Nvidia CEO Jensen Huang argues that cooling orbital datacenters is solvable despite the absence of convection in space, because large radiative surfaces can dissipate heat and space offers ample room for them.

Claims
- Space offers abundant energy for datacenters but lacks convection, making cooling a significant engineering challenge.
- Heat in orbital datacenters must be dissipated through radiation, requiring large surface areas.
- Jensen Huang believes the cooling problem for space-based datacenters is solvable given the physical space available in orbit.
