Last night I watched History channel 10-hours "Doomsday 10 Ways the World will End".. the others are far out like Gamma Ray Burst, Black Holes, Rogue Planet, Killer Asteroid, Nuclear War, etc. and I can only feel entertained but when I watched the Solar Storm part. I got alarmed. This has happened before in the 1800s. We are due for another one. And when the Coronal Mass Injection hit us. All power grids will be fried including transformers that will take 2 years to build. In less than 10 months. Half the world populations would die from starvations and riots. But what concerned me the most is its mentioning that nuclear power plants need constant electrical power to cool the nuclear rods. And their backup power only lasts a week. So without power, would all nuclear rods really melt down? The series mentioned 450 nuclear plants would face meltdown. If this really occurred. Would their still be areas anywhere in the world where the radioactive clouds won't reach? (for us lucky few who would survive) This is very horrifying.. what is your take on this and what realistic things must we do to avoid such global catastrophe? Without watching the show, I couldn't have been aware of it. but why are others not seemed to be worried? What follows is some basic about CME and the danger if in case you are not aware of it. http://www.popsci.com/science/article/2011-05/are-we-prepared-catastrophic-solar-storm One of the biggest disasters we face would begin about 18 hours after the sun spit out a 10-billion-ton ball of plasma--something it has done before and is sure to do again. When the ball, a charged cloud of particles called a coronal mass ejection (CME), struck the Earth, electrical currents would spike through the power grid. Transformers would be destroyed. Lights would go out. Food would spoil and--since the entire transportation system would also be shut down--go unrestocked. Within weeks, backup generators at nuclear power plants would have run down, and the electric pumps that supply water to cooling ponds, where radioactive spent fuel rods are stored, would shut off. Multiple meltdowns would ensue. "Imagine 30 Chernobyls across the U.S.," says electrical engineer John Kappenman, an expert on the grid's vulnerability to space weather.
