FAQ's

  • At what wind speeds will MAT produce energy?

    • Power Production begins at 9 mph and reaches the rated output at 26 mph. Thermostatically controlled brakes are applied when the wind reaches 45 mph with a resultant drop in power. Beyond that wind speed, wear exceeds the value of the electricity produced. However, MAT can withstand 120 mph winds before destructive forces could be incurred. (Further testing will be required for reasonable long life assurances.)

  • What is MAT's electrical design concept?

    • MAT's generators are standard induction motors just like the ones on your washing machine. We will use 1800 RPM motors. A tachometer relay allows the turbine to cut in at 1800 RPM and a control box stores power using capacitors for an even flow of electricity onto the grid.

  • What happens if one of the blades is damaged?

    • Unlike the large propeller-type turbines which become inoperative upon blade failure, MAT will continue to provide electricity to the grid. In fact, we estimate MAT will continue to send power to the grid efficiently with 6-8 lines disabled.

  • What are the maintenance costs?

    • A structural and mechanical engineering analysis will be completed prior to implementing a scheduled maintenance program which will include bearings, brakes, generators and other moving parts.

  • How much land will each MAT require?

    • We expect MATs to be used in multi-unit arrays. Factoring in wake effects, turbines will be spaced at least 400 feet downwind of each other with 200 feet separation 90° of the prevailing winds. That allows one MAT per acre.

  • MAT has many more moving parts than the giant propeller-type turbines. Is this better?

    • Yes. First, cost is reduced by using more and smaller components. Structural fatigue caused by vibration and lift stresses on huge surfaces is reduced. Also, operation isn't halted if one part fails.

  • Does MAT's design increase construction and maintenance costs?

    • No. Most construction parts are off-the-shelf including the vibration damping bushings. Blades are custom designed but can be mass produced by many vendors, also reducing costs. Repairs are made at ground level rather than atop a huge structure. A roof protects the structure from the elements, reducing wear and tear on the turbine system and also allowing the use of less expensive materials.
