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.

San Francisco Premieres Solar Powered Wi-Fi Bus Stops

Filed Under (Solar Energy, Uncategorized, photovoltaic systems) by yoni on 19-06-2009

San Fransisco, California is making a splash in the civil planning industry. At the end of May, 2009, Mayor Gavin Newsom cut the ribbon on the first of many Solar Powered Wi-Fi bus stops that will be lining the streets of San Francisco in the coming 5 years. These sleek, curvaceous and modern bus terminals do it all. Their LED lights, intercom schedule system and even Wi-Fi routers are all powered by the stream-lined and efficient solar panel roofing. Talk about efficient! This bus stop in the Richmond district of sunny San Francisco, California is the first of about 1,100 solar powered, Wi-Fi bus stops the city plans to have in place by 2013.

Cleverly Designed With the Environment in Mind

The solar panels embedded within the poly-carbonate roof are said to harness enough energy to run all of the bus stops operations and even have some left over to return to the grid. This patented approach to solar panels was created by 3form Materials Solutions just for this project and the structure was designed by Olle Lundburg of Lundburg design. He says it was his first civic project. To add to the appeal of these innovations, they are produced 75% of recycled material. Certainly an eco-friendly production.

In addition to benefiting the frequent users of San Francisco’s public transportation, this project will also have one key benefit for the city: Free Wi-Fi, everywhere! I’m sure no one has any complaints about this. There will be enough of these Wi-Fi powerhouses to make the whole city a Wi-Fi zone. Upon cutting the ribbon Mayor Newson said, “Transit shelters that use photovoltaics, LEDS, and Wi-Fi are going to be standard in the future and I’m proud that San Francisco is once again acting like the pace car for other cities by trying and implementing these technologies.

Setting an Example: Will the Rest of the World Follow Suit?

So what’s the catch? Well, there isn’t really one. Although the MTA hiked fares by 50 cents, they claim it has nothing to do with the extreme expense of these bus stops ($25,000 to $30,000 each), but many people deny this. For now, no one is complaining. These bus stops satisfy everyone from the environmentalist tree hugger, to the internet-dependent business man, to the average Joe trying to get to work. San Francisco, California is setting a standard of excellence and forward momentum in the United States and hopefully other cities and states will follow suit very soon.

Alternative Fuels Are Found at Your Favorite Restaurant

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.

Conservation vs. Convenience: People are Creatures of Habit.

The luxuries and necessities that we have grown so accustomed to are the reason why the switch from oil to a renewable source of energy will not happen soon enough for us to shed our dependence on a finite resource. People talk and say that we need to cut back, we are destroying our world, but many are not doing anything about it.

It was trendy to boycott, to conserve, and to act when the gas prices shot so high. Talking about solar power, hydro electric power, global warming, and alternative fuels was the Hollywood thing to do. Now that the prices at the pump have fallen back to a reasonable rate, people have fallen back into their habits of traveling more, filling up the gas tank, turning the heat up just that little bit so they can be warm instead of just ‘not cold.’

A Way of Life Obtained through Progression Cannot Be Sustained Without Progression

These habits are not bad habits, but they are the actions that perpetuate the dependence on oil.

They are not wrong doings in and of themselves, but they are hurting the environment immensely.

It is not inherently evil, but it is destroying the world.

It is not intentional, but it is real and now, what other choices do we have?

It Needs to be Practical to Be Applicable

Convenience most likely will be the determining factor. Fuel Cell cars, poised to be the rescuer of the ozone and our wallets, cannot yet sustain a vehicle for more than 35 miles without a refill. Outside of California, filling up is out of the question because there are no refueling stations. The environment will benefit now if the changes are made, but people will not benefit, and that will hold people back. The Earth cannot be saved without sacrifice.

Home energy solutions are in the works but they are too distant, too impractical, too expensive. Things like hydro electric power and solar power feed off resources we already have, but to make them practical the technology would have to sustain a home with all of the necessities and most of the comforts and be affordable to the majority of Americans. While both alternative energy resources are on the way to doing this, neither is there yet.

Questions that Need to be Asked

What switch will we see when we have the ability to sustain our houses with alternative energy? Will houses throughout Arizona, Nevada, and California have large photovoltaic cells on their roofs? Will the coastal cities like New York, Boston, and Miami take in their energy from generators on the ocean floor? Will people be asked to spend their own money, or will the government offer incentives? Will that increase taxes? And for who? What will happen to those who don’t convert? What will be the socioeconomic impact be?

Long term, the effects will no doubt be positive, but it’s likely that in order to take that great leap forward we will have to take several steps back first. We must come to grips with the possibility that if we do not sacrifice a little now, we will have to sacrifice a lot more painfully later.

Wind Turbine Turmoil

With all of these possibilities for alternative fuel it’s no surprise that the most prevalent and practical is the one that doesn’t need to be manufactured, it comes to us like the breeze—Wind Power. Gigantic windmills pepper the hill lines of many states giving a safer, cleaner, and more economic power source.

With the exception of Don Quixote’s vicious and unprovoked attack of windmills, they are in general widely accepted as an efficient way to lower costs of electricity. Energy from windmills is significantly cheaper than the usual cost of electricity. Wind powered turbines yield three times as much energy for the cost as compared to gas turbines.

New York, Dedicated to Alternative Electric Power; New Yorkers, eh…not as much.

Big plans are in the works for New York City, who are so invested in the idea of a windmill it has been on their state crest for 400 years. It will take another 15 or so years to actually construct the windmills though. The windmills will be set up on bridges and buildings and could provide 10-20% of the city’s energy. So during the next city wide blackout in New York, a smooth 10-20% of the city won’t get looted.

The project is an ambitious one and, depending on the economy, it could be an unrealistic one. When approached with the possibility of windmills on his building, Donald Trump said he likes the idea of windmills in the city, but not necessarily on his building.

Why would he? It’s not like he has any trouble paying that extra 10-20% difference in his electricity bill.

Save the Birds Now, or Save Ourselves Later?

In Puerto Rico, windmills made some unlikely enemies: wildlife conservationists. Those who want to protect the environment by using a safe, clean, renewable form of electricity for humans were in direct confrontation with those who want to protect the innocent little Nightjar, a grey night bird who dwells in the forest that was the desired area to construct the windmills.

There were merciless battles of folk songs, free love, and picket signs. The battle field was riddled with burned out victims of protest, herbal tea, and Volkswagen vans. Needless to say, the need of the Nightjar beat out the need of the humans. Puerto Rico will not have the windmills that could sustain power for more than 20,000 families, but they do have Nightjars!

The rationale for U.S. Fish and Wildlife Service, the opposition to the humbled windmill, was that Puerto Rico is all set with its oil, which burns more than enough to provide electricity for the island. A tip of my hat goes to you, Puerto Rico, and boy am I glad to know there is somewhere in this crazy world where I can still hunt Nightjars!

Whether it is Don Quixote, Donald Trump, or those at U.S. Fish and Wildlife Service, they show what a truly self sacrificing bunch we humans can be, if not downright masochistic. Whether it’s a keeping your corner office view windmill-free or keeping an ugly grey bird fat and happy, don’t ask us to sacrifice what we want, we will only sacrifice what we need: a renewable energy source and our earth.
