#1 Just when Com Ed is going to double our rates in Ill.

Oh well...

#2 Sceptical in details, hopeful in principle.

#3 Yep. Has a taste of cold fusion about it. Still, sometimes there really are game changers.

#4 COOL!!!!

Oh, I thought you said flux capacitor ...

#5 The problem with capacitors is that they want to discharge near instantly, if they"ve overcome this problem, then they"ve made a real life breakthrough.

#7 The Texas startup they're mentioning is EEStor, Inc. Here is a LINK to an article from late last year. If they can do what they claim, it might change the playing field a bit.

#8 Actually, you have to get to page 3 to get the caveats:
"Regarding concerns about temperature, leakage, and ceramic brittleness . . ."

The device doesn't work at temps less than -20C
(-8F). It also tends to crack under repeated jarring. The cracking might cause several thousand volts to discharge suddenly.

As they say in the article "What happens when a vehicle crashes and the device cracks?"

#9 old skool pitch..just a sample..

EEStor. "We're the first application, and that's thrilling for us. We took the initial risk because we believed in what they are doing. And energy storage is the game changer."

The key challenge, however, is to ensure that the barium-titanate powders can be made on a production line without compromising purity and stability. "Purification gives you better production stability, gives you better permittivity, and gives you the high voltages you're looking for," says Weir. "We've now got the chemicals certified and purified to the point we're looking for." (Better permittivity of the insulator improves the amount of charge that can be stored without letting the current leak across the two plates.)

Mines, Processes, and Snake oil the old Cons are Legends and True! Good Luck but don't invest just listen and enjoy a few.
