How do you use a geostrophic-wind scale?
A geostrophic wind scale is a graphical device printed in synoptic weather charts available on weather fax or on the internet, like the ones compiled by Bracknell and other weather services. It enables estimation of the geostrophic wind velocity by measuring the distance between the isobars (lines of constant pressure) in the weather chart and plotting this against the geographic latitude in the wind scale. step 1: determine the geographic latitude of the position you want to estimate the geostrophic wind speed for. step 2: measure the distance between the pressure lines (isobars) shown on either side of that position. step 3: choose the correct latitude line in the geostrophic wind scale or interpolate in the scale, using the result of step 1. step 4: plot the distance measured in step 2 on that line. step 5: read the estimated wind speed from the scale, using the curved lines. NOTE that the geostrophic wind is only a theoretical wind flowing parallel to the isobars in the chart. The true wind always is reduced by friction against the earth or sea surface and will be deflected towards the centre of the low pressure system which is circled by the isobars you used.
What is the salary for wind power jobs?
Wind power jobs have a salary that can range widely. Starting salaries can average between $40,000 and $70,000 depending on the specific job. Often times, a wind tech that stays busy can make better than $80,000 year when adding in a per diem pay schedule. Other compensation variables for the wind power industry include health insurance and company work trucks for traveling between locations. To learn more about how to get a job in the wind industry try googling California Wind Tech.
no it is not
Yes it is. The energy in the wind comes from the sun whose light heats the surface of the earth and the atmosphere. It is that heat that ultimately drives the movements of the atmosphere. So the energy in the wind is constantly renewed by new energy from the sun.
What is the biggest wind farm in Europe?
Whitelee, on Eaglesham Moor in Renfrewshire, Scotland, is Europe's biggest onshore wind farm. It has just announced an expansion making its generating capacity rise from 322 MW to 539 MW, increasing the average daily number of homes it is able to power to 300,000. This will make it one of the largest in the world.
The Scottish government aims to have 50% of electricity from renewable sources by 2020.
A WWF Scotland report last year claimed that, by 2030, renewable energy could meet between 60 per cent and 143 per cent of Scotland's projected annual electricity demand.
How do you make a working model of elevator?
A working model an elevator can easily be fabricated through toys, wheels, weights string, basic hardware, and woodworking skills. An L shape frame can be built with a turning pulley on top. This will resemble a small crane. A strong yarn or wire will run through the pulley. On one side it will be secured to a counterweight, and on the other a block. The block will be demonstrative of an actual elevator's cargo being lifted. Through these common items a working model of an elevator in principal can be built.
How do you get thunderfury blessed blade of the wind seeker?
This questline begins with the killing of one of two bosses in Molten Core, called Baron Geddon and Garr. One drops the Left Bindings of the Windseeker, the other the Right Bindings of the Windseeker.
This leads to a long questline involving ancient history and rare ores, until it leads you to Silithus. You are expected to slay an Elemental Lord called Thunderaan, to be rewarded with Thunderfury, Blessed Blade of the Windseekers.
Once the quest was restricted to Warriors, Paladins and Rogues, but in patch 3.1.1, the quest was made available to any class.
Why are wind turbines three bladed when more blades should catch more wind?
the reason there is only three blades is because four blades would add weight and wind resistance, in some countries they use two or four bladed turbines though.

What are 7 cells that uses energy?
1.Bone cells(Osteocytes) They are the toughest body Cell as they are bound together by calcium and phosphate. As you knows they give strength, support and frame-work to the body by enclosing organs in skeletal system i.e bones.
2. Cartilage cells(chondrocytes)- These cells are similar to bone cells but the surrounding material is just loose and flexible compared to those of bone cells. Hence they are freely bendable. They are present in ear bone (hence ears are fold-able), in between large bones to help them bend and move freely like in between two ribs, spinal bones, joints etc.
3. Nerve cells: These cells are very long and have many branching at either ends. Their specialty is they never multiply in one's life time.They are present all over the body and are sometimes as long as few meters long. They are human brain cells and are found in plenty in brain and the spinal cord and form the nervous tissue.

4. Epithelial cell: These cells are very simple cells which form covering of other cells. These cells form covering layers of all the organs and hence are preset in skin, scalp, respiratory tract, in the buccal cavity surface etc. Ex: Skin cells, mucous cells.
5.Muscle cells: These cells are of muscle tissue mostly long, large and have ability to contract and relax providing movements. They are three types as skeletal, cardiac and smooth muscles.
- Skeletal muscles cells are attached to long bones and assist in their movement (by muscle contraction).
- Cardiac muscles cells are present only in heart muscle and responsible for heart beats.

- Smooth muscle cells are flexible yet, can contract and relax and are present in stomach, intestine, blood vessel walls (vascular tissue) etc. helping in movement of food through the gut.

6 Secretory cell: These cells as name indicates are secretory in nature. They form glands and secrete something important ex; pancreatic cells which secrete insulin, glucagon, salivary gland secrete salivary amylase, sebaceous gland secrete oil on the skin etc.They are found in all secretory organs.
7.Adipose cells: These are fat cells and are storage in nature to store fat. Especially seen in the soles, palms, bums etc. They reduce friction to the body.
8. Blood cells: These cells include RBC's, WBC, Thormbocytes etc. They are always motile and never stay in one place. They have limited life span and they never multiply to form new cells. instead new cells are formed from other cells.
How many feet wide is a wind turbine?
Wind turbine vary enormously in size from a small turbine on a boat with blades about two feet in diameter to large industrial 'wind farms' the blades of which are individually dozens of feet long
Are there hidden environmental and social costs for wind energy?
noise is a big one and associated with health problems. Another would be the birds that are killed when struck by the blades
Can wind be a problem on an over pass?
Yes
************
The wind causes a turbulance as it passes over the over-pass. It has been known to blow over high sided trucks.
Sirs I own an 2000 Toyota RAB4 and my ECT PWR light just came on, what do I need to do? is it ok to keep on driving it? or? Thanks Carlo Bello
What is cheapest wind water or solar energy?
Solar energy is the cheapest because it is free once you have bought the solar panels and after it is installed.
Why is wind energy described as clean energy?
Wind energy is considered as clean energy from the view point that wind power plants do not emit in the course of power production pollutants to the environment as carbon oxides, sulfur oxides, ashes, heavy metals, ... etc. However, wind energy is not 100% clean through the full wind power plant cycle length from the manufacturing of wind power plants components; their transport to site, maintenance, ..., until decommissioning.
What types of wind chimes is there?
Chimes are made by a variety of different companies, in a variety of different shapes, sizes and materials. The answer being, therefor, that there are thousands of types of wind chimes-- since their invention, so many different varieties have been created. In the related links I've included a wind chime buyers guide which details several varieties, and describes what their benefits are.
What is the initial energy source for ocean currents and winds?
Wind is caused by the alternating highs and lows of air. Hot air rises to create a high, cool air sinks to create a low. Ocean waves are caused by the moon's gravity.
Wind can be used to pump water from wells AND/OR generate electricity. Wind-powered boats or ships are called SAILboats. Hot air balloons are driven by the wind. There are even wind turbine powered sailboats. Sailplanes (gliders) soar AND glide on the wind. Plus, we breathe it. Without aspiration, plants and tress would suffocate. In many cases, this requires wind movement.
How much does a 3MW wind turbine cost?
Refer to the "2008 Wind Technologies Market Report", issued by the Department of Energy in July 2009 (http://eetd.lbl.gov/EA/emp/reports/2008-wind-technologies.pdf). $1.3M per megawatt is right on (for 2008 data).

Hi:
I asked the company Vestas this question. They are number two in the world in producing wind turbines. They told me the answer is based on a thousand factors but that the general rule of thumb is that wind turbines cost 1.3 to 1.5 million per megawatt.
Cheers,
Ben
Will the sagamore bridge close because of high wind?
Yes. If the wind gets over 70 miles an hour. Check with State Police.
If a 17 foot wind turbine can produce 3 Kwatts is that per day or hour or minutes?
3 Kilowatts is a measure of electrical power and means the wind turbine produces 3,000 joules per second. So the question is fairly meaningless, assuming the wind is at the right speed it will be producing 3kW every second, every hour and every day!
What is increasing most in China - coal energy or wind energy?
In 2012, for the first time, China increased its wind power production more than its coal power production!
- Coal power production rose by 0.3%, an addition of roughly 12 terawatt hours (TWh) more electricity.
- Wind power rose by about 26 TWh. This increases China's wind energy to 100TWh, putting it in third place after coal and hydro, and larger than nuclear in fourth place.
Why is Renewable energy good for us and your environment?
Because the energy is not releasing harmful gases like co2 and methane into the enviroment.
