the article doesn't mention that orbiting data centres could make use of two clean energy sources for free:

1. solar

2. anti-matter

further, the heat generated by the data centres would be less of a waste product and more of a potential energy source. the laws of thermodynamics still exist in orbit, but the math is more favourable due to the lower temperature of outer space. 

i haven't looked at the equations, but it's feasible that google could launch something like the iss - not a satellite but a space station - that could hold massive arrays of data and be powered autonomously at increasing scale using a combination of heat, solar and anti-matter as energy. this could not be done on earth, where energy generation is an eventual hard limit on growth.

unfortunately, there are no clear laws in place in orbit. this is a potential issue regarding the use of the data from space.
