Little House

I enjoyed this post about building a very small house.  Not everyone needs large amounts of living space.

I'd be honored. I've always wanted to live in a house with a turret; I just hadn't figured out the best way to put one in. I started with an A-frame house, with an attached tower, and my ideas have been evolving from there.

Though all those power-independence items would get a little costly. Solar roofing tiles and a wind generator would run ~$2k-3k together. The other two items would total ~$4k (those fuel cells are pretty expensive right now). Fortunately, a Tesla disc-based water pump would be a reasonable hobby project, if you had a good workshop available; just run the water through it instead of pumping the water, and attach a generator to the drive shaft. Still ~$200 for raw stock, parts, labor, and machine tool access.

Then again, you can build a wind generator from a pair of hula hoops and some cloth, hung on a pole and attached to a car alternator. Just gotta use the right charging circuit.

How do you build a wind generator from hula hoops and cloth?

I can't find any references for it; they must be buried right now. Anyway: Start with a pole on which you will hang your vertical turbine, two hula hoops, and cloth. Just as with a hanging wind ornament, you sew strips of cloth, binding the hoops together, and each strip has a single twist in it (in the same direction). Next you choose the top hoop, and tie cords/spokes from the rim to the center, so you can hang it on the pole tied to a frictionless bearing. I don't recall whether the bottom hoop is also tied around the pole; I think so.

Anyway, that is your turbine. You then link the turbine to a car alternator (using a gearbox or geared transmission), which provides the current. From there, you add an electronic charging circuit so your batteries receive what they need and no more.
