that's been going on for quite some years now, if you've never seen the jumbo jet mounted one they started some ten years ago now. copying what the LA ufos had when some missiles were fried mid air, if you read about ufo's and Los Angeles of about half a century ago.

ever see the youtube vid of a kid that took about 30 or 40 lasers and made a laser canon so bright he wore a welders mask to avoid going blind? imagine if all that radiation was focused with a lens into one dime or less sized spot, and how about infra reds you can't see?

like I said when this video was posted the first time on RR, some 60 years of development and this is only as far as we have come with lasers ??? I'm betting not, if they are showing this, we got something much better

interesting, your dvd player laser might reach 400°f while the typical oven or hot plate will cook and burn food at 350°f while pasturizing food occurs at 140°f. Aluminum melts at 800°f and most steels twice that more or less. Do a little multiplication and you see what can happen, laser sintered metal fabrication. Multiply that potential by x and you get,,,,,,,,.

There are things the top level scientists don't want the public to know, to protect them from themselves. Projections of the future have been made, still they can't spend more energy dealing with the nasty problem of nuclear energy waste,

was too lazy to research it first, point was in how multiplying potential results in very dangerous things. Aluminum alloy at 865f is not far from 800f, not far.

Thanks for the link, that's a good one.

I have a laser cutter. It is an IR and I can tell you, the beam is totally and completely invisible and will burn thru flesh in less than a 1/4 second. And mine is only 40 watts. Keep in mind, lasers are light, so mirrored or highly reflective metals are very difficult to damage.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?
