Incremental list

What are the major themes and issues with solar power?

  • Intermittent
    • Energy storage
  • Cloud cover
  • Materials availability
  • Land use requirements

  • \(E = \sigma T^4\rightarrow T=5777\) K
  • Distribution
    • 7% ultraviolet (UV)
    • 47% visible
    • 46% infrared (IR)
  • Atmospheric losses
    • reflection
    • absorption: O\(_3\), H\(_2\)O, \(O_2\), CO\(_2\)
    • Rayleigh scattering: molecules \(d\ll\lambda\)
    • Mie scattering: particles (pollution) \(d\gg\lambda\)

  • If there were no false positives and you tested positive, you’d have it 100%
  • Consider 80 people
    • 1 has COVID
    • 79 don’t
    • positive tests:
      • 1 that has COVID
      • 79 * 5% = 3.95 who don’t
    • chances of having COVID given the positive test = 1/(1+3.95) ≈ 1/5 = 20%
  • Only 1/80 have it, but the test says 5/80 do.
  • The question is, given a positive test what are the chances of having COVID?
    • The “base rate” is 5, not 80, and the answer is 1/5 not 1/80.

Equations

Inline equation \(f(x) = \beta x^2\) example; single line equations below: \[P(C|+)P(+) = P(+|C)P(C)\] \[P(C|+) = \frac{P(+|C)P(C)}{P(+)}\] \[P(C|+) = \frac{(1)(1/80)}{\underbrace{1/80}_{\mbox{+ test, have COVID}} + \underbrace{0.05(79/80)}_{\mbox{+ test, no COVID}}} = 20.2\%\]

  • Questions?
    • where to get the land?
    • does the wind blow well there?
    • how far away is the power destination?
    • compare the copper (or some other relevant material) to the annual world production and/or known resource.
    • how long do they last?
    • can the blades be recycled, landfilled?
    • affect on birds, noise, neighbors
