Oh yeah, this is a good idea ...

China plans to test its "artificial sun" on August 15.

It's a super-conducting fusion collider. The Chinese say the plasma discharge will be brief and contained by 5-ft. thick walls and 3-ft. ceilings, all of concrete.

Given the nature of the processes and energies involved, we think the Chinese are skimping a little on the safety barrier. Remember, this is the same China that has huge cracks in the concrete at the just completed Three Gorges Dam project.

You might want to have your bottled water, first aid kit and three or four weeks of canned goods on hand, especially if you live close to the Pacific coast. Just in case.
