Each 6 foot - tall fan supplies 700 horsepower and allows researchers to
test different wind directions combined with wind -
driven rain, an important variable when assessing infrastructure weaknesses that
occur during hurricanes.
Hybrids brake electrically
during mild braking and transition to mechanical on harder braking or when the propulsion battery is fully charged as
occurs in extended down hill travel so a gentle
test drive around town can obviously not reveal a brake problem.
