Note July 12, 2015 - the citations in the June 3 version of the paper were poorly formatted, and two links have changes since posting the above. I have repaired most of the citation format errors, and will post a new version (along with the June 3 version) on Monday July 13. I still have not received the reviews expected on June 25.

Woulda Shoulda Coulda

The deadline for this draft was June 3 midnight. The next morning, I'm already thinking about what I could have included.

Page 7 top left:

It is an accident of history that computers are programmed with text; Inca quipu, Mayan and old world weaving, and Jacquard machine-woven brocades were designed and coded visually and tactually. The read-only memory for the Apollo Guidance Computer was literally a rope of wires hand-woven through magnetic cores[A]. Programs may be created, compiled, and evaluated with other sensibilities; ...

    • - This assumes 100% collection, conversion, storage, and transmission efficiencies. 10% might be possible.

    • - When terrestrial solar advocates bring numbers, bring a calculator,

  • - The uranium bubble is way too small, presumably very inefficient use of existing refined uranium.
    • -. With closed cycle integral fast reactors and complete fuel burnup, very low grade ores can be used, almost no waste.
    • - There are 5e13 metric tons of uranium and 2.3e14 metric tons of thorium in the earth's crust.

    • - At 5E16 J/T, 1TWy=3.16e19J, 632T/1TWy, that is 450e9 TWy, a mere factor of 5 to 1.5 billion larger than 90 to 300 TWy.

  • - The 6e8 TW passing the earth closer than the moon is 26,000 times larger than the "SOLAR" circle shown on the screen.
  • - The 3.8E14 TW emitted by the sun is 16.5 billions times larger.
    • - The 2.3e4 TW circle is 500 pixels wide, so 6e8 TW is 80,000 pixels wide, and 3.8e14 TW is 640 million pixels wide.

    • - Properly done, space collected energy used in space does not rob the biosphere or add heat to the earth.

  • - We must be very very careful - some people believe strongly in industrial-scale terrestrial solar, and resist actual analysis and empirical evidence with slanderous anger.
