re: There's a more than a few flaws in his books...
We have been discussing Mars direct as far as I'm concerned. Entering Space is far more speculative by nature. I haven't read much of it so I can't really respond in detail. I'm not sure what his anti-solar power arguement is, but the idea is laughable to me with current launch costs and I've done my own math on that. Refer to the earlier discussion of the cost of getting anything into space compared to it's cost on the ground. As for items 2 and 3 on his list how could you possibly know? Where were lab tests done?
