PBS Nova Documentary "Secrets of the Sun"
Airdate: April 25, 2012
Coronal mass ejection, or C.M.E. It's a wave of billions of tons of electrically charged particles.
Together, they could hit like a cosmic tsunami, delivering a surge of radiation and an electrical spike of trillions of watts, potentially crashing the power grid.
In March, 1989, in Quebec, Canada, that's exactly what happens. One by one, power stations crash, disabled by the overwhelming power surge caused by a C.M.E. wave. In less than two minutes 6,000,000 people are left without power.
NASA's Jim Green finds evidence that an even bigger solar storm hit Earth in 1859, the granddaddy of geomagnetic storms, and that was just 150 years ago.
The massive electrical surge from a C.M.E. wave could overload power lines and melt transformers, blacking out entire cities.
Repair could take weeks, months and even, worse case scenario, the National Academy suggested up to 10 years for a full recovery.
Large transformers take many months to make. Would need a lot of them. Do they have power to make them ?
The documentary suggests, Need to chop wood to keep warm and a gun so we can eat squirrel.
There is only hours of time to take action when a large CME is detected.
***Question: Is there a national plan in the USA to power down the "grid" for some time to protect it from destruction ?
How about communication between NASA and power stations while power is off, Ham radio ?
