biodiesel?

the price of fuel is going up. a new thought: we might think about running our generator on bio-diesel or even waste veggie oil rather than propane, as we had previously thought we would. a propane generator will make our fuel supply simpler, but propane is not renewable. veggie oil is. at this point, veggie oil can be had for free from restaurants. in the future, if using it catches on, that may not be the case, but there is a lot of waste veggie oil out there. i've found a web site that details how to take a used diesel engine of lawnmower size (6-10 horsepower, $150-$200 and attach a DC alternator ($165) to that for operating pumps, charging batteries and inversion for operating 120v devices. this might be a great way for destiny to lower operating costs and be a bit greener.
