I hope one day this technology can be used to remove bottom paint, varnish, etc. and put sand paper in the dust bin of history.

That's pretty slick.

Any idea on what it costs or how many amps it pulls?

Not sure, but it uses a YAG laser. These generally require very high energy, the one in the video was a 1000w laser. What wasn't shown was the large trolley the held the rest of the unit. YAG lasers also tend to chew up their own optics so I am not sure how long between replacing parts.

Very cool for sure, but way too expensive to be put in use on a boat yard for hull cleaning any time soon.

Based on a Reddit string, Adapt Laser Systems was selling two demo units: 500W for $275,000; 100W for $145,000 a year ago. Rent 500W for $7,500/week; 100W for $4,500/week.

Need to stop at Lowes on the way home to buy sandpaper.

One careless laser wielder, and that laser beam is going to shoot like a gun and do a lot of damage, is what I think, blind someone or burn someone and maybe far away.

It's not a laser weapon for crying out loud.

There used to be a gilding company in my office building. They had something similar to this over 15 years ago. It had a very small output (like the size of a laser pointer) but they could take paint off a candle without melting the wax. It was incredible to use (they let me clean part of a candle off). The problem was it was so expensive to buy they went out of business!

What happens to the paint? There is no apparent residue, dust or liquid in those videos. Is it just vaporized? And if so, should the guy have a mask of some sort on?

When I took paint off the candle it completely vaporized (the paint that is, not the candle wax!) . I remember a little smoke but no smell.
