So what if it does?’
My point was, that if you are still permitted to pour water from the kettle, in spite of the fact that doing so will cause the lesser amount of water in the kettle to heat up even more (because there is now less water but the same amount of heat on the blech), how would that concept be any different from causing more electrical power usage by additional weight in the elevator (though in the opposite way, being that in the case of the water, the lesser weight/volume causes increased energy, and in the case of the elevator, ADDED weight causes increased power usage – still a shift in weight causes power consumption to increase in both cases)?
