"If the layer thickness can be dropped to 1 um, then it works as 130nF 25V capacitor... and stacking 10000 of these would give 1000 uF 25V cap in 1 cm height..."

"So….after taking a long break from "The EEstory" - what does "Leakage current is better than tested commercially available Aluminium Electrolytic (AE) capacitors" mean?  Isn't this the ultimate…"

"anti - I did say when I first did it that I wanted it checking. I do these calcs quickly. Were it life and death I'd check myself 10X. And I'm sure pharmacists take care not to use mixed units - and probably use calculators too. LOL. "

"Simple calculations 100 X out by your own admission, thank God people don't make life and death decisions on your maths tom If a pharmacist was out by a factor of 100 the bodies would be stacking up quite quickly.   Do we believe your…"

"At this very low ED there is no reason for BT to saturate. From these figures we have 250V - 10u - 13nF 1500V - 35u - 3.6nF k is identical to within 5%. "

"For high voltage 250->1500, the layer thickness goes up 3X and capacitance goes down 3X. So it is the same k=28 material, only 3 layers in series."

"anti - don't embarrass yourself. Do the (simple) calcs for yourself, then go look up ED of electrolytics. In view of the fact that initially I has a X100 error that made my froth enthusiastic it is stupid to call me part of a "price…"

"Correct, the only way to do low voltage and retain energy density is go to really thin layers. Notice that when comparing the groups of samples (C1, C2, C3) nF and therefore k went down linearly as voltage went up (and worse), as you would…"

"electrolytics are 0.8J/cc or (good ones) 2J/cc. So that is 4X - 10X better than this - for the highest ED high volatge layers. It is rubbish. "

"http://www.daycounter.com/Calculators/Plate-Capacitor-Calculator.phtml I used that calculator for k. For example 506.7mm2, 0.010mm, k=28 gives C= 0.0126uF. "
