Test question 1

The internal coosubtimn engine in the current configuration is the only engine that I remember from high school science class. They covered both the diesel and gasoline engines, how they worked and a brief history. There was no mention of an external coosubtimn engine that I can remember. There is and it predates the internal coosubtimn engine by quite a few years. I thought school was supposed to encourage and stimulate thought and curiosity. How can this be done properly when they don't provide alternatives to currently used and accepted devices. Who knows what somebody might get as an idea to build?Steam proplusion technology may be obsolete; but what about the stirling engine used as a heat pump on a nuclear reactor as a means to capture the lost heat? You can generate 1w of energy off the palm of your hand with a small stirling pump. And it's actually more efficient then a steam turbine.
