"CME" Coronal Mass Ejection Vs. EMP

Posted on Friday, October 03, 2014 12:08 PM

Greetings & Welcome Back Everyone!

Today and as promised over a week ago, I will look at "CME" (coronal mass ejections) then compare to EMP (electromagnetic pulse).

I quote the following from Wikipedia (link = http://en.wikipedia.org/wiki/Coronal_mass_ejection ):

" Description[edit]


Coronal mass ejections release huge quantities of matter and electromagnetic radiation into space above the sun's surface, either near the corona (sometimes called a solar prominence), or farther into the planet system, or beyond (interplanetary CME). The ejected material is a plasma consisting primarily of electrons and protons.



Recent scientific research has shown that the phenomenon of magnetic re connection is responsible for CME and solar flares. Magnetic re connection is the name given to the rearrangement of magnetic field lines when two oppositely directed magnetic fields are brought together. This rearrangement is accompanied with a sudden release of energy stored in the original oppositely directed fields.

On the sun, magnetic re connection may happen on solar arcades—a series of closely occurring loops of magnetic lines of force. These lines of force quickly reconnect into a low arcade of loops, leaving a helix of magnetic field unconnected to the rest of the arcade. The sudden release of energy in this re connection causes the solar flare. The unconnected magnetic helical field and the material that it contains may violently expand outwards forming a CME. This also explains why CMEs and solar flares typically erupt from what are known as the active regions on the sun where magnetic fields are much stronger on average.


Impact on Earth[edit]



Humans at high altitudes, as in airplanes or space stations, risk exposure to relatively intense cosmic rays. Cosmic rays are potentially lethal in high quantities. The energy absorbed by astronauts is not reduced by a typical spacecraft shield design and, if any protection is provided, it would result from changes in the microscopic in homogeneity of the energy absorption events."

You will notice after reading above Wikipedia description, CME or coronal mass ejection(s) or no where near as disruptive as EMP (electromagnetic pulses) which (EMP) can wipe out the entire planet in a "Carrington Event" (size). I think -and as confirmed by this article- minor radio static along with minor power disruption - more of an annoyance- occurs with CMEs; certainly not as threatening as large EMPs.

Again, with PPP EVs (Portable Power Plant Electric Vehicles) properly shielded at point of manufacture for EMP, nations supplying their national grids with PPP EVs will be unaffected by EMPs even a "Carrington Event" sized EMP. PPP EVs would not have to be protected from CME events as they pose no threat.

I realize this article today is short, but I think this is all that is necessary. Reader of this article can find more information by exploring:
