THIS SHOWS HOW THE SUN ACTS AS A HUGE SOLAR DYNAMO.
it's rotating and changing magnetic fields induce electrical currents in the plasma in space!  These travel to earth and all over the solar system. they can be used for electric power by magnetohydrodynamic science!! here are links;

OTEC ocean power

OTEC is ocean thermal energy conversion.  It is related to geothermal but can be used on 3/4s of the earth's surface. (much better)  It takes the energy difference of surface water and deep water to create hot and cold places that power a heat engine.  The sun supplies energy to this by heating the ocean saltwater.  Lots of times an ammonia boiler is used but Stirling engines would also work.

this blog is being created as a new blog from the parent site so that it can focus on more general alternative energy topics.  most articles will be free but as the site develops articles will be by subscription. (5 dollars a year per email account) a paypal button will be created for that soon. in the meantime enjoy a free ebook I put on google drive!
