Quote: A little more than midway up the THEMIS line, magnetic fields
erupted, "releasing about 1015 Joules of energy," says Angelopoulos. "For
comparison, that's about as much energy as a magnitude 5 earthquake."


err I don't think so.

Perhaps Angelopoulos means magnitude 5 earthquakes measured
on the bathroom scale rather than the Richter scale.

Was that one thousand fifteen Joules or ten raised to the fifteenth power
Joules? I don't trust websites to display such things as superscript text
correctly.

Thanks for the responses guys, but I was not after the
"1015" print-press faux-pas. This here caught my eye
though. In #1 link above it says:

Now, if the Solar wind condition can interfere with the
earth's power grid, it is not a far jump to imagine & ask
"Can this be managed and harnessed to become a
power source"?
Anybody any idea about such research attempts?...
in particular at the Fairbanks Uni in Alaska?
Thanks, hanson

Yeah, it's going to be used for an electric tractor.

Work out the energy involved and see whether it would even be worth it.
