   Spacecraft with rtg for electricity generation that uses the ir radiation it needs to vent as propulsion

     @snacks the pioneer anomaly was exactly that and the acceleration on that was 8*10^-10 m/s^2

     @chjara til. As for acceleration, just wait™, you can prob get more acceleration by purposefully only venting in one direction too

     @snacks like light recoil propulsion is absolutely possible but there's a reason the serious concepts are more like expanding 1 km^2 of foil near a star

     @chjara thought it was mostly by radiation pressure, sad

     @snacks no, orion works by using a nuke to vaporize a bunch of mass away from the spacecraft so it's propelled by the reaction force, just like a regular rocket engine but with nukes

     @chjara @snacks hey light sail works and is cool
     
     but its not really fit for interstellar flight and also good luck sailing back ig
     
     there was also some silly thing where you accelerated it by firing laser into it from earth
