During the early part of the twentieth century the role of the Stirling engine as a "domestic motor"[REF] was gradually taken over by electric motors and small internal combustion engines.
By 1951, the 180/200 W generator set designated MP1002CA (known as the "Bungalow set") was ready for production and an initial batch of 250 was planned, but soon it became clear that they could not be made at a competitive price.
