Admittedly the fuel cell does not provide as much power as the diesel generator, but they are still in the early development stage. The technology curve is still headed up at a pretty steep angle on them.

Heard of Bloom Boxes?

Recently, 60 Minutes did a piece on a fuel cell company in California that has come up with a fuel cell that can power an average American house and will cost approximately $3,000 when they are introduced to the market. Their fuel cells are in use by Google, Ebay, and Fed Ex just to name a few. Their current output is one commercial fuel cell per day and production is expected to increase. The smallest fuel cell displayed in the report was about 4"x4" and can power a European sized home. These fuel cells run on propane and could certainly power an Airstream. At $2,000 or less for one to power an Airstream is less than the cost of solar or even two Honda generators linked together and would provide more electricity.

I saw the same program as Minnie's Mate. I thought the technology was very exciting but wouldn't be available to the general public for 8 to 10 years. I think the companies cited above were in the testing stage. One of the companies,(e-Bay, I think) said they had saved about $400M in energy costs since installing the cells 18 months ago. I hope the cells are perfected and on line soon, as the clock is running on all us mortals. jc

While I am skeptical of the Bloom Box, I would point out the bias the author of this article has against anything other than solar. I wouldn't use this article as any basis for disputing the device.

And yet Another RV FC on Horizon

OK, this one is not available yet as it was delayed to fulfill making cells for the military - which would lead me to believe that there may be some legs to this Company and their product - time will tell.

This unit is a little bulkier, but generates 250W continuously. We can only hope that the industry picks up on FC's (as Jayco is doing) in which case we may soon all be able to purchase a consistent source of off-grid power that delivers regardless of weather or noise restrictions. Link follows:

Protonex Technology Corporation - Recreation - RV Power

Apparently they scrapped the M250 and are supposed to release the propane fueled P125B Q1 2011. They are specifically marketing to RVrs.

I am very curious to see how much this little thing costs.

And another company with a 25W http://www.adaptivematerials.com/por...250w-power-pod

Very interesting. Sure like the propane as a fuel source since we all carry this source at all times. No specialty liquids, etc. to worry about sourcing and transporting. This requires some additional research but certainly appears that it is directed towards the military as well.
