[extropy-chat] Singularity heat waste

[George Dvorsky]

This comment was recently posted by "Chris" on my blog (responses welcome):

	"Does anyone know if any work has been done on the subject of how much 
waste heat would be generated by a singularity event? I'm thinking in 
terms of the fact that all computation, like all physical action, 
generates at least some degree of waste heat ( just no getting around 
thermodynamics) Assuming our civilization gives rise to a computational 
matrix that independently evolves in processing power exponentially, 
wouldn't that result in a catastrophic and possibly terminal heat-shock 
to the host-biosphere? Maybe that's the fate of all civilizations that 
reach singularities. I'd love it if anyone has any ideas to share on 
this..."
