Bio-bug
o Processed sewage
o VW
o GENeco
Subsidiary of British sewage treatment
o Prototype
o Methane produced through dewage though anaerobic digestion by
bacteria
o Methane treated by biogras upgrading
CO2 being separated from the biogas
o Converted 2 liter 4 cylinder engine can reach speeds of 114
o Regular gas to start
o 70 households of human waste can power the car for a year
The Greasecar system is a two tank fuel system. The vehicles existing diesel
tank and filter will supply diesel fuel to the engine at start up and shut down. After
start up radiator fluid will transfer heat from the engine to the heat exchangers in
the Greasecar fuel system. These heat exchangers will heat the vegetable oil in
the fuel filter, lines and fuel tank. The heat will reduce the viscosity of vegetable
oil so that it is similar to diesel and can be injected into the engine properly.
When the vehicle is being shut down for a period long enough for the fuel to cool
the vegetable oil must be purged from the fuel system and replaced with diesel
for the next start up. Purging generally takes around 30 seconds and can be
done while driving with the push of the button on you Greasecar controls.
No sulfur content in veg oil
Veg oil plants absorb more co2 than what they release when burned,
carbon neutral
Cellulose – plant fiber
1.3 billion tons of potential fuel
Corn stalks, grass, trees
To convert to fuel, it must be broken down to sugar
o Conflicts with cellulose’s very nature
No commercial producers
Can be continuously grown and harvested
One of the cleanest burning materials
Technology isn’t fully there

Sugar Cane
Second to corn in useage
Helped some countries become energy independent
Not the easiest on a car’s engine
Uses more of the plant than corn, but not everything’
Downfall: can only be grown in warm places
Watermelon:
Watermelon juice has a high concentration of directly fermentable sugars
o Could be fermented into ethanol
Blemished/rotten watermelons could be reused as fuel or feed instead of
being put back in the ground
Contain high amounts or lycopene and l-citrulline
o Important nutrients for humans
