Nope, run pipe up the back and use the hot water to run sterling cycle

Depends on its design.

The UK designed the 'fluidised bed' generator which even today is the best
classic fossil fuel generator.

Flue desulphurisation can remit bad effects on plants. Increased CO2 increases

plant fertility and crop results.

Atmospheric CO2 levels are a sideshow. They have no effect on global warming
or cooling, and we're cooling now. Haven't you noticed ?

While it's probably true that all manufactured artifacts are front
loaded with /some/ kind of energy consumption, I think the source(s) of
that energy are increasingly a matter of choice.

As regards the point at which devices reach the energy payback point, I
think you may be painting with a too-broad brush.

Agreed. I'd like to see the energy impact analysis for this, but this method
seems to have been dropped by the greens when they reckon they have something
that's 'so good to be true'. How about some science to see if it is or not ?



I believe they were factually correct taking into account all circumstances.

That's a point I try to get across.  The ethanol debacle is a case in
point where you hardly get more fuel value from the ethanol than the
energy required to produce it.  Add unanticipated increase in food
prices and you have a greenie legislated mess.  These things are forced
on us by those without technical backgrounds or fundamental engineering
knowledge.

I read somewhere recently that a new solar electric investment would
have a payback period of 6 years and that's with 50% government subsidy
but about 2 years ago a full story on a documented installation by local
paper said 30 years even with subsidy.  This is way past my age/life
expectancy. Plus my house is over 30 years old and every single major
appliance has had to be replaced including furnace and central air.
