"illuminate 10 km area orbiting 900 km high... each pass extends energy generation 15 - 20 min around dawn or dusk when demand greatest... high enough servicing multiple solar farms on same orbit... hexagonal reflectors, sides 250 m, 3 tonnes, currently cost few thousand dollars/ kg to launch (if reduced to few hundred dollars/ kilo, reflectors viable within few years)... operate for 20 to 30 years... illumination levels would last only few minutes per reflector and not exceed overcast day level"
