gollark: Amazing what sort of neat technology there is around now.
gollark: I kind of want a watch with an atomic clock so I can avoid having to manually recalibrate the time every month.
gollark: > Ion thrusters in operational use have an input power need of 1–7 kW (1.3–9.4 hp), exhaust velocity 20–50 km/s (45,000–112,000 mph), thrust 25–250 millinewtons (0.090–0.899 ozf) and efficiency 65–80%[3][4] though experimental versions have achieved 100 kilowatts (130 hp), 5 newtons (1.1 lbf).[5]
gollark: I don't think so.
gollark: You can accelerate the ions or whatever to very high velocities, so they're efficient mass-use-wise but have low thrust.
