Composite Technology Announces Issuance of Key Patent

Tag: AC Synchronous Generator

Composite Technology Corporation (CTC) (OTCBB: CPTC) announced today that its CTC Cable Corporation subsidiary has been awarded United States Patent 7,368,162. This patent protects key facets of CTC Cable's ACCC* conductor and core, as well as a wide range of potentially competing designs. The United States Patent and Trademark Office officially granted the patent on May 6, 2008. CTC Cable Corporation now holds six United States patents relating to its ACCC conductor, core and hardware accessories, with additional patent applications pending. CTC Cable Corporation is pursuing corresponding patent applications in many other countries throughout the world.

"We are delighted with this patent grant," stated Benton H Wilcoxon, CEO of CTC. "This patent is expected to be of significant value in helping us protect the growing market position for our ACCC conductor and core products."

About CTC:

Composite Technology Corporation, based in Irvine, California, USA, develops, manufactures and sells innovative high performance electrical transmission and renewable energy generation products through its subsidiaries:

--  CTC Cable Corporation produces composite rod for use in its patented  ACCC* (Aluminum Conductor Composite Core) conductors, which are "high efficiency conductors" for use in electrical transmission grid systems. ACCC conductors demonstrate less electricity line losses when compared with conventional conductors and when deployed in place of conventional conductors on existing systems, the higher efficiency of ACCC conductors enables power generators to reduce the amount of power they must generate while still delivering the same power to the customers. They have also demonstrated significant savings in upgrade capital costs and operating expenses when substituted in grid systems for other conductors. ACCC conductors enable grid operators to reduce blackouts and brownouts, providing a 'reserve electrical capacity' by operating at higher temperatures without significant thermal sag of the lines. ACCC conductors are an innovative economical solution for reconductoring power lines, constructing new lines and crossing large spans. ACCC composite core is
delivered to qualified conductor manufacturers worldwide for local ACCC conductor production and resale into local markets.
   
--  DeWind Inc. designs, produces, and sells the DeWind series of wind
    energy turbines, including the new 2 megawatt (MW) D8.2 model available in
    both 60Hz and 50Hz; the 2MW D8 model in 50Hz; and the 1.25MW D6 model in
    50Hz. The new D8.2 has been operating since early 2007 at Cuxhaven,
    Germany, and utilizes the advanced WinDrive® hydrodynamic torque
    converter developed by Voith AG in combination with a synchronous AC
    generator with high voltage output that is connected directly to the grid
    without the use of power conversion electronics. The first 60Hz D8.2 is now
    operating at Sweetwater, Texas, where it will initially be used for
    demonstration to North American customers. DeWind D8.2 turbines are now
    being assembled at TECO Westinghouse Motor Co., in Texas for our North and
    South American customers.
