With compressed air? No. I don't care how "not joking" he is, the power density is just not enough to lift a car for more than a few seconds even if the entire car were filled with tanks. It's just common sense. Have you ever seen compressed air VTOL on anything?
He also claims it will allow the car to accelerate "at the limit of human endurance" which would imply thrust vectoring also.
Perhaps he's testing the limits of human credibility...
- olyjohn 8y agoEven if it would work... what would hovering even do that is beneficial? Without tires touching the pavement, you won't turn or stop well at all. You will bottom out over every speed bump and driveway and parking lot entrance, unless you're hovering like a foot off the ground. The efficiency gains from the decreased rolling resistance will certainly not overcome the juice that these things will suck down...
- dTal 8y agoParallel parking? (There are no "efficiency gains from decreased rolling resistance" if the tires aren't even touching the ground. Your wheels will spin without moving the car, an efficiency of 0%)

- dTal 8y agoThat's a fancy word for compressed air.
