What's important is the total energy produced by the engine AND the fuel supply. It doesn't get the least bit interesting until the engine can lift itself and a FULL tank of whatever powers it AND the vehicle AND the payload to reach the destination. I can't imagine that ever happening 1000 feet off the ground on this ole earth at a cost anywhere near the cost of other forms of transportation. Stick it in space where you have solar or nuclear energy and you don't care how long it takes to get there or what it costs and you have something.
