February 27, Wind power is notoriously flighty, particularly at ground level. But a generator situated feet above ground level would enjoy much more consistent strong wind - which is why the Magenn MARS system makes so much sense. Each MARS system will be cheap and portable, which will make them extremely useful in rural, camping and emergency situations. A prototype has successfully been flown in North Carolina. A great idea that makes economic sense. The body of the blimp has fans attached to it to catch wind and generate spin - and once the unit is spinning, it generates extra lift due to the same " Magnus Effect " forces that cause spinning baseballs and golf balls to curve in the air.

So what happend since ? I tried to find some new information, but I'm just able to find information around So I guess this wasnt really a breakthrough innovation?
But why? Post a comment. Almost ALL the financial mistakes that I make are listed in this book! This book shows The Magenn Power Air Rotor System MARS is a patented high altitude lighter-than-air tethered device that rotates about a horizontal axis in response to wind, efficiently generating clean renewable electrical energy at a lower cost than all competing systems. Airborne wind - turbines that fly in the sky and harvest energy from atmospheric wind has the potential, say proponents, of reducing the cost of wind power.
In April of , Magenn Power made history by having the world's first rotating airship. This paper presents an analysis of M. S and its developments. The physical behavior of machine is presented through its components. This system is a highly advanced one that is been not yet implemented till Now Canadian company is taking orders to distribute in in all the leading markets.
This paper also presents a detail view of working and advantages. Wind is the fastest growing energy source in the world and one of the lowest priced renewable energy technologies today, at a cost of cents per killo watt hour.
The wind is a completely renewable source that will last forever. The life cycle for the energy gained from wind turbines is simply as long as the physical parts last.
The generation of electricity from wind power takes place in several steps. Centrifugal blades on the MARS can generate up to several megawatts of clean, renewable energy at a price well below our current grounded wind turbines. An airborne wind turbine is a design concept for a wind turbine that is supported in the air without a tower.
Airborne wind turbines may operate in low or high altitudes; they are part of a wider class of Airborne Wind Energy systems AWE addressed by high altitude wind power. When the generator is on the ground, then the tethered aircraft need not carry the generator mass or have a conductive tether. When the generator is aloft, then a conductive tether would be used to transmit energy to the ground or used aloft or beamed to receivers using microwave or laser.
Airborne turbine systems would have the advantage of tapping an almost constant wind, without requirements for slip rings or yaw mechanism , and without the expense of tower construction. As of , no commercial airborne wind turbines are in regular operation. A tether is a cord or fixture that anchors something movable to a reference point which may be fixed or moving.
Energy generated by a high-altitude system may be used aloft or sent to the ground surface by conducting cables, mechanical force through a tether, rotation of endless line loop, movement of changed chemicals, flow of high pressure gases, flow of low-pressure gases, or laser or microwave power beams. A tether is a long cable usually made of thin strands of high-strength fibers or conducting wires.
The tether can provide a mechanical connection between two space objects that enables the transfer of energy and momentum from one object to the other. The electrical current that is generated travels down the tethering lines to a transformer at the ground station, then is redirected to the power grid. Helium balloon. A Helium balloon is a balloon that stays aloft due to being filled with a gas less dense than air or lighter than air.
Today, balloons include large blimps and small rubber party balloons. Helium balloons work by the same law of buoyancy. As long as the helium plus the balloon is lighter than the air it displaces, the balloon will float in the air.
Helium sustains the Magenn Air Rotor System, which ascends to an altitude as selected by the operator for the best winds. Helium is the chemical element with atomic number 2 and an atomic weight of 4. It is a colorless, odorless, tasteless, non-toxic, inert monatomic gas that heads the noble gas group in the periodic table. Its boiling and melting points are the lowest among the elements and it exists only as a gas except in extreme conditions.
The blades are relatively thin because this means they have a greater surface area to volume ratio and so are affected more by the wind. For a simple demonstration, think of the difference between fanning yourself with a flat piece of paper and a rolled up piece of paper. The flat piece causes a far greater movement of air and the same goes in reverse.
Air movement is going to affect the flat piece much more than the roll, although the weight is the same. The blades are also curved to increase their efficiency. As the blades move they cause a shaft in the body of the wind turbine to start turning. This leads into a gearbox. Gears transmit rotational energy in a similar manner to the cogs in an old fashioned clock.
The gears in the gearbox of a wind turbine end up spinning far faster than the blades were. Wind turbine blades turn at a speed of revolutions per minute, and are equipped with regulators that shut the system down during hazardous weather to avoid having them spin out of control. Blade Specifications: Obviously, this is the one variable that engineers can control. Longer, slimmer and lighter turbine blades can increase energy production.
In his detailed May 5, article, Wind power Engineering Editor Paul Dvorak stresses the importance of turbine blades being as light as possible, yet durable enough to withstand high winds without breaking. Current blades range from feet meters , but future prototypes may be as big as feet meters. There are two types of turbines. One is the vertical-axis type. It works like an egg beater. It works for small power uses: pumping water and grinding grain.
This turbine cannot produce enough energy for electrical purposes. The second turbine is a horizontal axis, which has the capabilities of converting wind into electricity. This is the style used today on wind farms. Turbines will generally last for around , hours, or about years. The Honeywell turbine would measure 57 feet across and carry two one-megawatt turbines.
In 34 MPH winds at 5, feet, the device would travel at miles per hour and generate a megawatt of energy. The generator sits in the back of the device to add stability. This is done by the massive rotor blades, which form the visible part of a wind turbine.
The wind turbine generator converts mechanical energy to electrical energy. Wind turbine generators are a bit unusual, compared to other generating units you ordinarily find attached to the electrical grid. One reason is that the generator has to work with a power source the wind turbine rotor which supplies very fluctuating mechanical power torque.
A generator situated feet above ground level would enjoy much more consistent strong wind - which is why the Magenn MARS system makes so much sense. On large wind turbines above kW the voltage tension generated by the turbine is usually V three-phase alternating current AC.
The current is subsequently sent through a transformer next to the wind turbine or inside the tower to raise the voltage to somewhere between 10, and 30, volts, depending on the standard in the local electrical grid. Large manufacturers will supply both 50 Hz wind turbine models for the electrical grids in most of the world and 60 Hz models for the electrical grid in America.
Generators need cooling while they work. On most turbines this is accomplished by encapsulating the generator in a duct, using a large fan for air cooling, but a few manufacturers use water cooled generators. Water cooled generators may be built more compactly, which also gives some electrical efficiency advantages, but they require a radiator in the nacelle to get rid of the heat from the liquid cooling system.
Working Wind spins a turbine's blades, which, in turn, cause an attached generator to also spin. The wind blows through blades made of fiberglass-reinforced polyester — this makes the blades lightweight and yet strong enough to withstand the force of the wind. The blades change the wind's energy into a rotational shaft energy think of a standard fan. At the other end of the shaft, a gearbox transfers the energy to a secondary shaft.
The step up gearing causes higher revolutions per minute rpm in the secondary shaft and consequently lower torque. A generator or alternator is mounted on the secondary shaft, and converts the mechanical energy originally imparted by the wind to the turbine.
The generator then converts that moving energy of the wind into electricity using electromagnetic induction, which involves using the opposite charges of a magnet to create an electric current. The generators are at each end of the rotor with a direct output power connection to the twin cables. Outboard of the generators at each end of the rotor are wind vane stabilizers in the form of conical wheels.
The deviation in the trajectory of a spinning projectile caused by the Magnus force. The deviation is toward the direction of the spin and results from pressure differentials in the spinning projectile.
Wind causes the blimp to rotate: That movement gets converted into electrical energy and is then transferred down the tether. Instead of the large pinwheel blades that are typical of wind turbines though, the blades of the M. S turbine are actually part of the three-dimensional blimp itself. The blades catch the wind, causing the entire blimp to spin around.
After the generator converts that movement into electricity, it's transferred down the turbine's long tether. Winds at these higher levels are significantly faster than low-level winds because they don't encounter as much resistance from objects on the ground like trees and buildings. Research shows that with each doubling of elevation, there is a 12 percent increase in wind speed with each doubling of wind speed there is an eightfold increase in wind power.
The wind pushes the rotor blades, converting kinetic energy to rotary motion. This spins a low-speed shaft, which turns a gear at the lower end.
The gear in turn drives a smaller gear on a high-speed shaft that runs through generator housing. A magnetic rotor on the high-speed shaft spins inside loops of copper wire that are wound around an iron core.
Magenn Air Rotors: Floating Wind Turbines

The new design from MAGENN Power has many advantages over the conventional wind turbines and diesel generators typically used to produce energy, including cost and environmental benefits. Essentially, it is a little blimp, tethered to an electrical ground station, that generates clean, renewable energy at a low cost.
Magenn floating wind generators take advantage of high altitude winds
Treehugger has shown flying wind turbines before but never one this clever- it is held up by helium. Such a simple idea- it works on both straight lift from the helium and the " Magnus effect " where "For the Magnus airship and hence the patented Magenn Air Rotors System, we have proven that as wind speed increases, rotation increases, lift increases, drag will be minimized because of reduced leaning, and stability increases. Magenn efficiency will be 40 to 50 percent. This is hugely important, since doubling capacity factor cuts the cost of each delivered watt by half. Altitudes from ft to 1,ft above ground level are possible, without having to build an expensive tower, or use a crane to perform maintenance. Mobility is also useful in emergency deployment and disaster relief situations.
