I Built the Worlds Largest E-FOIL

"I tried to get him some help, the voices don't stop man", awesome!

Forget the Segway, dude just made the SegWave

You should go full size. Put wings on your whaler.

[SodViber]

Your wing is actually better than you know because there is a special high lift coefficient only possible at the surface of water where you can have a higher angle of attack without stalling because the surface of the water curves down without detaching behind your aerofoil, unlike the stall in bulk air or liquid. By operating just below the surface with a big wing, you have the ultimate flexibility for angle of attack range, not possible anywhere else in aerodynamics! Congratulations, you're operating in a unique domain where no bigger or deeper hydrofoil can go: the ultimate sweet spot for all aerodynamics.

Put mirrors on the "legs" that separates the board form the wing. It would look like you are hovering.

Ok, so... now remove most of the board, leave just a square that you actually stand on. Let it be a goofy hydrofoil-scooter

[winstonbeede]

The wake that it makes is pretty crazy

[jeffreychow]

Amazing. When you said powered wheelchair for the sea it made me think how cool this would be for persons with disabilities as a sit down version. The slow, docile speed would be perfect. I’m trying to make a daily usable, off-road wheelchair as we speak and you’re def an inspiration.

[meatfeast]

congratulations on making the worlds first hydrofoil segway!

[Wingmanl]

You may have inadvertently hit upon something unique here -- an e-foil design that is not only more approachable due to its slower speed and more docile handling characteristics, but also one that is cheaper & simpler to build because of its lower power draw requirements!

5:10 that board needs pedals for direction and a butt emplacement, with a back rest. That way, you can leave your hands free for activities and use your back to control pitch, while steering with your feet.

[soopergoof]

Learning to ride it as it is just like Wrights' 1903 Flyer. They had to continuously horse it in pitch (using the canard) because the main weight was BEHIND the CG. Same problem with the 1905 Flyer. They didn't achieve auto-stability until they got main weight FORWARD of CG. To thier great credit, they had become expert at "horsing" it in pitch, just as you're doing. Had they achieved auto-stability first, they woulda missed all the fun learning.

[AerialWaviator]

Daniel, have you considered adding a small canard on a shorter mask at the front of the board? 

A canard would help with pitch stability and help keep the main wing from stalling as could be positioned to stall first, or come out of the water if alpha got too high. Could experiment with size of canard from very small to small. Another option is adjusting canard angle based on how close it is to the water surface (a mechanical float arm, or using sonar).

Adding wing dihedral would make tips come out of water when riding higher, which should allow to cruise faster (or a gull style .. down hedral inboard, with up hedral past mid-span).
For added height and fun, could build a bi-wing hydrofoil. Add smaller wing below the larger upper (solar) wing. Can start slow, and climb higher to go fast and be more maneuverable. You could have the worlds first, and largest bi-foil!

As a long-time viewer who recently moved to Seattle; I must say, it's really neat recognizing places in your videos now.

[patrickradcliffe]

9:26 can be solved by wing sweep. I had a feeling during the build it was gonna be majorly pitch sensitive. I would think a 15° wing sweep would dampen out the pitch sensitivity.

[MrHUGOLADEIRA]

It's wonderful and amazing to see you discovering and loving this world of hydrofoiling too! I'm passionate about surf and wing foiling and I think I'll stay that way for life.

[CaveyMoth]

That Bombas sponsor spot was a really good...pitch.

Think of how rich you could be if you successfully brought this concept to the consumer market.

[trevhedges]

16:45 oh I should have waited, you actually had the same idea, near word for word.. 😂

[LoreTunderin]

Now you should try a variable geometry swept wing e-foil, like an F-14 Tomcat of the sea.

[StevenIngram]

I was thinking, if you ever wanted to try to make one that is speed oriented, and wanted it to looks "science fiction." I'd recommend building a reverse trike foil. 2 jet plane shaped foils in front, 1 in back - all powered with water jets. You'd basically be riding on 3 underwater jet planes flying in formation. :D
