Cooling AI chips in space with aluminum radiators

Musk estimates an aluminum radiator pointed away from the Sun could shed about 1,300 watts per square meter, versus roughly 250 watts per square meter generated by solar panels. He expects the panels to make up most of a satellite's mass. The post he replied to calls cheap transport of large amounts of mass into space the main obstacle. Another post argues that a vacuum makes cooling harder and doubts space data centers will happen.
