Physicist calls compressed-air car a scam: one charge would take a week of compressor time
rickasaurus · x · 2026-10-16
Quoting a hyped compressed-air car stunt, a commenter argues it will never ship: the external multi-stage compressor and heat exchanger needed to fill the tank once would likely cost more than the car, and an onboard setup would run for days to nearly a week per charge. He also flags the safety risks of 250kg of 10,000psi air in a composite tank inside a human-occupied vehicle. The original poster pushes back that it's still rad.
