Post by: Vanguard on February 22, 2010, 08:06:12 pm: The article I saw said, ebay saved 100K in 9 months. Annualized savings is 133K. Upfront investment is 4 million dollars for 5 units.

That's 30 years to recoup the investment. Plus, California pays for 20% of the cost since it is a "green" energy. That brings down the payoff to 24 years.

I was impressed until I read this:

Four units have been powering a Google datacenter for 18 months. They use natural gas, but half as much as would be required for a traditional power plant.

Sounds to me like he's got a more efficient generator, not some limitless free energy device.

These are nothing more than fuel cells. Fuel cells have been around for a looooong time. I am writing a grant proposal for my doctoral program based on a SOFC (solid oxide fuel cell). While these have always had great promise there are still a lot of technical hurdles that have to be overcome before we all have these in our homes. One huge problem you run into is contaminants from your fuel streams. Sulfur is a huge problem and deactivates the catalysts typically used in fuel cells. I want this technology to work but i have my doubts.

"California" is so gracious with "it's" money :-\

If they ever made one of these for residential, and it could pay for itself in 5 years or less, I would be all over it. It sucked being out of power for a week.
