alt Hacker NewsI think “a fan or 2” is underselling the technology here. It’s not about the weight of the car but the force that the atmosphere presses on its surface area. This is well-established physics that has been demonstrated by others so I don’t know why you’re questioning this and not some of the wilder parts like the flying.
Also don't undersell how wildly impractical this known technology is - it requires a skirt that in order to get close to the ground, which will abrade. It loses traction dangerously if the seal is broken, it's very loud and energy intensive. It sucks up dust, pebbles and other road debris and spits them out at other road users, and it takes up a lot of volume in the car. As do those thrusters.
This is a circus stunt.
