But Shay you talk about reducing the marginal cost of producing energy to zero as if it is just question of physics. It's not. It's political. You're falling into the exact trap that I worried about way back when I was typing in grey about techies thinking technology will solve the problem (which, fwiw, I don't think is what Eben thinks but he can speak for himself). You're right, dropping more science, physics, information onto people won't change things. What's concealed in your simple dream of a world where the 'marginal cost of producing energy is zero' is a massive revolutionary upheaval that will transform industry, politics and presumably art and culture also. So creating spaces for people to dream about these things and paths for them to put them into action is the project we all agree on, even if we are taking on different roles in signposting the way. There are no shortcuts or simple answers.
