The main idea is to make a ray of gravitons (or whatever equivalent in other possible extensions of general relativity). For theoretical reasons, the ratio of momentum to energy is fixed at 1/c, which is 3.3E-6 N/kW, that is very low compared to ion thrusters or chemical rockets. Moreover it's the same value that you get with a photon rocket, i.e a laser or a flashlight in the back of your rocket https://en.wikipedia.org/wiki/Photon_rocket So even in space, it is not very useful and you can replace it with a more simple and more efficient device. |
