Time will tell if they ever are able to bring a product to market. Energy density comparable to lithium batteries is great for a capacitor but we really need something an order of magnitude greater. Lithium is no longer adequate for the new generations of electronic devices and has never been adequate for a car.

That's the great thing about markets:

a.) EEStor doesn't seem to be able to deliver. But over time someone will. Competition drives progress.

b.) Markets don't require one-to-one replacements. 200 miles of range and a recharge time of around a minute would be fine with maybe 80% of all drivers.. Not 100%, but enough to make such a product comercially viable (if the price is right).

“a.) EEStor doesn’t seem to be able to deliver. But over time someone will. Competition drives progress.”

Unless it is physically not possible as a number of super capacitor engineers have been saying.

“b.) Markets don’t require one-to-one replacements. 200 miles of range and a recharge time of around a minute would be fine with maybe 80% of all drivers.. Not 100%, but enough to make such a product comercially viable (if the price is right).”

Except nobody has a 200 mile battery range. They are talking 40 mile range for cars costing less than $50,000 and about a hundred miles for the $100,000 models.
