These attributes make it a good complement for lithium ion and it looks like CATL already has such a battery already to at least the prototype stage.
I suspect from now on companies with subsidiaries in Japan will be sure their top level meetings don't take place on Japanese soil.
The sleight of hand comes in where, in the beginning, the "holes" are atoms in the substrate that have lost an electron which, by the time the hall effect appears, those holes are now moving but in the beginning they were stationary.
In fact, in semiconductor physics as taught, both the 'electron' and 'hole' are in fact quasi-particles and only tenuously connected to the electron of the standard model.
As Musk pointed out some years ago, hydrogen is not so much a fuel as it is an energy storage medium. Right out of the gate creating the hydrogen reduces the system efficiency by about 50% because of the electricity required.
In essence then hydrogen fuel cells are just a less efficient form of electricity that require a complex and expensive mechanism to turn into motive force. Possibly useful for shipping or trains but not the way to bet for cars.
