 In 1940 he began to build insulated Faraday cages , " orgone accumulators , " that he said would concentrate the orgone . The earliest boxes were for laboratory animals . The first human @-@ sized , five @-@ foot @-@ tall box was built in December 1940 , and set up in the basement of his house . Turner writes that it was made of plywood lined with rock wool and sheet iron , and had a chair inside and a small window . The boxes had multiple layers of these materials , which caused the orgone concentration inside the box to be three to five times stronger than in the air , Reich said . Patients were expected to sit inside them naked .
