Q. Radiation pressure imputes constant acceleration on a receiver under constant energy input, but its E=0.5*m*v^2. How is energy conserved?
@TobiasBerghoff @Reedbeta Ah, energy loss of the radiation field via redshift, thanks! P.S. Another reactionless thruster design thwarted.

@TimSweeneyEpic@TobiasBerghoff@Reedbeta not sure about redshift, photons momentum is transferred to the accelerating object. -
@marcosalvi@TimSweeneyEpic@Reedbeta Huygens makes the reflected photon subject to Doppler, no? - 6 more replies

@TimSweeneyEpic@Reedbeta Well, best of luck. :) -
@TobiasBerghoff@TimSweeneyEpic@Reedbeta energy is conserved only for the whole system: (sum_i photon_freq_i*planck_constant) + 0.5*m*v^2 - 2 more replies
