    A long time ago, I saw plans in a ham radio magazine (the first issue of Ham Radio Horizons, IIRC, not around anymore) back in 1977 for a small-scale portable windmill that could be built from scrap sheet metal & an alternator from a junk car.

    Even a 1KW unit (roughly the output of the unit in the magazine) would be sufficient to recharge a laptop, several cellphones, and run a couple of lights. In an era of tight energy (see some of Jerome's other diaries) replacing batteries every few years could become a problem though.
