Thing is, this is the first time they have generated more power than it took to create. A miniscule amount but a + voltage of any form proves the science is sound. Give it 20 years, that building sized generator making milliivolts of postive voltage, could become a table sized generator capable of powering a town for almost nothing. Much like the first building sized computers became today's superphones. I'm excited for the world, one more thing I can check off the list of "Things I want to live to see"..(Getting old)...lol
