By your logic, if I leave a Sky+ box on standby, then the 20 watts it
spends on spinning the hard disc is converted into 20 watts of heat.

It is.

No. It's converted into quite a lot of 'work', quite a lot of 'motion'
(or what your earthling mind may know as "force"), and a small amount
- much less than 20 watts net worth - of heat.

No. You really don't have a clue. Yes it does useful work but that
work ultimately generates heat (e.g. due to friction in the bearings,
etc.)


If that were true, it would turn Sky+ into a free energy machine -

It's taken 20W from the mains supply. How is that "free"?

You can't take 20 watts, then get 20 watts worth of use (e.g. CPUs,
processors, spinning discs, etc) out of it, then still have 20 watts
left which is magically converted into heat. That's not how it works.
There are losses at every stage of energy conversion.

Of course you can't, and I never said you could. It takes 20W form the
mains and puts out 20W of heat, foing some useful work in the process.
20 in - 20 out = 0. There's no free energu anywhere in the equation.


which is impossible - breaking every scientific law there is.

I think a few laws were broken when they let you loose on society.

Oh, my mistake, I thought this might be a sensible discussion.

So di I until you joined in.

I'll leave you to it...

Good riddance.
