However, introduction would require legal acts, supporting projects, and technological innovation. At Kyushu University, a large-scale demonstration facility for a wind power system called the wind-lens turbine was completed at the Ito Campus. While providing power to the campus, tests to increase the scale of the system will be conducted. For the next stage, Professor Yuji Ohya, one of the developers of this system, plans to build an offshore wind farm in Hakata Bay to conduct field tests, and also has a concept to establish a Multi-source offshore energy farm on the Genkai Sea in the future.

Check us out at www.tutorvista.com An energy source is a system which makes energy in a certain way, for instance a hydro-electric station. A hydro-electric station uses the current of the river for the making of electricity. Nowadays we need energy-sources for electricity. Without electricity no computers, no television, no washers. A lot of apparatus would not work without electricity. The three different kinds of energy-sources have their own pros and cons. In this part we give a few of them. •Nuclear power For the generation of nuclear power little raw material is needed to generate a lot of electric energy. This is an advantage, because the supply of the raw material will be enough for quite a time. A very big disadvantage is that the raw material for nuclear power, uranium, is very radio-active. Also the used rods en other used materials stay radio-active for ages. at a nuclear power plant as Tsjernobyl we have seen how dangerous this type of energy-generation can be. This is the major reason why environmental groups (like Greenpeace) are against this form of energy-winning. •Fossil energy The big advantage of fossil energy is that, to generate the energy from the raw material is easy and cheap. Disadvantage is that during the process of combustion a lot of toxic materials comes into the air which causes extra pollution of the atmosphere, these materials also increase the effect of global warming. Another disadvantage of fossil energy is that the supply of fossil ...

Its 'cheaper' for the coal companies to employee five men, explosives and giant machines and use mountaintop removal mining than it is to use traditional underground mining practices which can take five hundred men and much more time. The motivation here is quick, greedy profit. It is clear that mountaintop removal is not beneficial for the environment and surrounding communities. With an increasing demand for cheap energy, we need to tell our banks to invest our money into renewable energy projects.

Question by Yuggs: Can I use a residential well for geothermal energy?
I am building a new house. We have to drill a deep well for water (~500ft). Can this same well be used for geothermal energy as well, or does that have to be on a separate system?

Answer by Mike
You can use your well for both.

In the summer, you can use it to help cool your house, because the water will be relatively cool. You can use a heat exchanger ti transfer the heat from your house to the water in the well.

In the winter you can use it as a souce of heat for a heat pump when the temperature outdoors is colder than the temperature of the water in your well.

It's true in that the only pollution product is water vapor. But it is far from being the cheapest.

The problem is that the only ways that hydrogen can be produced today are expensive and create lots of pollution. Either you use a lot of electricity to electrolyze water, and the source of the electricity may be very polluting, such as coal plants, or, convert natural gas, with lots of CO2 produced as a byproduct.

Answer by oldprof
I don't see QM as a source of energy for a long, long time. For one, no one really understands it. Even the likes of Feynman, who knows something about it, claims to have little insight into the reality, the physics, of QM. Sure, the equations work remarkably well at predicting outcomes, but no one really understands why. Until the whys are answered, I see no chance of harnessing energy from QM.

No one, for example, can really explain how a quantum seems to borrow energy from its environment and then give it back before that environment knows it was borrowed. That's what happens in so-called quantum tunneling where a quantum of seemingly too low energy state suddenly pops through an energy barrier it should not otherwise have been able to do. Go figure.

Or, here's the one I like, why a wave function bearing all possible paths through a split slit experiment should collapse when its associated quantum is detected up stream from the viewing screen and cause the interference bands to disappear. And then a second detection device even further up stream from the first shows the wave function collapsing immediately even there. How the heck does that wave function further upstream know when to collapse to signify the reality path detected further down stream nearer the screen? Down stream is easy to speculate... but upstream?

No, I don't see commercial energy coming from QM for quite some time... if ever. But, once we are able to join the micro physics of QM with the macro physics of relativity, then I can see new forms of energy coming out of that unified model. Perhaps the matter-anti matter drives of Star Trek fame will become a reality.

www.alternativefuelstips.com Common alternative fuels include bio diesel, butanol, ethanol, chemically stored electricity (batteries and fuel cells), methane, natural gas, wood, hydrogen, vegetable oil, biomass, and peanut oil. The term "alternative fuels" usually refers to a source of which energy is renewable. When we say renewable energy it is the energy from renewable sources like wind power, geothermal power, solar power, tidal power, hydro power or thermal depolymerization. There is growing social interest, and an economic and political need for the expansion of alternative fuel sources. This is due to general concerns of sustainability, environmental, economic, and geopolitical reasons. There are two major concerns that are that of rising cost of fuels derived from fossils caused by an era of growing energy usage and of the crisis of global warming. http

Answer by minefinderIn order to generate electricity from geothermal sources, you need a reservoir of water greater than 100°C within a reasonable distance from the surface, usually about 1500 m.

The principle is very simple - drill a hole into the reservoir to tap into the hot water, pump the water to the surface under pressure so it doesn't boil, and then "flash" (release the pressure) the water in a turbine so that the steam spins the turbine to turn a generator and produce electricity.

Answer by minefinder
In order to generate electricity from geothermal sources, you need a reservoir of water greater than 100°C within a reasonable distance from the surface, usually about 1500 m.

The principle is very simple - drill a hole into the reservoir to tap into the hot water, pump the water to the surface under pressure so it doesn't boil, and then "flash" (release the pressure) the water in a turbine so that the steam spins the turbine to turn a generator and produce electricity. Then you capture the steam, condense it, and pump the water back into the reservoir in an injection well, to keep the cycle going.

The "practicality" of geothermal energy depends on several factors:

1. No energy source is practical in a very remote area, so you need to consider the distance to the electrical load, or at least a major transmission line.

2. Geothermal water almost invariably contains a lot of dissolved solids, especially carbonates and sulfates, which tend to precipitate on the pipes and turbines, and that is expensive to clean.

3. Geothermal energy will only work where the Earth's crust is thin enough to have a high geothermal gradient, such as in the Beowawe area of Nevada.

4. The cost per MWH of installed capacity is very high. Not as high as nuclear, but much higher than coal.

However the "fuel" for geothermal energy is free and long lived. It doesn't produce any greenhouse gases.
