We Can Do Better Introducing a Revolutionary New Wind Turbine Blade Design

In wind power, the goal is to convert wind force into usable energy. The faster the wind blows, the more energy is available.

But to maximize wind force efficiency, wouldn't it make sense to extract as much wind passing through a given area as possible. With current wind turbine blade designs, only the outer 30% of a blade produces any meaningful torque and the blades are less than 5% of the total disk area?

Indeed the physics of conventional wind turbine design are seriously flawed...

MAX-V Turbine Technology

But what if wind turbine blades were designed to utilize 100% of surface area, not only to extract wind passing through, but to divert or accelerate the air prior to extraction? In other words, why not utilize drag as well?

Total blade area isn't the whole story...

The blades of a present-day wind turbine are similar to those of an airplane propeller. So think about wind hitting an airplane. In aviation, drag must be minimized to increase performance. The faster an aircraft goes, the more drag is created and the more fuel is used. An aircraft has to penetrate air efficiently. This is why long thin wings are used by sailplanes. They are designed to maximize efficient penetration without an engine.

Drag is a good thing!

Yet the current wind turbine industry doesn't even factor drag into the efficiency equation.

The common placement of turbines on mountain ridges is ironically a good example of converting drag to energy. Wind is forced to go over the ridge, thereby compressing and accelerating the air.

Replacing current blades with the Max-V blade design means more energy...

By placing a wind turbine near the top of a ridge, it becomes obvious that a fixed obstacle (drag) can efficiently increase the amount of energy available.

In simplest terms, the goal is to accelerate every available molecule and direct it to the region of greatest leverage at maximum velocity like the outside ring of a rotating turbine in this example and model...

This is the beauty of the Max-V Turbine design.

Imagine a wind turbine that produces 10 times more power with far less wind than conventional wind turbines. Indeed the Max-V proof-of-concept technology was found to operate in wind speeds below 1 mile per hour (1.6 kph) even when under load. This is unheard of with conventional wind turbines as they typically only cut-in at around 8 mph. The implications of this factor alone warrants further research and development.

In the 4' model above, the flat plate obstacle is the “ridge”, forcing air to divert and accelerate before passing through the energy extraction blades at the perimeter – the area of maximum leverage. The more the air is accelerated and focused, the more energy is available. Additionally, by creating a low pressure void behind the obstacle such as use of a cone like below, air can be accelerated even more. Yet again, the only penalty for doing so is drag, which is compensated for by anchoring to the ground.

Thus the Max-V design allows for smaller, lighter and cheaper turbines to be manufactured when compared with conventional wind turbines of the same output.

With Max-V Technology, the wind turbine landscape is looking clearer...

MAX-V IMPACT

Applications

The efficiency and scalability of the Max-V means the technology can be applied not just for industrial use but also residential and commercial applications. Both first and third world countries can benefit from the technology with greater power output, easy portability and installation, environmental benefits and lower manufacturing costs resulting in cheaper electricity!

Applications include small, lightweight, collapsible portable turbines

Extracting Energy from Rivers and Tides

The Max-V Turbine has the potential to revolutionize the wind AND hydro turbine industries. Water is 780 times more dense that air, so it can produce far more electricity for the same size. And water can't compress like air, thus any constriction in water flow is translated directly into increased velocity. Constrict a wide slow river into a narrow channel and by focusing all that force towards a point of maximum leverage in the Max-V blade design, the results are powerful and predicable. Thus hydro power can be more reliable and more productive than wind with rivers running year-round.

Hydro power can be more reliable and more productive than wind, with rivers running year-round.
"For both the wind and hydro industries, the Max-V blade technology offers far more energy extracted at far lower cost and effort using both lift AND drag to achieve useful force." - Mike Waters, Max-V designer

DEVELOPMENT

Preliminary third-party test figures have already confirmed the potential of this revolutionary Max-V Turbine design. Now it’s time for World Harmony to bring it to humanity. Like all World Harmony energy projects in development, the Max-V Turbine technology meets an important win/win/win principle given these features:

  • Bridging Technology
  • Easy to introduce to “the market”
  • Simple rather than complex
  • Suitable for home and commercial use
  • Inexpensive to manufacture and affordable for users
  • Easily obtainable raw materials
  • Applicable in all climates
  • Non-threatening to “the establishment”
  • Broad Applications
  • Scalable

Preliminary funding for this turbine technology project will support the goals of:

  • Optimizing the blade design
  • Performing further wind and water tests
  • Coupling the turbine to different types of generators and test
  • Building production prototypes
  • Comparing test results with conventional wind generators
  • Arranging more advanced third-party testing (e.g. university).

World Harmony’s goal is to develop the innovative Max-V Turbine technology, with the potential to sell non-exclusive licenses of the patented blade design to generator manufacturers, especially in the wind and water turbine industry. We would also consider partnering to build a cost-effective generator of which there are numerous opportunities.
