TerryLennox posted:I am aware we are running two ACs at night (non-inverters) but what worries me is the climb in our bill. We have 3 PCs running intermittently (they go to sleep mode when we are not using them) but most of the day, there is no one home to use that much power. Recently my brother has come to live with us and as a pilot, his work schedule is kind of irregular and he is a heavy sleeper so my AC is probably being used 12 hours a day. Is that the only cause of the power increase? Is there a way to calculate our power usage? A smallish portable AC unit (maybe 1 ton or less) is using 5-10x as much electricity while operating as a computer. AC is by far the biggest user of power in homes that have it, and the moderate increase in usage is where the extra is coming from.

Cheesemaster200 posted:Speaking of arc furnaces: I spent a few months working in the same campus as one of north america's larger high power test labs. Supposedly they were capable of putting up to 10% of British Columbia's power output through the DUT, although they generally didn't since as I recall they didn't have a generator-motor style isolation setup and so maxing it out could cause blips as far as california.

Doesn't hydrogen gas have a tendency to be absorbed into metals and make them brittle? Or is that only at very high pressures?
