The secret Nazi plan to blow up cities and boil oceans with a mile-wide 'SUN GUN'
Daily Mail ^ | 2nd April 2013 | Mark Prigg

'It may sound like a something a Bond villain would propose, but these amazing pictures reveal the secret plans drawn up by the German army to create a mile-wide 'space gun' powered by the sun.

The giant mirror could be used to focus the sun on a target - rather like the magnifying glasses often used by children to create fire.

The pictures, from Life magazine in 1945, reveal to its readers how 'U.S. Army technical experts came up with the astonishing fact that German scientists had seriously planned to build a ‘sun gun’.'

I had always been intrigued as a child about little magnifying glasses that would make grass, leaves or twigs catch fire.

If the Germans were thinking of some kind of focused beam or parabolic dish I’m afraid that the concentrated rays of the sun would burn up the parabola.

the sun’s rays are quite diffuse.

all spacecraft receive direct sunlight and do not burn up.

the parabola would receive diffuse rays and the rays would only be concentrated at the focal point of the lens.

only at the focal point will there be burning rays.

Sadly for the Nazis, the laser pointer had NOT been invented yet

While the Germans were allocating scarce resources on sun guns, super tanks, and the like, the Soviets were mass-producing cheap T34 tanks.

One reason Germany lost the war.

I made one of these a few years ago. I stretched aluminumized Mylar over a round 2 foot pizza pan. I put an air fitting in the bottom of the pan and attached a squeeze bulb to it so I could pump a partial vacuum beneath the Mylar.

The resulting focus-able concave mirror worked well for catching paper on fire at 50 feet with sun light.

The solar constant is approximately 126 watts per square foot uncorrected (upper atmosphere). Corrected for atmospheric dispersion at the earth’s surface it’s down to about 104 Watts per square foot.
When you compute the area of Hitler’s mirror or lens, it could be a considerable quantity of heat.

As a child, I was amazed to find out that ants would spontaneously combust as I was studying them under my magnifying glass.

Yep. We're building a few, darned few F-22s and F-35s, while China...

(from ‘Plan 9 From Outer Space’)

Eros: “Take a can of your gasoline. Say this can of gasoline is the sun. Now, you spread a thin line of it to a ball, representing the earth. Now, the gasoline represents the sunlight, the sun particles.

“Here we saturate the ball with the gasoline, the sunlight. Then we put a flame to the ball. The flame will speedily travel around the earth, back along the line of gasoline to the can, or the sun itself.

“It will explode this source and spread to every place that gasoline, our sunlight, touches. Explode the sunlight here, gentlemen, you explode the universe. Explode the sunlight here and a chain reaction will occur direct to the sun itself and to all the planets that sunlight touches, to every planet in the universe.

“This is why you must be stopped. This is why any means must be used to stop you. In a friendly manner or as, it seems, you want it.”

Colonel Tom Edwards: “Why, a particle of sunlight can’t even be seen or measured.”

Eros: “Can you see or measure an atom? Yet you can *explode* one. A ray of sunlight is made up of *many* atoms!”

Jeff Trent: “So what if we *do* develop this Solanite bomb? We’d be even a stronger nation than now.”

Eros: [with disgust] “Stronger. You see? You see? Your stupid minds! Stupid! Stupid!”

Jeff Trent: “That’s all I’m taking from you!”

Just like with the magnifying glass, the concentration of the light doesn't happen at the parabola, it happens at the focal point away from the parabola.

Re: The giant mirror could be used to focus the sun on a target

Well, I use my smaller mirror... the same way--

Focusing on... my target!

And unlike them gall durn Nazis, I hit my target... time after time after time--

He does... ya know!

Quite correct. Hitler had an unusual fascination, one might say obsession for exotic and strange weaponry.

Hitler’s greatest asset in WWII were the military minds who made up his general staff and his leading panzer commanders-—men whose advice and counsel he routinely ignored-—another major reason Germany lost the war.

Not to worry. James Bond took care of this problem in “Goldeneye.”

There was a book by an electrical engineer called, “How to Turn A Microwave Oven Into a Ray Gun”.

He used a busted 5KW commercial oven’s innards to set plywood on fire at 500 feet. Boiled a cup of water in 4 seconds.

Just think of what would happen to the operator if the beam reflected back!

I’ll bet this stuff is on YouTube now.

A fascination shared, curiously enough, by Churchill: who spent a remarkable amount of time and energy pursuing sometimes quite bizarre projects - some of which worked, others didn't.

Several questions(actually one with several subsets). What is the temp of Mercury's surface? What is the temp of the moon's surface on the sunny side? A parabolic mirror would provide ample temp for burning things. Don't believe it? Buy a reflector telescope and then use the mirror to focus the sun on something flammable, see what happens.
