Why the hell haven't we opened it? Wouldn't it solve a lot of our energy problems today?,(reply>), Thank you for taking the time to educate me much appreciated! That makes sense because the whole world would be fighting to take claim of an energy source that did not run out for hundreds of years!,(reply>), No it wouldn't solve our energy problems - it's some form of 'dry pile' battery that generates a very tiny electrostatic charge in the nanoampere range - a bit like the charge when you rub a balloon on your hair. Also it's heavy &amp; bulky &amp; wouldn't drive any modern devices. The military did use something similar 30 years ago to create a charge in certain electronics, but it was a specialised application.
