The state of solar panel technology (especially thermal) is stuck where it was 30 years ago because the government is subsidizing projects using that old technology rather than investing in research into new more efficient was to capture solar energy. Here in Florida we have a glaring example of how much of our tax dollars the government can waste while making a select group rich. This solar project will never produce the energy it is suppose to.

But that’s OK because the "green" energy traders will make millions off it and so will FPL Group from tax credits.
And when a hurricane or hail storm wrecks the glass collectors, guess who will fund rebuilding it all over again.
