What are the two things that get their current from generator?

Kinetic Generating Plants

Hydro-electric plants and wind-mills also convert energy into electricity. Instead of heat energy, they use kinetic energy, or the energy of motion. Moving wind or water (sometimes referred to as "white coal") spins a turbine, which in turn spins the rotor of a generator?

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask
