Re: Re-anodising heatsinks?
It's not just space-in-a-vacuum that denies cooling by convection: anywhere in zero-gravity experiences the same effect. There are lots of fans used for cooling in things like the ISS.
[Zero-gravity has other odd effects: a friend of mine is NASA's fire-suppression-in-space supremo. Without convection, fire behaves very differently in zero-G !]
