Original Note:
This system does not "push" the skate board, it is just going down a slope. According to Newton laws, the airblower pushes the skateboard backwards, while the umbrella pushes it forward, cancelling the effect. The self-blowing sail myths has been debuked many times. https://youtu.be/M7-h3FO-KKo?si=8BeM798gCOCS7tuk&t=342 https://en.m.wikipedia.org/wiki/Newton's_laws_of_motion
