Richard -
I show how I measured the overall efficiency of one of my coils in the
T.C.C.Guide. The efficiency was 56% and agreed closely with the JHCTES
program and the efficiency graph that I show in the Tesla Coil Notebook.
Some day you may want to review this information and maybe even try the test.
To have a test, computer program, and graph agree so closely is ,I believe,
a step foward in the right direction for Tesla coil engineering. I admit a
lot more testing and work is required to make these three completely
independent sources of data agree more accurately with real world coils.
Hopefully coilers in the future will spend more time and effort on this part
of coiling.
