In 1942, Philips developed a double-acting hot air engine, which was larger and more powerful than its predecessor, which until now had been developed. When the machine was water cooled, the pressure in the crank room was 10 bar. This pressure was obtained by the installation of an air pump, which was driven by the crankshaft. At a speed of 1500 rev. / Min, the machine had a capacity of 736 watts of 1 HP.

In the 80 J.R.Senft had in the USA the less used Ringbom principle picked up again, and this low temperature Stirling engine built. This machine has been running at a temperature difference of 5 K, and reaches a speed of 300/min. Since the operation and output are still very low, he is convinced that with modern materials the output would improve in the future.
