Does wind ever even produce more value than what it costs to implement?

Not since the invention of steam and petroleum fuel.



Building a large clipper, especially if you were doing it just out of wood (you know, to be more "environmentally friendly" rather than pump out all that nasty gas from smelting ore) would likely cost well into the tens of millions (the Götheborg replica was built nearly 20 years ago and cost $40M then). The load limit (~500-1k tons, I think) means it would take quite a few hauls for it to ever pay for itself.
