Could AI really operate from space? Shane Hewitt and Greg Fish take a grounded look at the futuristic dream of orbital data centers — and the science that makes it far more complicated than it sounds.
Greg explains why cooling in the vacuum of space is nearly impossible without expensive, robotic maintenance systems and how Earth-based locations like Canada already offer natural advantages with cold climates and hydropower. Together, they unpack the environmental realities, the economics of “green” tech branding, and the motivations behind grand tech visions from billionaires.
A sharp, skeptical look at where innovation meets impracticality — and why the future might still be built closer to home.
