Finally had some time and went out to their web site and looked a bit on the web, a couple of observations....

1. This thing is huge and expensive, it won't be mobile (20,000 pounds for 100kw). We used to price things by the pound, and that still holds true today. Bigger heavier stuff usually costs more. The performance isn't all that great (50% conversion efficiency) and in fact the DOE has awarded a contract to produce similar energy efficiency from conventional means (rankine bottoming cycle on a small turbine) that is within today's technology and won't cost over $500/kw in first cost, so that's a bogey where they have to be.

2. While we are talking about first cost, the first cost now is $7000/kw. That is crazy expensive, somewhere between 15 and 20 times where they are going to need to be to be successful. Not necessarily impossible, but it is going to take automotive production quantities (tens if not hundreds of thousands of units per year) to do it, and I'm not sure that those kind of quantities are in the cards.

3. The "coming out party" was full of hype, a lot of sizzle and not much steak. The bit with the unvieling of the box of sand was particularly trite. I'm not the only one who thinks they are priming the pump for an IPO...

It will be interesting to see what comes from this.

The cost of getting an adequate natural gas supply to someone's house to power this fuel cell would be about $35,000 not to mention the gas distribution system would have to grow to massive proportions if this became a reality.

This is no different then the "Cold Fusion" hype 10 years ago.

This may be true in the warmer climates, but a majority of people, at least in my area, have natural gas in their homes.

As to the cost of getting the gas to a home, please direct us toward your source. I know the government is extremely inefficient, but that seems very high.

Umm, sorry, the Bloom fuel cell is nothing like cold fusion. For one thing it works. Sure they over-hyped it but the technology is real. Whether they can mass produce them or get a basement sized unit in at a price the average consumer can pay is still an open question.

I just had gas piped to a house in Fort Lauderdale for free. The gas company tapped into the main and ran the branch to the house.

Try these guys at ACTA, they seem to be at their best with small cells.

Plastimo are also doing a fuel cell gennie but fuelling it is going to be a problem due to shipping volatile fluids.
