Steorn has completed their first real-time lecture/demo concerning the

Since I'm not a trained electrical engineer I'm not qualified to judge
the accuracy of the technical terminology bandied about, other than to
say that I am aware that many qualified engineers have commented on the
fact that there seems to exist some weird well-documented
characteristics concerning things like "CEMF" and how such effects can
apparently alter how Lorenz law would manifest in the classical/textbook
case.
CEMF is not some "weird" effect. It IS how the Lorenz force law
"manifests" in the classical/textbook case. It's the
counter-electromotive force which appears in a coil when you put a
current through it and it's as common as fleas. Contrary to any claim
that it lets you get free energy out of an electric motor, it's the
reason you *can't*. It is just another name for the manifestation of
the formula
V = -L * dI/dt
and in fact it falls directly out of Maxwell's equation
Del X E = -dB/dt
Any time you try to change the current through an inductor, a voltage is
induced which is proportional to the rate of change in the current times
the inductance. That voltage -- which results in energy being consumed
(or released) by the process -- is proportional to the rate at which
you're pumping energy into the B field of the inductor (or pulling it
back out). And another name for it is CEMF. And, as I said, it's part
of the reason why energy is conserved in motors, which is, in turn, why
Orbo is bogus.
If Sean is claiming that the CEMF is something strange and/or unusual
which Steorn has learned to harness (unlike all those other dunces out
there) ... well, I'd change channels.
Take nothing Sean says at face value, and only believe it if it's
confirmed, in detail, by someone *known* to be honest and competent in
the fields of EE and E&M.
