sound, crane lifting, elevator, starlight(Earth/eye), cpu, memcell,
some massflow E eqivs, petro/gas/coal frm Cow 240, rad exp [Cow 256],
insolation vs latitude band [Cow 262], human food in [263]
clarify car, human, net primary productivity
breakdown human, grok structure, all of light
wood&dung: 30e18J/yr(1980)[Cow 240], 3.2e7s/yr, so 1e12
hydro: 6.1e18J/yr1980, so 2e11
From [Cow, p238]:
sun into space 3.7 × 1026

From [AJP v60n6 Jun92 pg576]
1 power plant = 109 W
1 person (small) = 1 light bulb = 100 W = 2065 kilocalories/day
1 world = 1013 W (power consumption, solar power not included)
1 solar world = 1.7 × 1017 W (incident solar power, top of earth's atmostphere)
1 sun = 3.8 × 1026 W (total output power)
