Mains power voltage drop to reduce usage?

There must be some kind of heat exchanger system they could use. Or another use for the warm gases. Heat the neighbouring village with steam or water?

And you trust the justice system? Let's say you and your neighbour have a dispute over something. Your neighbour sneaks over to your house in the middle of the night and does something to your meter which acts in your favour (or in the case of a smart meter he could do it remotely). The electricity board and the court will probably say you're stealing electricity. At least with the old meters you could have a security camera.

Not in the UK.

With a heat pump, they can. Imagine a boost converter.

If... if... if... all your ranting is useless and pointless here. Here, you either have a smart meter, or no electricity. You can get mad at them all you want. Argue all you want. Pointless, it is done and forgotten.

I do not live in the UK.

Not free here, and sometimes you do not see it.

Sometimes. Some thought like you, now they are dead.

But not you :-P

To know if that battery is better than others, or to know if the clock is going bad. And because I like to do it.

Guess why this is not massively used.

Well, this is already done.

Have a thermal engine generator generate electricity, and use the exhaust gases to heat the area.

Oh dear.

I think John is mentally ill.

Not exactly true...depending on what you mean by 'current'

Not many coal are much different from nukes - all about 37% at full load

With nukes you can of course do better - gas or sodium cooled can go way hotter, but why bother? advanced tech is expensive, uranium is dirt cheap.

Look at 'Natrium' where the reactor is to be cooled by molten salt, which is stored in a heatbank to help the reactor respond to peak demands. Add more water, instant increase in steam

I think you are an amateur flamer who doesn't want to, probably can't, intelligently discuss electronics or thermals. Your prime motivation is to be nasty.

Imagine a boost converter.

Imagine a water heater that has exhaust flue gas temp of 100c and heats water to 200c. Try.

Actually, it doesn't even need a heat pump.

I'd need a charger for them*. And I only use them in low consumption devices like clocks. I've got rechargeable AAs and AAAs and a charger for them, but I don't use them in things like remote controls as the batteries last a year or more.

• I used to have a charger that charged a single NiCad button cell. It consisted of a resistor and a diode.

The cell fitted a Russian MW/LW personal radio that was 1"x3/4"x1/4"**. It used a thin-film integrated circuit with discreet transistors &c.

With a counter-flow heat exchanger, flue gasses could easily be colder than the hot water output.

Yes, that's one obvious way.

So obvious that in 200 years of steam engines no one has thought of it Wow! F****ng Genius!

I used to design control systems for steamships. Water temp was maybe

So I'm not mentally ill after all. What a relief.

There are lots of other examples of water hotter than flue gas. Your turn.

What are you dribbling on about?
