10年内有可能将小型核聚变投入应用

reals

前一阵的新闻，美国洛克希德马丁（lockheed martin，也就是设计F-35的高科技公司）宣布发明了小型核聚变反应炉，小到可以装到卡车上。虽然也有质疑的声音，但如果成真，对人类来说又是一大进步。

美国和日本已经将电动车投入市场，中国也在起步阶段。或许在5年后，加油站都开始导入小型核反应炉，电动车逐步代替内燃机车。

Experts Skeptical Of Lockheed Martin's 'Nuclear Fusion Breakthrough'

Ships, aircraft, and even entire cities may become fusion-powered a lot sooner than you might have imagined.

That's the word from aerospace giant Lockheed Martin, which announced Wednesday that a research team in its Skunk Works division has found a way to make a nuclear fusion reactor that's 10 times smaller than previously thought possible.

If they're right -- and some experts are skeptical -- the reactor would be small enough to fit inside a tractor-trailer truck and would bring dramatic changes in the way energy is produced and consumed in the U.S.

As a result of the advance, Lockheed Martin foresees fusion-power airplanes capable of staying aloft for an entire year without refueling. Longer-term, the company says, the environmentally clean fusion power generated by the reactor could curb air and water pollution and make low-cost energy available to the developing world.

Fusion is considered safer and more efficient than conventional nuclear energy, which is generated not by fusing atoms together but by splitting them apart. The material used to fuel fusion reactions generates nearly 10 million times more energy than the same amount of conventional fossil fuels, according to Reuters.

What do the skeptics say?

"I think it's very overplayed," University of California nuclear engineering professor Dr. Edward Morse, told The Register. "They are being very cagey about divulging details."

Another skeptic, University of Texas physicist Dr. Swadesh M. Mahajan seemed to doubt Lockheed Martin's science.

"Getting net energy from fusion is such a goddamn difficult undertaking," he told Mother Jones. "We know of no materials that would be able to handle anywhere near that amount of heat."

But Dr. Mike Zarnstorff, deputy director for research at the U.S. Department of Energy's Princeton Plasma Physics Laboratory, remains cautiously optimistic.

"We don't know what the promise of this experiment is -- these type of ideas have been explored in the past -- but maybe there are new ideas here that will somehow address the previously found challenges," he told The Huffington Post in an email.

Lockheed said it plans to build and test the first version of the reactor within less than a year, and have a prototype ready in five.

LOCKHEED: We Made A Huge Breakthrough In Nuclear Fusion[color=rgba(0, 0, 0, 0.54902)][size=0.75em]NASA/Solar Dynamics ObservatoryNuclear fusion is the energy that powers stars.

WASHINGTON (Reuters) - Lockheed Martin Corp said on Wednesday it had made a technological breakthrough in developing a power source based on nuclear fusion, and the first reactors, small enough to fit on the back of a truck, could be ready for use in a decade.

Tom McGuire, who heads the project, said he and a small team had been working on fusion energy at Lockheed's secretive Skunk Works for about four years, but were now going public to find potential partners in industry and government for their work.

Initial work demonstrated the feasibility of building a 100-megawatt reactor measuring seven feet by 10 feet, which could fit on the back of a large truck, and is about 10 times smaller than current reactors, McGuire told reporters.

In a statement, the company, the Pentagon's largest supplier, said it would build and test a compact fusion reactor in less than a year, and build a prototype in five years.

In recent years, Lockheed has gotten increasingly involved in a variety of alternate energy projects, including several ocean energy projects, as it looks to offset a decline in U.S. and European military spending.

Lockheed's work on fusion energy could help in developing new power sources amid increasing global conflicts over energy, and as projections show there will be a 40 percent to 50 percent increase in energy use over the next generation, McGuire said.

If it proves feasible, Lockheed's work would mark a key breakthrough in a field that scientists have long eyed as promising, but which has not yet yielded viable power systems. The effort seeks to harness the energy released during nuclear fusion, when atoms combine into more stable forms.

"We can make a big difference on the energy front," McGuire said, noting Lockheed's 60 years of research on nuclear fusion as a potential energy source that is safer and more efficient than current reactors based on nuclear fission.

Lockheed sees the project as part of a comprehensive approach to solving global energy and climate change problems.

Compact nuclear fusion would produce far less waste than coal-powered plants since it would use deuterium-tritium fuel, which can generate nearly 10 million times more energy than the same amount of fossil fuels, the company said.

Ultra-dense deuterium, an isotope of hydrogen, is found in the earth's oceans, and tritium is made from natural lithium deposits.

It said future reactors could use a different fuel and eliminate radioactive waste completely.

McGuire said the company had several patents pending for the work and was looking for partners in academia, industry and among government laboratories to advance the work.

Lockheed said it had shown it could complete a design, build and test it in as little as a year, which should produce an operational reactor in 10 years, McGuire said. A small reactor could power a U.S. Navy warship, and eliminate the need for other fuel sources that pose logistical challenges.

U.S. submarines and aircraft carriers run on nuclear power, but they have large fission reactors on board that have to be replaced on a regular cycle.

"What makes our project really interesting and feasible is that timeline as a potential solution," McGuire said.

Lockheed shares fell 0.6 percent to $175.02 amid a broad market selloff.

觉得三十年内聚变能投入运行就是划时代了，小型化更是不可想象。感觉是国外媒体愚人节的帖子提前发了吧，真有这个东西，什么格局都要重新来过了。黄金也没啥用了。美帝还能称霸几个世纪。趁着还有时间赶快投降说不定还有共荣的机会哈哈

说到新能源，最有前景的还是太阳能热发电，核能成熟多少年了还是造价高、风险大，不值得推广
