The Wind Energy Industry is Nothing New

Though our scientists may claim that they are inventing something new by using wind as a source of generating energy, the truth is that wind is being used for centuries for this purpose. An example of this is an article published in 1838, which clearly shows that even in those times, wind was considered an important source of energy.

Here are a few quotes that were recorded in the past, which prove that wind was always important in generating energy.

John Houghton from Cambridge said in his paper Global Warming: The complete Briefing, ‘Given that it has been used as a form of energy for a couple of centuries, wind is a very common source of energy. The fact that there were about 10,000 windmills to tap wind energy in the Year 1800 itself, goes to show that wind was an important source of energy in parts of Europe like Britain. Therefore it is not surprising that parts of the world like some countries from Western Europe such as Great Britain and Denmark and some countries in western North America are trying to revive ways of tapping energy from wind. Slim, tall and more efficient objects have replaced windmills to tap wind energy.’

Even other researchers from Cambridge have worked on this subject. Vaclav Smil in his paper Energies wrote, ‘The windmills in 19th century, which were at par with watermills of that period with regard to generating power, were of a different design. They were used in farms and on Railway stations. Before that, post mills of 1.5 and 6 Kilowatt and tower mills of 5 to 10 kilowatts were used in Europe for this purpose.’

Studies tend to indicate that though the use of windmill to generate energy started in China, it soon spread to parts of Europe like England in the 12th century and by the end of the century there were 12000 mills in the region that needed little water to produce electricity to meet huge industrial demands.

Other researcher and historians like Cynthia Shea in her paper Renewable Energy: Today’s Contribution Tomorrow’s Promise points out that other European economies like the Danish industry at a particular time used wind-power to satisfy 1/4th of their power needs.

In United States of America, policy makers while stating it to former President George W Bush said, ‘Since around the year 1900, windmills were used to pump water in farms and ranches in the country. They even led to the production of electricity and turbines. Before that grain was ground and water was pumped with the help of wind mills as early as year 200 B C.’

Dennis Hayes in his paper The Official Earth Day Guide to Planet Repair also verifies the same as he says, ‘Before Carbon-fired power plants, 8 million Midwestern windmills made electricity by driving water and crushed grains. There was no other way to do so before villages got electricity in 1920s and 1930s.’

Christopher Flavin in his worldwide paper Electricity for a Developing World: New Directions has also urged the underdeveloped countries to follow American example of how they used Midwestern windmills to generate electricity for their rural sector.

Windmills have been used for centuries for pumping water in rural areas. They also grind grains and do other small tasks. Though traditional windmills can also generate power, latest technology and wind power together can be the foundation of mechanical power and can generate electricity in underdeveloped countries

The history of windmills has been penned down extensively by Wilson Clark in his work Energy For Survival: The Alternative to Extinction. With regard to Europe, he says, ‘Developed in Seventh century in Persia, windmill reached Europe through Dutch and England in thirteenth century enabling them to generate 1 billion kilowatt- hour of electricity. The wind energy produced by windmills was used as a source of power to the sailing ships. The Persians again became the first to use wind to develop mechanical power and used windmills to put out water for irrigation. Whereas windmills were used in Persia in seventh century, it reached France in 12th and Denmark, Germany and the Netherland in early 13th century.’

Wilson further talks of America. He says, ‘Industrial growth in Midwestern United States led to a situation where windmill industry had capital investment of $ 4.3 million by the year 1900 with homesteaders and ranchers having their own windmills. Efficient and long-lasting windmills were also developed due to stiff competition. The windmill industry in United States continued to grow with various windmills being tried out for the best possible option. Whereas some windmills developed in 18th century needed fewer sails, those made in 20th century could run electric generators, pump water and generate electricity for American farmers.’

Wilson also explains how 1250 kilowatt wind electric station generated that much power in the hills of Vermont during the days of Second World War. This was the hard work of a man known as Palmar C Putnam, who was finding it difficult to pay for high electricity rates in the region.

Many new ways have been developed to generate energy in the last two centuries, the world is again returning to the old ways of generating power because of scarcity of oil, gas and coal. This is because they know that energy created with the help of sun, water and wind will never get scarce or exhausted.

Solar Wind Power: Generating Power In The Future

As the world discovers new ways to meet its growing energy needs, energy generated from Sun, which is better known as solar power and energy generated from wind called the wind power are being considered as a means of generating power. Though these two sources of energy have attracted the scientists for a very long time, they are not able to decide, which of the two is a better source to generate power. Now scientists are looking at a third option as well. Scientists at Washington State University have now combined solar power and wind power to produce enormous energy called the solar wind power, which will satisfy all energy requirements of human kind.

Advantages of Solar wind power.

The scientists say that whereas the entire energy generated from solar wind will not be able to reach the planet for consumption as a lot of energy generated by the satellite has to be pumped back to copper wire to create the electron-harvesting magnetic field, yet the amount that reaches earth is more than sufficient to fulfill the needs of entire human, irrespective of the environment condition.Moreover, the team of scientists at Washington State University hopes that it can generate 1 billion billion gigawatts of power by using a massive 8,400-kilometer-wide solar sail to harvest the power in solar wind.According to the team at Washington State University, 1000 homes can be lit by generating enough power for them with the help of 300 meters (984 feet) of copper wire, which is attached to a two-meter-wide (6.6-foot-wide) receiver and a 10-meter (32.8-foot) sail.One billion gigawatts of power could also be generated by a satellite having 1,000-meter (3,280-foot) cable with a sail 8,400 kilometers (5,220 miles) across, which are placed at roughly the same orbit.The scientists feel that if some of the practical issued are solved, Solar wind power will generate the amount of power that no one including the scientists working to find new means of generating power ever expected.

How does the Solar wind power technology work?
The satellite launched to tap solar wind power, instead of working like a wind mill, where a blade attached to the turbine is physically rotated to generate electricity, would use charged copper wire for capturing electrons zooming away from the sun at several hundred kilometers per second.

Disadvantages of Solar wind power
But despite the fact that Solar wind power will solve almost all the problems that we were to face in future due to power generating resources getting exhausted, it has some disadvantages as well. These may include:

Brooks Harrop, the co-author of the journal paper says that while scientists are keen to tap solar wind to generate power, they also need to keep provisions for engineering difficulties and these engineering difficulties will have to be solved before satellites to tap solar wind power are deployed.The distance between the satellite and earth will be so huge that as the laser beam travels millions of miles, it makes even the tightest laser beam spread out and lose most of the energy. To solve this problem, a more focused laser is needed.But even if these laser beams reach our satellites, it is very doubtful that our satellites in their present form will be able to tap them. As Greg Howes, a scientist at the University of Iowa puts it, “The energy is there but to tap that energy from solar wind, we require big satellites. There may be practical constraints in this.”

What is Free Energy?

Typically, one sort of energy, known as “free of cost energy” is a widely discussed issue now a days. With the advent of appropriate scientific developments we can extract the energy directly from the atmosphere, and which is unlimited in supply. The discussions are mainly about its availability or non-availability, and if available the supply is unlimited or not, and if it is available the costs involved in making it available.

The discussions also involve the verification of the claims of its supporters that it would be efficient to consume resources to investigate and cultivate it, as a probable alternative energy source.

The term “free energy gadget” has multiple notations when we talk about it. One of the possible outcomes of such a gadget is that it accumulates energy from a source which is not scientifically proven, and transfers it to the other source. And off course, it is free of cost too. It may also be some sort of a machine which accumulates cost free energy or a famous uninterrupted motion vehicle.

Such an uninterrupted motion vehicle as its name suggests, it will move everlastingly and will never need to be refueled. It looks beyond the reality now. But it is not beyond the reality to develop such scientific techniques which may convert energy hovering in the environment.

Reaping the benefits of nuclear power was beyond the reality till 1940 but we are now enjoying the benefits. Floating in the air like birds was a dream of humanity till the flying machines were invented by Wright Brothers.

The supporters of free energy maintain that we can extract huge quantity of energy from the Zero Point Field (ZPF). It can be termed as quantum mechanical condition of matter for an isolated system which is achieved by the system when it is in minimum possible energy state. This is known as “ground state” of the system. Almost a century back from now in 1913, the ZPE was suggested by Albert Einstein and Otto Stern to be a possible source of alternative energy. In quantum mechanics this can also be referred as “vacuum energy” and it is thought to reflect the energy of empty space.

One of the supporters of free energy, Hal Puthof, has equated the energy field within the vacuum with the bubble at the bottom of a waterfall. He describes the phrase ‘zero point’ as, for an instance, if the universe be frozen down to absolute zero where all thermal disturbance outcomes be cooled out, this energy remains intact. The consequences that originate from this well known phenomenon of quantum physics are not common even in active physicists.

However there is a class of physicists conducting research who are trying to investigate that it may be possible to access to energy deposits to be used as alternative energy resource or this energy field may be result of activation of inertia and gravity. It is very essential to find the reasons to believe the above two repercussions. Because this energy can be controlled and may be inertia and gravity bring some engineering solution. There has been a development in sub field of the area (cavity quantum electrodynamics) in managing the release rate of energized atoms and molecules activity in laser research.

Reducing Energy Consumption

Reducing energy consumption – Why is it important?

One of the most dificult days of every month is when the time comes to pay energy bills, and for most of us they are huge power bills. It is high time, and we need to take serious measures to reduce energy costs. In the following points we will share some important tips will help you to achieve your goals.

How to achieve a reduction of energy consumption?

All the family members should be aware of the importance of saving energy and they should be rewarded if their participation has led to savings.

You should consider some useful actions such as turning off lights when one leaves a room to join some other people in another room or when one moves to dinner at the dining table. Make sure to turn off all appliances, even if you think to be back in a few minutes. Yes, every little action will help a lot. An ocean is made by every little drop of water.

You should turn off the TV or turn the fan off. Just taking care of these these small steps will surely lead us to long-term savings by constantly reducing the energy bills.

Invest wisely in order to save energy

You should also plan some smart investments for power such as replacing all incandescent bulbs present in the house with CFL bulbs or fluorescent lights which consume less energy.

There are useful Power saving gadgets available in the market. They can be used to monitor the total electricity intake in your house and allow you to make rational decisions about how to control their use.

Most of us assume that the growth in electricity bills is due to the large number of electrical items found in the home and that little can be done to reduce energy costs. But the truth is that energy costs are not directly affected by the number of gadgets, but by the way you use them.

Plan actions to reduce energy costs

Take a step forward to control the typical elements that regularly use a lot of power -

• The heating and the air-conditioner should be kept to a minimum high or low temperature.
• The washer should be used only when there is a bucket full of clothes.
• Geyser should be on for maximum time.
• The computer monitor should be turned off when not in use. It consumes maximum power and it only takes a few seconds to turn it on again.

Conclusions

In this way we can save power and benefit the environment that is facing a severe shortage because of high demand.

You can also plan to make power at home with solar and wind energy to replace your power bills. This will also to reduce the requirement for electrical wiring and sockets in your home. Try using renewable energy from natural resources such as wind, solar, tidal power at a lower price, and with beneficial effects on both you and the environment.

How Does Geothermal Energy Work

Geothermal energy is the heat available from the earth. Now this heat can come from two main sources. One, the heat coming from the sun and the other is heat coming from the center of the earth itself.Theoretically speaking the geothermal energy is enough to meet all the energy demands of humans. But this whole heating potential is not extractable.

The top surface of the earth is baked by the sun during the day. The earth conducts this heat underneath the surface. The effect of this is more pronounced during the winters – when the temperatures a few meters underground are 10-15 degrees Celsius.

The other source of geothermal energy is the hot center of our earth. The center of the earth has very high temperature of up to 6000 Celsius. Places which are more prone to volcanic eruption are mostly suitable for extracting geothermal energy. The hot pools and geysers are other apparent forms of geothermal energy at our disposal. The geothermal energy from the center of earth can be extracted by digging for deep pipelines which will require more cost.

The geothermal energy due to absorption of heat from sun rays is more uniform and can be used anywhere. This heat is mostly used to warm up the homes in cold countries.

Different Scandinavian countries have employed methods which make use of this energy.  However the geothermal energy from the earth’s center is more useful when higher temperatures are required; for example, in generating steam for power plant usage.

The water needs to be pumped for circulating through the pipes. This pumping cycle needs electricity or some mechanical power. However it is estimated that you get 2-3 degrees for using one degree equivalent power. This heat can be extracted by laying underground pipes and running water through them.

The water absorbs heat which can be used for different purposes after reaching the earth’s surface. This water can be directly used for floor heating using compressors. The water containing the geothermal energy needs less heat to boil. So this water is more economical in generating steam which in turn can be used for electricity or supplying hot water to buildings. As less fuel is consumed in heating this underground water so the drastic effects on environment can also be reduced.

Hydrogen-Powered Personal Helicopter

A personal helicopter weighing just 230 lb created sizzling news when it flew on hydrogen with zero emission. With an ability to carry payloads up to 800 lbs, this pocket Hercules can fly for 90 minutes. Fitted with easy controls, this reaches a speed of 100 knots thanks to a pair of small yet powerful motors mounted on it. Two common and easily available things – Hydrogen peroxide (H2O2) and a catalyst – combined to bring about a milestone in personal aviation history with attention to the environmental issues as well! Avimech has combined these two to power engine in to an innovative machine.

YouTube: Avimech Dragonfly | More Videos

A unique combination:
Avimech has combined two ideas – a rocket and a helicopter – to create this cute little personal aviation machine baptizing it as ‘Dragonfly.’ Actually this idea to utilize H2O2 and a catalyst has been around for some time. But to use them to power this hybrid version of a rocket in a helicopter is the brain child of Avimech.

Motors at rotor tips:
There are two powerful small motors fitted at rotor tips which resemble rocket nozzles. These nozzles propel the rotors getting power from the reaction of H2O2 with the catalyst. There is no gearbox. There are two fuel tanks to store H2O2. The H2O2 reacts with the catalyst in the rocket nozzles and the reaction powers the rotor nozzles which sets the rotor tips in high-speed motion.

Common ingredients:
Hydrogen peroxide (H2O2) is very safe environmentally and easily available chemical. Usually printing presses are cleaned with H2O2. This commercial-grade H2O2 is diluted and used in the rotor nozzles. The reaction of H2O2 with the catalyst produces the high pressure which sets the blades into motion.

A simple but great machine:
The motors are 8-inch long and they can generate 102 hp which helps the aircraft peak a speed of 100 knots. The H2O2 is diluted to about 50-70%. And when the catalyst reacts with the H2O2, only water vapor gets released and no other harmful emission occurs.

“(ERA) helicopter:”
Acclaimed as the first ever created environmentally responsible aviation (ERA) helicopter, Dragonfly certainly deserves this epithet. Emitting nothing but water vapor and running on only hydrogen- an environmentally safe fuel, this helicopter does not pollute the space with harmful emissions like carbon.

Future plans?
This hydrogen-powered, zero-carbon-emission environmentally friendly but expensive helicopter has been the brainchild of Ricardo Cavalcanti of Avimech. Though at present the engines are not fuel-efficient – guzzling 11 gallons of fuel per hour, the day may not be far off when this is also rectified and a perfect eco-friendly personal aviation machine may be available.
