Didn’t know it existed yesterday but I want one today!

Guy goes by the dock two feet out of the air! Too cool.

Pretty cool, but $6k?

Looks like fun! A couple of companies are making those now. https://www.getfoil.com/?gclid=EAIaIQobChMIp7KDpfSk9AIVDmKGCh0gEQiREAAYASAAEgKD9vD_BwE

So, is the lift generated via Newton's or Bernoulli's theory?

Bernoulli's principle does not, in itself, explain lift. Newton's laws do.

Draw your own conclusion.

Sharks....

 

[Salty]

Sharks....

With lasers?

 

[texasclouds]

PFM…pure friggin magic

 

[Zeldman]

With lasers?

Of course. Sharks are getting pretty high tech these days...

 

[Spring Ford]

No. Not cool

Bernoulli's principle does not, in itself, explain lift. Newton's laws do.

I conclude that Bernoulli and Newton are two derivations of the same principal. But I also note there is no force vector from Bernoulli.

Give me the sharks.

Bernoulli's equation is easily derived from Newtons laws. But, Bernoulli's equation is simply the conservation of energy along a streamline - if you want to legitimately use it as part of the explanation of lift, you have to first invoke circulation.

When I first saw that video, I thought it must not be that hard... until I watched someone else try.

It's Poseidons theory

If it derives from Newton's law, but needs additional to match it, then the derivation is flawed. An equation should be equally "equal" in all forms.

That's Zuckerberg??? I am really resisting the urge. I mean like really trying. If I can't, see all ya'all whenever they let me back in here.

No. Not equal. Derived from given the assumptions that make B. valid. https://drive.google.com/drive/folders/1RCcCqI2kAcE7BhTyj1RKV44wR_2dYPBR

I can't even manage to balance on a regular paddle board. I'm sure I couldn't manage this.

Might be easier since it's under motion unlike a paddleboard. Sort of like a jet ski being somewhat unstable at rest, but once you're moving forward the stability goes way up due to force of the water.

I think it helps to have surfing experience.

 

[Shawn]

An e-Foil is on my bucket list but the decent ones are still $8-1$2K...that is tough pill to swallow for a 30-45 min run time toy.

Local shop here in town does a demo clinic and I may go try that out...or may not so I don't have the urge to spend another $12k!

Concussion machine, but it looks cool.

If you can't get hurt by it, it is not worth having..

And be 21 or younger.

Meh... I learned to surf in my late 30s... anyone can do it.
