Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

(link) where I posted this as the first comment:

The above is obviously not offshore, but it's the first turbine of Siemens's new direct drive turbines (in this case, a 3MW machine; they are also working on a 6MW one) which will also be produced for offshore use.

I wanted to show it because there have been a lot of scare stories about rare earth metals and the grip China has on these; direct drive turbines are one of the industrial products which could need such metals in its generator, but it needs to be said that such metals are in no way indispensable - other metals can do the job as well - you may lose a tiny bit of performance, but nothing that really changes the economics of the equipment, so the manufacturers are reasonably relaxed about it.

great Jerome, sei un grande!

excellent news about the rare earths too, i guess this was part of the 'china is b-a-d & s-c-a-r-y' narrative.
