"Deal" Since it cost a lot to win And even more to lose You and me bound to spend some time Wondering what to choose ...Don't you let that deal go down I've been gambling here abouts for ten good solid years If I told you all that went down it would burn off both your ears ...Don't you let that deal go down Since you poured the wine for me And tightened up my shoes I hate to leave you sitting there Composing lonesome blues Don't you let that deal go down

The movement of magnetic fields around a conductor, i.e., a wire or pipe, induces an electric current. The longer the wire, the greater the amplification. The current induced is akin to DC (direct current), which the electrical system poorly tolerates. Our grid is based on AC. The excess current can cause voltage collapse, or worse, cause permanent damage to large transformers. - Potential mechanisms of power grid 'problems' Geomagnetic storms Geomagnetic storms are due to coronal mass ejections (CMEs)—massive eruptions of plasma expelled from the sun’s corona. Plasma is the fourth fundamental state of matter, consisting of free electrons and positively charged ions. The sun, like all stars, is plasma. Coronal mass ejections often occur with solar flares, but each can also take place in the absence of the other. The latter emits radiation in all bands of the electromagnetic spectrum (e.g., white light, ultraviolet light, X-rays, and gamma rays) and unlike CMEs, affect little more than radio communications. CME’s take several days to reach the Earth. The radiation generated by solar flares on the other hand arrives in 8 min. Coronal mass ejections carry an intense magnetic field. If a storm enters the earth’s magnetosphere, it causes rapid changes in the configuration of the earth’s magnetic field. Electric current is generated in the magnetosphere and ionosphere, generating electromagnetic fields at ground level. The movement of magnetic fields around a conductor, i.e., a wire or pipe, induces an electric current. The longer the wire, the greater the amplification. The current induced is akin to DC (direct current), which the electrical system poorly tolerates. Our grid is based on AC. The excess current can cause voltage collapse, or worse, cause permanent damage to large transformers.
I was at an infrastructure security conference a few years back. At lunch around this big round hotel table we were discussing threats … including EMP. The last guy to settle to the table was one of the speakers … the FEMA head for our state. He didn’t join the discussion. After about ten minutes of him wolfing down the free chow, I directly asked him what was FEMAs plan and policy on EMP? Everyone got quiet to hear the plan. He looked quizzically back at me with some mayo on the corner of his mouth and said “What’s EMP? He made a quick exit to stage left after everyone dropped their jaws on the table at our tax dollars being directly wasted right in front of our eyes. It was pretty clear to most that we’re all on our own anyway, but that incident was more directly instructive than anything at the conference.
" . . . And we're here to help." Let's see, where's that 'Next Please' button. Where'd we put that darn button, you see it over there Vern?...
Im not sure I understand your argument. In 1870, 70-80 percent of people in the US were employed in agriculture. This was true subsistence. Now its about 2 percent in agriculture. What did all those people do? The 68-78: They went into other lines of work.
We need to protect our transformers against a Carrington Event from the Sun and EMP attacks from rogue nations. From what I understand, it is done with circuit breakers placed at specific intervals along a line. This includes railroad tracks which can transmit EMP's as well as power lines. But, this could be avoided in the long run if every home was energy independent, producing its own electricity and storing them in batteries overnight. It's still too expensive to be adopted mainstream, but we'll be there in a few years.
