	Mostly:
	Not.  Modern Solid State ignitions are different, have been for
	decades.  The usual points n coil arrangement is patented by
	Kettering, tho there are roots in Tesla coil.

	Name One.

	(hint:
	There are and were many steam turbines, of different designs.
	Tesla was the last of the major single inventors to tackle
	the steam turbine, and never matched the other designs
	efficiencies...)

	Name one Tesla involvement, other than stray popular press
	articles.

	Do they?
	(hint:
	lots of people invented fluid meters before and after Tesla.)

	Many people worked on eddy current drives (I'm Assuming that's
	the reference) and MANY cars don't use one in the speedo.
