Re: [FRIAM] Trees as wind farms.
Building on Eric's point that trees are not energy limited, I can almost hear the trees responding to you, Nick. "Dear boy, we ARE but the wind incarnate. And we return to wind in a quick exhale" consider the dual bidirectional chemical reaction of photosynthesis on left and combustion on the right. combustion or slower respiration. CO2 + H2O <=> C6H12O6 + O2 left to right, we have low entropy ultraviolet light with carbon dioxide and water becoming the tree (the carbohydrate/glucose) literally out of the air and putting out oxygen. As you watch this NASA simulation of CO2 for year (https://www.youtube.com/watch?v=x1SgmFa0r04) trees sucking in the air (wind) and forming themselves in the spring in the northern hemisphere. Imagine two other visualizations of what's happening with the water vapor and oxygen along with the CO2 visualization In the summer, when the oxygen is now plentiful, the reaction reverses and the trees literally become winds of CO2 and Steam (later condensing high into water) putting out higher entropy infrared. Note Africa spewing out CO2 and Water with 70% of the global area burned. __ Stephen Guerin Harvard Earth and Planetary Sciences Visualization Research and Teaching Lab stephengue...@fas.harvard.edu mobile: (505) 577-5828 On Tue, Jun 27, 2023 at 7:00 PM Nicholas Thompson wrote: > Thanks, Eric.

Re: [FRIAM] Trees as wind farms.
My guess would be that plants are not energy-limited. At the scale of a leaf on a tree in a forest, or a fiber in a tassel on a wheat-blade in a field, the delivery rate for wind energy is some tiny number — I won’t try to give it here, because I will surely get it wrong — in contrast to light-harvesting, which is capturing and trying to hang onto little hand grenades. (The energy in any visible photon is about 10x the bond energy of the strongest C-C bonds, so just catching these things and not breaking the molecule is one of biology’s major innovations.) So it may be that the complexity of using wind is large enough, and the reward for the energy any given mechanism might harvest small enough, that it just never takes. One could go into a long harangue about the various evidences that plants are not energy-limited, just because they are a delightful enlightening window on the biology around us, but it doesn’t really add to the main point in the last paragraph (the way plants have moved everything onto sugar chemistry because they are nitrogen limited, the ways C4 plants concentrate carbonates because they are water-limited, or the fact that green is blue in NM because they already have more light than they can use at the water levels of high desert and mountains). Interestingly, the chemical free energy that wind delivers by evaporating water and then moving it away from the leaf surface is probably larger than the mechanical energy of twirling the leaf, though again I should provide numbers if I want to make this guess. Or maybe you are already right: that the twirling of the leaf is an evolved property somehow using the mechanical energy, and we just don’t know the literature well enough to know if this observation has been developed. I know the above isn’t a great argument, as it is reasonable to harvest big energy packages to do big jobs, and small energy packages to do smaller jobs, within the same system. But maybe (?) we would have to go outside energy as a simple currency to understand what is or what is not captured? I do think your example of water pumping is a compelling one, since we know the problem is hard and plants need a solution, and we know from things like leg-contractions to pump blood in mammals, that other organisms capture mechanical energy sometimes when it is available.

[FRIAM] Trees as wind farms.
Sitting here at the farm, watching the Normandy poplars bend in the Southeast wind, I am led to wonder why trees don’t make use of wind energy.
