Baer had been using the trailers for about a year at the time the 1950 article was published. At that time, the principal use for the trailers had been to park one at a particular spot like a general store in a rural location for a day or two.

In order to have the electric units working, the trailer plugged into the store’s electrical connection. Gasoline generators mounted on the trailers furnished 110-V power for demonstrating the gas appliances.

For the comfort of the potential customers, folding chairs were available and coffee was made and served. On hot days, cold Cokes were offered in place of the coffee. And all who stopped by were given a small gift such as a measuring stick.

Sometimes drawings were held to increase the traffic. Visitors wrote down their names and the appliances they were interested in. Later, these cards were used for follow-up.

Everyone Under the Sun The Sheet Metal & Air Conditioning Contractor’s National Association (SMACNA),North-american Heating and Airconditioning Wholesalers Association, Mechanical Contractors of America, Air Conditioning Contractors Association of America, National Funding for the Sheet Metal and Air Conditioning Industry, Solar Energy Industries Association, Air-Conditioning and Refrigeration Institute, and American Supply Association, with the support of the Department of Energy, worked together to draft a series of questions on solar applications of space and domestic water heating.

The questions were for local hvac licensing or registration boards to include on their exams if they so chose, “assuming that basic hvac questions were already a part of local contractor licensing exams,” reported the April 2, 1979 News. The questions were developed from “recognized textbooks and courses on solar heating.” These boards could pick some questions, all of which were thoroughly researched, from the 150 that were developed to include on the exams.
