Remove the limit and tie currency creation to its velocity. As more people decide to transact in it do what helicopter ben suggested and randomly distribute the new currency into clients.

I'll just point out that, in your hilariously ill-conceived joke of a system here, one would be able to create "energy credits" by trading ripples back and forth between yourself.

This is the way that the dollar works right now. The real problem is that the new units are given to banks and wall street. Ben had a good idea when he suggested dropping currency from a helicopter.
