I thought that was weird. These days EVM makers are normally very concious about not exposing high voltages, unless its an EVM for actual high voltage devices. It really complicates approval and liability related issues, even though you may be supplying the EVM as a tool for competent engineers to work with.

I don't think they intend to do an official approval for this. They would make ~10 units, keep ~6 inside, and supply ~4 to friendly partners.

Holy crap that's hilarious. Thank you - I've updated my blog post to include this, and waybacked it too. No covering up this embarrassment.

I think those are custom uBeam transducers, a prestressed uni/bimorph or cantilever, basically a variation on the Murata, and certainly does not meet the specs announced in the Oct 17 pitch deck.

About 60, but doubt you can read much into it
