"Peter Van Dresser... built a solar heater here in New Mexico in 1956 or '58. We published his book, Landscape for Humans. One of the greatest forces... has been Harold Hay from California. ...I ...heard him in ’68 at the Solar Energy Conference. I had... a design and... modest success... Harold showed everyone... dead simple methods of doing the same job. He... completely changed my head around on how to attack these problems. ...[W]e’ve worked together a lot since then trying to bring some reforms into the Solar Society."
