Just a note on the energy conversions.... Using the numbers given: 200 MEV x 10^15 /sec = 2x10^23 ev/sec. At 1.6x10^-19 joules/ev, this would give about 3.2 x10^4 joules/sec or 32kW.

This would be a fairly small output for all but the smallest vehicles. Most really need > 100 kW to be of any practical use.

Also as has been observed, 10^15 neutrons/sec is about 6 to 9 orders of magnitude above what fusors now can do.
