End of the year celebration

We showed off our Fat to Fuel car at the NGHS end of the year celebration. It was great to share our project with so many other students, faculty and other members of the community. We demonstrated the car and when we switched it from diesel to WVO there was a clear consensus that the exhaust smelled a bit like a Chinese restaurant. In our experience the oil from Chinese restaurants has been the cleanest and least contaminated by animal fats and other impurities. You can see the brochure holder attached to the side of the car. We gave away almost all of them to interested visitors.

Here are some of the most common questions we received:

Q: How can I do this to my car so it can run on waste veggie oil?
A: You can only do this type of conversion on a diesel vehicle, so unless you have a diesel you'd need a different car.

Q: Did you guys really do the conversion? Does it work?
A: Of course we did, and of course it does! Can't you smell the egg rolls?

Q: How is this better for the environment?
A: Using WVO in a vehicle is basically a form of recycling. One advantage is that the waste veggie oil (WVO) produces less overall pollution than petroleum based diesel fuel. The other major advantage is that WVO is practically carbon neutral. Since the plants it comes from have absorbed carbon from the air as they grew, burning the WVO just cycles the carbon back into the atmosphere to be absorbed by more plants. Burning petroleum based diesel burns carbon which has been safely stored under ground for millions of years, adding to the overall amount of carbon in the atmosphere.

Q: What kind of mileage do you get?
A: We haven't run the car enough to calculate it, but other people who have installed similar WVO systems have calculated that they drive about 100 miles on each gallon of diesel fuel. You only need to run the car on diesel until the engine and WVO tank heat up, and then you can switch to pure WVO.

Q: Why don't all cars run on this?
A: The problem is that there really isn't enough waste vegetable oil around to feed our voracious appetite for oil to run our cars. This type of waste veggie oil (WVO) system could be used in many vehicles though. For example, a company which owns lots of restaurants or food processing factories might be able to use oil from their own fryers to power their fleet of trucks.

Mr. Jose DeLaGarza, one of our building engineers, was instrumental in making this project happen smoothly. Thank you Mr. DeLaGarza!

Finished Mural

Our mural shows how we recycle used vegetable oil to run our car.

If you look at the hood, you can see what is under the hood, allowing the car to run on WVO.

First, energy from the sun is converted to chemical energy by photosynthesis. Crops like corn and soy use photosynthesis to absorb carbon dioxide from the air as they grow.

The corn and soy are pressed into oil and used in local restaurants.

We collect the oil and filter all the crumbs and impurities out so they don't clog the diesel engine. The oil is filtered 4 times through 400 micron, 100 micron, 30 micron, and 15 micron filters.

And that clean oil is what goes into the 15 gal. WVO tank that is mounted in the back of our Benz.

The mural

We are painting the car to show people how it works. One side is full of flowers to illustrate that the Veggie Oil Car is better for the environment than regular cars. The other side of the car shows the energy flow from corn to fryer oil to filtered oil to the WVO tank of our vehicle. The mural on the hood shows the engine modifications we made to convert the car to run on WVO (waste vegetable oil.)


We got to show off the car to an auditorium full of students and instructors from After School Matters. We did a presentation about how the filtration unit works and how energy flows from the sun to plants which are converted to oil and then filtered to run our WVO vehicle.

Happy Earth Day!!

We are celebrating Earth Day 2008 by painting the mural on our Veggie Oil Vehicle.

We finished the conversion last week and tested it out. Everything ran great. We still need to install a temperature sensor (a digital oven thermometer we bought at Target) and do a bit more testing of the car to make sure all systems work at full heat.

Earth Day is coming up on April 22nd.

What are you doing for Earth Day?
