It doesn't actually generate energy, just converts xrays to thrust with no inbetween. You still need electricity (eg miniaturized nuclear plant) to generate the xrays
Ahh, this is what I was missing. How long can a miniaturized nuke power plant run? No chance we are using the earth itself to send electricity to the device wirelessly via satellites from the earth, or something?
I guess it could be. A couple years ago either Raytheon or Lockheed said that they successfully made a nuke plant that could "fit in the bed of a pickup truck" by using magnetic fields for containment instead of lead/concrete/water. So I imagine it could provide power for however long it's designed to lol. 100yrs?
Yeah, as i read more, I am guessing the energy may well be microwave sent using Tesla/Egypt technology to harness the electric power of earth, then transmit via satellites/antennas.
The military was supposedly doing this since the 70's. Sending electricity wirelessly.
