Wind Turbine 1888 by Charles Brush

charles_brush-wind-turbine

Charles F. Brush’s 60 foot, 80,000 pound turbine that supplied 12kW of power to 350 incandescent lights, 2 arc lights, and a number of motors at his home for 20 years. It today is believed to be the first automatically operating wind turbine for electricity generation and was built in the winter of 1887 – 1888 in his back yard. Its rotor was 17 meters in diameter. The large rectangular shape to the left of the rotor is the vane, used to move the blades into the wind. The dynamo turned 50 times for every revolution of the blades and charged a dozen batteries each with 34 cells. For scale, note gardener pushing lawnmower underneath and to right of the turbine.

Super-Windmills

super_windmills

Around 1940 in the US, it was announced that ‘Plans were being made to harness mankind’s oldest and cheapest source of power for industry by means of huge aero generators’.

Further, it went that ‘The next few years might see a great change in the landscape of our country. In certain strategic areas which promise a constant, strong wind such as in mountain passes, will grow strange structures resembling the Martian machines of H. G. Wells. But these will be instruments of construction, rather than destruction. These are tall steel towers to which supporting propeller fans are being assembled to convert wind energy into electrical power’.

Little did they know how far the pressure of moving away from generating power by means of burning fossil fuels will bring us in the new millennium?

In 1941, a full-scale futuristic looking wind turbine was built on a mountain top in Vermont and hooked up to the system of the Vermont Public Service Corporation as an auxiliary power source. Mounted on a 110 foot steel tower, its twin 56-foot blades were designed to develop 1,2Kw at a wind velocity of 30 mph. Under favourable conditions, it actually developed 1,4Kw. Although a practical success, structural and financial difficulties ended the experiment. This amazing futuristic design could even withhold any criticism from today’s contemporary wind turbine designers.

Classic ‘Dutch Style’ Wind Mills

dutch-wind-mills

The first fact people recall about The Netherlands as a country is of course its ‘Windmills’. Windmills have been built in The Netherlands for many centuries. In the beginning, the mills were developed for corn milling, land drainage, saw milling and for many other industrial purposes.

dutch-wind-mills-2

Dutch wind mills are actually in many ways quite primitive. Only using canvas sails and turned to the direction from where the wind was coming from by hand. Quite different to the automated mechanisms that can also be seen below which were developed for English windmills which included fantails and shuttered sails.

dutch-wind-mills-4

There are still a very pleasing number of functioning remaining windmills in the Netherlands and even a set of ‘Dutch Style’ Windmills in the US to be seen in the Golden Gate Park in San Francisco, CA.

dutch-wind-mills-5

The number of operating mills in The Netherlands is currently about 1200 and rising, in that the Dutch only count complete workable mills, and in the past years, many extensive rebuilds have occurred to add to this number. Aren’t they just beautiful?

World’s Biggest Wind Turbine

enercon-e126-002

Currently the biggest and most powerful wind turbine in the world is the Enercon E-126 wind turbine (pictured above) generating 6Mw.

The Crown Estate of England certainly knows from which direction the wind blows and has decided to acquire the prototype of the world’s (yet to come) biggest wind turbine, The Clipper 7.5Mw (megawatt) MBE turbine, also known as the Britannia.

There is no current picture available for the Britannia 7.5Mw Clipper and the previous record was held as mentioned before by the Enercon E-126 wind turbine which is rated at 6 megawatt, but can produce around 7 in real world conditions.

While the Enercon is land-based, the Britannia will be located in deep waters near the UK. This makes sense because the marine interests of The Crown Estate include almost the entire UK territorial seabed out to 12 nautical miles, about 55% of the UK’s coastal foreshore, and rights to lease seabed for the generation of renewable energy on the continental shelf within the Renewable Energy Zone which extends out to approximately 200 nautical miles. A giant in the world of wind turbines, which is setting an example to all other large wind turbine manufacturers around the globe.

The MagLev – A Magnetically Levitated Wind Turbine

maglev_wind_turbine

The MadLev is a magnetically levitated wind turbine that can generate one Gigawatt of power (enough to power 750,000 homes) and delivers clean power for less than one cent per kilowatt hour using this wind turbine.

Magnetic levitation is a very efficient method of capturing wind energy. The blades of the turbine are suspended on a cushion of air, and the energy is directed to linear generators with minimal fiction losses. But the big advantage with maglev is that it reduces maintenance costs, and increases the lifespan of the generator. The manufacturer claims that it requires less land space than hundreds of conventional turbines. The MagLev wind turbine was invented by Ed Mazur, a researcher of variable renewable energy sources since 1981. There are already several MagLev wind turbines in operation in China.

“I sit by the window and watch the breeze
tingle the leaves on all the trees.

I sit by the window and hear the wind sing,
carrying spring, making air ring.

Wind! Wind! Blow me a song. Toss me a ship from the sea.
Fling me a willow tree tall and strong. Whirl the world closer to me”.

By Mimi Drodsky

The M.A.R.S.

mars-wind-turbine

The M.A.R.S. (Magenn Power Air Rotor System) is an interesting device that is capable of harnessing the power of the wind (pretty much like how a windmill works) to generate electricity, sending that power down a 330 meter tether rope for immediate consumption. Since the M.A.R.S. is filled with helium, it is capable of flying much higher than other wind turbines in order to gain access to higher wind speeds. The 4.0 kW unit will enter production this year, with another 7 more models in the pipeline which will be released within the next four years.

“The wind has lots of noises.
It sniffs, it puffs, it whines,
it rumbles like an ocean through junipers and pines,
it whispers in the windows, it howls, it sings, it hums –
it tells you VERY PLAINLY every time it comes”

Helical Structured Wind Turbine

space-age-windmills

Helical structured wind turbines are the future of wind mill technology. These amazingly unique looking twists and turns will replace those long and boring blades which represent the conventional image of a windmill. These new and sleek looking windmills are designed much like the old ones when it comes to converting their circular motion in to mechanical work, but it is the structural design that makes them unique and special. In fact, they logically should function better than the traditional windmills as the helical structures seems to not just utilize the energy of the wind, but maximize it by containing the wind.

“The wind came out to play one day.
He swept the clouds out of his way.
He blew the leaves and away they flew.
The trees bent low and their branches did too!
The wind blew the great big ships at sea.
The wind blew the kite away from me.”

Phillipe Starck’s Home Windmill

starck-mill

Wind power going glam. Top designer Starcks’ ingenuity and eye for design has emerged into a unique and stylish home wind turbine like we have never seen before. These so called windmills are part of “Democratic Ecology”, a line that Starck has developed with an Italian Industrial group. “It’s part of what we love so much about his designs – the marriage of beauty, function and responsibility.” “Ecology is not just an urgency of the economy and protection of our world but also creativity and elegance” says Philippe Starck.

Made from the same transparent material also used in the very familiar Louis Ghost Chair, these clever contraptions are able to generate 20—60% of a home’s energy needs. In addition to looking like a piece of Gucci jewellery, they are relatively inexpensive.

“The wind is pushing against the trees,
He’ll take off your hat without asking you “please”,
He rattles the windows and puffs at a cloud,
Then scoots down the chimney and laughs aloud.”

The Loopwing

loop-wing

This is the “LoopWing”. Another futuristic and experimental looking wind turbine designed and manufactured in the East. It was unveiled in Japan’s Eco-Products 2006 Exhibition. The E1500 model turbine is a home windmill and sports a very unique wing design that operates with low vibration and at wind speeds as low as 1.6 m/sec. The efficiency specs on the turbine are vague — “43% power performance at optimum wind speeds”.

Urban Turbines – “Quiet Revolution”

Urban Wind Turbines

Many people think wind turbines are ugly but what about these unique and colourful residential street wind turbines? Conventional turbines are best suited to wide open spaces where there’s plenty of wind. So this nifty vertical axis, helical design is a much better solution for urban settings.

The Queen of England seems to agree. XCO2, a UK company behind the unconventional design, has applied for planning permission to build one outside her London residence, Buckingham Palace.

The “Quiet Revolution” turbine has 5-metre-tall blades which can generate 10Kw-hours of energy from a mean annual wind speed of just 5.8 metres per second. Embedded LEDs in each S-shaped blade are used to create images as the turbine turns. It is rumoured that the ones to be installed at Buckingham Palace may be used to display a glowing union flag.

The V-LIM – A Rooftop Wind turbine

lim_face1

The V-LIM is a vibration free, silent, self indexing, high-bandwidth wind turbine suitable for rooftop mounting.

Rogue River Wind and Portland State University Maseeh College of Engineering and Computer Science, have joined forces to optimize power generation from a high efficiency wind turbine suitable for rooftop mounting. Pictured here, this twelve foot, self indexing turbine can produce 3Kw at 15mph winds. The turbine is unaffected by air turbulence that can adversely affect most open bladed designs allowing rooftop mounting without tall towers. The turbine is silent, vibration free and can be screened to prevent harm to birds and other wildlife. The turbine can be used in both rural and urban locations with good wind resource. Due to its unusual design (looking more like a large motorbike wheel with white tyres rather than a wind turbine) it was without question that we had to include this amazing looking piece of engineering into this collection of the most amazing windmills of the world.

Sky Serpent – An Array of Small Rotors

sky-serpent-wind-turbine1

Doug Selsam’s Sky Serpent uses an array of small rotors to catch more wind for less money. The key to increasing efficiency is to make sure each rotor catches its own fresh flow of wind and not just the wake from the one next to it, as previous multi-rotor turbines have done. That requires figuring out the optimal angle for the shaft in relation to the wind and the ideal spacing between the rotors. The payoff is machines that use one tenth the blade material of today’s mega-turbines yet produce the same wattage. A wonderful and controversial design of which the inventor says “This is a 1,000 year-old design” of the single-bladed turbine, “I knew if I could get more rotors, I could get more power.”

The ‘Jellyfish’ Micro Turbine

jellyfish

At a mere 36 inches tall, the Jellyfish plug-in wind appliance can generate about 40 kilowatt hours each month, that’s enough to light a home using high-efficiency bulbs.

The Jellyfish Wind Appliance consists of the following parts:

A vertical-axis wind turbine (VAWT)
A solid-state controller
A variable-speed induction generator

In order to reduce the demand for costly transmission infrastructures, the Jellyfish can work in tandem with the existing power grid and can deliver power exactly where it is needed. Although micro-wind is nothing new, at $400 a pop, the Jellyfish’s price, design and simplicity makes this micro turbine product a fresh face in the market.

The Highway Turbine

highway-wind-turbine

This is a very novel way of re-capturing some of the energy expended by vehicles moving at high speeds on our nations highways which is being proposed by an Arizona State University. Knowingly, air turbulence is generated by vehicles moving at speed particularly trucks and the proposal would involve mounting horizontal wind turbines above the roadway that would be driven by the moving air generated by the passing traffic. The electricity generated by spinning these turbines could be fed back into the grid. Analysis indicate that based on vehicle speeds of 70 mph each turbine could produce 9,600 kWh per year.

These wind turbines are of a quiet running type. In many built up areas there is enough constant traffic volume to maintain a steady airflow through much of the day. The big question that needs to be answered is whether the nature of the turbulent airflow could keep the turbines turning.

“I still get wildly enthusiastic about little things… I play with leaves. I skip down the street and run against the wind.”

Broadstar AeroCam

broadstar-wind-turbine

The Broadstar’s AeroCam turbine design is an absolute head-turner. The design is based on principles first established by the French aeronautical engineer Georges Jean Marie Darrieus (1888-1979), who invented a wind turbine capable of operating from any direction and under adverse weather conditions. Darrieus machines typically have a vertical axis, whereas the AeroCam design has a horizontal axis with multiple blades, giving it the appearance of a water wheel. The major innovation in the design, however, is the ability to automatically and interactively adjust the pitch or angle of attack of the aerodynamic blades as the turbine rotates, thereby optimizing its performance for much the same reasons a bird changes the shape of its wing in flight.

The ‘Nano Skin’ Spiral Twist Wind Turbine

nanoskin-wind-turbine

Agustin Otegu, the inventor of the ‘Nano Skin’ wind turbine thinks that the future of green buildings lies not in the giant wind turbines we’ve seen in so many other projects, nor in huge solar panels. Instead his new design proposal, called Nano-vent Skin, would incorporate tiny, biological self-repairing wind turbines into the outer layer of a building. As wind played over the building’s “skin,” the turbines would spin and create energy that would be fed into the building’s electrical grid. They would also absorb carbon dioxide.

Otegu says: “The outer skin of the structure absorbs sunlight through an organic photovoltaic skin and transfers it to the nano-fibers inside the nano-wires which then is sent to storage units at the end of each panel. Each turbine on the panel generates energy by chemical reactions on each end where it makes contact with the structure. Polarized organisms are responsible for this process on every turbine’s turn. The inner skin of each turbine works as a filter absorbing CO2 from the environment as wind passes through it.” Quite an amazing invention we think.

The ‘Helix’ Wind Turbine

helix-wind-turbine-2

A new breed of vertical axis wind turbine (VAWT) from Helix Wind offers a promising design that may change the way we do wind at home. The Helix Wind Savonious 2.0 uses a unique rotor capable of capturing omni-directional winds to provide quieter, kinder small wind power for your urban home.

The Helix S322 is compact, elegant, sophisticated and versatile. It provides smooth power and torque delivery across a broad range of wind speeds and under the most difficult of physical environments. No furling or shutting down, simple to install, modular and scalable, the S322 is ideally designed for urban environments, low draw, off-grid applications and liquids pumping. This turbine is very captivating to the eye indeed.

The ‘Dutch Windmill Tree’

dutch-windmill-tree

Dutch company One Architecture, Ton Matton and NL Architects were commissioned by the Dutch government for a next generation windmill. The proposed mill is shaped like a tree and can hold up to 8 turbines and be as high as 120 meters! The Dutch government feels that tree shaped mills are less intrusive in the flat Dutch landscape than the mill-parks they use.

The ‘Bahrain World Trade Centre’ Turbines

bahrain-wtc

The Atkins designed Bahrain World Trade Center (BWTC) made history when the three turbines which are allocated between the two adjourning towers were turned together for the first time.

The three 29m-diameter turbine blades on Bahrain’s iconic landmark are the first in the world to be integrated on such a scale into a commercial development and are forecast to provide the equivalent of 11-15% of the power for the two towers when fully operational. “Having all three turbines spinning simultaneously represents an historic achievement for this landmark project and Atkins is excited to have been a major player in turning the original idea into reality” says Simha LytheRao Senior Project Manager for Atkins in Bahrain.”

bahrain-wtc-wind-turbines

The BWTC design blends maritime aesthetics with the functionality of traditional wind-towers. The visually striking sail-shaped towers form a commanding silhouette on the skyline of Manama, and serve to channel the strong on-shore winds directly onto the three spinning blades.
