- Editor's Notes
- Been very busy but haven't forgotten your request re: new form of heat engine; will make a preliminary report; "the idea of heating and cooling a fluid in a cylinder full of small pipes and utilizing the expansion by moving a piston requires, as I see it, many more details than this. The final combination will in fact be very much like an air engine." [refers to enclosed sketch, p. 4, and gives detailed technical explanation of how engine would work]; pretty certain I can calculate efficiency of this system on basis of the sketch; think it over and let me know if you see simpler solution; don't forget to inform me about the pyro-magnetic motor and let me see it; am keeping Batchelor's Hall and can come confer with you anytime, though evening is best until business matters are settled. [P.S. "You will note that the accumulators are put in to gain the element of elasticity of air engine by putting in more valves [illegible] made independent and c act like [?] in order to supply pressure when engine valve opened. No opinion yet. In haste, E]
