I had seen a video with a british man hitting his waste veggie oil with over 1000VAC at a very low current 10 microamps. The glycerin in the grease immediately fell to the bottom of the jar. Thus removing the need for significant amounts of methanol normally used in a transesterification process. I tried to copy this concept by using EL Wire inverts and electrocuting my unfiltered veggie oil. Sadly I did not get the same effect. I believe the standard EL Wire inverter is too low in voltage at only about 600VAC and rather high in current at about 20mA.
