  •  Solar shingles for house roofs (4+ / 0-)

    ...would be another huge breakthrough.  As to other applications, solar can potentially provide significant portions of the energy requirements for many common devices, even when it's well short of being able to provide enough power of itself.  70% conventional/30% solar is way better than 99% conventional 1% solar limited to exotic applications.

      They're neat because they don't destroy the look of a house. But consider all the big box store rooftops first. All the warehouse rooftops, all the shopping malls, all the manufacturing plants.

      Those rooftops are flat. They're ugly. No one looks at them. That means the solar collectors don't have to worry about aesthetics. Plus, they generally have companies with spending capital inside them.

      America should start by filling those rooftops because systems can be built with very cheap concentrators instead of expensive  collectors.

        Leaks have to be patched, toilet vents, chimneys, etc., have to be patched, frisbees and GI Joes w/ parachute have to be retrieved, etc.

          I have no idea, they're too expensive to install!

        •  flexible roof panels being installed all over (0+ / 0-)

          comes as a sheet printed on the same material often used on flat roofs currently...rolled out, glued down, plugged in and gone in ten minutes.

          Low efficiency, 12% maybe.but way easier on a flat roof, no penetrations for hardware, no frame weight, can go on any flat roof without worry for the weight.

          Google something like  flexible solar panels roll roofing and look for you tubes that give links to it.

          Currently done and installed by regular workers, no fancy scientists needed.

          This machine kills Fascists.
