we alredy have one, it can melt rockets out of the sky. also if we were to use something to magnify the laser beam, a fresnel lens wouldn’t be the right choice, it would just refract into multiple beams

Judging by this, it shouldn’t be hard for us to make powerful laser based weapons.

i want one to burn ant mounds

Its only dangerous if you don’t know what your doing, plus you can very safely pass through the beam if you do it quickly.

I cannot believe so many people who use this methodology, which is brilliant I must say, without extreme safety measures at and around the focal point. Would you walk so casually around or stand next to a beam of fire that you could see? I hardly think so. Guys be really careful. I’ve seen the guy in the video walk right in front of a parabolic dish and burn the side of his head. This shit is dangerous and not a toy IMHO.

Sounds like someone lives in Israel

You need a adjustable table like a table saw for a precise focal point.

The Death Star would happen o.o

That would enhance a solar cook oven.

actually there is 1366 watts per meter squared
January 8th, 2010 at 12:57 pm
hmm what if you had a bunch of these aligned at the focal point of each magnification? imagine the power! MUAHAHAHAHA!
January 8th, 2010 at 1:39 pm
I can’t see why these aren’t used large scale for power plants and stuff
January 8th, 2010 at 2:11 pm
wow, is this real, can a lense actually do that, that fast?
if it was focussed enough onto one tiney point, and it was a really really sunny day, could it act like a cutting laser?

3 or 4 lenses.small steal boiler.steam engine.generator.whats the hold up?
January 8th, 2010 at 3:08 pm
