Driven up the wall

I spotted this on facebook and although I don't agree with all the comments like, "my missus has been driving me up the wall for years", it's an interesting application of a basic principle of physics.

F space equals space mu N

The fans provide a force that pushes the car into the wall increasing the Normal force making the friction large enough to hold the car up.

As another wag pointed out; "a drone with wheels that can't fly". It somehow doesn't seen so great anymore.
