Mains power voltage drop to reduce usage?

Typically the single phase 230 V input inverter has 127/220 V three phase output. The 230/400 V motors are much more common.

The other alterative is to use 3 capacitors to generate the phases from single phase,, but the output power is severely reduced.

All the easy to get at stuff has long since been depleted. North sea is deep and most of the remaining gas reserves are prohibitively expensive to get at. (although recent price hikes may have changed that)

Output has been declining since the peak in 2000. eg

UK North Sea oil output peaked slightly earlier.

Rough gas storage facility uses some of the empty salt domes.

Good while it lasted but UK gas production and consumption crossed over in 2004 - ever since then we have been a net importer of natural gas. It was fine whilst there was plentiful Russian gas for the mainland but now it is very much a sellers market with insane price spikes possible.

Not having any storage means that we will have to pay whatever it takes to keep the lights on this winter. The campaign to save energy in the UK remains very lacklustre when compared to the 1970's OPEC induced oil crisis which had a very high profile "Save It" campaign slogan.

Ah, yes. That needs a more expensive inverter.

Ugh.

Even if it is a waste, it can be cheaper to use. However, they are very difficult to find here.

Yeah, so what?

The infrastructures are what they are, for whatever reasons. Spain has a huge capacity to take gas, either from Argel or by tanker ships, but basically no interconnecting pipes to the north to send it there. So now we have stored gas enough to last the winter and more.

A pipe is going to be built, to Marseilles, after an agreement between Portugal, Spain, and France. But that will take years to be operational.

I guess he got it wrong. There are city blocks empty because they built a lot of houses that could not be sold when the bubble exploded, not because of poverty.

Some builders had built new villages, that they could not sell. Some are unfinished.

Many people in Spain "store their money in bricks", ie, buy houses as an investment. Obviously when the bubble exploded, they stopped buying.

Then, the people working for the building spree were out of job, and they could no longer pay their mortgage on their expensive homes and lost them. Many had bought bigger and more expensive homes that would be normal, because they were, temporarily, making a lot of money.

Generalized poverty? No way. A crisis, many people broken? yes.

As I said, this is a modern country. Basically the whole of Spain is using smart meters, changed maybe ten years ago. And I saw nothing in media about them being faulty.

Yes, a lot do.

I have one TV on fibre, but the TV on the kitchen or the computer room use aerial.

All good things do not last :-(

Here, there are adverts on TV asking people to adjust their thermostats down to 19°C. This summer a new regulation mandated public buildings to adjust AC no lower than 27°C.

I don't have house heating. I heat a room at a time using a butane stove.

Worked for me. Just shows a charger plug so you did not miss much

2kW 70 quid and it's variable:

Is it possible to use a special transformer to shift the phase? So you take a single phase and lag it a bit? Do that twice over, then you have three phases cheaply.

I have forgotten the math for this, but anyway, it is not cheap. Copper has never been cheap. The cheap method has always been one capacitor, to generate a bit of a phase. Many motors use this trick. Look inside a household fan, for instance.

Or you could buy a cheap car alternator (which is a 1 kW 3 phase generator) and physically power it from a single phase 1kW motor. Noisy though, but if you're using it to poser a three phase motor anyway....

120 degrees phase difference between the the phases. quite a bit more than a "bit".

Since Russia is the source of half the world's gas, when we refuse to buy it, or they won't let us, there isn't enough gas.

They're (form your point of view) pointless, and a possible source of spying and control. Why would you be happy with this? They can turn off your power at will!
