Obviously 48VDC has been around and internally they will probably still step down to 48V. But these 48V islands are nowadays inter connected by regular AC grid. They want to replace that interconnection with a 800VDc bus. I kind of assume they chose 800vdc because there are already bunch of stuff available from EVs which also have 800vdc battery packs now.
Much of the world's mains-voltage electronics run at 240V (historical) and have PFC circuits (which are essentially just boost converters) that run at ~400V DC link voltages. 650V gives you enough headroom to tolerate overshoots and still have an 80% safety margin with a single level topology.
This voltage also coincidentally is a convenient crossover point where silicon MOSFETs start to become inefficient and GaN FETs have recently become feasible and mass-produced.
there needs to be battery chemistry improvements. Otherwise, with existing batteries, charging at these speeds will cause too much heat and shorten battery life span. BYD is offering 1.5MW charging with increased battery lifespan and without increasing the heat dissipation requirements. Another improvement compared to current crop of batteries is charge curve. Charging from 80 to 95%, BYD batteries can handle higher power than current batteries at MAX
Shouldn’t it be possible for AI to filter out that a request is made to portray a real person? That seems almost like a trivial task for a good model. I am sure every now and then something will slip through, but I bet one could make it very close to 100% effective.
Consider the difference between "Generate an image of Emma Watson", "Generate an image of Hermione", and "Generate an image of a female hogwarts witch and student". We're getting less and less specific, but those are all likely to get you an image of Emma Watson.
Your filter has to pick out that, while they did not ask for a specific person, the practical result is likely to be the same. That's going to be tough to get near perfect.
AI development has become an excuse for ignoring consent. Of course it's possible to filter out requests. But culturally with X, it's not remotely likely, unless compelled by regulation with teeth.
