that windmill is gonna feel sooo foolish when he learns about thermodynamics

You need a dyson fan though.

why wouldn't that work

Assuming there is wind to blow the windmill to get it started THEN when there is enough power the fan will turn on, then making a closed loop. However, there will only be as much power as the fan can give + wind.

It would work, would it? But what use would it be is my question. You'd have to take part of that power to something else to make it useful which would drain the power of the fan BUT if the wind also spun the fan and the windmill then it would allow for more continuous airflow.

NOT OP btw.

Although obviously wrong, these things are still interesting since they force us to test our grasp of the concepts.

REMEMBER FRICTION IS NO EXCUSE.

In this case, I think the Betz Limit partly causes the setup to fail. There is a physical limit to the amount of energy that the windmill can extract from the wind (Although certain diffusers can allow the windmill to exceed the limit by a bit).

So you'll never get all of that energy back that you put into the wind, much less make any energy profit.

how would the extra energy be stored and transported/etc

>>2496551
I assume just like it is now. One cord would go to the fan and the other to however they do it now with plain old windmills.

Would a crossbreed of a windmill and a solar tower work?

>>2496574
Wut. I don't think so.

>>2496578
Why? It would extract energy from fast winds prevalent at one kilometer-height and from the updraft of warm air.
