Elon Musk on future energy for AI:

“I expect that within five years, running AI systems in space will be far more economical than running them on Earth. Well before we run into energy constraints here, the lowest-cost option for large-scale AI will probably be solar-powered compute satellites. My guess is we’re about four to five years away from that.”

NVIDIA’s Jensen Huang added:

“Look at the supercomputers we’re building now. Each rack weighs around two tons — and about 1.95 tons of that is cooling alone. Now imagine shrinking that entire system down to a tiny, ultra-efficient unit. That’s what the next generation of GB300 racks could look like.”
