Bulletin: Biodiesel

This is a draft document where I am storing my notes...

• Seems that water contamination is a big risk for any plan using waste cooking oil.
• Of all the how to guides I've found on the internet, this one has the best detail:  The Duda Diesel Guide on How to Make Biodiesel
• Potassium Hytdroxide or Sodium Hydroxide can be used
• Methanol is the preferred choice because it is cheaper due to taxes, but ethanol can be used.  The process is more difficult.  (how?)
