Amaterasu: "Overunity devices"? What's this about? All the links I find are filled with junk. You know very well we can't have levitation on anything without investing tons and tons of energy in creating magnets? A superconductor is but a dream, for now.
As for money - we will always need it, for there will always be a desire to trade objects of unequal value.
A big problem with the money we have today is that it's worth ten times more to the banks than it is to us. Another is that a lot of nations have given the power to contract and expand the money supply to private institutions, which is just absurd. I could go on, but let's stay positive for now.
Acumen: Even though you started this discussion, you haven't brought much more than ideals to the table. Just saying. How do we get there? What should we focus on?
