Re: tesla's colorado lab

Tesla's problem was insulation. He just didn't have the kind of materials
available
that we have today - hence the seemingly large wire size ('though, the
conductors
were large, anyway; he was processing enormous amounts of power at CS).
And, the
coil in the picture is huge - many tens of feet in diameter; the inductance
would
also have been enormous. Isn't that what we try to acheive in the secondary
with
our coils?
Just my two cents.
Cheers.
