Hi Jull
Now do the same math with home produced bio-diesel.
The time taken to produce 200 litre is around 15 minutes, that is the time taken to pour the 5 off 20 litre drums into the receiving tank (it has a full width fine mesh strainer to remove the food scraps in the oil so I need to pour slowly). From then on the refining/filtering is fully automatic, the only and final input from me is to measure the cetane reading of the base refined oil and add the required amount of ethanol.
As I said before the base oil costs me nothing, the fast food shop is happy to give it to me and will give me more than I can use, the ethanol costs $185.00 including GST tax for 25 litres and I've never had to add more than 5 litres to 200 litres of refined vegetable oil to raise the cetane rating to 85/90.
That equates to $37.00 of ethanol per 200 litres of fuel, allow for the household electrical cost to refine the oil at say $5.00 and thats a total production cost of $42.00 for 200 litres, add to that the amortised cost of the plant (drums, pumps filters and filter core replacement every 1000 litres) at say an additional $10.00 and thats a total cost of $52.00 for 200 litres or $0.26 per litre.
My camping trailer carries 4 off 20 litre gerry cans and my Disco has the uprated 145 litre tank that gives me a total fuel capacity of 225 litres and at 10 litres per 100 kilometers thats a safe 2150 kilometers without having to buy any bowser fuel it I'm going away for the weekend or 1350 kilometers just on the tank.

And yes you need to jump to roaming section and show us your rigs and post pictures of your trips
