Things You Can Do With A Giant Fresnel Lens

Ant writes "Here is a link where this guy always wanted Edmund Scientific's Giant Fresnel Lens. 'Melts asphalt in seconds!' the ad said. When he went to graduate school he met several other people with the same enthusiasm for aimless destruction through bizarre means, and just enough combined cash to make it happen. Thus the reign of terror began."

EEK!

Lets hope this doesn't get into the wrong hands! This can be worse than WMD's!

Re:EEK!

[Dizzle]

It already is because this actually exists.

I know; I just finished with the AP Physics B test, and I thought I was rid of specific heats forever. Why, God?? Why won't they die?

Burnination

[OneFootIn]

And to think, when I was a kid I had to settle for burning ants with a magnifying glass.

Heh! When I was in High-school we took things a step farther by taking Mr. Bouknecht's overhead projector lens out of the housing. [I'm quite certain] it's a true Fresnel Lens - but the point is that it was like a magnifying glass on steroids. We had to be careful just walking out into the parking lot with it because if it caught a friends leg and the sun at the right angle, they'd be in a world of hurt.

Aaahh, fun times being a juvenille. My advice to the next generation though - be as mischievious as normal, but don't do anything stupid or anything that will get you thrown in jail. Be intelligent with your "inevitable" delinquency [you call it rebellion] - we've all been there - however don't get anyone hurt or needlessly damage property.

Life is much more exciting as an experienced adult making thousands of dollars a month. Trust me on this one all you guys. Science is fun, but it can also be very dangerous... Be safe - because if you go to jail or die, the guy you hate will likely reproduce and you never will. And that would suck.

Now you can burn like......two ants!

Science is fun, but it can also be very dangerous... Be safe

My father once caught me making gunpowder using a chem lab kit he'd bought me and an old mortar I'd found in the garage. His first reaction was "Idiot kid!" Then it was "Oh, wait, that's what I used that mortar for when I was a kid. Let me show you how to do it safely." Basically wet the ingredients down so it doesn't accidentally catch fire while you are grinding it. I suspect he'd learned that one the hard way. I'm big on the safety angle with my kids now, too. In my case its a result of an experiment with some gasoline and an Estes rocket engine when I was a teenager.

Ants

[eightball01]

Now the ants really don't stand a chance!!!

Re:Ants

[wankledot]

Even ants the size of horses.

DOH! :(

Ants? I'm more worried about the humans.

Terrorism...

I wonder what his Terrorist Quotient is?.

A use for AOL CD's

[ErichTheWebGuy]

A friend and I were discussing what to do with all of our AOL CD's. We both came up with the idea that you could make a similar device out of them.

Welcome! You've got fire!

All we need now are...

[Fiz Ocelot]

Sharks with...giant Frensel Lenses attached to their heads!

Giant Fresnel Lens ...

[john82]

Meet Brood X of the 17-year Periodical Cicada.

Snap! crackle! pop!

Why waste such a monster on mere ants. I realize there are some of you out who would think of a certain movie and popcorn (lots of popcorn), but you've got to agree this is more unique.

If only I had this as a kid

[Anonymous Coward]

This is just like the magnifying glass and ant game only this scales up to poodle sizes. Oh well. If I ever have a son...

If you like burning up stuff with a lens...

[PissingInTheWind]

you'll love this flash game: Ant City

Would this be possible?

[Fiz Ocelot]

Would it be possible to build a giant one, say 100 square feet, and focus it into a fiber optic type of cable, essentially using it for a cutting laser?

Or what if you had a few massive ones in space, could you focus enough energy for use in a fusion reactor? You'd amplify all of that free energy and I don't really know what I'm talking about. Perhaps you could attach it to a shark's head.

Hmm, The Ant Equivalent

[Danny Dale the Not-S]

of a Nuclear Bomb.

Imagine kicking over an ant hill, then frying thousands of the little fuckers with each sweep of the beam when they come pouring out. Considering you can melt nickels and cut soda cans in half with this thing, it's possible you can actually [i]glass[/i] that anthill!

Just make sure it's fire ants. Those bastards deserve it...

And remember

[Flower]

Do not taunt giant Fresnel lens.

Avoid antabuse at all costs

[plover]

A buddy who was in the army was busted for showing up drunk, and they made him take antabuse. According to him, when you're taking it drinking even the smallest amount of alcohol makes you puke puke puke.

Re:Mindless

[mlh1996]

But, onto the other point: many geeks like high amounts of kinetic energy. It's true. Often, this love tuns into the irrational lust for wanton destruction of random objects.

Which leads to my observation that, when presented with a large electromagnet, a REAL geek immediately constructs a railgun

I mean, really. Is there anything more beautifully destructive than a railgun?

So I'm reading this to my wife...

[jbellis]

... and I come to the $99 part. The first thing she says is, "You can't have one."

"But a professor," I try to explain...

"You can't have one."

Obligatory "Death Star" reference

[Cirrocco]

I can't believe, with all the talk of putting one in space, nobody has used the words "DEATH" and "STAR" just yet.

Glad I'm the first. I think.

pfft

[ShadowRage]

I melted asphalt with good 'ol gasoline.

Re:I have one of these.

[ShaunC]

Is there anything else anyone thinks I should burn with it? it's in my garage.

That depends. Do you happen to live near Lindon, Utah?

I don't know what you were doing in chemistry (probably wearing the proper equipment) but lye burns like all hell once it gets through the first couple layers of skin.
