Disclaimer. After nearly 40 years managing money for some of the largest life offices and investment managers in the world, I think I have something to offer. These days I'm retired, and I can't by law give you advice. While I do make mistakes, I try hard to do my analysis thoroughly, and to make sure my data are correct (old habits die hard!) Also, don't ask me why I called it "Volewica". It's too late, now.

BTW, clicking on most charts will produce the original-sized, i.e., bigger version.

More on the Vanderbilt super capacitor

I mentioned the supercapacitor, a new kind of electricity storage device, orders of magnitude faster to charge and orders of magnitude larger storage capacity than batteries in this post.   The team who discovered it has done more work on it.

Researchers at Vanderbilt University are developing a new generation of supercapacitors that can function even when they are subject to weight and vibration stress. Translation: the drywall of the future will store enough electrical energy to power your home electronics and appliances.

The new supercapacitor report from Vanderbilt was published in the journal Nano Letters on May 19. The team subjected its silicon supercapacitor to stress tests replicating vibrational accelerations of more than 80 g, which is more than you’d get if you were a turbine blade in a jet engine. They also went up to 44 psi for stress/pressure.
In both cases, the team found that the supercapacitor operated “flawlessly” in terms of charging and discharging, while maintaining its storage capacity.
