Reducing the pellet from 25.4 mm to 1.0 mm in diameter, reduces the yield from 14,000 kg TNT equivalent to 854 gram TNT equivalent yield. That's going from 58,000 MJ to 3.5 MJ. This is about 100 milliliters of petrol equivalent. If used in an automobile that uses 9 litres per 100 km, means that 90 pellets are detonated per 100 km. Travelling at 133 km/hr (82 mph)- 120 pellets per hour are detonated per hour or one every 30 seconds.

550 detonations per second producing thrust directly with the high speed exhaust products produces 181 kgf. Mixing inert matter with this high energy flow increases thrust with the same rate of detonation. A rocket belt or air car that has interplanetary range!

And with this source of power, homes will take to the sky, as portrayed in the movie 'Oblivion'
