It is funny BUT it takes a lot of hear to completely vaporizer a liquid but once in a vapor form it takes a lot of cold to condense it back into a liquid..so there is some room...
The idea is to bring it down to a safe temp where it is not likely to flash burn, like the vapors that comes off say a cup of gasoline...it does not burn without something to start it.
2) What is it about a vapor-powered engine that would make it run cooler? Is it that the vapor supports a much leaner condition so there's less actual combustion going on? You'd mentioned that toward the beginning of the thread and I've been wondering since.

The story is that IF you use pure vapor and at the right amount it is all burned in the early power cycle and there is no extra to burn as in the normal combustion where there is burning gas all the way to the catalytic convertor which then burns almost all the left over...so there is no burning gases for the rest of the power stroke, nor the exhaust stroke, nor as it leaves though the exhaust valve and as it goes though the exhaust manifold and into the exhaust pipes..
It is said 70% of the wasted heat the cooling system has to handle is from all that wasted burning fuel.
