Tract Homes Solar Generator

Tract homes with mirror roofs focus the sun on a central tower to generate power for community
  [vote for,

The homes roofs are positioned so that for each part of the day a substantial number of roofs are focusing the sun on the tower. The tower has a steam generator that supplies electricity for the community.

The mirrored roofs also have the benefit of keeping the homes cool by reflecting the light and heat away...

The roofs are static to avoid the expense and maintnance problems of tracking machinery.

The big problem would be keeping the mirrors clean. Some kind of sprinkler might work.

Similar concept, except moveable mirrors and no homes [macrumpton, Oct 05 2004, last modified Oct 21 2004]


       The tower would be movable, or there could be multiple towers.

       Morn to night the sun moves almost 180 degrees.   

       Summer to winter the sun moves less say 30 degrees.   

       Focus on a point without moving mirrors if you wish to make steam temperatures is Euclidean mathematically impossible. Focus on a line as with a trough collector will still be difficult and steam only with constant tweaking.   

       Using optimistic 950 to practical 200 watts per meter squared, how much roof area is available in a specially designed tract home even if conversion is very efficient?   

       Show me.

       Obvious solution: Hinge the roof along one edge, and place the house on a turntable. A handy side-effect would be that the house itself would partly follow the sun, sunflower-like. Alternative solution: flocking tract homes.
