It's hard to tell fact from fiction these days especially on April 1st.

The fact that it involved Scotland made it very believable - kind of thing the SNP and their green allies are likely to do..

Our 15 year old washing machine has one, bit of torque ripple at lower speeds. Like an upmarket stepper motor.

Wow, bit of a blast from the past for me. There was a research group in my department at University of Leeds developing these back in the early 90s.

Feels a bit of a stretch to claim that lack of magnets is a breakthrough, though. Bear in mind that regular induction motors don't need permanent magnets. Even regular DC motors can have a wound field core (although does then require slip rings and brushes). Variable speed drives for both these motor types are quite mature technology, too.

Yes, I believed it at first, but there are less likely things !

I wonder if this will increase with EV drivers not realising their cars may be so quiet that cyclists / horse riders / walkers / etc don't hear the approaching vehicle?

EVs may be part of the solution to global warming, but that is not necessarily the reason to run one. They are IMHO just better than fossil cars.

You are right that to be part of the global warming solution, the electricity used by EVs needs to be carbon free - but actually to 'save the planet' ALL electricity generated has to be carbon free.

Stop using the carbon mix on the grid as a reason to bash EVs. Unless you want to bash every computer / phone / house / restaurant / office / water company / shopping centre / road signs / street lamps / council / etc / etc with the same stick.

The latest real life range figures on BEV ranges make bad reading, they seem to be getting 60% of range claimed by car makers - even the Jag i-Pace only getting 150 miles.
