I have a 4x4 diesel truck that is my primary vehicle. I also have a 35kw gen that is powered by a Volkswagen turbo diesel engine. I only have one 500 gallon storage tank at the domicile and not much disposable income to put more stored fuel in. I was looking into bio-diesel production and can probably supplement with some cooking oils but was wondering at the viability of extracting fuel from algae or other sources? We have a possibility of taking over a facility here that recovers and disposes of petroleum wastes from the oil patch; can this be a viable source of fuel production? Ideas lend themselves well to development, so thanks in advance.
