India nuclear test - インド 核実験 By 222kenken The Smiling Buddha was the first nuclear test explosion by India on May 18, 1974 at Pokhran. The fully assembled device had a hexagonal cross section, 1.25 m in diameter and weighed 1400 kg. The device was detonated at 8.05 a.m. in a shaft 107 m under the army Pokhran test range in the Thar Desert, Rajasthan. Officially the yield was reported at 20 kilotons. Indian design was simpler and less sophisticated than the American system. The 6 kg of plutonium came from the CIRUS reactor at BARC. The crater produced by this detonation of a plutonium implosion device has been reported to have a radius of 47 meters with a crater depth of 10 meters.

Tsar Bomba - King of the Bombs - 57,000,000 Tonnes of TNT By flyboy172r The Tsar Bomba _______________ October 30th 1961 - The Tsar Bomba, King of the Bombs, Царь-бомба or Big Ivan. This footage is courtesy of the documentary "Trinity and Beyond", directed by Peter Kuran, and other footage is courtesy of the Discovery channel. The original footage was from declassified Soviet Archives. The music used is from The Planets Suite composed by Gustav Holst. The movement is 'Mars: the Bringer of War' Before I get into the details of the test, I want to clear up something very important. The title of this video is "Tsar Bomba - King of the Bombs - 57,000,000 Tonnes of TNT". Understand now that this test wasn't the result of a detonation of 57,000,000 Tonnes of TNT, but rather the nuclear yield EQUIVALENT of a detonation of 57,000,000 Tonnes of Trinitrotoluene. The actual weight of the device was 27 tonnes. And coincidentally, one tonne is taken as a metric tonne, or 1000 kilograms - (2200lbs). All units used in physics are metric. The reason the yield equivalent system is used is because the energy released from the explosion of a set amount of TNT is a constant. Second to that: I KNOW THE SCREENSHOTS AT THE END ARE OF THE CLOUD OVER THE GROUND. The reason I made a mistake was because when I made this video I was using a 6 year old CRT monitor with numerous problems, some of which with the shading. I greatly regret it butI cant be bothered removing/re-uploading the video again so Ill just live with it. The bomb was designed as a 100 Megaton device, not a 50 Megaton device. This was due to its 3 stage design: fission-fusion-fusion. There is fission initiator that when detonated, begins a fusion reaction. Then there is a further fast-fission detonation (With neutrons from the second stage) of a Uranium-238 tamper which boosts the yield by 50 Megatons. For the test, the Tsar had its Uranium tamper replaced with lead to reduce the maximum yield by half (To 50 Megatons). The blast yield was equal to that of a blast of 57,000,000 Tonnes of TNT....or to put that into context: The weight of 270 Empire State Buildings worth of TNT. This makes the Tsar the most powerful nuclear device ever detonated in history. Think of the destruction at Hiroshima. The Tsar was 3800 times more powerful than Hiroshima. The bomb's weight was 27 tonnes, and its dimensions were: 8 meters (26ft) in length, and 2 meters (6.5ft) in diameter. It was air-dropped, from a modified Tupolev Tu-95 Bear, and it used a nylon parachute to slow its decent to give the crew time to escape. The bomb was dropped from an altitude of 34,500 feet AGL (10,500 meters), and it detonated a little over three minutes later at an altitude of 13,100 feet AGL (4,000 meters). In this time: The Tu-95, travelling at a ground speed of 480kts (552mph, 864kph), travelled into the safe zone (about 45km from ground zero) and was therefore 79km away from the blast. When the bomb detonated, immediately the temperature directly below and surrounding the detonation would have risen to millions of degrees. The pressure below the blast was 300 pounds per square inch, ten times the pressure in a car tyre. The light energy released was so powerful that it was visible even at 1000km (621 miles), with cloudy skies. The shockwave was powerful enough to break windows at even up to 900 kilometres (560 miles) from the blast. The shockwave was recorded orbiting the earth 3 times. The mushroom cloud rose to an altitude of 64,000 meters (210,000 feet) before levelling out. The thermal energy from the blast was powerful that it could cause 3rd degree burns to a human standing 100 km (62 miles) away from the blast. The radius of the fireball was 2.3 kilometres (1.4 miles). The blast radius (area in which total destruction ensured) was 13km (8 miles). The most important thing to note is that this bomb was designed as a 100 Megaton device (Yield equivalent of 0.1 billion tonnes of TNT). If detonated, everything within a 48 kilometer (30 mile) diameter would be vaporised. Everything within a 195 kilometer (120 mile) diameter would be incinerated in a fireball. This would ensure total destruction of a large city like New York, Paris or London, as well as devastation on its outskirts.

Gas Prices Killing You??? By sm0ky40 UPDATE: I have been working the bugs out of our hydrogen system on the Ford Escort. Just this last Thursday morning I finished making modifications and since then everything has been working well. The system automatically pumps water in and automatically drains water from the water trap while on the road. The car is running smoothly and has a lot of power. We will soon start building kits and will continue to test our designs. Recently, I had to ask myself what is gasoline? Gasoline is a blend of hydrocarbons C11H24 - C7H16. So, gasoline is just hydrogen with molecular bonds to carbon atoms and it produces about an equal amount of water as it burns. Hydrogen is clean burning because it does not have any carbon in it and it only produces water vapor when it burns. I have been concerned about the effects of water vapor on the engine and exhaust system however every hydrocarbon fuel that we burn already produces water vapor and unburned hydrocarbon emissions. So, I have stopped worrying and continue to drive 370 miles each week with the hydrogen generators turned on. I have also discovered that sugar has everything that we need to make gasoline and other hydrocarbons like propane C3H8, Butane C4H10, or hexane C6H12. Vinegar is C2H4O2 but remove the oxygen and you get C2H4 which is highly combustable Ethylene gas. It is all a chemistry problem with fantastic results that can power our cars when oil runs out. Well, that is the update. Thanks for watching my videos and keep watching for my next mad science experiment. Here is a way to beat the ever growing prices of fossil fuels.This video originates at: http://www.livevideo.com/byte312 Tags: alternative, brown's, byte312, energy, gas, gasoline, green, hho, hydrogen 1 Downloads - Last from: http://downthisvideo.com/ (Your Blog here!) |

BMW at the Tokyo Motor Show 2007. BMW Hydrogen7. By BMWwebTV Soenke Kroll explains how BMW´s long-term EfficientDynamics vision of emissions-free driving can be summed up with one vehicle: the BMW Hydrogen 7. As the world's first luxury performance sedan with hydrogen drive, it runs on the most plentiful element in the world and emits virtually nothing but water vapor. With its capability of emissions-free driving while running on hydrogen, the BMW Hydrogen7 can drive in London without even paying the London congestion charge. Because the infrastructure for refueling a hydrogen internal combustion engine is not yet complete, the V-12 engine also runs on gasoline at the push of a button. The unique feature of the BMW Hydrogen7 is that it drives on liquid hydrogen, which has a much higher energy desity as if it were in geseous form. The BMW Hydrogen7 is a small series production vehicle of around 100 units prividing the proof-of-concept of BMW´s vision of emissions-free driving. Beyond showcasing the car at international Motor Shows, BMW wants the world's influencers to see up close, and try for themselves..

JAPANESE WATER POWERED CAR!! By raviwfc As per the claims it runs only on a 300W "Water Energy System (WES)" where WATER is the only FUEL. The basic power generation mechanism of the new system is similar to that of a normal fuel cell, which uses hydrogen as a fuel. According to Genepax, the main feature of the new system is that it uses the company's membrane electrode assembly (MEA), which contains a material capable of breaking down water into hydrogen and oxygen through a chemical reaction. A Japanese venture company, Genepax, has unveiled a car on that runs on water. All it requires is a litre of water. In fact, any kind of water to be exact, whether its river, rain, sea water, or even Japanese tea. Its an electric powered car that runs solely on hydrogen dioxide. "The main characteristic of this car is that no external input is needed. The car will continue to run as long as you have a bottle of water inside for you to add from time to time," said Kiyoshi Hirasawa, Chief Executive Officer of Genepax, after he proudly announced the company's invention. Once water is poured into the water tank at the back of the car, the newly invented energy generator takes out the hydrogen from the water, releases electrons and finally generates electrical power. "We highly recommend our system since it does not require you to build up an infrastructure to recharge your batteries, which is usually the case for most electric cars," said Hirasawa, who is hoping to advertise the car in time for the upcoming G8 Summit in Hokkaido, Japan. According to the company, 1 liter of water keeps the car running for about an hour with a speed of 80 kilometers or 50 miles an hour. The company has applied for a patent and is hoping to collaborate with Japanese automobile manufacturers to mass manufacture their invention in the very near future. As fuel prices continue rising and people look for greener alternatives, companies globally are trying to come up with alternatives.

Walter Lewin Makes a Battery out of Cans and Water By FreeScienceLectures http://www.FreeScienceLectures.com The best physics lecturer Walter Lewin makes another wonderful physics demonstration after having read a lecture on batteries. The battery he creates has a huge potential difference - 10 to 20 kV! You'll never believe what it's made of! It's made of two cans with bottom and top open and two other cans. And then water is let to drip through the two open ones. After a short period a spark comes up, then another one, then another one. Do you know how it works? If not, see the free electricity and magnetism video course by Walter Lewin at MIT's OCW! --- It's Never too Late to Study: http://www.FreeScienceLectures.com --- Notice: This video is copyright by its respectful owners.
