Brookstone Partners is raising capital in order to start building this wind farm, which will take a considerable amount of time. By the time they finally have managed to build the farm (which is by no means a guarantee that it will happen) the difficulty has gone up a lot already, which will eat away a lot of their profits, and then what? Investors have high expectations and thus expect proper returns, because that's why they invest in this industry in the first place.
An idea is worth a buck, for the effort, nothing more.
Yeah, its sounds quite speculative. It reminds me a bit of the mindset of 2008-2010. Where I lived, there were massive construction developments everywhere. And just a couple years later, there were unfinished/abandoned construction projects everywhere.
This industry moves too damn quick to be planning for difficulty adjustments this far in advance -- this is apparently a 20-30 year infrastructure investment. And analysts also say the power is intermittent (unlikely to run at full capacity without good luck).
I've seen better investment plans, that's for sure.
