Does The 2nd Amendment cover lasers?...................

[Yo-Yo]

A laser strong enough to set one’s hair on fire from a kilometer away probably isn’t eye safe. So yeah, it’s not lethal, just blinding.

[BBQToadRibs]

That was my first thought. Significant eye damage would be possible.

Welcome the new lines of reflective clothing. We use lasers at work. They have a range of about 1,000 ft.for thermal sensing. We have bounced them off of carefully aligned mirrors and back. We have actually measured motor temperatures from three buildings away and three right angle 90 degree corners. Fun stuff.

It may actually be able to start a fire one km away under ideal lab conditions, but those conditions do not exist outside of the lab.

You notice it doesn’t say how long you have to hold the beam on the target................

[Red Badger]

... right angle 90 degree corners.

Are there any other kind?....................

For the benefit of liberal arts grads.

When mirrors are outlawed only outlaws will have mirrors.

[rightwingcrazy]

In the summer in Houston, maybe.

[roadcat]

Now how does one mount that frickin’ laser to sharks?

[RandallFlagg]

Anyone remember those, “Laser Weapon Blueprints,” they used to sell in comic books?

Any of you ever get one?

[Red Badger]

[IndispensableDestiny]

15-mm calibre weapon? Or do they mean 15 mm wavelength (about 20 GHz)?

[Red Badger]

Caliber...................
