Today EcoGeek put on a pair of pants that no longer fits. We're realizing that the days of metabolic bliss when we could run on greasy foods alone may have come and gone. This is why we were quite excited to read about Frybrid, a Seattle-based company that's converting diesel vehicles to run partially on waste vegetable oil. Dee-lish.
We ecogeeks have all heard about such things, but what's cool about Frybrid is that they sell kits to convert your own diesel vehicle to run on french fry remains. French fry droppings. Whatever.
The FAQ is surprisingly straight and informative, with nuggets (mm, nuggets) like this one:
How do emissions compare? This is a surprisingly difficult question to answer. What is clear is that Sulfur Oxides are reduced 100% and that burning SVO only releases the amount of Carbon that is absorbed from the atmosphere by the crop that produced the oil, in other words SVO is Carbon neutral. As far as other emissions, there simply has not been definitive research yet. In applicable studies, some show CO, CO2, NOx, and HC are higher, some show lower, some a mixture. It is my hypothesis that in a properly designed system, CO and CO2 should be about the same as petrodiesel, HC should be a bit less, and NOx a bit higher.
And Just to decrypt all that:
SVO= Straight Vegetable Oil (the stuff being burnt).
HC = Hydrocarbons (unburnt fuel which break down into nasy stuff).
NOx = Nitric Oxides (causes smog and lung problems).
CO = Carbon monoxide (causes long-term lung problems and short-term painless death).
And I'm assuming we all know what CO2 is.
