"It's a paradigm shift" - EEStor's Ultracapacitor

[TheOne]

ok thanks, I did not know that was big like that and quite massive height! 50kg

Remember when you place caps in series you must divide the capacitance by the number of caps you connect.
Eg. ten 2.5V 3000 F caps in series will give you 25V at 300 F.

31F @ 3500V  = 189MJ, not bad from 330Lb, much better than a hompolar generator or compulsator for energy density, I wonder what the ESL and ESR are?  If they are less than 1 milli ohm it could have military applications not that we need more weapons on this planet. If electric motors were good enough it would leave a top fuel dragster way behind on the 1/4 mile.

Until SiC semiconductors become mainstream the 3500V output is a problem, I could see super capacitors being very useful for a hybrid.

How many Farads do these supercaps have ?
What about shortcircuit them ?
Would it go boom like a bomb then ?
(in a car accident for example..?)

The metals have resistance which under short circuit conditions would have to absorb the discharge. They would vaporize and it would be energetic.
Also if the impedance were low enough the short circuit current would cause a magnetic pulse inducing a current in surrounding conductors. Even blood is a conductor, not a good one, but Bob Beck used the discharge from a camera strobe capacitor to induce enough current in lymph nodes to zap HIV. This pulse would be MUCH larger.
An interesting thought is would it kill car computers for a distance around the collision.

Anyone hear any news of EEstor's battery lately seems they have been as quiet as steorn...
