I can never get the uspto drawings. It always says the quicktime plugin is out of date even after I have upgraded my quicktime to the most recent version.

Does it mean that what uspto is using is very old or what?

If the heater breaks when it's fully charged, you got trouble.

So when they mention in their patent how the eestor ultracapacitor works and how they are different and better.........how do THEY KNOW if no one else does.

Is any anyone else smelling TULIP(s)

As the device is charged, the operating temp decreases. As it is discharged, the temp increases. Voltage remains constant across the charge state. This and giant storage capacity are the main advantageous of this device type. The drawback for electric vehicles is the continuous draw required to maintain the operating temp. So perfect for grid storage, not so perfect for ev's.

same problem. Decreasing permittivity for a given charge state gives a rising plate potential. If you decrease temp while charging this device, the dielectric constant drops and bam, you're charged to max potential. You didn't store very much. For a given amount of energy stored, reducing K increases V. Heater breaks, K drops, voltage rises, battery breaks down. do I have this right?
