Flew to TN Wednesday afternoon and then spent hour with semi-retired NASA guy talking a mag-lev transport network for US, plus Free Electron Lasers to power spacecraft to moon and power facilities there. All very cool, seemingly plausible, and forward leaning. Cost estimated for mag-lev network in manner of interstate highway system? A mere 350 billion. Pocket change this week! Thursday is all-day meetings at Oak Ridge National Lab, then flight to Reagan. Friday is long session brief and discussion with a collection of operators from the special forces universe, the kind who purposely don't look military. This group had requested me a while back and a friendly intermediary set it up. Smart bunch. Privilege to participate. Home Friday for the debate.
