Would the droplet cooling system from Mass Effect be actually possible in our universe? I'm interested in expanding the space industry and promote manufacturing in space. One of the biggest problems that seem to persist is heat dissipation, radiators are ok but there has to be a better alternative. I was thinking of the droplet cooling system from Mass Effect, here's the codex entry:
In a droplet system, tanks of liquid sodium or lithium absorb heat within the ship. The liquid is vented from spray nozzles near the bow as a thin sheet of millions of micrometer-scale droplets. The droplets are caught at the stern and recycled into the system. A droplet system can sink 10-100 times as much heat as DRA strips.
It seems like it could work but also seems like its just science fantasy. I guess it would depend on how long the droplets would be out in the vacuum of space.
So to make it simple, I'll give out some numbers, let's say 1,000,000,000,000 droplets (about 1 Liter worth I think) (each droplet with a radius of 5 microns, the normal size of mist droplets) of liquid sodium at 850°C (a bit below its normal earth atmospheric boiling temperature) out in space for 30 minutes. What Temperature would the returning sodium be? Keep in mind this isn't an accurate scenario, just some numbers thrown out. If you want to provide a more realistic scenario I would be more than happy. Thanks!
(No, it's not off-topic, do your bloody jobs right, don't look for excuses to not answer it. it's not engineering, I'm not asking someone to build it, I'm simply asking how much the temperature would go down.)
