    Let's see if science is obsolete.

    Title: Methodologies for carbon capture and CO2 reduction within national domains and marine environments.

    Part I - Generator in a Greenhouse (GENGH)

    A methodology for producing stable sustainable electrical power into
    the future. Move the CO2 from the smokestack/tailpipe to the greenhouse. Tricky,
    I know. Clarkson tried and failed.

    At the time of writing there are no viable large scale CCS or carbon capture storage
    schemes anywhere on the planet. Well there is a serious proposal now.

    It is envisaged there will be set of greenhouses (1km sq each) which each hold generators with a
    base loading of 4 mega watt operating 24hours-365days. These might reach to 8 meg per sq km
    eventually. Is the capital cost/return better than PV or windmills? Yes. This process also
    will extract more energy per sq meter than PV or windmills? Yes. It will be of a lower cost.
    Yes, after all its only glass, not those expensive photovoltaics. A gas tight greenhouse
    should be a much cheaper to build.

    In a greenhouse that is gas tight CO2, H20, water and heat are trapped
    within its confines. It is an artificial environment that naturally
    encourages plants to do their thing. This technique is ideal for desert
    regions because of the water control element. Brownfields, contaminated
    sites could be cleansed, with the correct ash cleaning, etc. These can be wandering
    structures. You could greenify a desert or clean a site of toxins.

    Temperature control - fundamental. (HEP)
    The first level of thermal control is insulation. Prevent heat escaping until
    you want it to escape or be stored in the ground.
    A set of heat exchange pipeworks (HEP) are placed into the ground.
    In cooling mode (summer) these carry warm/hot water to store the heat into the colder ground.
    In heating mode (winter) these carry cold water to extract the stored heat.
    So cooling at daily highs and warming at nightly lows is possible. And 1 km of ground
    and water provides a lot of thermal reserve. Extra cooling facilities maybe needed.

    The nature or type of HEP used depends if it is a permanent installation or not.
    The ability and type of cooling engaged depends on the GH's location. Heat transmission
    pipes can be placed permanently underground or not. This can be done in phases.
    These pipes need to coupled with heat exchange units. These are fridges or heatpumps to you and me
    that use gasses trapped in pipes to move heat energy about. Change/reverse the action of the fridge
    when you need to heat or cool the GH.

    Speed of growth - You can almost see it grow.
    This is a description given to some plants seen in warm jungle conditions.
    Each GH should be producing the correct amount of greenery or more (redundancy/contingency)
    to soak up its daily CO2 load for national grid needs. With luck you really could see them grow,
    as the CO2 level will be higher than any open air jungle.

    No precondition on the plant type, apart from avoiding genetically modified plants.
    Since most plants will have not experienced a environment like this,
    we do not know which will respond well. All manner of variations will need to be tested.

    One of the GENGH sub functions will be as plant nursery. That provides a
    stream of maturing plants to replace those just harvested. It just an efficient use of space, iinit.

    Photosynthetic efficiency (dark versus light reactions)
    This is not a completely answered question. There is some real science to be done.

    The photosynthetic process has a light driven reaction and a dark or thermally driven
    reaction. If a plant is above a critical temperature (9c?) it will photosynthesise.
    If it is below it, it won't. No matter how much water CO2 and light you give it.
    The exact energy contribution of each reaction mode is not known.

    Light (daylight) is not the usually limiting factor to plant growth,
    but warmth, water, CO2 and nutrients are. If you increase the warmth an
