siemens) it will come with at least a 20 year warranty. That is, they will replace it if it falls 10% below it's rated wattage output any time within 20 years. And they pretty much picked "20" out of the air since they have no idea how long they'll last--all they're sure of is that it'll be more than 20 years.
Furthermore, depending on where you install it (Arizona vs Maine, say) it will produce the same amount of power required to build it in 2-7 years. In other words, however much toxins it puts out, it can clean them up before it's half-dead. A net gain. These are actual working numbers, not theory.
Solar power at ground level approx 1kW/m^2. Market available panels are 15-20% efficient which is 150-200W/m^2, not 22. And laboratory panels have been pumped up to 30% which would be 300W.
I'm not some whacko greenie that thinks nuclear power will kill us all. I'm just somebody that adheres to the KISS principle: the sun is already generating billions of times more power than we could ever use--why not tap into it with a simple collector rather than reinventing the wheel here on earth?
