+ An excerpt from :: SchNEWS :: DIY Guide - How to make Biodiesel. -something I will suggest to my older brother Craig, who is a skilled fabricator, among other mechanically-minded skills. He’s also just moved to a farm in the outback near Edmonton Alberta, so a big biodiesel barn must be available.

Biodiesel is biodegradable and non-toxic. 100% biodiesel is as biodegradable as sugar and less toxic than table salt. It biodegrades up-to four times faster than petroleum diesel fuel with up-to 98% biodegradation in three weeks. However, contrary to a popular misconception, it stores indefinitely in completely full, cool, dark containers. Compared to crappy fossil fuel diesel, biodiesel has the following emissions characteristics:

* 100% reduction of net carbon dioxide
* 100% reduction of sulphur dioxide
* 40-60% reduction of soot emissions
* 10-50% reduction of carbon monoxide
* a reduction of all polycyclic aromatic hydrocarbons (PAHs) and specifically the reduction of the following carcinogenic PAHs:
* phenanthren by 97%
* benxofloroanthen by 56%
* benz-a-pyrene by 71%
* aldehydes and aromatic compounds by 13%
* 5-10% reduction of nitrous oxide depending on age and tuning of vehicle.

For every one ton of fossil fuel burnt, 3 tons of CO2 is released into the atmosphere, biodiesel only releases the CO2 that it has taken in while the plants it is made from were growing, therefore there is no negative impact on the carbon cycle.

Equipment required

* 45 gallon drum.
* 1/2 or 3/4 Hp electric motor.
* Two pulleys which produce 250 rpm and a max of 750 rpm at mixer blade.
* A belt for the above.
* 12 inch rolled steel rod.
* Two steel shelf brackets (for the blade).
* 1 1/2 inch (38mm) brass ball valve.
* A hinge and a spring to act as a belt tensioned.
* 2000-watt electric water heater element.
* A water heater thermostat.
* 1 1/2 diameter piece of steel pipe * 3-5 inches long with male threads on one end.
* Assorted tat: angle iron, wood, screws etc.
