No, not a potatoe chip.

Very cool.

Sounds exciting but if you read the fine print they don't even have a
working prototype as yet. Many questions too. Fuel used, starting
combustion, getting rid of the heat and so on? The 10 watts (on paper)
goal is pretty cool but they're touting it as a lithium-polymer type
computer battery replacement. Also, what about the noise of a
1,200,000-RPM "combusting" gas turbine, "the size of a quarter"?

Scientific spin-doctors need to get a bit further along before making
such exorbitant claims.

Hmm, I thought the article discussed heat dissapation.

But nano technology is here. Besides this is an Army funded project. Our
tax dollars at work.

The noise, hopefully is as sweet as the start grid at a MotoGP race?

I wouldn't mind hearing it. I often listen closely to the microdrive in
an embedded computer spin up just to hear something so small do so much.

I still don't know how they are going to manage a tiny heat chamber to
power a set of compressors. How thin is the insulation going to be?
There's going to be lots of heat lost per second, so the burn to energy
scavenging conversion must be very quick! That's why I don't think we'll
ever see one work. Its like trying to light a flame smaller than the
period at this sentence. Too much outside heat loss to sustain a local
chemical reaction.

Of all the articles I've seen on this, I've never once seen how they are
going to keep the heat inside. Its like a nuclear reactor that loses all
its neutrons the first billionth of a second.
