Water conservation isn’t as crucial in the Midwest as in other parts of the world, but it still costs money to buy water, and it costs money to get rid of it.  Here’s the basic layout that I’d like to achieve:

1. Collection: Precipitation (on the exterior of the canopy) and condensation (on the interior of the canopy) collects in gutters around the perimeter of the dome, where it’s directed to holding tanks.

2. Usage: The water is pumped, filtered, and integrated into the domestic water supply.

3. Disposal: After being collected in a graywater holding tank, the water is distributed through a series of planters, where it’s filtered and consumed by vegetation.




  1. It’s just crazy enough to work….

  2. Light+Moisture+Air=Mildew. Better find a way to control mold and mildew without using nasty chemical cleaners.

  3. Good point. I’m hoping to integrate some ventilation techniques commonly used in greenhouses. Still researching…

  4. so if i saw this sketch in a magazine (and it was sketched my someone that wasnt my brother) id say “ok mr fancy green pants, woop dee doo. you can water your plants while you do jumping jacks.” isnt there a better use for all that water?

  5. Haha. What do you suggest? I’d love to cycle it back into the domestic water supply, but then filtration gets really complicated.

  6. Just found your site mentioned in this weeks “Tiny House Living”. I’m interested in your concept. For the geodesic dome/shelter roof I have a couple of observations/thoughts.
    1) I worked for a company that sold green houses. One of the problems with simple plastic sheets or panels is condensation will drip off them if their angle is less than about 23 (pulling from memory here so it could be a couple of degrees off) degrees from horizontal. So any condensation on the inside of a bubble/dome will fall straight down from the center onto the top of your cubes.

    2) to deal with this in our hoop style greenhouses that are covered we would put a second layer on, attach the edges, and inflate the space in between with a small blower. That increased insulation and tended to stop a lot of condensation as well as adding to the rigidity of the structure.

    3) If you use poly-style sheeting or rigid plastic panels, you may want to consider the UV resistance of the materials. The plastic used on commercial greenhouses is treated at the factory for a resistance lifespan of a few years. I have seen that some solid panels are NOT treated and they disintegrate within a year or two.

    These thoughts are just for your consideration. I am really interested in your concept and wish you the best. I’m looking forward to following your blog!!

    • Wow, thanks for the great comments. I’ve been wrestling with all of those issues, to no avail (yet). I’d prefer to avoid plastic completely, but that doesn’t leave me with a lot of options for light, view, etc. Glass is out of the question at this point. Currently, I’m considering some sort of tensile structure, with clear plastic on the faces that get sun, with waxed canvas everywhere else. I’ll definitely have to address the condensation issue. Since I have my hands full with the “pod” right now, the canopy will have to go on the back burner. Let me know if you have any more thoughts. Thanks!
