Guest blogger Sam Dinkin has a couple pieces at The Space Review today–an interview with Dave Criswell, co-inventor of the Lunar Power System (Bob Waldron, who used to work for me at Rockwell, is the other co-inventor), and an assessment of the global implications for the development of such a system.

I have to confess to being an LPS skeptic, but DoE has wasted a lot more money on a lot less promising things. In any event, the key to making any of these things happen, whatever their technological feasibility level, remains the cost of access to space.
