You may also find that the Earth's mass just keeps pulling the heat away such that it's hard to charge it up too much. But there may be a bigger benefit, which is you will create a syphon which will suck the cold air from the air drop down into the 20' pipes where the cold will then be pulled away by the Earth's heat. In that way there will never be cold air accumulating in the greenhouse. You can always cover the black end of the pipe to see if the temperature of the earth at the bottom of the pipes actually heats up or if it works by pulling away the cold (maybe some of both).
If using the Earth's heat to pull away the cold does the trick then you might want to have the pipe go through solar heated thermal mass like Willow Wonka's lovely trombe wall. That way it will keep pulling at night when heat loss is the worst....that cold air will then just keep getting sucked down the pipes where the cold will get sucked into the earth.

and that doesn't take into account off-street parking dedicated to cars. I haven't done all the work to calculate it, but I'm confident the number would be much higher in my small town. easily over 50%.
in the United States, our built environment makes cars all but required in many places. in that situation, I don't believe it's wrong to be thinking about what sort of car is the least detrimental, but that can distract from more important things. things like minimizing one's own automobile use and supporting changes that make automobiles less dominant and easier to live without.

I am considering purchasing a cheaper model of a wood chipper to put the cheapo mulch through in hopes to get it smaller and easier to work with.
Does anyone have any experience with this or know how to make this happen or if it is worthwhile?
Before we go back into the "no wood chipping" discussion... I live in a residential home that has 0.12 of an acre and have only the mulching in my paths that I want to cover. My goal is to cover my entire back yard with wood chips, to remove weeds from the property, and to focus on adding plants and trees that I want in my yard.

I like the idea of planting trees, and integrating either solar or wind power...would there be a way to optimize it so the trees dont interfere with the wind or the sun?
I guess i'd have to figure out which direction the wind normall blows from, and put the turbine in front of the trees on that side. Same with the panels but in the south. I think this could be doable with some serious planning...and give me two value added things in a single spot.

Maybe you could design that and I could rent it from you... I think you would just need one blade to dig in deeper on the way up. I'm not sure bark has to be removed randomly the the video of doing it manually worked. Maybe one strip up the side would do as well.
