A steam turbine is (to some approximation) an inverse heat pump. You can use the temperature delta from an electric heat pump to run a turbine and generate electricity, but the laws of thermodynamics guarantee that the power output of the

No, because 1 kW of heat would produce much less than 1 kW of electricity.

If you fill to the minimum line (0.5L) instead of the maximum (1.7L), it will boil in under 1 minute. When buying a kettle, the most important specs are the minimum fill and wattage (ideally 1500W in the US.)
