Hard to say what the inventor, Catalan, said. But the author, Arcega,
did make some far fetched claims:
"...half of all the electricity in the world is consumed by electric
motors... Improving the energy efficiency of the world’s electric motors
by just one tenth would save enough electricity to run the entire
country of Japan for an entire year [what ever that technically
means]... Now imagine if the technology to make electric motors nearly
twice as efficient were already here."
"He says the prototype motor represents a breakthrough technology that
effectively doubles the power and efficiency of any device that uses a
conventional electric motor."
"By harnessing this ‘near-monopole’ energy, Catalan says an electric
vehicle using a production version of his new motor would travel nearly
twice as far as a conventional motor on the same set of batteries."
I agree that market spin is open to interpretation, but these statements
are pretty clear. And pretty wrong.

We're not talking about academic research here. This is a for-profit
enterprise. They want investors.
Obviously I'm not a company insider or "stakeholder," just a skeptic;
nor am
I an engineer or physicist, so I can't speak to the Halbach related
claims.
However, let's envision one possible scenario.
Suppose you could reduce losses in a motor from (say) 4% to 2%. You've
halved the losses, so you've doubled the efficiency, no?
Well, it all depends on how you define it. If your power input to the
motor
is 100 Watts, the old version produced 96W of output. The new one
produces
98W of output. That's 2.1% higher (2/96) output. Doesn't sound quite
as
impressive as "doubling the efficiency," does it? Which one do you
think a
salesman, or a PR person, or a "journalist" looking for a clickbait
story
that willl "go viral," is going to quote?
