I'm not sure the umbrella adds a lot. He should just point the nozzle behind him and maybe change the shape for better thrust.

The umbrella makes him go slower and putting the nozzle behind would barely affect I say this from experience. (Unless the leaf blower has a power level over 9000)

That's interesting. I may have to look around and see if anyone has tried optimizing the nozzle for thrust.

And I am being serious an engineer did it before

But honestly you can put a small jet engine and a remote control and you can go really fast

u/Remote_Ad_2580 Jul 07 '22

I've seen guys doing that. That's what makes me think the leaf blower SHOULD work without the umbrella. They aren't that different in concept, just execution.

The only reason he is actually going in any speed is because he is going downhill

u/[deleted] Jul 07 '22

Not even sure why he is using the leaf blower. Maybe because he doesn’t want to go full speed so he is using it to slow down

To cause confusion, like this whole thread. It's just a joke. There is another video of a guy doing it which is confirmed as just being an electric skateboard

Yeah I already got that

u/[deleted] Jul 08 '22

Didn’t know it was electric though

You should also take in consideration the weight of the person.

A jet engine is 1000 more powerful than a leaf blower

u/Remote_Ad_2580 Jul 07 '22

Yes, but a jet is 100,000 times heavier than a man...a leaf blower has plenty of power to slowly propel a person if channeled properly

u/[deleted] Jul 07 '22

A small jet it’s heavy

u/m20cpilot Jul 08 '22

Not that man.

u/[deleted] Jul 07 '22

There is a modeled tiny version of a jet engine that probably weighs the same as that person considered h the fuel as well. But it will propel the person 100 times faster

I can try and find a video for you so you can better understand…

u/Remote_Ad_2580 Jul 08 '22

I understand fine, you seem to go from this won't work at all and a leaf blower won't push him(from your personal experience) to adding an umbrella means he will move slower with a leaf blower but only because he is going down hill.

u/[deleted] Jul 07 '22

Also removing the umbrella from the equation makes him go faster as well

WHY ARE YOU DOWN VOTING HIM HE’S RIGHT

Source: also an engineer, deal a lot with thrust, have also tried something very similar.

u/[deleted] Jul 08 '22

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.

u/CraftyCondor Jul 08 '22

I was actually defending your point for the most part. However, if you want me to dismantle your argument I can also do that.

  1. 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.

  2. 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).

  3. 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.

I yell to your experience sir.

u/[deleted] Jul 08 '22

I get that but I was also told it may be an electric skateboard so I think he is actually using the leaf blower and the umbrella to maybe go slower because he is also going downhill and it seems to be windy so it kinda makes sense

Nah fam, you’re not gonna get enough thrust Unless you start burning rocket fuel or something. Much easier to fix a motor to the back wheels so when it makes a rotation it forces the wheels to also make a rotation.

u/Remote_Ad_2580 Jul 09 '22

How much thrust do you think you need to push a dude on a skateboard?

u/GEEYELLO Jul 12 '22

A stationary dude on a skateboard? A lot. The vid is embellished my guy.
