*1.5kg/kWhr at the 70kW scale - [https://www.rotarykilnfactory.com/electric-heating-rotary-kiln/]. Note: data jump from 50-70kw is dubious here.
*300kWhr/day from small 50kW array of solar gets us to 450 lb of cement per day - or 2 yards of solar concrete and enough for 1 house a week.
*24 person operation (50 houses/year) can go solar concrete with a 50kW PV array - rooftop of a 5000 sf workshop. 
*Kiln is $15k [https://www.rotarykilnfactory.com/how-much-is-a-rotary-kiln/]
