#2 Color me skeptical. If they don't have demonstration models now, they won't be shipping anything in five years. And if they ever do have an actual product the cost will be more like $250MM/unit after litigation related expense.

#3 I'll believe it when I see it. The numbers sound more like wild promotional marketing than engineering numbers, and there are a whole lot of unanswered questions like where does the waste heat go and who pays for the fuel reprocessing and disposal.

"Probably means a kw/hour"
No, I think they do mean 10 cents a watt. $250 per home would allow each home 2,500 watts. Not enough for my modest home, but it may be enough in parts of the UK.

#4 I had to dig around on the Hyperion web site, but eventually I found it in a press release:
"Each unit produces 70 MWt, or 27 MWe when connected to a steam turbine - enough to provide electricity for 20,000 average American-size homes or the industrial equivalent."

So the price they're touting is just a heat source: steam turbines, condensers, generators, etc. are not included.

Don't get too excited.

#5 The wife and I were flying out to the left coast to visit the daughter in October. I picked up the October 2008 issue of Discovery and was thumbing through it. The following excerpt caught my attention:

"...an obscure piece of technology known as the vanadium redox flow battery. This unusual battery was invented more than 20 years ago by Maria Skyllas-Kazacos, a tenacious professor of electro chemistry at the University of New South Wales in Sydney, Australia. The vanadium battery has a marvelous advantage over lithium-ion and most other types of batteries. It can absorb and release huge amounts of electricity at the drop of a hat and do so over and over, making it ideal for smoothing out the flow from wind turbines and solar cells.

#6 Excellent, wonder if she has a patent on that reflux-battery, if not why not?
