Arizona State architectural student, identified only as Joe, says his idea is to retrofit horizontal steel structures that currently hold freeway signs with two horizontal-axis wind turbines powered by the turbulence from passing cars. (Joe admits borrowing the turbine design from U.K. based quietrevolution). He figures (without showing figures) that with an average vehicle speed…

UK-based wind-energy company quietrevolution says it will use PLM software from Dassault Systèmes, Paris, to improve design and manufacturing of its wind energy generators. Having calculated a mathematically correct shape for its aerodynamically-optimized vertical axis rotor blades, quietrevolution uses Dassault’s Catia to design, engineer, and manufacture its turbines. The company says Catia helps them capitalize…
