Gold, copper, value added, and the economy of Chile (with a digression into trains) ; the SpaceShip Two concept of operations, and Tim Pickens’ hybrid rocket motor ; the Karmann Line and the definition of “Outer Space” ― no, “explosive decompression” is not a thing spacemen have to worry about, unlike deep–sea divers ; and intellectual blind spots.

More about the Will of God ; more on means versus ends, and the question of why I see a most instructive contrast between nuclear energy and “renewables”, but a vital conflict between nuclear and fossil fuels ; a brief description of the (non–) problem of nuclear wastes ; and a thumbnail sketch of the potential of space solar (pops ’em like popcorn!).

In which I take a long digression on the significance of energy to women in particular, and then a further one to address the fraught topic of “Nazi rocket scientists”. Some folks find it difficult to accept that the USA employed Wernher von Braun, and I don’t say they’re wrong to feel this way ― but there is some context which desperately begs to be discussed.

This is the first ASFO show to have been archived, and was done by dialing in to the conference bridge (x1088) on the SDF VoIP system, also used for aNONradio OpenVoIP. I spent much of the time discussing the growth in energy use since 1700, why the movement toward a high–energy society is a good thing, and why it has relied up to the present on fossil fuels despite their obvious problems. I end with a cliffhanger, so tune in next time!
