It's fair to decide one wants none of what in their feed? My posts?
And how the fuck does it sound to you like the "fact" is "straight" that a dynamo+fanblades+mount cost more energy to produce than they can generate in their lifetimes? Do you see some insanely huge energy requirement I'm missing in the production of fanblades and mounts or do you think dynamos just inherently cost more energy to produce than they can generate? What the absolute fuck?
