This is a subject (space radiators) I know about.
If you have a small object that is dissipating a lot of heat,
radiation won't keep it cool nearly as well as a flow of cold water.
Poul Anderson wrote a story, Satan's World, long ago where the value
of planetary heat sinks was the main story element.
The huge radiation area of a planet is just about free.
On the number of Transhumanists, there was a list on Wikipedia that
had around 100 on it. I found a list (that includes me, but leaves
out many prominent transhumanists) of 24. My estimate is that the
number of people who identify as transhumanists is within a factor of
5 either way of the number of people signed up for cryonics. Since
there are about 2000 people signed up for cryonics that would put
transhumanists at 400-10,000 people.
