What I actually did mean is there a physical limitation to how small we can get. This first generator FF generator is probably quite a lot too big for for example cars, but can it get that small even in purely theoretical level? Lets say 250kW FF reactor?

Multi-hued Dragon drive? 🙂 Seriously MHD usually means magneto hydrodynamic drive IE. boat motor, I think you mean MPD = Magnetoplasmadynamic drive.

Size: AFAIK, the sizes of DPF devices are constrained by the minimum physics requirements of generating a plasmoid. I’m not sure if it can be made that low-powered.

IOW it depends of how small equipment is capable or producing pinch that is powerful enough to produce practical amount of energy. I don’t think plasmoid itself is constraining factor. That is if I have understood the physics right (which is not at all sure thing).

MHD — well, you’d better let the USAF know it’s misusing the term!

I found out that MHD is used for magneto hydrodynamic systems in systems that include fluid dynamics after posting. “hydro” refers to fluids in general.

The page link above is to the abstract, and it contains a link to the original full report: http://handle.dtic.mil/100.2/ADA446973

Be warned: this downloads a small PDF file without an extension. You’ll have to edit the filename to add “.pdf” to get your software to read it.

Works fine with FF 3.6.12, no need to add “.pdf”. This is what I got: http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA446973&Location=U2&doc=GetTRDoc.pdf
