Windplants: Learn About Wind Power

Bill Smith provides a windplant design service and Mike Evans shares information on his more efficient windplant designs in a special windplant section of MOTHER EARTH NEWS No 32.

| March/April 1975

Back around 1931, Marcellus Jacobs (see the Plowboy Interview in MOTHER EARTH NEWS NO. 24) designed a wind-driven generator of electricity. It was good. So good that now — over 40 years later — every commercially successful windplant currently being manufactured anywhere in the world is still more or less a Chinese copy of Jacobs' unit.

Over the decades, of course, many other inventors have tried to improve — or replace — the Jacobs windplant with modifications of the basic unit or completely new designs of their own. Not a single one seems to have had much luck in that endeavor ... so far but that hasn't discouraged a steady stream of new experimenters from trying to beat Marcellus at his own game year after year after year.

Now that a goodly percentage of the earth's human population is finally beginning to realize the finite nature of the planet's fossil fuel reserves and is interested in learning more about wind power, the search for more efficient windplant designs has suddenly grown even more intense ... and a sampling of the latest work in the field is shown on the pages that follow.

A Windplant Design Service

We have a service to offer anyone building a windplant: complete design of the blades (with templates) plus generator, transmission, and tower strength considerations. Just provide the following information:



[1] Average power needed, in watts

[2] Average wind at site, in mph
