Hi Ken, I'm suspicious of anything on the web these days unless there's credible references. In this case it also didn't make sense unless there was a single occurrence where a wind gen was cobbled together in an act of desperation to charge batteries. Nevertheless, I wanted to be certain so obviously I came to the right place. You have to wonder about the motivation for planting

I found a reference (below) that stated, "During the Second World War, small wind generators were used on German U-boats to recharge submarine batteries as a fuel-conserving measure." Given the capacity of the uboat's battery bank, it would have had to been a good sized wind generator to be able to charge in a reasonable amount of time. Does anyone know if there is any truth
