Could this be used in California as an additional fire extinguishing method?

Home to some of the best and brightest engineers in the world and California is still figuring how many firemen, goats and firetrucks to send.

Where are Google, Facebook, Apple, SpaceX, California state gov?

And Musk is still focused on LA traffic jams. I guess the worst fires in California state history are not enough to sway the titans of industry into action.

Even though these fires are happening in their back yard.

there are a dozen efforts and a lot of money (captured mainly), and yes, a lot of high-tech in play right now. one link:

But look how cool they can travel to space now!

I'm curious how places out there by the sea like Dubai are essentially a desert. Evaporation should be massive at those areas no?

Vegetation evaporates more water, faster, than the Sun shining on open water body surfaces.

I've seen a picture from directly overhead of the Amazon river where you can see clouds forming directly over treetops on either side of the river, but not the tiniest wisp of cloud over the river itself.

Earlier quoted context omitted.

I have no idea why shade isn’t a primary design concern for every park. It is almost always left to “there’s a tiny tree over there that will produce shade in 25 years”. It is shocking.

it’s also not just the shade. for some reason plant cover is significantly cooler than just shade. i am not sure why

Evaporative cooling. Trees pump huge amounts of water from the ground into the air.

I think the concern is the maintenance. Trees lose leaves in autumn increasing labor costs. They may also fall or have large branches break off in storms causing damage. I think its lazy and anti-environmental but less expenses ftw.

No trees near water. Algae, maintenance.

Evaporative cooling for the win. I wish (any) parks had this built in (ignoring splash/water parks), because it would be easier justifying brining kids out in this type of heat (especially for parks with no shade due to poor design). It would also bring more community together to have outdoor areas that are dramatically cooler than the surroundings.

It doesn't work well most places west of the Mississippi (where evap cooling is most effective) because all the water is owned at least twice over.
