A Bit Warm

Since 2006, China and France have been working together on the International Thermonuclear Experimental Reactors HL-2M Tokamak, aka 'The Artificial Sun, which is a nuclear fusion reactor which replicates the natural reactions of our own Star.  
Today was the day of the big turn on and it worked and they did create an artificial Sun, actually they created 10 of them because the reactor heated to a temperatures of over 150 million degrees Celsius, ten times hotter than the core of the Sun.
An excited boffin in white overalls with pens in his top pocket said that this is the first step towards 'almost limitless clean energy' which is obviously a good thing but creating a machine that burns at the heat of 10 Suns!!
Nope, can't imagine how that could go horribly wrong.
