At night, deserts can be mighty cold. This is surprising to
many since they're often mighty hot in the day. This
happens because while facing away from the sun, thermal
radiation emits into the cold abyss of space. Deserts are
rarely covered with cloud, so the radiative process is
Deserts are usually low in water, which is right up there as
a thermal buffer, particularly when it comes to changing
states from solid to liquid to gas. Deserts also famously
lack outdoor ice skating facilities, which makes Canadians
sad, and has detrimental effects on the development of
grass-roots curling teams in rural Nevada.
To solve the pressing global issues of sad Canadians and
curling facility supply, I recommend the construction of
enormous Ice rinks in the deserts of the world.
Following the construction of large shallow pools,
enormous compressors work throughout the night* to
freeze the pools solid. This process removes tremendous
heat energy from the water and radiates it into space since
the refrigeration equipment features space-aimed
Come sunrise, happy Canadians may skate between
nascent curling teams on fresh level ice. By early
afternoon, however, the ice will become unskatable,
mostly melted from a hard day's heat absorption.
Overnight, we repeat the process, beaming ever more heat
into space solving all the important problems. I should also
insist that the parabolic emitters be steerable. Once a few
hundred GigaWatts of emitters are installed, we could
focus all the thermal energy at will, like a big
environmental Death star. This would be useful should the
Borg turn up. Granted it relies on them staying on the night
side of the planet, but their waxy pale pallor is clear
evidence that this will be the case.

||You'll get more ice for your dollar by rolling over the ocean* a giant white tarp in the daytime.
||*choose a patch you don't care about much
||Maybe make it mandatory that all plastic produced
will be white or silver, so when it lands in the ocean it
will increase our albedo a bit.
||Sorry, can't help your libido though...
||yup, the world needs more skating rinks in hot deserts.
||Another way to skate in the desert would be to use daytime light energy to fuse sands which can then be polished to a highly, ball bearing, slippery surface.
||What we ought to do is to find all the bald people in the
world, and offer them a few dollars per hour to stand
outdoors on tarmac when it's sunny.
||Could we set this up on Venus and aim it at Mars?
||The question being, can shape be hot or cold? Can different shapes be constructed, at the correct scale, to help cooling processes?
