Cool, but rather disturbing also.

I'd assume that the power doesn't drop much at all with range... Did the person filming have it in a room fully tiled from floor to ceiling in matte finishes to keep it from scorching paint, wallpaper, etc?

Frankly, the implications of this kind of tech are much more disturbing to me than, say, Google Glass.

I'm thinking of all those stories of airline pilots being blinded by pocket lasers... and those ones are only toys

Yes, but can you market this to millions of kids for billions of dollars like Mr. Lucas did?

There's the rub.

Is anyone else thinking this is the perfect arson tool? You don't even have to go inside the building you want to torch, just shine the laser through a window at a cardboard box or something.

Scary implications indeed.

yeah yeah yeah, but

Yeah I was waiting for the "ALIEN ARM" demonstration.

But how good is it at severing limbs?

Well the inverse square law will take the edge off at range.. still:
'DO NOT POINT LASER INTO REMAINING EYE'

I wonder how much though. If you point a laser at the moon then the beam will cover much of its surface. Wouldn't make much of an arson target anyway, although an aspiring tag artist with a powerful, precise enough laser (probably an array of lasers high up in the mountains tbh) with enough time could make a mark.

Anyway, I think your right. The laser wouldn't spread much but I figure you wouldn't have to go that far before the laser beam isnt concentrated enough to produce a flame. Still, point it somewhere with flammable fumes in the air, say a gas station and focus it on something matt, black with a low flash point and you could make it a very bad day for somebody.
