It's cool work. Some things I've picked out from a quick skim: - Only the downstream turbines gets a boost, cutting gains of a pair in half* - The boost only occurs at night, cutting gains approximately in half again. - Veering winds only occur 75% of the time This already cuts the gains from an ideal 23% to roughly 4.5% real world. I don't see any treatment of incoming wind direction - it appears to only consider pure West to East wind with turbines precisely aligned with the wind. I suspect the effect would disappear as the wind shifted from other directions. While wind is generally westerly in the US, it varies a lot hour-to-hour. Combine this with the above and I'd suspect real-world benefit is in the 1-2% range, at which point the added complexity of maintenance and production probably cancels out the benefit. Not a knock on the research, because it is great work, but it is incomplete. *This may be unfair, as it's unclear what affect multiple in a row would have. But the power production of multiple turbines in a row when the wind is blowing precisely parallel to the row drops off pretty quickly. Commercial turbines are something like 45% efficient these days, so turbine 3 only has ~30% of the original power available.
