[Quiz]

Sorry as this will be slightly off tread... it is about drag and utilizing it to get better mpg though. Has anyone heard of the windbelt (humdinger)? I was thinking that it might be possible to utilize a windbelt on the back end of your car in an area of turbulence to supplement a hybrids electrical power. I got the idea while watching the myth busters mpg show with the ford trucks with the tail gates down episode. As they demonstrated a circular airflow in the bed of the truck. if such an airflow could be utilized to power 5 windbelts and gain a 5w output per windbelt for a total of 25w what would that equate to in terms of mpg for the car? i suppose its an incremental change really...
