China's Radical New Space Drive

Chinese scientists have been working on a new, propellantless propulsion technology for spacecraft. Although the trust produced isn't enough to launch your cellphone off the desk, it could revolutionize the way satellites move around in space.

The work is not without controversy. It seems that as soon as a paper was published by a British scientist on his efforts in this field, it was instantly attacked by many who dismissed it out of hand. Then a Chinese scientist took up the cause and achieved measurable results. 72 grams of trust. Not much, but in space, constant trust adds up.

Here's a link to the article in Wired about this and here's a link to the Chinese paper. I hope you read Chinese.
