Born in 1952, educated in Edinburgh and Cambridge. I have lived off-grid on the remote Scoraig peninsula in the Scottish Highlands since the mid 1970s. I have designed and built a lot of wind turbines, and also teach courses and write books so that others can learn how.
I am still very active building, installing and maintaining wind, hydro and solar systems for neighbours and other clients.
A number of organisations around the world have adopted my designs and teach courses themselves or build wind turbines. (http://www.windmepowerment.org) I spend a lot of time helping people with their projects and answering questions over the internet. I rely on sales of my books for income but to a large extent my work has become "public domain" or "open source" which is great so long as I continue to make some kind of income.
