Yes I know that, otherwise I wouldn't have ventured an opinion. >wvo biodiesel is a great idea >in general, but a logistical nightmare for our circumstances: sourcing >+ transporting chemicals across international borders, How so?

Make it in advance in Helsinki and take it with you. I've done such things without any difficulty, so have many others. >if it is capable of generating electricity for live >sound gear without all the chemical inputs, Methanol and potassium hydroxide are extremely common chemicals, available everywhere, certainly in Helsinki. >glycerol byproduct + other >difficulties.

You're far from alone in that too. We have several times provided biodiesel to power the generators at big two-day summer music festivals here in Japan. No need for centrifuges. >keeping it as simple as practical! I disagree.

And biodiesel is much better fuel than WVO anyway. What sort of WVO kit are you planning to fit to your vehicles? (Yes, it needs a kit, not cheap - unless you're willing to put the fuel system at risk.) Are you aware that you'll have to make sure that the WVO you collect is suitable for use as SVO fuel? That means titrating it: Fuel quality http://journeytoforever.org/biodiesel_svo.html#gnl Titration for SVO http://journeytoforever.org/biodiesel_svo.html#titsvo Titration for SVO is the same process as for making biodiesel, but the purpose is different. With biodiesel, it simply tells you how much catalyst to use, then you go ahead and do it. With SVO, however, it tells you whether the fuel is usable or not, and if it's not you have to find a source of better-quality oil. It's not less trouble, it's more trouble. If you're hoping that a centrifuge can solve the oil quality problem, forget it - the high levels of acids in poor-quality oils cannot be removed by a centrifuge. The only way to do that is to use a chemical process called transesterification, which is how you make biodiesel.
