And if you intent to use gas/ice clouds as defensive measures - is that possible? I mean given the size of ships, the speed and the weapon systems - is it possible to fill an large enough area of space with such a cloud to make it a reasonably effective defense? I honestly do not have a clue but I would imagine you'd need quite a lot of tonnage to build up a cloud like that. And then you'd need to be able to get it where you want in a really short time, too. I dunno how liquids exactly behave in the vacuum of space but I'd imagine they form balls of various sizes.
Now say we take a weapons grade laser - it would have to have enough power to punch through some basic hull shielding (against regular cosmic radiation & micro meteroids and stuff). How many bubbles of whatever material is forming the cloud would it need to lessen the beams power enough to make it ineffective?
I like the idea, just don't see it how it works.
Ideas:
Well, I was kind of thinking of using space rocks.
If you were able to stabilize some of those floating space debris and either rig it directly onto your ship or kind of mount it on an autonomous platform you could use them as a passive shielding that takes the punches for you. Of course they are more or less dead weight most of the time, they are probably structurally unstable and whatnot. But it's an idea.
Crazy thought - rig one of them like a humongous morningstar to your ship and try your piloting skills
