With the dwindling supply of fossil fuels and a rapidly disappearing ozone layer, the search for new energy sources is getting kicked into high gear. And while the advent of renewable energy has sparked discoveries in electric, wind, and solar power, more and more researchers are turning to biofuels as the answer to the world’s energy crisis. Interestingly, recent research has shown that the watermelon is a valuable source of this much sought-after biofuel.

What is biofuel?

Biofuel is a type of fuel derived from renewable biological resources (ranging from a banana peel to grass clippings), or biomass. Biomass is generated by living organisms or metabolic by-products and is most commonly produced by plants and animals.

Why the watermelon?

According to Wayne Fish at the U.S. Department of Agriculture, “About 20% of each annual watermelon crop is left in the field because of surface blemishes or because they are misshapen. We’ve shown that the juice of these melons is a source of readily fermentable sugars, representing a heretofore untapped feedstock for ethanol biofuel production.”

Watermelons grown for renewable energy?

Although it is easy to believe that this delicious summertime-favorite fruit was put onto Earth merely for our enjoyment, it is hard to ignore its eco-friendly benefits.

The juice from one watermelon can be used to produce the following high-demand fuel sources:

-       Ethanol

-       Lycopene

-       L-citrulline

How does biofuel conversion work?

The secret exists in the watermelon’s sugar. The sugar is distilled into alcohol, which then becomes the much-needed energy source. Once the juice is converted into energy, it can be used for alternative vehicle power.

Could one fruit make a big enough difference in renewable energy?

Yes! It is estimated that about 50 percent of each watermelon could be used for renewable energy. In fact, every acre of “dud” watermelons (that would otherwise be going to waste) would supply up to 20 gallons of fuel. Even more beneficial, watermelons provide a clean source of energy that differs greatly from the pollutants found in fossil fuels.

Early Experimentation with Alternative Fuels

The first known use of vegetable oil as fuel was a demonstration of a diesel engine built by the Otto Company and designed to burn mineral oil. They tested it to run on pure peanut oil at the 1900 World’s Fair and it worked.

Another example of vegetable oil being used as fuel was investigated by Rudolf Diesel, the inventor of the diesel engine. Using vegetable oil to fuel engines of his design, in a 1912 presentation to the British Institute of Mechanical Engineers, he cited a number of efforts in this area and remarked, “The fact that fat oils from vegetable sources can be used may seem insignificant today, but such oils may perhaps become in course of time of the same importance as some natural mineral oils and the tar products are now.” What an uncannily accurate predication from almost 100 years ago.

Today, many people are experimenting and turning over to alternative fuels. With gas and diesel prices always on the rise and the more apparent environmental risk from using fossil fuels, consumers are looking for alternatives that can help power their engines.

Fast Food Fuel

Companies like GreaseCar knows exactly how consumers feel. They sell deluxe kits to convert your car into a bio-fuel car that uses used vegetable oil from restaurants. Most of these alternative fuel users utilize filtered frying oil that is collected from local restaurants. Most restaurants are happy to give their oil away as they generally have to pay a fee for proper disposal.

Going Green Means Big Savings for an Alabama School System

Recently in the news, agriculture officials and the Montgomery Public School system in Alabama are exploring the possibility of using cooking oil from the school’s cafeteria to fuel their fleet of school buses. Starting this fall, Alabama State students will collect cooking oil from the cafeterias, turn it into biofuel and use it to run buses in a pilot program. Students at the schools will also be encouraged to bring used oil from their homes.

“When we’re able to collect this grease and fuel for 72 cents a gallon, hopefully we’ll be able to do two things – we’re going to lower the fuel cost for the school systems and we’re going to be environmentally friendly,” state agriculture commissioner Ron Sparks said Wednesday. 

Having a steady and reliable supply of fuel that is less than a dollar a gallon and safe for the environment sounds like a win-win idea to a lot of folks.

Farmers Turn to Biofuel Cash Crops

Across the nation, farmers are growing cash crops canola and other vegetables in hopes of selling them for alternative biofuels. Some Pacific island nations are already using coconut oil as fuel to reduce their expenses and their dependence on imported fuels, while helping stabilize the coconut oil market. Coconut oil is only usable where temperatures do not drop below 62 degrees Fahrenheit, which makes it perfect for use in the South Pacific region.

Engineers as well as people looking for alternative fuel options have been experimenting with the use of vegetable oil as a fuel for over a hundred years. The petroleum shortages in the 30’s and 40’s catalyzed the research of vegetable oil as fuel and again in the 70’s and 80’s. This research shortly ended when gas prices fell and there was a greater interest in using biodiesel as an alternative fuel where extensive vehicle changes were not necessary.

According to Eco News a new biofuel candidate could end the debate about food crops being used as machine fuel. Camelina Sativa is a hearty grain that requires very little rainfall to thrive, producing double the harvest per acre of soybeans and an oil that functions well in colder climates.
