Introduction to producing wind energy
Wind is a source of energy that has been harnessed for different applications since a long time.
The Chinese and the Babylonians have been famous for using wind power for the pumping of water for irrigation of crops some 4,000 years back.
And in addition to this, sailing boats were harnessing wind power long before that.
It has been recorded that wind power was used in Europe in the Middle Ages for other activities like grinding of corn.
In fact, this is what has been attributed to the start of the term windmill. To understand the concept of wind power, it is better to first understand the science behind wind formation.
With the sun heating the atmosphere unevenly, some patches of land become warmer than others; and this is where warm patches of air rise. With this, other air starts blowing to replace them and start a wind blowing. The energy produced from the wind is used by building a tall tower which has a large propeller on its top.
Garbage can now help in producing hydrogen
There is never an abundance of fuel as need for fuel is increasing day by day, while all the present resources of fuel are running dry across the world.
With the daily consumption of fuel increasing everyday, researchers have to find out new and efficient forms of energy. And this is when and how researchers have found out that is it possible to use the garbage that is thrown out, for producing hydrogen.
According to these researchers, all types of biodegradable garbage that ranges from sewage to left over food are all sources of valuable hydrogen fuel.
This is because it is possible to use this garbage to produce the alternative to fossil fuels, hydrogen fuels using the help of microbes that have been cultivated in special reactors.
It is because of the fact that researchers know that the burning of hydrogen only produces energy and water that they had started looking for ways for generating hydrogen en masse.
With this, the researchers hope to stop, and replace use of fossil fuels, which its burning only leads to the release of the global warming gas, carbon dioxide.
The Parabolic Solar Oven
The rising costs of non-renewable sources of energy because of its dwindling stocks has led to people looking for alternative forms of energy for their electricity, fueling and cooking needs.
One of the most preferred and convenient forms of alternative energy is solar energy, which is harnessed in many consumer products and both in homes and commercial establishments.
When you think of solar power in your equipment, the first thing that comes to mind is solar panels. However there are some products that have a more practical use when using solar energy like the parabolic solar oven.
Solar energy is one of the best ways of reducing the use of nonrenewable resources.
With solar energy, the sun’s rays are used to create electricity, heat water or other fluids, charge a battery, heat homes through glass windows and cook food.
Usually a solar oven is used for cooking food which is used instead of firewood and other fuels to cook meals. One of the more famous solar ovens is the parabolic solar oven.
Converting organic matter to hydrogen fuel with microbial electrolysis cell
With energy sources depleting by the second, researchers are always on the lookout for new and renewable sources of energy to meet the energy needs of the future.
One of the types of energy that is currently in demand is using ethanol as a fuel. However this is not that feasible as a renewable source of energy as producing economical ethanol from cellulose is expected to take a minimum of 10 more years.
This is because according to environmental engineering researchers, first cellulose has to be broken into sugars so that it is possible for bacteria to converts them into ethanol.
This is why an alternative method has been suggested where microbial fuel cells are converted into cellulose while other biodegradable organic materials are then released into hydrogen.
Deep drilling. A form of renewable geothermal energy
Petroleum, coal, oil and charcoal are all sources of energy which will deplete one day or the other in the future. This is the reason there is a continuous and constant search for new and different forms of renewable energy. And in connection with this, researchers from UC Davis, Stanford University, UC Riverside and the University of Oregan have found a renewable energy in deep drilling.
With the Iceland Deep Drilling Project, these researchers intend to sink a deep borehole in places where deep and hot rock is circulated by seawater. The reason they intend to do this is that these sites on land, usually have fresh water circulating them with different chemistry.
In other words, it can be said that this is a dry land version of a deep sea hydrothermal vent which provides researchers with an opportunity at looking at rocks and fluid together in situ. The specialty of the deep ocean hydrothermal vents is that they all support unique communities of living beings.
