Ya sure having it as an alternative is effective and useful.

Yes it may be true that it will harvest low energy than the input of making it. But it's really important to have one of it in case of emergency.

Personally I also like the small-scale devices which harvest energy from the natural things which have no pollution. But I also like to have the answers in numeric forms.

Yes truly if the output is less than they are not very impressive in comparison. At the same time it is a new device which will improve with the passage of time .

Agreed, what you said, plus convenient and less expensive.

OK,  for how many hours will I have to wave my Iphone around to get one minute of airtime?

The micro wind turbine is certainly a remarkable feat of skill, or something.

BUT the question of it recharging any portable electronics is more simply answered. If the efficiency were to be 100% then all we would need to do is find the energy that it has available in an airstream the size of the turbine blade, and determine the current that would provide at a voltage adequate to charge a battery. To make the calculations simpler we assume 100% efficiency in all of the conversions. The answer is that while it may possibly be able to charge a battery for some very low powered monitoring device, such as an outdoor temperature sender, it would be quite worthless for anything similar to a phone of any kind.

Nice try, but no prize. And please don't mislead us with false titles.

All other concerns aside, it seems like they'd be easy to contaminate or destroy with a careless touch.  You'd have to filter the chunks out of air going past them, which would reduce the air velocity and raise the cost of operation, but you'd still have gaseous contaminants that could eventually cause corrosion.  Perhaps the best use would be inside a sealed container with sides that move with barometric pressure change, forcing "wind" through a small orifice and past a tiny field of these.  Like a watch.

Some arithmetic is called-for before deploying these.  The power generated by a small patch of them might be enough to power a watch or a microprocessor in near-standby operation. But I don't think a pocketable patch of these is going to charge up a modern-day cellphone.
