  •  I too thought that at least solar would be a (3+ / 0-)

    regular part of the jobs I'd be bidding on. Back in the 80's installing roof panels and holdings tanks was picking up..then it just sort of ended.
    There were problems with freezing in the winter, which caused some people to have second thoughts, but re-circulation pumps were being introduced to fix that, and even ingenious convection systems that did away with the need to power the re-circulation.

    Reagan really did screw things up when he pulled those panels off the White house. It seemed to make solar a DFH thing and therefore a bad thing.

    Even better is the solar electric panel work. It was small time at first on  RV's that sit for long times & needed their batteries charged regularly. That was good for a few jobs.
    I thought that that would lead to solar electics for residential, but the jobs are expensive and few & far between.

    Hope this Energy report is the future. We need these kind of jobs & clean energy that can't be outsourced. It'll be on every roof top as a regular part of home building..at least in this old carpenters dream.

    •  stored solar (3+ / 0-)

      stored solar cracks water to hydrogen and oxygen for storage w/ only the sun. coupled to a breakthroughfuel cell which replaces the platinum as cathode and replaces it with carbon nantube technology reducing costs 25 percent , and have improved output.

       Stand alone power from the sun , night or day

      •  Thx for the links. Great news. Can you imagine (0+ / 0-)

        producing your own fuel for a vehicle out of your back yard? Wow.
         Storage is a tough one, yet  there are many devices that, today don't need nearly as much electricity to run. Your computer has to convert 110 AC transformed to what.. 5-12 volts DC. Phones; 1/2 my hand held drills are DC. Many households will be to re-tooling there kitchens [lol] with appliances that don't need 110 AC.
        Not having to convert will save a lot too.

        It's the future for sure. :)

        1) Using energy to crack hydrogen for storage is one of the least efficient and most expensive (round-trip) systems for energy storage possible.  The cheapest (at present day) is pumped hydro, followed by compressed air and batteries (lead-acid, molten salt, and a variety of flow batteries), etc.  Hydrogen is at the bottom of the list by a large margin.  The most efficient is batteries, followed by hydro, followed by compressed air, followed by hydrogen.

        2) The "breakthrough" fuel cell research is for PEMFCs, not SOFCs like which are used on the grid, and isn't nearly as big of a "breakthrough" as has been portrayed by the media (I can go into why if you'd like).  It's been hyped to death.

      •  Doesnt hydrogen run into the 2nd law of (0+ / 0-)

        thermodynamics?

    •  The military is ALREADY using solar (1+ / 0-)

      to stop the killing of troops moving fuel.
