How much does a telephone pole of tungsten weigh?
It might sound more ridiculous than intimidating at first blush, but when that “telephone pole” is forged from solid tungsten, weighs 100kg, is rocketing through the atmosphere at 7 kilometers per second, and amassing a kinetic energy of 2.5 gigajoules, a bizarre image becomes far more menacing.
What happens if you drop a tungsten rod from space?
The “rods from god” idea was a bundle of telephone-pole-size (20 feet long, 1 foot in diameter) tungsten rods, dropped from orbit, reaching a speed of up to 10 times the speed of sound. The rod itself would penetrate hundreds of feet into the Earth, destroying any potential hardened bunkers or secret underground sites.
How much does each nuclear warhead cost?
W80-1 warheads) ~$16.3 million each. or up to 20 nuclear gravity bombs ( B61-7, B61-11, B83) ~$4.9 million each.
What does a nuclear warhead cost?
Basic weight is about 700 pounds (320 kg), although the weights of individual weapons may vary depending on version and fuze/retardation configuration. As of 2020, it is undergoing a 12th modification. According to the Federation of American Scientists in 2012, the roughly 400 B61-12s will cost $28 million apiece.

What is a tungsten rod used for?
Electrically Conductive Tungsten Copper Rods Use these rods for electrodes in the electrical-discharge machining of dense material, such as tungsten carbide— they’re 75\% tungsten for wear and arc-erosion resistance and 25\% copper for electrical and thermal conductivity. They’re also known as Elkonite rods.
Where is Elmet tungsten rod made?
Elmet’s 99.95\% Pure Tungsten Rod is made in the USA at our fully integrated Lewiston, Maine production facility. As with all of our products, we manufacture tungsten rod in a full range of sizes (.02″ to 1″) with top of the industry lead times. All Rod Products are made from 99.95\% pure tungsten pressed, sintered and swaged material
How much does it cost to fire a tungsten rod into space?
One Quora user who works in the defense aerospace industry quoted a cost of no less than $10,000 per pound to fire anything into space. With 20 cubic feet of dense tungsten weighing in at just over 24,000 pounds, the math is easy. Just one of the rods would be prohibitively expensive.
Are tungsten welding rods heat conductive?
This high-density tungsten alloy is thermally conductive, so it dissipates heat quickly without deforming at high temperatures. These rods create stronger welds than standard TIG welding rods for steel. Make welds quickly with these fast-melting rods.
