News Round Up: Ludwig Von Mises, Glenn Beck and Sarah Palin | motorcitytimes.com
"A rather serious problem, which seems largely to have been ignored by those urging a race to build windmills and solar panels, is the fact that the wind does not always blow, nor does the sun always shine. And as yet there is no large-scale economical method of storing electricity for later use. This would seem to imply a need to retain the present system of power production alongside the new system that is to be based on wind and sun, or else to grow accustomed to protracted periods without power. Or is it the case perhaps that this problem is to be taken as an opportunity for even greater gains in employment in connection with wind and solar power? These might be achieved if, in all those times when the wind does not blow or the sun does not shine, human beings were employed in rotating copper-clad generator shafts, in a manner similar to that of rotating a grindstone in a gristmill, only in the presence of surrounding magnets, so that electricity could be produced by the rotation. (I don’t know how much, if any, electricity might actually be produced in this way. But it would provide at least the appearance of employment in the attempt, which is all that many other “stimulus” programs accomplish.) (emphasis added)"
