20 Kilowatt hours to produce one carat of synthetic diamond
1 carat is 0.2 grams
100 kilowatthours per gram
100 watthours per milligram
One millimeter of water would be one millionth of a liter.
Diamond is 3.52 grams per cubic centimeter
one millimeter diamond 3.52 milligrams per cubic millimeter
352 watthours per one millimeter diamond
one watt hour is 3600 joules
1.267 megajoules to synthesize millimeter diamond bullet

a millimeter diamond bullet with the kinetic energy of 1 » 2 MJ, or at the speed of about 1000 km/s, is su±- cient to initiate a propagating thermal nuclear burn
The neutron energy is ignored in our simulation, but it does help in heating the electrons globally. With simulation obtained shell density and width, about 5% of the 14.1 MeV neutrons will scatter with the ions, and leave approximated one half of their energy to DT ions. The 6 » 7 MeV D or T ions can travel more than 10 times further than 3.5 MeV alpha particles. They can penetrate through the density shell
The peak energy from an impact is 4 petawatts but mostly at 1.5 petawatts over about 40-50 nanoseconds. 80% of the energy is wasted.
lets say 2 petawatts for 40 nanoseconds
2 million gigawatts for 40 nanoseconds
80 million joules
16 million joules not wasted
3.3 megajoules to produce the millimeter diamond and accelerate it
16 megajoules generated
net 12.7 megajoules per shot.
