9 days agoNowadays people use radical in political terms as another word for extremist, but it used to mean going to the root causes. Equality and justice, or the lack of, are the root of many political issues. So you are radical in a way, but that is good.
Yes, but that would be a lot less efficient. With a dielectric mirror you can get easily 99.9% of the maximum momentum gain from the light, while with a solar powered laser you would get for the emission the compounded efficiency of the solar panel + storage + laser, so way below 10%. So you would gain around 10 times more impulse from your solar panel absorbing light than from the actual laser.
The final momentum gain is a bit different as the maximum you can gain from a photon is double its momentum (because you can reflect it back with opposite direction).
