I really enjoyed the interview. Nick you have had an interesting life so far. May it continue with Solarcoin.
I especially liked the part where Socrates and Nick were discussing the evolution of BitCoin vs. SolarCoin.
BitCoin ended up centralizing with miners playing the "red queens game" to have relativistic gains among the remaining players of the game.
SolarCoin does not have this centralization problem, because grants/rewards are given out to the panels in the real world. If you want to get power/energy for yourself, go out and buy a solar panel, and also as a bonus, you will get SolarCoin...
