What about the main jet turbines? Do they not "free spin" in the event of a power loss? Do they close off the doors. I thought when I first read your post that they ejected the jet engines ha!
When you think about "heat", let's sort of go off topic here... In space "heat" is in the form of electromagnetic radiation right? And it is either extremely hot, or extremely cold due to the absence of an atmosphere so... in regards to a "Heat Engine" what exactly are we talking about here? I mean, do humans "feel" heat because their skin cells or nerve cells are being excited or energy is being added to them by radiation?
When you see depictions of heat, you always see these "waves" I wonder if it is because of the "wave appearance seen when rising heat from for example a fire changes the speed of light and you can see a wavy figure on the ground from something "invisible" the "heat"
I may have confused some topics there but I noticed that today on a barbecue grill

Sorry to bring back an old thread
I was just wondering why most of the commercial generators that I see are vertically oriented?
If an object does not displace height then is there work done on the object? Despite that it is spinning?
The answer might be really simple but I have seen spiral shaped wind turbines like the one featured in the movie "Water World" though I haven't seen these in person. It would seem that this wind turbine design is based on this idea of no vertical displacement eg. the blades don't go up to fight gravity... although since symmetry is involved and when the blades go back down with gravity then maybe there is no net effect of gravity on the turbine?

The need to "overcome gravity" lifting the blade on one side is offset by gravity pulling it down on the other.
Also, what benefit could be had if a wind turbine (horizontal axis) was designed so that the blade tips were magnetic and say a ring was on the outside of the wing tips. Here's a design example.
