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? |

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. |
