 * Single cell thunderstorms are 1e15 Joules (multicell more, superstorm much more!) - use that for comparison, not atomic bomb.
  * 16 million of all types per year, 100K in US, 10% severe
  * find reference!
  * (Convective Available Potential Energy) 1000 to 4000 J/kg
  * 100 kPa -> 1e4 kg/m2, half -> 5e3 kg/m2 tropo, 10x10 km -> 5e11kg *+ CAPE 1500 J/kg = 7.5e14 J
 * Power extraction - compression wave with downstream tension wave, depends on speed of sound
 * Iron magnetics, Kevlar tension member, carbon coating in launch loop rotor
 * Iron magnetics, carbon coating in power loop rotor
 * Pisacane, carbon sputter yield is low at 1000 eV, trace references and software
