Re:Just a little prob with the numbers....
I remembered reading about this Stirling powered sub sometime back: http://www.kockums.se/Submarines/aipstirling.html

Re:Stirling Engine Is Not Magic
Stirlings don't have to be used for low power systems, it's just that they tend to be used in a "energy from the environment" mode as a type of free energy.

Re:Stirling enginesThe nice folks at Kockums (a division of ThyssenKrupp Marine Systems in Sweden) set up this web page in English with a cutaway view and diagram:

Re:Superceded - reality check
And the australian Collins-type submarines were built by Kockums Marine Systems in Sweden; those Stirling AIP engines are quiet as well as being able to allow the submarine to stay submerged several weeks. Interesting that Sweden possess such a prominent position in the submarine market (scroll down towards the end).

Who was first, the chicken or the egg?They never had a stealth ship since the mid-80's...
The Sea Shadow program was begun in the mid-1980s...
The Swedish project was initiated in 1986:In 1986 the Swedish Defence Material Administration (FMV) initiated the development of a stealth test platform, HMS Smyge.

Another cool vessel
The swedish Visby class corvette is another neat piece of work, though one has to argue that taxpayers money could be better spent.

Norwegian Navy is getting stealthy boats
Check here for more info (in norwegian only, sorry) on the Skjold-class MTBs. I'm not sure when they will be ready though. The boats are propelled by water jets which means they can turn really really fast. The swedish navy is also getting stealthy boats, and they got water jets too.

Sounds like the Swedish "Visby" corvette...

the Swedish Navy
We've got Air Independent Propulsion on some of our subs in the Swedish Navy... (well, as some of you would point out, it's only independent for a period of time.) The trick is to use liquid O2 and a diesel burner to drive a Stirling engine, and use enough pressure during combustion to be able to feed the exhaust out into the water. Since it's mostly CO2 it dissolves quickly. For the burner to get "air-like" oxidizer the O2 is mixed with a small back feed of reused exhaust. There is a more thorough explanation on Kockums website.
This is not as clean as the drone in the original article, but OTOH, the collected exhaust in the drone has to be disposed of somewhere - it's not gonna disappear just because it's not in the atmosphere.
