The power of the sun in the palm of my hand

So, China's going to build the sun! And apparently other scientists around the world are building "similar devices". (via Slashdot)

Scientists believe that deuterium can be extracted from the sea and an enormous amount of energy can be obtained from a deuterium-tritium fusion reaction under huge temperatures of 100 million degrees Celsius. After nuclear fusion, the deuterium extracted from one liter of sea water will produce energy equivalent to 300 liters of gasoline.

If a device is developed that can withstand temperatures as high as 100 million Celsius degrees and control a deuterium-tritium reaction, it will be as though an "artificial sun" had been created able to supply infinite, clean energy for human beings.

I guess we didn't learn anything from Spider-Man 2.
