Both Focus Fusion and Polywell fusion systems are small-- in comparison to big generators.
But that's very much "In comparison."
So is it possible that we may one day get them down to car engine in size, or is that bumping up against solid physics (as opposed to engineering) barriers?
Will we ever get car engined sized fusion power plants?

Does anyone know of a thermal to electrical or mechanical conversion process that is power dense enough for a car? I don't.
BLP's supposed CIHT process supposedly avoids the need for a heat conversion, so this system could be used for small motive applications like autos and small spacecraft, but other than that I don't see one for fusion.

In a dense plasma focus device, fusions take place within tiny plasmoids, perhaps leaving hope the process that generates plasmoids can be scaled down enormously - even to a silicon chip level. in 2001 Casio claimed to be working on chip-scaled "reformers" (high heated reactions to liberate hygdrogen for a fuel cell). That's hardly fusion, of course, but it illustrates how small some industrial processes can become.

A 4 piston swash-plate Stirling cycle engine has been demonstrated for auto applications. IIRC it has been heated both by a liquid fuel burner and a molten salt heat source.GIThruster wrote:Does anyone know of a thermal to electrical or mechanical conversion process that is power dense enough for a car?

Seems too much tech to put bother putting on a car, unless you are building a time machine or something?
Big fusion power plant nearby making hydrogen for you from water that you buy from the local service station just like gasoline sounds good to me. Or just use batteries, if that technology improves an order of magnitude.
Hmm...on second thought, a fusion powered rover for long term manned Mars mission might be apropos.
Of course, in the off chance if what Rossi claims to have is real, that might be small enough to power a steam engine car. Nice...

Why not fusion generated electricity within a semi-conductor?
There may well be answers to that question (something about scaling laws, perhaps?), but it's fun to think about.
