Tesla Roadster can self-recharge compressed air, recharge time undisclosed

Tesla said its new Roadster can refill its compressed-air tank on its own by collecting and compressing ambient air, but it did not disclose how long recharging takes or how many times it can be used consecutively. The Roadster comes in Performance, Thrust and Rocket versions, with thrusters limited to higher trims. Demonstration specifications included two 600-litre pressure vessels and about 250 kg of compressed air, though it is unclear if that applies to the Thrust model.
