Unfortunately, much of the response was of the sort 'OBOY, we can put a BOMB in it and BLOW ships up!'. I think Tesla was a little disappointed that this was perceived as the most significant aspect of this type of technology. Another one of his strange toys was a compressed air operated 'tapping' or vibrating device which he demonstrated could be used to build up a resonant wave in buildings to the point that they could be demolished. During one of his experiments with this device on a piling in the basement of one building the surrounding buildings began to build up waves first, before Tesla realized he was having any effect as the building he was in had not started to react yet. He was quite surprised when some of the local gendarmes burst in just as the building he was in did start to react, as he had just noticed these effects himself moments ago. We can credit Tesla with AT LEAST the following inventions: 1. A.C. motors, generators, transmission systems 2. Radio transmission 3. Fluorescent Lighting and the Neon Sign 4. First radio controlled devices And perhaps he should be credited with others, such as possibly the discovery of X-Rays (not by that name however) , or perhaps the artificial generation of X-Rays. And, I'm sure there are others. > ...I have always wondered what he may have >written down (diagrams, or messages, or ?). Since he no doubt >knew of their presence, I bet he pulled some good tricks on them. Some of his writings are quite readable. He published several articles in Electrical Experimenter in the 1910-1920 era, in a column called 'My Inventions'. BY the way, there is a unit of measurment called the 'Tesla' but I forgot for the moment what it's for. Anyone remember? Keith Doyle # {ucbvax,ihnp4,decvax}!trwrb!cadovax!keithd
