Waste Generation From Alternative Energy Sources

For many years we have been trying to get away from using fossil fuels and old inefficient electrical grinds. But, the move toward the widespread use of alternative energy sources has been a history of stop and goes attempts. Research and development of new technologies are needed for use to find cost-effective ways to harness this seemingly endless supply of clean, natural energy.

The most talked about form of alternative energy resources we can tap is wind power. The development and engineering of wind turbines continues to improve as the popularity, aka capital funding availability, spreads among the business community. In fact "wind farms" have begun to spring up across the world. The biggest issues with these wind farms are the noise vibration they emit and the danger to birds. No complete research has been completed to understand how the low ultrasonic vibrations may affect other wildlife; or humans.

Growing in popularity is solar energy. It is abundant and easy to capture for alternative energy use. The manufacturing of solar cells has rapidly developed with multiple uses adapted for small and even large scale applications. These solar cells gather the light energy given off by the sun which can be easily converted into electricity. It also is widely used to naturally generate hot water. Solar energy joins wind energy as alternative energy sources that create zero pollution. That is if you don't count sound or landscape alterations as pollution.

The largest and most abundant alternative energy source on earth is water. Governments and scientists backed by investors have been studying wave energy and the potential to tap it for clean energy. France has been operating a generator for a few years to study this potential and initial reports are promising.

The ocean is not the primary focus for water based alternative energy. Electricity has been generated from hydroelectric plants for almost a century. Places on earth that have a ready supply of adequate water sources such as rivers and lakes are in perfect position to generate clean energy. The issue becomes more complicated when a dam needs to be generated to create sufficient water flow to power the generators. Dams are not friendly to the wildlife and organisms in the area a dam may be built.

More recent technological advancements have opened the door to consider new alternative energy sources.

The first of these energy sources is energy we can create from the waste that people generate every day. Consider the number of landfills and expended oils. Methane gas can be captured and used to power generators. Not exactly "clean" gas but cleaner that coal and heavy oil. Waste oils from industrial and food consumption is likewise usually dumped. These waste oils can be used to power heaters and boilers to produce heat and steam as a power source.

Though the use of ethanol seems to have a very negative impact on the world's fuel supply it may prove beneficial in areas that can't efficiently tap into hydropower. We can't afford to use or food sources of wheat, sugarcane, grapes, strawberries and corn to provide us fuel when we need the nourishment for our personal source of energy. Likewise the consumption of soybean, rapeseed, and sunflower oils for bio diesel production is causing havoc on the world's food supply.

You can't discuss alternative energy without mentioning atomic energy from nuclear power plants. There is no alternative energy source that neither is as efficient nor can generate the enormous amount of clean pure energy than nuclear power. The waste product is the expended atomic energy that remains radioactive for hundreds of years. The amount of this waste product however, is minuscule relative to waste generated from other alternative energy sources.

You cannot create energy without some form of waste generation.

Waste

Daily generated an large amount of waste, considered how all material that is necessary to remove a home or a given environment, otherwise be could accumulate a large amount of micro-organisms harmful to health, or accumulate a huge dirt with similar consequences.

Naturally, to perform the task of rid of the garbage, it is necessary to have an appropriate container, to do so in an orderly manner, and going even further, the task of separating the garbage for subsequent recycling, which helps to later reuse what you have ruled out.

Basically we can classify the waste according to their composition chemistry, serving this often to find out how should be discarded, when doing so and its subsequent possibility of recovery through a process of recycling.

Organic waste: origin purely biological, which includes all those that comes from a living creature, ranging from food or the discarded during its development, until the remains of leaves and plants in general.Inorganic wastes: as opposed to the previous ones, it is industrial waste that have been manufactured by means of a non-natural process, being the best known derivatives of the plastic.Hazardous waste: the latter group seeks to differentiate from the other two, regardless of its origin (may be biological or not) you are looking for is to be treated in a differential way, being in this group those radioactive waste, waste with a high acid content, substances with a high corrosive power, and more often the medical material.

Other proposed classifications is in include Garbage technology as a group apart, either included among the Hazardous waste by having many of them with materials that can result in a subsequent soil contamination, that lately it is demanding that they can be made with recyclable materials.

On waste, there is a topic of debate for which never comes to a particular solution, which is the problem of the space where they are housed (or rather, from landfills) where many times destroyed large amounts of green space for the sake of obtaining a large garbage dump for a particular community.

The most widely accepted solution is separating the garbage for their subsequent task of recycling, but also requires an awareness that carried not to discard more than necessary, mainly emphasizing the reduction of pollution that would be achieved.

In no way must burn the waste in order to gain space, as contrary to search for a care of the environment environment, what is being done is to produce as much carbon dioxide, which as we have said many timesIt is harmful.

Converting Waste Heat to Electricity

With rapid industrialization, the world has seen the development of a number of items or units, which generate heat. Until now this heat has often been treated as a waste, making people wonder if this enormous heat being generated can be transformed into a source of electric power. Now, with the physicists at the University of Arizona finding new ways to harvest energy through heat, this dream is actually going to become a reality.

University of Arizona Research Team: The research team is headed by Charles Staffor. He is the associate professor of physics, and he along with his team worked on harvesting energy from waste. The team’s findings were published in the September 2010 issue of the scientific journal, ACS Nano.

Justin Bergfield who is an author and a doctoral candidate in the UA College of Optical Sciences shares his opinion, “Thermoelectricity can convert heat directly into electric energy in a device with no moving parts. Our colleagues in the field tell us that they are confident that the device we have designed on the computer can be built with the characteristics that we see in our simulations.”

Advantages: Elimination of Ozone Depleting materials: Using the waste heat as a form of electric power has multiple advantages. Whereas on one hand, using the theoretical model of molecular thermoelectric helps in increasing the efficiency of cars, power plants factories and solar panels, on the other hand efficient thermoelectric materials make ozone-depleting chlorofluorocarbons, or CFCs, outdated.

More Efficient Design: The head of the research team Charles Stafford is hopeful about positive results because he expects that the thermoelectric voltage using their design will be 100 times more than what others have achieved. If the design of the team, which they have made on a computer does work, it will be a dream come true for all those engineers, who wanted to catch and make use of energy lost through waste but do not have the required efficient and economical devices to do so.

No need for Mechanics: The heat-conversion device invented by Bergfield and Stafford do not require any kind of machines or ozone-depleting chemicals, as was the case with refrigerators and steam turbines, which were earlier used to convert waste into electric energy. Now, the same work is done by sandwiching a rubber-like polymer between two metals, which acts like an electrode. The thermoelectric devices are self-contained, need no moving parts and are easy to manufacture and maintain.

Utilization Of Waste Energy: Energy is harvested in many ways using the car and factory waste. Car and factory waste can be used for generating electricity by coating exhaust pipes with a thin material, which is a millionth time of an inch. Physicists also take advantage of the law of quantum physics, which though not used often enough, gives great results when it comes to generating power from the waste.

Advantage Over Solar Energy: Molecular thermoelectric devices may help in harvesting energy from the sun and reduce the dependence on photovoltic cells, whose efficiency in harvesting solar energy is going down.
How It Works

Though having worked on the molecule and thinking about using them for a thermoelectric device, Bergfield and Stafford had not found anything special till an undergraduate discovered that these molecules had special features. A large number of molecules were then sandwiched between electrodes and exposed to a stimulated heat source. The flow of electrons along the molecule was split in two once it encounters a benzene ring, with one flow of electrons following along each arm of the ring.

The benzene ring circuit was designed in such a way that the electron travels longer distance round the rings in one path, which causes the two electrons to be out of phase when they reach the other side of the benzene ring. The waves cancel out each-other on meeting. The interruption caused in the flow of electric charge due to varied temperature builds up voltage between electrodes.

The effects seen on molecules are not unique because any quantum scale device having cancellation of electric charge will show a similar effect if there is a temperature difference. With the increase in temperature difference, energy generated also increases.

Thermoelectric devices designed by Bergfield and Stafford can generate power that can lit a 100 Watt bulb or increase car’s efficiency by 25%.

Biomass Advantages - Put Your Waste Products in Your Gas Tank

Check out these biomass advantages.

1. Biomass energy resources is plentiful.Anything that will decompose and/or burn can be used as biomass energy. Therefore, biomass resources are very plentiful. Grass clippings, animal waste, corn stalks, acorns, tree limbs, meal scraps ...... can all be used for biomass energy.

2. It is easy to convert to fuel I used to drive by a landfill in Indiana every month. There used to be pipes coming out of the landfill with flames that never stopped. They were burning off methane gas from the buried waste. Alcohol has been around for thousands of years. In fact, automobiles and other machinery were running on ethanol almost 100 years ago. And guess what? Brazil, the fifth largest country in the world is independent of foreign oil. they run all their cars on Ethanol. So the technology is there.

3. The Technology is There. The technology is there to produce alcohol as a fuel or to make biodiesel fuel. Farmers were using it almost 100 years ago. Henry Ford was an advocate of alcohol fuel before the Prohibition. Brazil, the fifth largest country in the world, uses nothing but alcohol as it's choice of automotive fuel. Alcohol itself has been around for thousands of years. And anyone can get a permit to produce alcohol fuel from the government.

4. Helps to utilize idle farmland and deforested areas. There is still plenty of land out there that can be producing biomass. Using this idle land will produce biomass, create jobs and help us break away from foreign oil. A great plus for biomass advantages.

5. Biomass absorbs CO2 If it is produced on a renewable basis using biomass energy does not result in a net carbon dioxide increase as plants absorb it when they grow. Through the process of photosynthesis, carbon dioxide is absorbed into the plants. When burned, CO2 is emitted but at least it is balanced out. fossil fuels only add CO@ into the atmosphere.
