We heat our kettle with gas. All that heat winds up in the house,
which usually needs it. An open flame is a more efficient heater than
a gas furnace; no heat is vented.
Even resistive heating is better than a furnace. Except for gas being
cheaper for some reason.
I find it hard to believe that you don\'t realise that this is due to the
Second Law of Thermodynamics.
I know why it happens, just not why people use a furnace with gas. It\'s
a waste.
The highest efficiency gas fired power station is aroung 62% efficient.
Then there are 5% transmission losses.
A condensing gas boiler is over 90% efficient.
Then why don\'t they make the power station like the boiler?
the power station makes electricity not heat....
Is the heat to electricity section that inefficient?!
Yes, you can blame Mr Carnot for that.
For best mechanical (and electric) efficiency, you should have as much
temperature _difference_ between the hot and cold side (measured in
Kelvins) as possible.You should maximize the hot side temperature and
minimize the cold side temperature.
In a coal fired power station, you can have hit side temperatures over
550 C, but current nuclear plants only tolerate about
300 C.
Not exactly true...depending on what you mean by \'current\'
Look at \'Natrium\' where the reactor is to be cooled by molten salt,In <iv65nhtrqc39c4s2g4tejt2vkehgs4gm64@4ax.com> upsidedown@downunder.com writes:

Those of us with long memories and who lived in the NYC area
recall the original Indian Point nuclear power plant
(they later added #2 and #3) had a fossil fueled
additional boiler to yes, raise the temperature
of the steam even hgher...
Excellent plan!On Sat, 12 Nov 2022 14:58:57 -0000, \"Commander Kinsey\"

Waste of what? If you heat with electricity heat is wasted in the
cooling towers of the power station .
and in transmission lines.
Power stations should be closer to houses.
If you have an unused swimming pool in the basement of your apartment
building, just throw in a small research reactor (100 kW to 1 MW) and
you have heating for the winter
It sounds like what he saw was a spent fuel pond.On 2022-11-12 22:48, Bob F wrote:

I visited a swimming pool reactor on a field trip while in high
school. It was really something to stand on the side of this deep pool
of very clear water and see the glowing elements at the bottom, know
what it was causing the glow.
I\'m curious.
Do they have to add chemicals to the water, to keep it clear, no algae
or bacteria? Or simply the radiation keeps it \"clean\"?
So obvious that in 200 years of steam engines no one has thought of it

The blue glow is Cherenkov radiation.
You can swim, but don\'t dive deep.
I don\'t think any bugs would survive it.
