I Love to Laugh Mr. Wigg, is said to float because of an excess of "laughing gas", although it is clear that the term is not used in the chemical sense. So-called "laughing gas" (nitrous oxide) was one of the earliest effective anaesthetics developed in the Nineteenth century. it was popularised by dentists, for pain-free tooth extractions, as well as by showground novelty booths. Customers at the booth would be gassed and, as they were recovering from the drugged sleep they often felt euphoric and giggly. Hence the name. A famous 1931 British comedy sketch starring Cicely Courtneidge, called "Laughing Gas", was based on
Reciprocating Chemical Muscle waste gas is vectored into the wings where it is used for circulation-controlled lift augmentation (Coanda effect). Any remaining gas can be used for vectored thrust, but if the gas budgets are correctly designed, there should be no extra gas beyond the circulation control points. The features of the RCM are tailored to the entomopter to conserve energy. Reciprocating Chemical Muscle The reciprocating chemical muscle (RCM) is a mechanism that takes advantage of the superior energy density of chemical reactions. It is a regenerative device that converts chemical energy into motion through a direct noncombustive chemical reaction. RCM is capable
