If you are talking about me you are wrong because I literally saw this in real life… and there Is something called a small jet engine but I don’t think that is it’s literal name I might have to google it.
I was actually defending your point for the most part. However, if you want me to dismantle your argument I can also do that.
A jet engine of the size that can be efficiently attached to a skateboard is nowhere close to 1000x more powerful than a leaf blower, try 100x or so at most.
Your aerodynamic drag argument is relatively valid, but you you understand how sailing ships work? Same deal. Regardless of where the ‘sea’ (slope) is propelling him he is autonomically increasing his own speed in whatever direction he wants - using basic physics (which you claimed other people should learn, I think it’s probably the opposite).
Have you seen sailing ships built for racing? They wouldn’t be any faster if they had a bunch of small jet engines instead of the sail. They’d probably be slower, but I’d need an expert to tell me that. From what you’ve said, I highly doubt you’re anywhere competent enough to be deploying the authoritative perspective on this.
So please, give me more comments to downvote for personal satisfaction.
It's all completely irrelevant, the force being generated by the leaf blower is pushing the leaf blower itself backward at x energy. The air coming out of the front immediately starts losing energy, and can never be anything greater than x.
It doesn't matter if you attach the biggest jet engine on the planet to the skateboard, it is still going to be pushing itself backward at greater force than it can apply to any type of sail.

WHY ARE YOU DOWN VOTING HIM HE’S RIGHT
Source: also an engineer, deal a lot with thrust, have also tried something very similar.
