Intake Valve and Feliks' ideas

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

Friction in the rollers, friction in the belt (bending and straightening around the rollers), radiative heat loss from the warm buckets, convective losses from the warm buckets, conductive and radiative heating of the cold buckets, conductive and radiative heating of the "cold air", convective currents in the surrounding air (caused by the movement of
the system through the air). There are so many losses in the machine that it's obvious that it can't work as advertised

Andrew :D
The pipe in your drawing contains hot air which is lighter than the atmosphere. Normal atmospheric pressure at a height of 500m is (rho x G x h) ie 1.2 x 9.8 x 500 = 5,880 Pa less than the pressure at the bottom. Inside the pipe, the air is lighter and the difference in pressure (top to bottom) is 1.0 x 9.8 x 500 = 4,800 Pa. The difference is 1,080 Pa so the hot air is trying to rise with a driving pressure of 1080 Pa.

The fan needs to overcome this much pressure to move the hot column of air down and the power of the fan is flow rate x pressure = (2,800 x 12/100)m^3/s x 1080 Pa = 362,880 W = 363 kW = 483 hp - the same as the power generated by the rising buckets. (Your original calculation was pessimistic)

Did you calculate ?
After all, this is not a perpetual motion device, so some losses must be ...

A hot air balloon will also fall down on its own, if we don't heat it up a bit ...
But generally you like my engine? =D>

Well, I see that I need to do the mathematical calculations step by step ...
so we have a 14m x 20m x 10m = 2800m ^ 3 bucklet ... he gives STRING at these 80 degrees Celsius those 500 KG of strength ... in a line, ALL bucklets give a total thrust of 12 x 500 KG = 6000 KG .
Now the pulling wheels have a diameter of 20 meters, i.e. a radius of 10 meters .. So we get a torque of 6000 x 10 m = 60,000 Kgm.
The circulation time of 1 bouquet is 100 seconds on this road 500 meters. or 500 meters divided by the circumference of the wheel, i.e. PI x D, 3, 14 x 20 m = 62 m, i.e. 500m / 62m = 8 turns, to overcome this path ... So one turn, that is 100 seconds / 8 = 12, 4 seconds lasts, i.e. 60 / 12.4 = 4.83 RPM per minute, on the wheel shaft,
The power we get with such parameters is 4, 63 rev / min x 60,000 kgm = 335 HP.

But now we can build it in a shaft dug in the ground, every 1000 meters deep, which is not a problem, and still part above the ground ..
And of course further permutations ..

Well, the usual waste would be the release of hot air into the atmosphere ...

Let the warm air go. Just let it go.
It wants to go up. Let it go up. You will spend more energy bringing it back to earth. In fact this air will be colder than the ground air. Making brining it back even more a waste.

Ok. The weight of chains/belt... will cause a large amount of friction on the pully at the top.
Call it "drive train" losses. I suggest a simpler device with less points of friction.

Like a fan, for example.
Then, turn the fan sideways, and put it in the wind, now you don't need the heat source, magic!

& what of rigging up an equivalent sea-based system, with a bucket/balloon tower
seated adjacent to a volcanic 'hot smoker' column, with hydrodynamic effects?

The 'smokers' are easily hot enough to drive generators with steam as they are at high pressure ( if piped to the surface or automated on seafloor).
There has been talk of setting up factory units around them in future as the 'smoke' is rich in all sorts of minerals that would filter or condense out and could be a supply of pure water.

This is a long way of yet though
