Seeing if you can think. Seems not.
Bye.
This is obvious:
Start status:
Hot gasses flow: 200°C -->-->-->-->-->-->-->-->
<--<--<--<--<--<--<--<-- cold water flow 15°CStable status:
Hot gasses: 200°C -->-->-->-->-->-->-->--> cold gases at almost 15°C Hot water at <--<--<--<--<--<--<--<-- cold water 15°C nearly 200°C
But the output gases can not get colder than 15°C in that example, without a heat pump.
*shrug* I don't need you to validate my engineering credentials.
And curiously, if you put in a heat pump, the heat pump will use more energy than the extra energy you will get out of your steam engine.
Which is why not one persons in over 200 years of steam engine design, has ever bothered to do it.
You can get much better from a cooling tower where the latent heat of evaporation pulls a few more degrees out of the typically 45 degree turbine exhaust temperature.
They didn't need a heat pump, as the superheaters (driven by flue gasses) were sufficient for their purposes.

The steam turbines on big ships had superheaters, preheaters, economizers, geared HP and LP turbines, steam powered electric generators, steam powered feedwater pumps, distillers, and domestic water heaters. And enormous sea-water condensers. They didn't waste any heat.
But the plants were so complex that owners couldn't find the crews to keep them running. They had a chemical lab for the feedwater.
Direct-drive reversing diesels are so much simpler.
WTF? Why do they need your readings that often?!
There was never any need for smart meters. What a waste (economically and environmentally) making all that new equipment.
Please don't tell me you're one of those stupid tactical voters. If every small party voter says "not enough people would do", then they themselves are creating that situation!
Nobody NEEDS to keep warm, it's just nice.

at the graphs on the right, and scroll down to see more. Nothing even goes below zero!
Does your E.R. stand for emergency room?
But the rechargeables last 10 years.
Ah, I'm not familiar with LR44. Only the AAA/AA/C/D series, PP3, and the CR series. Clocks (at least the proper ones with moving hands) are usually AA.
Was it as heavy as my Fed 4?

that's a solar panel for the manual light meter, no batteries required. You then adjusted some dials to match the light meter pointer with a sensible aperture and shutter speed, then made an adjustment for the slightly busted solar cell from dropping it earlier. Then realised the subject had wandered off.
Obviously the people that held the purses did not think like you, thus you are mistaken.
At a lower voltage: 1.2 vs 1.5. That's enough to make the LCD readout of a clock nearly unreadable, too dim. On some devices, it triggers the low battery warning.
I know, I use rechargeables.
Can't you take to the streets and yell like the French?
What an absurd place to choose to live.
If you do not see it then it isn't very big.
Then they must have had a poor sense of smell. I smelt mine when I didn't do up a connection very well under the floor.
Both, well never mind.
Well I've managed to never remain in a dangerous position.
Just read reviews. Alkaline is alkaline. NiMH and LiIon, shoddy workmanship galore - Panasonic 100% of what it says on the tin. Samsung 80%. Any Chinese s*it like Trustfire or anything with the word fire in it, 20%. I've tested all these by charging and discharging through a torch. Best to weigh the battery, when you get ripped off, they're much lighter!
The clock is bad when it fails to keep time.
I guess what we need is something better than a thermal engine.
That's not why they made them. It's environmental bullshit to encourage us to use less power. How ridiculous, we use what we want or need to, until the bill is too high, then we use less. Seeing it in realtime is pointless.
I haven't seen a device that can't handle the lower voltage for about 15 years. And that was a mechanical clock. F****ng terrible on any kind of battery, as it slowed down as the voltage changed.
