Just needs a handlebar mount now
Most of the dangerous places I've been in Africa, Australia, South America and Asia, the wind rarely blew. I'd rather trust my life to a properly engineered hub dynamo.
In any event I just ordered a 305gr 20Ah battery for under ten euro. Seems to me that will recharge a, say, 1500mA satellite phone from 10% to 90% daily for near enough three weeks, anyway long after the cyclist died from injuries, hunger or thirst.
With such a battery in hand, fully charged, why should one need to lug around a wind generator?
