Thank you for sharing this, Frederick. It is the most innovative idea I have yet seen for emancipating ourselves from the grim logic of money as zero-sum arithmetic (which is essentially a monopoly game where the rich get steadily richer, the poor get poorer, until the top .01 percent own everything and the rest of us, nothing at all, and are hopelessly in debt to the “winners” for our houses and hotels!)
How to go about effecting a transition to a solar energy-based currency is the big challenge, of course, since those with a vested interest in the dysfunctional status quo also have the power to resist changing it! Perhaps we could start small, however, by disconnecting from the monopoly game in whatever ways we can—by growing gardens, growing community, and growing awareness.
