今天在Physorg上看到一则新闻《Irish company challenges scientists to test ‘free energy’ technology》，说一个爱尔兰公司发明了一种可以无限产生能源的装置，这个装置里面有一个特殊磁场，而这个磁场竟然不是保守场——从某点出发再回到该点，磁通变化不为零！

这个听起来有点神呼其神了，观望之……

An Irish company threw down the gauntlet on Friday to the worldwide scientific community to test a technology it has developed that it claims produces free energy.

The company, Steorn (http://www.steorn.net), says its discovery is based on the interaction of magnetic fields and allows the production of clean, free and constant energy — a concept that challenges one of the basic rules of physics.

It claims the technology can be used to supply energy for virtually all devices, from mobile phones to cars.

Steorn issued its challenge through an advertisement in the Economist magazine this week quoting Ireland’s Nobel prize-winning author George Bernard Shaw who said that "all great truths begin as blasphemies".

Sean McCarthy, Steorn’s chief executive officer, said they had issued the challenge for 12 physicists to rigorously test the technology so it can be developed.

"What we have developed is a way to construct magnetic fields so that when you travel round the magnetic fields, starting and stopping at the same position, you have gained energy," McCarthy said.
