Night storage heaters

[JohnW2]

I have a feeling that the heat would be coming from the voice coil. After all - if it's in a soundproof box there'll be nobody to hear it, so it won't produce any sound.

Are you serious? Yes, I'm sure that a little heat would come directly from the voice coil, but that would just be the 'wasted' energy as far as the speaker were concerned. Most of the electrical energy supplied to the speaker would presumably be converted to sound energy, and that would have to 'go somewhere', even if no-one were in the box to hear it Is it really materially different from a lamp in a lightproof box - again, there would be no-one in there to see the light, but it would still heat up the box.

Kind Regards, John

And going back to storage heaters

Yes? I think that the very first response you go more-or-less 'said it all'. What else would you like to know?

Kind Regards, John

There were some estimates made in the 1980s that gas would only last for another 50 years or so - these proved to be grossly incorrect, as since then a lot more gas has been discovered and technology to extract it has improved significantly.

When the 'great conversion' (from town/coal to natural gas) occurred in the early 70s, the estimate for North Sea gas was only about 30 years - which led some to question whether the enormous cost of the conversion exercise was justified.

Kind Regards, John

Are you serious?

Not entirely.

Was George Berkeley?

Then why don't you stop posting drivel?

Better to remain silent and be thought a fool than to speak out and remove all doubt.

Abraham Lincoln

But it is not drivel. You still have not answered the question what happens to the sound energy once it is absorbed by your body?

It gets stored in acoustic delay lines and then released later when nobody is listening.

Yes, they are 100% efficient, so once electricity is put in them you don't need to put in any more.

I'm selling my SSE shares, electricity prices will tumble.

What a silly comment. You have no idea what efficiency is. I suggest you say no more.

We've suggested you say no more loads of times, but it seems to have had little effect
