Point Roberts, WA - February 22, 2011 - Investorideas.com, a leader in cleantech stock research issues a sector close-up on wind stocks and how two companies are betting on taller wind towers for better efficiencies.
GE (NYSE: GE) recently reported the acquisition of next generation technology from Wind Tower Systems, LLC (WTS) that is expected to enable taller wind turbine towers. According to the press release,: The need for taller, cost-efficient towers is becoming an important factor in the wind industry as blade lengths increase. "
Wind company Clean Wind Energy Tower, Inc (OTCBB:CWET) may be working on one of the tallest wind towers, with a very unique technology . According to Ronald W. Pickett, President and CEO, Chairman, " We create a downdraft inside our tower and the wind spins turbines constantly unlike wind farm turbines on a tower pole which sit and wait for wind to blow.”
Clean Wind Energy, Inc. a wholly owned subsidiary of Clean Wind Energy Tower, Inc, (OTCBB:CWET) is designing and preparing to develop, and construct large "Downdraft Towers” that use benevolent, non-toxic natural elements to generate electricity and clean water economically by integrating and synthesizing numerous proven as well as emerging technologies. In addition to constructing Downdraft Towers in the United States and abroad, the Company intends to establish partnerships at home and abroad to propagate these systems and meet increasing global demand for clean water and electricity.
The Downdraft Tower is a hollow cylinder with a water spray system at the top. Pumps deliver water to the top of the Downdraft Tower to spray a fine mist across the entire opening. The water evaporates and cools the hot dry air at the top. The cooled air is more dense and heavier than the outside warmer air and falls through the cylinder at speeds up to 50 mph, driving the turbines located at the base of the structure. The turbines are attached to generators to produce electricity. The exterior of the Downdraft Tower is constructed with vertical "wind vanes” that run the entire length of the structure. The Downdraft Tower's vanes capture the prevailing wind and channel it through a separate system of tunnels to turn turbines attached to generators that produce additional electrical power. This dual renewable energy resource enhances the capability and productivity of the Clean Wind system.
The Downdraft Tower has the capability of being operated with virtually no carbon footprint, fuel consumption, or waste production and this technology has the potential to generate clean, cost effective and efficient electrical power without the damaging effects caused by using fossil or nuclear fuels, and other conventional power sources. The Company also believes that increasing emphasis on green technologies and governmental incentives in the energy industry should have a positive long-term effect on the Company's planned business and the wind energy industry in general.
The Company has entered into a number of agreements with potential partners to meet the development aspects of the tower. Specifically, three of the largest companies in the world are working with clean wind providing final bids to meet the tower's specifications.
GE Completes Acquisition of Next-Generation Wind Turbine Tower Technology Technology Designed to Allow Taller Towers while Lowering Wind Farm Installation and Transportation Costs
SCHENECTADY , N.Y. - 11 February 2011 - GE (NYSE: GE) announced today the acquisition of next generation technology from Wind Tower Systems, LLC (WTS) that is expected to enable taller wind turbine towers. The need for taller, cost-efficient towers is becoming an important factor in the wind industry as blade lengths increase.
WTS has been working on the development of the space frame tower system technology for use at wind farm sites that require hub heights of 100 meters or more. The space frame tower technology is a highly engineered and optimized structure that will handle the unique static and dynamic loads generated by wind turbines.
WTS also has been developing innovative ways to transport and install these taller wind turbine towers. The space frame technology will use standard flatbed trucks. Hi Jack system technology can eliminate the need for heavy lift cranes during installation. These new technologies offer the ability to cost effectively extend the tower height, which in turn enables the turbine to produce more energy.
"We see great potential in the addition of this technology to our portfolio not only for our customers but also for the wind industry as a whole,” said Victor Abate, vice president-renewable energy for GE Power & Water. "Taller towers are an essential complement to longer blades. Longer blades capture more energy and in turn improve return on investment for wind farm developers.”
"The taller space frame towers and integrated lifting system concepts, developed with the support of the U.S. DOE and California Energy Commission, have been designed to drive lower wind energy costs,” said Thomas Conroy, CEO of Wind Tower Systems. ”We are delighted that the development of the company's products will be completed and commercialized by GE.”
Plans are underway to install a prototype of the GE's space frame tower system technology to validate and test its design later this year with commercial availability targeted for 2012.
GE (NYSE: GE) is an advanced technology, services and finance company taking on the world's toughest challenges. Dedicated to innovation in energy, health, transportation and infrastructure, GE operates in more than 100 countries and employs about 300,000 people worldwide.
