    has anyone here considered solario? solario is disrupting the global energy industry by combining a patented, 3.8 times more efficient solar technology with the power of blockchain technology. as a result, we are able to deliver clean energy 24/7 to any place in the world at a price so low that it feels like free energy. please visit http://bit.ly/solariomix for more details.

    Could anyone explain why the electrons move upward, towards the negative side? You'd expect them to move to the positive holes downward as they are attracted? Also, how can a hole move? I assume it are ''holes'' on the shell of the atoms, but how does that move around? Thanks

    Still not clear on the middle layer. What happens when all the atoms have no more electrons? Where do the new electrons come from? The sun only knocks the electrons free correct? Then what happens to the atoms? Plasma? lol
