Still no hoverboards, mind you.

Is there an anti squirrel version? Got a right problem in my back garden.

You should totally get one for your hollowed out volcano.

That was significantly less dramatic than the ALL CAPS title suggested it would be.

Fun fact- the geneva conventions ban laser weapons that could cause blinding. But have no comment to make about laser weapons that merely kill people.

Did somebody set up us the bomb?

Pmsl.

Genuine question would a mirror like glass paint would reflect (most of the energy of) a laser away? I would have thought long enough to avoid a 'bolt', not a focussed, long time beam...?

🤣👏🏻
I believe the amount of energy in the beam is enough to break down molecular bonds in the water vapour, and just cause a sort of halo along the beam, a bit like what happens with a lightning strike.

Have they not tried a gigantical magnifying glass yet? You can burn the shit out of all sorts of stuff with a little bit of sunshine...cheaper too I'd imagine 🔎

That's in a hangar somewhere waiting for the invasion of giant ant-men.

Am I allowed to be a massive pedantic bellend here?

The CCWC (Convention on Certain Conventional Weapons, I know...what can you do..?) is a UN treaty. It was signed in Geneva but isn't a part of the actual Geneva Conventions. The Geneva Conventions are mostly to do with the treatment of people in wars. (How to treat civilians, prisoners and wounded and so on) Protocol 4 of the CCWC is about causing blindness with lasers though...

Another fun fact is that the UK hasn't ratified part 5 of the treaty about explosive fragments left after wars. Because you know...Weapons sales...

Sorry, as you were

Review article on technology for military purposes:

https://newatlas.com/laser-weapons-future-warfare/52801/

Absorption of light and distortion of the beam path is one of the big challenges when implementing lasers for military purposes.

At high enough energy densities you get "self-focusing"- I recall this being a problem they had years ago when creating star wars type weapons:
