<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>It seems that this prediction has not been realized. I think Birkeland was saying that electrons were being acclerated from the surface to the positively charged heliosphere, so we should see a stream of electrons flying from the sun. How ever the solar wind is essentially neutral, that is both positively charged nuclei and negatively charged electrons are in approximately the same ratio. This seems to contradict what Birkeland predicted.</DIV></p><p>We're sitting inside a "current flow" or "discharge" that is taking place between the surface and the heliopshere. Birkeland predicted *both* electrons *and* positively changed ions that would follow those electrons. If you sat there and counted it over time, it may "seem' like a net zero "current flow", but it's not. The whole circuit energy would need to be considered. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>There is no evidence of high energy discharges, if by discharges you mean electrical discharges.</DIV></p><p>You mean except for those million degree coronal loops Birkeland and Alfven both "predicted"?</p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>You have said the coronal loops look like discharges but I do not agree,</DIV></p><p>I don't care.

In such a conductive fluid such as plasma I cannot see how it would be possible to build up a meaningful difference in potential to drive large discharges. </p><p>Posted by origin</DIV></p><p>What causes the solar wind to accelerate in your opinion then? What emrpical test of "magnetic reconnection" would you cite to verify your claim, and please don't hand me that PPPL paper again. We've debunked that one already.</p><p>Magnetic lines lack physical substance. They form as a full continuum, without beginning and without end. They are physically incapable of "reconnecting" so what actual physical process are you claiming is the cause of the heating of the plasma in the solar atmosphere? </p> <div class="Discussion_UserSignature"> It seems to be a natural consequence of our points of view to assume that the whole of space is filled with electrons and flying electric ions of all kinds. - Kristian Birkeland </div>
