I've mentioned them here a few times before, but the folks over at Forcefield have yet another amazing homebrew power project. This time they've built — using only “junk” parts and a home workshop — a 17' windmill capable of generating 3.5 kilowatts in relatively low winds.
Speaking of wind, I was really inspired by this story on wind-assisted ships… Instead of using a sail they're using a large inflatable kite, flown at about a half kilometer high where the winds are consistent and powerful, to drag ships around.
As always, I am in a glass house.
But that's OK, because as they say in the song, I do have opaque shower curtains.
