from last bread:
Can't think of the name of it now
but California bought them for solar power
they are reflective discs?
with a central pole / collection power?
uses light to heat water?
anyway
they set up a huge field of these
and then soon later
took them down
IMO
this is the best kind of solar generation
not the panels
