Last time these folks were mentioned on HN, there was a lot of skepticism that this is really possible to do. The issue is cooling: in space, you can't rely on convection or conduction to do passive cooling, so you can only radiate away heat. However, the radiator would need to be several kilometers big to provide enough cooling, and obviously launching such a large object into space would therefore eat up any cost savings from the "free" solar power.

Their white paper touches on the issue, which seems slightly hand-wavy without much detail on quantification. They could potentially take advantage of heat gradients from deep space and dissipate heat to explore the Seeback effect.

Deep space? So they want to be outside geostationary orbit?
