...Lesson for Nasa! US Airmail and Aviation
But if everyone could harness solar and wind energy through a single purchase
item, unlike a car that needs gas, or a home that needs electrical power, then

not enough wind and sunlight hit, say, an office building, to meet the
energy demands of that building.
