Field notes
The homepage lists 92 build guides across nine parts, from conservation and passive solar design through electricity, wind, water, and biofuels; it also reports 20 calculators. Sample entries include a window-sized air heater and a box-fan blower door, with the latter explicitly described as not a certified airflow test. The hardcover edition is described as still in production, while the guides are stated to be free to read online.
