Make the Drought Evaporate!
~ desalinate with <5% the energy & equipment ~ TL;DR — We need to stop droughts, especially as climate change makes them worse. Desalination is nice, capturing clean water from the sea, yet it requires expensive equipment and lots and lots of energy. We can, instead, accelerate evaporation OUT into the air above our heads! We won’t be ‘capturing’ that clean water — it just rains-down miles away. Perfect, because we don’t need pipes and pumps to transport it! Using this sort of design, we can end droughts and re-take the land captured by deserts in recent decades, cheaply and quickly. The Concept Imagine you have a bowl of salty sea water, with a tiny hole at the bottom. The sea water is slowly dribbling out of that hole, into another bowl beneath, to then get pumped back up to the top. At that dribbling spout, you hang a loose, fuzzy length of yarn, straight down. The water is held against that yarn by surface tension, scuttling down along its surface. As the wind blows past your wet-yarn-wick, it will cause evaporation from that surface, adding humidity to the air, to come back down as rain further downwind. (Place the evaporators geographically so that the wind carries the water to the general spot you plan to use.) With wide troughs, thousands of yarns packed per square yard, stacked a dozen feet high in layers, you can pump vast amounts of water into the air. The cost of pumping sea water up onto those troughs, only a few dozen meters above sea-level, is less than 1 Megajoule per ton of water. A Megajoule generated on-site from solar, only pumping when the sun shines, costs about 1 or 2 cents, for a ton of water to evaporate and return as rain on farms and snowpack in the mountains. For anyone in Ag, this translates to “$12 per acre-foot of irrigation, with no pumping or well-drilling, maintenance, or ditches… because it just rains.” That sounds darn good to me! Compare that to the top-of-the-line desalination plants, spending 10 to 20 Megajoules per ton o
Ah, first: you DID claim that I "didn't provide specific, uncontroversial examples" and I HAD given such for why Bayes' Theorem is inadequate. Notice that you made your statement in this context:
<<"Bayes is persistently wrong" - about what, exactly?
Content like this should include specific, uncontroversial examples>>
In that context, where you precede "this" with my statement about Bayes, I naturally took "content like this" to be referring to my statement that "Bayes is persistently wrong." I hope you can see how easy it would be for me to conclude such a thing, considering "this" refers to... the prior statement?
You now move your goal-posts by insisting that my statement "Rationalists repeatedly rely upon sparse... (read 354 more words →)
