Technology has immortality, cures for the worlds devastating diseases, quantum computing and a host of other science fiction notions in its grasp. Current trends in a number of areas indicate that over the next 10 years many of these technologies will come to fruition. "The Next 10 Years" tracks the trends that will transform our everyday lives in almost unimaginable ways.

Fusion, the reaction that produces the sun’s energy, is thought to have enormous potential for future power generation because fusion plant operation produces no emissions, fuel sources are potentially abundant, and it produces relatively little (and short-lived) radioactive waste. But it still faces great hurdles.

“There’s been a lot of progress,” says physicist Earl Marmar, division head of the Alcator Project at the MIT Plasma Science and Fusion Center (PSFC). “We’re learning a lot more about the details of how these things work.”

The Alcator C-Mod reactor, in operation since 1993, has the highest magnetic field and the highest plasma pressure of any fusion reactor in the world, and is the largest fusion reactor operated by any university.

One of the most vexing issues facing those trying to construct a fusion plant that produces more power than it consumes (something never achieved yet experimentally) is how to propel the hot plasma (an electrically charged gas) around inside the donut-shaped reactor chamber. This is necessary to keep it from losing its heat of millions of degrees to the cooler vessel walls. Now, the MIT scientists think they may have found a way.
