Oh EEStor we still love you and your claims of orders-of-magnitude superiority over all others. Please deliver a product so we might drown your sales department in orders.

It is always a bad sign that press releases take precedence over the basic research and engineering. LOL

Why don't you? He is actually your President too, not just of those who voted for him.

Sadly this is becoming the norm.

You cannot really blame them, they have to get funding somehow but sometimes the claims are less based in practical reality and more based in theoretical results and expected advances in technology development.

A bit like the business development plan of the 'underpants gnomes' from the TV program 'South Park'. Obtain underpants ====> ? ====> PROFIT !!!!

Having underpants versus not having underpants is a strategic advantage.

You still have to put all that energy in the battery, somehow. Triple the range, triple the energy needed for a charge. Triple the cost and complexity of the infrastructure.

Exactly! Using the 'balloon' analogy: "...pumping more air into a balloon, the more likely it is to burst."

AT last, a guy that can break down the math on this. Excellent point!

So if I fill a balloon with methane, and fill an identical balloon with hydrogen-oxygen stoichiometric mixture, which one weighs less? How do you know they are inflated the same? Which one make the loudest bang (you know the answer to this, too easy).

Not necessarily. If range is tripled charging is at 1/3 the frequency (for given total electrical miles driven). So charging problems don't change. There's still the trade-off between higher charge current/shorter charge time, but that's another story.

It will be hard to match the energy transfer rate of a humble gas pump, which amounts to Megawatts.

So they are now using Li+ ion batteries to rig the roulette wheels? hmmm.....

The new thing is prevent dendritic lithium crystals from peeking out into the electrolyte and shorting out the cell. Good idea. Too bad I didn't think of it first.
