Mains power voltage drop to reduce usage?

The plan is to underground all the wiring here. Check back in a hundred years or so.

The standard lot in SF is 24 feet wide. The thermals are good, since only the houses on the ends of the block lose any heat on their long sides.

The garage door is to the right of the pole. We don't really have "driveways" here.

Ugh. So you can hear next door's stereo.

What is the black car parked on?

Well, America and UK both have 240V service in their houses, but American houses have no live wires more than 120V away from ground. Granted, 120V is still dangerous, but it's less dangerous than 240V. So one has to ask, why do you allow such dangerously high voltages in your house?

The rest of the world, however, has verbs.

No. most devices will use the same.

Anything with a thermostat will use the same power, (same energy just spread over a longer period - same average power) Anything with a regulated powersupply will use the same power. The only things that won't are fixed loads like lighting (but they will be dimmer - so users may be encouraged to turn on more lights)

If you turn down the frequency then pumps and elevators will run slower, but there will still be the same amount of fluid needing to be to pumped and the same number of passengers.

With any kind of service it's best to assume that demand will be fixed unless you can get make some of the customers quit, eg. by increasing the price, or rolling outages.

No, we can't.

The loud noises here are mostly from birds. The noisiest are the flocks of wild parrots. And Big Daddy, a raven about the size of a turkey.

Yes, indeed.

In my country house I currently have only one pump, which require three phases. My electric sauna and electric stove are wired for three phases, but could be wired for single phase. In my top floor city apartment I have three phases, currently powering only the electric stove

With 3x25 A main fuses 17 kW and with 3x35A 24 kW.

Isn't it annoying to try to share it equally between the phases?

With up to 50 houses powered by a single transformer, the loads are quite naturally spread between phases.

Because here in .de I have 3 * 240V, 120° apart around GND and my induction stove yields 7.5 KW for each of the front pots. Essential when Gerhard wants spaghettis NOW using 4 liters of cold water. That works even better than gas.

Cheers, Gerhard

It's just parked on the street. The grey one just uphill seems to be blocking the garage, which is probably the house owner himself. It's legal to block your own garage.

San Bruno is a 90-degree parking street. I park there and walk over the footbridge, over I80, to work. Good exercise.

This is an interesting place. A real, dense city that's still part wilderness.

I couldn't stand living in NYC or Boston or LA.

The plugs in the UK are about as big as a cat. They have fuses inside.

Lucky in the sense of being provident. When we upgraded the service about 20 years ago, my husband grounded the hell out of it.

I think we were in that situation at the end of August. The generator didn't sense that it needed to start and half the house was dead. We went out and tripped the main breaker and ran on generator power until the utility came by and fixed it. The central air needed (IIRC) a relay and a fuse replaced, but otherwise came back like a champ. One of our PCs was fried, as were two surge protectors. Could have been much worse. (As a bonus, I got a "new" PC out of it. A used Dell from a local repair/resell shop with an SSD, running Fedora. Much better than my previous jalopy.)

IIRC all domestic heatpumps have resistive heaters, because its necessary to bring DHW up to temp to kill germs.

Very nice. Shame about the socket design.

I find it hard to believe that you don't realise that this is due to the Second Law of Thermodynamics.

What do you do with it, mine bitcoin, you destroyer of the Earth?

I don't know as it does still work as an FF. I'm not too bothered with it as it is.

That can be done with single phase power and a three phase inverter (single phase input, three phase output). I don't know the current price of that, though.

...

In Spain? I'm not aware of any.

Well, there is a shortage of electronics, so the car industry is stalling. But that is not specific of Spain. There are other similar shortages.

Gas? No shortage at all, we have more than we can use. Expensive, yes. But no pipes to send that gas up to Germany, apparently France opposes.

But that was not a "terrible poverty".
