As it stands, we see a lot of people talking about how Western culture is superior, about how Israel needs to be defended even while it commits a genocide because it's a 'Western outpost'. We also see a rise in right wing governments across Western powers, and we're seeing them struggle as cheap resources are becoming hard to come by.
I truly fear that the ugly colonialism we saw in the past will return, and while they're committing horrifying violence they'll be claiming they're doing the global South a favor. They won't call it colonialism, but it'll be exactly that. Terminology rather than substance is what's more important; they'll be more concerned with what their actions will be called than what they're committing.
I want to point out that what we're seeing right now with Israel in regards to people trying to claim it's not a genocide, even if they do agree that all the horrors are real, is not something we haven't seen before in relatively recent history. In Iraq, when the oil for food program was instated, the human rights coordinator to Baghdad quit his job so he could criticize it as a genocide; his successor also quit saying this was indeed a genocide. The UN's response? To quibble about the term 'genocide'.
France has overthrown AT LEAST 22 African leaders since the 60's, and is most likely also behind the assassination of the Haitian president who was demanding reparations. They also, alongside America and NATO, overthrew Gaddafi, despite Libya being the most successful country in Africa.
How long before other European countries decide they want to go over to resource rich countries in the global South and 'liberate' them? I understand not every country can bring America's power to bear, but I wouldn't be surprised if they engage in joint ventures with America offering support.
All the horrors our government and Western accomplices have committed they've defended.
I genuinely hope the global South arms up heavily and prepares for this possibility, and I also honestly hope to see a successful pan Africa movement.
We're watching people literally say Israel's crimes are okay because Western culture is superior; if these people are, more than fine with genocide, ARMING a genocide, then these people will have zero compunctions with resuming the violent colonialism of the past. Colonialism didn't end because of the non-existent mercy of Western powers, it ended because it either wasn't feasible or because the colonizers were forced out. Life is getting harder in 'the garden' as Borrell called it, and since they see the rest of the world as a jungle, they'll have no problems 'taming' it for their resources. British people, even politicians like Farage, openly say they did nations like India a favor. They'll call the horrors they unleash a gift.
The rise of a right wing that idolizes 'the West', and despises everyone else is going to make this return of colonialism an easier undertaking.
Shades generally work anywhere but misters not so much. If you mist a plant in a dry climate itll work great, but in a humid one it wont do much. But the temps of the earth are universal everywhere. And in a humid climate when you run that humid air down thru the tubes and it gets cooler the waters gonna condense. Then your blowing cool dry air onto the plants and water particulates too. The sun hits it, evaporates the water droplets on the leaves, and heat is transfered from the plant back to the air. So the air doesnt need to stick around. Its leeching heat from the plant. Youd have to do it every few minutes. Frequency would depend on exact conditions locally.
The reason you cant just build a pond is that is a much bigger terraforming project and takes a lot of land, and water. Things most farms are already in short supply of. This method would utilize the moisture already in the air and the temperature already in the earth.
The things we need are already right there. Working out the specifics would just be an engineering problem.
The most energy intensive parts are the cooling of the air and the phase change of the water. The energy for that is provided by the sun, and the thermal mass of the earth acts as a condenser. With the fan doing the least intensive part of moving the air around.
Doing it every few minutes is why you'd need a larger underground pipe. With 1 m of 3"-diameter pipe per 10 m², you'd have 0.46 L of pipe volume per m². Even if it were to fully cool off once per cycle, it's still not a lot of breeze.
The breeze-from-beneath approach is unconventional and innovating but I think it would have a use case for purposes other than agricultural ones. I'm personally really eager to apply it to shelters.
