Can Combustion Engime accept Liquid Nitrogen? Not as fuel but as coolant fluid (like water)
Water usage when temp is above 100°C or 212°F - 1.2 sec per bucket

Liquid Nitrogen (and Liquid Argon) are not good cooling materials for large, hot (room temperature or warmer) objects or machines.

2 reasons:

First, the Liquid Nitrogen turns to a gas on contact with the hot surface. The gas is insulating, so that the cold liquid is no longer in contact with the surface.

Second, the expansion when the liquid transforms into a gas is huge, it can result in an explosion in a confined vessel.

Liquid Nitrogen and Liquid Argon are excellent for cryogenic cooling (cooling things which are already cold) or for cooling small objects - small relative to the liquid volume.

ok, i see

fun fact:
At 20C (~68F) (room temp), 100% RH is equivalent to 17.3 g/m³ of water vapor. 1m³= 35.31467ft³. So, (17.3 g/m³) x (1 / 35.3 m³/ ft³) = 0.49 g/ft³. 3785.4 g = 1 gal, so (0.49 g/ft³) x (1 / 3785.4 gal/g) = 0.0001295 gal/ft³.

So, there is 0.0001295 gal/ft³ of water vapor at room temperature and 100% humidity (fog). So, the equation goes 0.0001295 gal/ft³ x Y = 1 gal => (1 gal) / (0.0001295 gal/ft³) = Y => 7,724 ft³ = Y.

So, you would need to condense about 7,724 cubic feet of fog to get a gallon of water at room temperature.

One of the things so mysterious about the US (for us non-US folk) is how on earth you manage to do science in cubic feet / gallons / etc!

Even here in England, we use metres, litres, kilograms and other metric units when doing science even though we use miles and other imperial units for everyday life like driving, sports, cups of tea, going to the pub ...

We are like NASA in that way :)

1 Minecraft block = 1m³ (which is handy, as it means every Minecraft player has an intuitive understanding of what 1m is). So that's 220 cubic blocks of fog for 1 gallon of water. I'm not sure about the gallons -> buckets conversion ratio, but let's say a bucket is 5 gallons, that's 1100 blocks of fog for 1 bucket of water.

_NERD!_ :-)
It is a bit strange, but we manage. I got into electronics at a very you age, I built a HAM radio receiver and x-miter when I was 10 (Heath Electronics Kit ie radio tubes) so I got into the metric system then, going between them is pretty easy. I also found/discovered The Engineers Handbook and it's got just about any formula you could think of.

I do recall that this did cause a Major QA type short fall/problem/anomaly* with one of the Mars probes. The one team did everything in feet per sec. and the other team did everything in meters per sec, so when the computer went to measure its speed it was expecting one and got the other, and with thrust calculations....

*anomaly is NASA speak for fubar or very very bad

I remember that. NASA specification required that all inputs provided by contractors are in metric units. But the contractor for the thruster firing software used imperial units. Very tragic end for a nice probe :(

Still, bugs happen easily ... as we know here :)
