You are all thinking of mechanisms : What about the well known practice of using fresh and used veggie oil in IC engines ?
Filter to 5 microns and heat--to 70 / 80 deg centigrade at which point viscosity approaches that of diesel.. its pretty useable after that …
So, why not pre heat the oil?
Filtration is not a problem in stoves …
