Wow - so it started a day ago? And all of the $10k pledges are gone? Safe to say they'll reach their goal.

I'm amazed it's getting anywhere given how limited it is, but they seem to have glossed over that pretty well.

"our current technology requires special types of surfaces"

i.e. the giant sheets of copper or whatever it is they're using in their vid.

From Reddit
There is no magic going on here. It's just Lenz' law. We've understood the underlying physics for almost 2 centuries now. You can see this is what they're doing because they're using copper plate (obviously for high conductivity) to push off of, and you can HEAR in one of the videos of the thing the high pitch whine of magnetostriction in the device's solenoid coils. Note the pitch and loudness of the whine changes when the board is stepped on because the addition of weight to the system changes its resonant frequency and they're probably using a Hall effect transducer to dynamically adjust the power driven to the solenoids in order to maintain a constant levitation height. So now that we've established how the device works and that it's using legitimate, if boring, physics, it's completely obvious this setup will never be anything more than a very limited demonstration novelty for the following reasons: 1) you'd need a shitton of copper plate to make something like this work in sidewalks and copper is goddamn expensive, 2) the board needs A LOT of power to levitate; so if it's battery powered, which it looks like it is in the video, it's going to have a limited hover time of probably no more than a few minutes and if it's powered by induction or something then you're going to need even MORE expensive copper for the coils, 3) copper is not a superconductor and has ohmic losses like any other metal so it's going to get FUCKING HOT after a few minutes of use (like, melt the board and then the copper kind of hot).

Soooo, it's a toy, a novelty they may be able to sell a few one-offs to "look the future is here!" type demos, but it has no possibility of large scale commercial success for any kind of consumer application.

Maybe the people who can shell out $10k for one of these can also afford to repave their local neighbourhood in a compatible surface.

LOL. Thanks Darren, I was wondering about that, but didnt want to look like a fuckwit, thinking they had made something I couldnt get my brain around.

Has to be non-ferrous metal according to reddit. Preferably copper. Can't even leave a tv out for council clean up for 1 night without a copper gnome cutting the cords off it :)

I think your maths is broken, or they haven't sold 100 million watches to make 140 million wobbles.

Shonky, That is the original pebble.

Wabbit, Yes.

the original has sold 1 million, not 100 million, which is why he questioned your maths. $140 million would mean each watch cost $1.40 each, which is about the cost of an actual pebble.

My wife and I would take turns doing a level each in that game because we'd become so disorientated that we'd have to swap to regain our equilibrium.
