    Where, oh, where does that carbon come from, pray tell?

    It comes from the air, when the plant grows. Which is where it returns.

    ONLY fossil fuel contributes to global warming, because ONLY fossil fuel adds carbon to the global carbon cycle. Biomass is carbon neutral.

    If you don't stand for something, you'll stand for anything.

      and, granted, certain usages (heavy transport, other than rail, and flight) are not easily converted to other energy sources.

      still, the capture of solar energy - sequestered by photosynthesis in the biomass, converted, with some loss, by APR, then delivered - is still not a screaming solution in and of itself.

      but i guess i'm nearly convinced that it could become an important piece in an overall mosaic solution

      •  If efficiencies continue to rise... (0+ / 0-)

        in hydrocarbon fueled combustion engines, then marginal hydrocarbon energy sources could become a large chunk of the reduced total. Of course, my statement ignores economics to make a point, because as petroleum demand falls, so will the cost, keeping it competitive, unless we tax it to death.

        Add in more mass-transit solutions, like trains, and that could make things even better. Now, if only we can start having "plug-in" parking meters and lots paid by credit or debit account that recharge those plug-in hybrids and all-electric vehicles and we'll have gone a long way.  Add in high-energy lanes for plug-ins and all-electrics that use microwave beamed power or an electrically conductive fifth road wheel and you can extend those ranges even farther without burning hydrocarbons. Add to that high-efficiency solar panels that can be mounted on the roof (even if below a chromatic layer) and you can extend it even farther.  Add to that rapid charge chemical batteries or flywheel batteries and you can recharge a car in minutes instead of hours from any convenience stop, and you can extend the range even further afield.  While we're at it, we might want to use compressed air for adiabatic cooling in cars on hot days instead of a power-hungry refrigeration unit.

        "Four More Months!" And counting... down.
