here's all the energy-density related talk [with my comments]:

And the reason we coated the powders, to just back up a little bit, was aluminum oxide which is the highest resistivity material in the world, and the best sealant in the world, because when you add voltage to these materials you lose oxygen. If you coat the particle and it says so in our patent so this is all public information. You kill the loss of oxygen which totally shuts down the problem of putting voltage onto these products and losing permittivity {over time / aging}. [interesting idea that oxygen loss is the only source of permittivity loss ... maybe true for imperfect powders ]

The voltage breakdown on the aluminum oxide, certified mind you, in our news release, is 1100 Volts per micron. Now we're at 350 Volts per micron on our working Voltage. And you see we're more than 3 times away from our working voltage. Which is more than enough for safety of that type of activity, for voltage breakdown versus the working voltage. Usually 1.5 is more than enough. Were we see we're actually a little better than 3. [this was his most glaring scientific error ... lower permittivity in Al2O3 means very high concentration of voltage as shown in J.Y. Li 2007 paper so thhat he'll get breakdown at roughly 10 M/um instead of 350 V/um]

So, no real heartburn there of getting our voltage. Now another thing on voltage and I did put that in another news release is that we work deep into the paraelectric phase. In the paraelectric phase we have very sophisticated test data certifying that in the paraelectric phase there are no domains. And this is where the people out there ... the bloggers out there ... well, my God, you know, you're going lose your permittivity. Well you would if we were in the paraelectric phase.

I'm sorry. In the ferroelectric phase. Barium Titanate, Composition Barium Titanate is a 2 phase material ... is Barium ... it has a paraelectric phase and a ferroelectric phase. Now, all the colleges and universities and all those PhD guys out there are very familiar with the ferroelectric phase. If you apply a voltage to it you get to the voltage and have the main wall slippage and you lose your permittivity. It's not true if you're in the paraelectric phase and I pointed it out very clearly in one of our news releases. If you're in the paraelectric phase, it is very difficult to get polarization saturation cause your dipoles shift ... they are now electron clouds and you can expand them. [ does not overcome the fact that he would need to strip all his electron clouds away from his nuclei to get the needed polarization ]

7:03

And on top of not only that, we have a patent process, a patent pending process, where we can polarize our dipoles so the *all* shift through 45°. That means our polarization saturation has been improved by at least a factor of 4. [he needs a factor of 200 increase] Well, you see, that's not taken out ... a non-problem, now. So not only got the voltage breakdown under control, I got polarization under control, we've got the purification behind us, the chemical saturation
