" I think that computers today allow us one last opportunity to provide something like a level playingfield in America."
- William Gibson

Rooftop Windmill  
  Renewable energy source for the home.  

Sometimes a man has a windmill on his roof for light and heat; then, the harder the wintry blasts may blow the brighter and warmer becomes the house, the current passing through a storage battery to make it more steady.
From A Journey In Other Worlds, by John Jacob Astor IV.
Published by Unknown in 1894
