I didn't know this, I can see how a house appliance might consume several dozens of amps but 100 to 200 amps? Wow, that is a lot. I don't have much knowledge about power transmission (which is one of the most fascinating fields in electrical engineering, in my opinion) so I'll take your word for it.
- rdl 14y agoYou can have a small crappy house/apartment with 40-60A service, for sure. But electric appliances (hot water heaters, clothes dryers, ovens/ranges, etc.) can be 50A. A single excellent commercial electric wok is about 50-100A. Each individual circuit is about 15-20A. The really awesome thing now seems to be HVDC transmission -- eliminates capacitance problems and problems with multiple grids.

Imagine a global grid connecting alternative energy sources for each optimal locale: Geothermal in Iceland, Solar in North Africa, and of course Thorium in Norway. Peter Thiel seems to think this scenario is improbable[1] but I don't think it takes into account ABB's recent breakthrough with HVDC switching[2].
