An Electric Fan Into a Wind tunnel?

Something MacGyver in the 90's TV series of the same name, would do. His TV fan moto would generate enough energy to arc weld:)

That DC-DC converter looked familiar. It's the one [mention:a5312e9762dd4699ba5d3876da34ffe5:e9ed411860ed4f2ba0265705b8793d05] tried to tame for a customer, I think: LTC3780 buck boost converter

As he pointed out, yes you can, but no you should not.

It is all about efficiency and power transfer and you just are not going to get much usable power, even if you have a fairly windy location.

Compare what he builds to the big megawatt turbines being used around the world.

If you want a good wind turbine, you need to buy a good wind turbine. Building your own is doable, but you are wasting a lot of efforts others have done to do the job right.

I don't see anything wrong with his work - moving magntetic fields through coils like that will generate AC. It was interesting, although it was a foregone conclusion that it would have poor performance, as he eventually indicated. People looking for a cheap wind turbine generator usually choose an old vehicle alternator, and add a vehicle battery which acts as a gigantic capacitor to store charge and smooth out the DC.

The Fan to Wind Turbine generator vid seemed straight to me.

Simple and reasonable steps and a disappointing conclusion - that's real life !
