What is more likely is that a Polywell will make the mfg. of liquid fuels on a par with drilling for them.
A jet engine just requires heat, I think - it doesn't care where it gets its heat from, so long as it's compact - could be a liquid salt - like thorium fluoride... But that'll require some hearts to change as well as minds.

Every time I think of Polywell and aircraft at the same time I think of L. Neal Smith's fusion powered derigible the CS(?) San Francisco; a mile long lighter-than-air ship powered by fusion. Passengers lifted by shuttle so it never has to land.katana0182 wrote:Aircraft, well, you never know, possibly good ol' Mr. Fission might be able to help, if it can be made safe.MSimon wrote:At our current level of technology (say the next 100 years) liquid fuels will not be quaint.
