It's sad that people thought it was real, forget about lasers and stuff it's basic common sense. A AAA battery doesn't store enough power to drive a laser capable of burning hair for any reasonable amount of time. When the laser isn't interrupted by the hair it has to go some where which means that heat is produced, if it can get something hot enough to burn the hair off it would get hot enough that you won't be able…

And laser hair removal doesn't even destroy the hairs, it uses the hairs to transmit heat to the hair follicles to destroy those. Destroying the hairs themselves would require even more energy.

> It's a testament to human stupidity that something this blatant managed to get $4M. That's a bit harsh. Most people don't understand technology on a functional level. Ask a "regular" person how programming, the internet or their mobile phone works and they won't be able to give you a technical explanation. In fact, most modern technology tries to hide the internal workings.. "it just works".

Heck, ask a programmer what a MOSFET is.

A Star Wars character?

I've done laser hair removal, and while it does hurt like a bitch, and does only work on dark hairs, the claims were that the razor would use a wavelength that targeted all hair (I don't know enough to say that's not plausible), and presumably they'd use a short enough focal length to only hit exposed hair, rather than the normal method of focusing on the hair below the surface.

Doesn't get around the smell, power requirement, or heat output though.

Since we all check the comments first, here are some links: KickStarter project page (suspended): https://www.kickstarter.com/projects/skarp/the-skarp-laser-r... IndieGoGo project page (they re-posted the project there after being suspended): https://www.indiegogo.com/projects/the-skarp-laser-razor-21s... Demonstration video: https://www.youtube.com/watch?v=aOLwNJ7TXWA

And of _course_ the Indiegogo project was posted as Flexible Funding...

There's no laser there. If there was a laser there it would be a significant hazard to everybody in the room, so it's good it's completely fake. With the sort of power you would need to be cutting hairs in any capacity simply looking at diffuse reflections (think a laser dot at a wall) would have the ability to permanently damage your vision. The video is someone fooling around with a piece of aluminum and a hot wire…

I don't agree, their demonstration video is enough without further domain experience to see that it is at a minimum ineffective at what it claims. If it was really supposed to be able to give you the smoothest shave ever, they would at least have a video without the participant flinching every time they burned themselves with the hot wire.

Not everybody got into programming on the soft side. But I agree with you that on average most programmers would not know what that is.

Especially today, now that most programmers aren't hobbyists who found a job matching their skills but people who explicitly learned to code because there's shitloads of money in the industry.
