Energy From Wind

Join: www.fb.com Bored with seeing the same scenery everytime you look out of the window? Check out the Rotating Tower by David Fischer which is a building in which each floor has the capability to rotate on its axis and face a different direction according to the resident’s preferences. In addition the building is able to produce its own energy from wind.

The Atmosphere, the Ocean and Environmental Change (GG 140) Renewable energy sources are discussed. These include wind energy, solar energy, biomass energy and geothermal energy. Energy from wind is acquired through the use of large wind turbines. These turbines ideally need to be located in areas where there is strong wind and low atmospheric turbulence. Solar power is collected using both photovoltaic solar cells and concentrated solar power. Energy from biomass can be produced in two ways: burning biomass to generate electricity or fermentation to produce fuel ethanol. Geothermal energy is produced by pumping water below the earth’s surface into areas of hot rocks which heats the water and creates steam. This steam is then run through a turbine to produce power. 00:00 - Chapter 1. Renewable Energy Sources 02:20 - Chapter 2. Wind Energy 35:19 - Chapter 3. Solar Power 42:18 - Chapter 4.

TransLinkInc asked:

Blade Train Universal Blade Transportation System — TransLink, Inc moves the worlds energy future with leading-edge solutions for transporting dimensional freight, including wind turbine (WTG) components and other large objects. TransLink, Inc. uses state-of-the-art logistics equipment, storeage / laydown facilities, and innovative “Delivery-On-Demand” processes to efficiently move wind turbine blades, towers, and other components by rail or truck, from manufacturer, to laydown/storage facilities throughout the USA, to windfarm sites throughout North America. TransLink’s unique equipment — including the “Blade Train Universal Blade Transportation System.”– , logistics planning and process saves time, labor, and cost, while increasing safety and minimizing component damage. Delivery-On-Demand significantly decreases the total cost of delivery and construction of mechanically-complete wind turbine generators (MC-WTGs) on wind farms throughout North America. TransLink, Inc successfully completed design, fabrication and testing of the dimensional freight company’s Universal Blade Transportation System, featuring a cradle and pivot design. This allows the Blade Train to negotiate turns at well above the 12% maximum curve found in North American rail systems. Unlike other systems, TransLink’s Universal Blade Transportation System is designed for rail shipment of all blades — even on the same train — regardless of manufacturer. This can include blades longer than 65 meters …

Here’s a “tale of two cities” - or two countries, actually. Germany and the United States. One country is preparing for a future in which their children will breathe clean air and lead the worlds economy - and the other is preparing for a future in which their children will choke on polluted air - and fall behind the rest of the world in the global economy. Can you guess which is which? Germany just announced a $260 billion investment in new energy - that’s 8% of their GDP - with a goal of getting 80% of their nation’s energy from wind and solar. This is the largest investment in energy that Germany has made since World War 2 - and they’re even making this investment right in the middle of the financial crisis sweeping Europe - because Germany “gets it.” No nation in the history of the world has ever cut its way to prosperity - just look at Greece. So Germany knows that the only way to get out of this crisis - is to GROW their way out of it - to come out in the end of it a better, stronger, and wealthier nation - through government investments in the future. Germany is going to build offshore wind farms - covering an area six-times larger than the size of New York City. They’re going to put up thousands and thousands of miles in new power lines to modernize their energy grid - enough new smartgrid power lines that, if they were stretched out in a single line, would reach from London all the way to Baghdad. And, prompted by the Fukushima disaster in Japan last year …

Limitations of Wind energy:

No electricity when there is any wind

The limitation of wind power is that no electricity is produced when the wind is not blowing. Thus, it cannot be used as a dependable source of base load power. Utilities and merchant generators will not invest huge sums of money into a technology that does not work when the wind is not blowing. Americans want the lights on when they flip the switch, no questions asked. Wind power will probably increase its market share when we develop a ’smart grid’ that can handle multiple distributed generation input sources of electrical power.

energieag asked:

This video shows one of the many prototypes that I have realized to test my turbine. It is useful to have a car alternator (I used the one of my old fiat) coupled with my TURGO turbine. To tell the truth using a car alternator is not the better thing, due to the low-level performance and to the high number of rpm necessary to start to generate energy. So I advise against the use of it in general. Only in particular cases it could be justified to use it: if you don’t have particular problems of power to be produced, or if the use is really sporadic, its use could be justified. Especially for the easy way to obtain the components, the system shown in the video is very cheap, because it’s realised with recovered materials. If you can listen to the sound of my video, you will listen to my turbine going to high rpm. At a certain moment I will connect the battery and the car alternator will start to produce energy. You will clearly listen that the turbine’s rpm will go stabilizing. This system is now in use in a mountain house coupled to a 75 Watt solar panel. In questo video si vede uno dei tanti prototipi che ho realizzato per il test delle mie turbine. Ho utilizzato un alternatore di macchina (la mi vecchia fiat) accappiato ad una mia turbina TURGO. Occorre subito premettere che utilizzare un alternatore di auto non è la cosa migliore. Per via del basso rendimento dell’alternatore, e del giti alti necessari per far si che inizi a generare. Quindi ne si sconsiglia in generale …

Wind-Mills that Produce Thermo Energy from Wind Power in Southern California James Joher Reporting www.youtube.com/jamestowncalifornia www.youtube.com/jamestownncarolina www.jamestowncalif.com

asked:




Wind is a natural element and it can be a nuisance as well as be a very valuable object that we can use for energy. One of the tools needed to convert wind into energy is through the use of turbines. They are often erected in large open areas where there is nothing to block the wind. A wind mill involves a very tall structure that has a propeller on it. As this propeller continues to turn in the wind more energy is produced.

You will find that wind mills come in a variety of sizes. The early use of wind mills also falls under the category of wind turbines. Many of them are still out there looking very nice. They are historical in nature and they continue to make energy from the wind. Some of them have huge turns on them while others are very basic in nature. Some of the early models of wind mills were used to create enough energy for various types of mills.
