The 1.2٪ figure was a month long average from a real-world test. In certain conditions they got 32% higher efficiency. Presumably those are the conditions when the wind is blowing sub-optimally.
Unrelatedly, from personal experience both onshore and offshore windfarms seem to be packed much tighter than in a line.
- briffle 4y agocompletely anecdotally, I have noticed in the midwest, its very common to have a large grid of windmills. But out west, some (not all) of them are placed along ridgetops in a wide line, with none behind each other.
- dylan604 4y agoWhy go anecdotally? Here's photographic evidence: https://www.google.com/maps/search/wind+farm/@32.3343137,-100.4444907,16289m/data=!3m1!1e3 https://www.google.com/maps/search/wind+farm/@32.3343137,-10...
- koheripbal 4y agoThese rows are spaced far enough apart that I don't think the OP research would help as much. Even where they are clustered, they are at different elevations.
- dylan604 4y agoThat was the point of the prior comment about seeing them strung out vs clustered. Obviously, location location location. West Texas wide open spaces means you can spread them out so they are not ideal candidates. I was just saying that rather than saying something anecdotally, you can make the claim with supporting evidence.
- hinkley 4y agoMost importantly, anything that increases the minimum power production from a wind farm (on “bad days”) reduces the need for base load power. You can only store so much power for interday variations. Everything beyond that takes fossil fuels.
- koheripbal 4y agoI think the minimum remains at 0 - the no-wind today condition.
- im3w1l 4y agoThis made me try to imagine solutions to the no-wind condition, whether there is any control strategy that can work for it. And I laughed at the idea of one wind mill blowing at another to get a net gain of energy. But then I thought, is that really such an absurdity..? What if.. what if you can expend energy to "suck in" a nearby storm for instance? I don't know how viable it would be, but at least it doesn't seem to obviously break physical laws.
- hinkley 4y agoStored hydro is basically this. I’d like to see stored hydro that was a little more environmentally friendly. Perhaps a series of floodgates where one area is mostly dry and another mostly wet, rather than everything being intermittently wet all year.
- sgc 4y agoI get it. You want to store energy in man-made tornadoes, then discharge them slowly when wind calms down. So the optimal layout is circular. By adjusting the turbine, they can either feed into or pull out of the cyclone. Genius!
- HPsquared 4y agoI think it's more like cloud seeding, trying to redirect a weather event (which is happening anyway) to a more fortuitous location.
