Om solstorme og klima
By Hedegaard | February 5, 2012
Om faren ved solstorme:
“If you lose electricity, within a matter of days you essentially lose almost everything else,”
Citatet stammer fra den amerikanske forsker, Kappenman. Ifølge ham er solstorme er reel trussel mod det moderne samfund. Udsigterne til problemer tager bl.a. udgangspunkt i tidl. episoder:
“An even more extreme storm in September 1859 caused geomagnetic currents so strong that for days telegraph operators could disconnect their equipment from battery power and send messages solely via the “auroral current” induced in their transmission lines.”
Kappenman har forsøgt at analysere et nutidigt scenarie og Kappenman,
“(…) has consistently found that in a worst-case scenario where a great geomagnetic storm strikes with little forewarning, the excess current in the U.S. power grid could overheat hundreds or thousands of high-voltage transformers, melting crucial components and effectively crippling much of the nation’s generation capacity. Based on current production rates, building replacement transformers would take as long as 4 to 10 years, during which more than a hundred million people would be without centrally provided power(…)”
