comment Exhaust liquefaction in internal combustion engines
But would it theoretically be possible to liquify the entire exhaust? The container would have to be quite cool I guess.

comment Ocean surface mean current flow meaning
In fact binning the data by weeks instead of month and switching the data according to time remedies the effect. So I guess averaging the flows doesn't predict the actuall motion well which is highly non-linear.

comment Sound in stirred hot fluids
I will try this with water only, but there may still be air bubbles inside. How to get an gas free hot fluid at home?

Two plausible explanations so far.

comment Sound in stirred hot fluids
The sound of the cup depends on it's shape but also it's stiftness, so an irregulary heating the cup (hot inside, could on the outside) could change the material stress by magnitudes (lower or raise) and thus the tone. The stirring adds more of this heat to the cup as the cup surface layer of the fluid gradually cools down with the cup. Sounds quite plausible.

The spoon actually stays in the fluid, so it doesn't change temperature that much. The experiment can be repeated again and again without cooling the spoon.

comment Biological heat dissipation methods
Summarized, if ground, air, and cloud cover have 38 degree and humidity is 100%, one will die.

comment Biological heat dissipation methods
If I get it right, all methods mentioned despite sweating require some matter that is colder than the body. For heat transfer to air, it has to be colder. For transfer by radiation, the visible environment has to be colder. This is actually the most likely one I consider, as with a clear sky, the environment partially consist of deep space, which is extremely cold, and the sun, which is extremely hot, but it's radiation is almost parallel and can be blocked easily. However, with humidities about 100% the sky would be more likely occluded. It would have a high temperature then too.

comment Gravity effect on moving bodies
So we can expect the change of gravity forces in one position depend on the change of their sources in a wave propagating manner, but the effect itself in one place is not affected by the speed of movement of a body in this field? So if I suddenly move the sun more far away from earth, earth would feel the change with about 8min delay. But if I move earth a bit, it would feel the change suddenly I guess. This insymmetry depends on the observer, once more, I guess, like if it is fixed to earth or sun.

comment Ocean surface mean current flow meaning
I don't think so, as there a hundreds of attractors each hundreds of kilometres in diameter. Filtering them out would result in a very rough picture that maybe would not be natural anymore. My guess is, that those attractors themselfes will move by a current on a larger scale on larger timescales. So the monthly mean may show attractors that would not exist on some-year time scales. Particles that would seem trapped by an attractor in a monthly mean may travel with it so they move in larger patterns over the years may hit a coast eventually.

comment Location of heat conversion in heat engines
But the equalized temperature would be lower, if compared to a system where there is no piston, and the temperature just equals out by itself?
