It got me thinking, does anybody have a wind power turbine on their bus? I am in the planning stage right now, and trying to figure out my power system. So how about it? Anybody have a turbine on their bus? I assume on the top would create drag and clearance issues, but what about on the front of the grill or low profile ones on the sides? Is this doable? Is there some major reason not to do this that I am overlooking?
I know very little about this, but I think one of the reasons you don't see this more often is that there are generally simpler and cheaper ways to generate power more efficiently/effectively.
Small wind turbines are definitely a thing, and are not uncommon on boats where 'free' wind energy is plentiful, and other options (like solar) are more limited. But from what I understand small wind generators usually generate maybe a couple hundred Watts and many people conclude they are not worth the added complexity.
Wind speeds are higher and more consistent at greater heights, and unlike solar, wind power cannot be switched off, it needs a 'dump load' to dump excess power into.
As for whether you could mount one to the front of your bus and use it while driving, I don't know. I think the questions you would need to answer are (1) would it generate a meaningful amount of power, and (2) would it negatively effect your mpg's, (3) would it be safe and legal at highway speeds.
I still like the concept of multiple free, renewable, and green energy sources, but I'm not sure that the gains justify the costs (in $$'s and in complexity) in our context.
