The idea is that you could orientate this with the sloping section facing North in the Southern Hemisphere and South in the Northern Hemisphere in order to maximise sunlight input. It could be used as a passive solar dryer during the warmer months and greenhouse over the cooler months.


The shadecloth can be rolled down over the structure and anchored at the ground for the increasingly common hot days during the cooler months to lower the inside temperature and reduce sunlight if needed. A doorway could be built on one end for entry and also used as an air vent for temperature control OR separate air vents on the roof could be made for temperature control.


The CharEarthBricks can be made with a Chinese manual brickmaker found on, also mentioned on the 'Permachar WIcking Module (PWM)' page. The CEB wall would absorb some of the solar heat during the day and release it into the structure space at night time.


The PolyPIU is double glazed polycarbonate sheet/panel with an air gap for insulation. These are UV resistant and allow sunlight to enter the structure for heating and photosynthesis. I imagine they are also giant hailstone proof, which is an important feature for climate disruption. Since the design is modular, if one or more panels were destroyed they could be pulled out and replaced with a new one(s).


The frame could be wooden or steel. The structure should be wind proof, if built well.


The height of the rectangular box could be 2.5 metres and could be built as long as needed.

Polycarbonate panels should be hailstone proof. Alternatively, if hailstones are definitely no problem, ClearVue glass panels with embedded PV cells or Panasonic Perovskite PV glass panels - no rooftop solar PV panel(s) needed and could connect directly to the power bank. There's also the issue of cleaning the glass panels if dust is a problem and besides, possibly overkill for the power requirements.


Heating overnight
- Boulder Biochar Barrel (BBB) (modded)
    - oil drum on its side
    - 2 modded kegs for retorts which slide in via the oven door
    - oven door and air vents at front end
    - chimney-> outside the greenhouse
    - biochar concrete poured around the barrel in a block for thermal mass which heats up and slowly releases the heat overnight +
    - heat exchanger at end of barrel for additional cogen (if the sun aint shining and the battery runs out - although, could have a couple of extra battery modules charged up when there is sunshine for backup, assuming an Airbase Duo/Quad is used)-> thermoacoustic Stirling Engine->Airbase duo/quad power bank (Kickstarter)->power to LED lights (at night) and fans (during the day if heat needs to be removed from the greenhouse)
        - runs quiet: heat->sound (acoustical resonance)->electricity->power bank
    - output of BBB: heat, electricity and Biochar!


Not the cheapest greenhouse around - maybe one for those pesky Martians (or a wealthy desert dweller). But don't get me wrong - this is just the whole suite of potential tech (and there's more). Modules/components of this design could be integrated into existing or new greenhouses. Very scalable too!

Note NASA is suggesting that electricity could be produced from natural gas in combination with the TASE to power and heat homes. They also say the TASE could use any heat source. So, as referenced on the 'CharGen' page, a TLUD could be used, or in the case of the 'Greenerhouse', a Boulder Biochar Barrel with heat exchanger.
