Wind Turbine Tower Design Gives 50 Savings on Steel Expenses
Technology Articles | October 7, 2010 Texas-basedGreenward Technologies develops wind turbine technology that increases windefficiency, minimize steel component necessities, and increase stability.� Therenewable energy company uses a patent pending �ISO-e� tower technology that canlessen the tower�s steel component necessities by as much as 50%.� The reduction would result to a considerabledecrease in the manufacturing cost of towers.�The new technology developed can also make the turbine stronger and moreresistant to buckling malfunction. The�ISO-e� technology of Greenward Technologies is said to be based on theprinciple that a pressurized cylinder can endure much higher bending loads thanits unpressurized counterpart.� The logicbehind the principle is that the pressure steadies the thin steel shell bysustaining its shape, and countering the inward elastic instability thathappens before buckling failure occurs.� The designdeveloped by Greenward Technologies reduces the need for steel
