Does your lifetime extend to before 1970? We had reusable launch vehicles at that time. We had propulsive rocket landings in the 80's. Electric cars have existed for longer than gas-powered cars.
By contrast, no analog for the "hyperloop" has ever existed outside of sci-fi novels.
- SmartJerry 3y agoWe have had pneumatic tubes as well since 1799 and they've been used by many companies in the past. The only thing novel about the idea was the scale and technology behind scaling it.
- cesarb 3y ago> We had propulsive rocket landings in the 80's. Didn't the Apollo project use propulsive rocket landings to land on the moon (which was kind of necessary due to the moon's lack of a dense enough atmosphere)? IIRC, that was much earlier than the 1980s.
