"desert" comes in all shapes and sizes. The Tibetan plateau is huge, a high altitude arid zone. it encompasses deserts, steppes, it's distinct from the Gobi and it's not death valley, or the sahara. I had to rid myself of barchan dunes marching into the distance and the camels are two humped, and shaggy like ponies.
Indeed. I think the dry valleys in Antarctica are one of the driest deserts on earth - not necessarily where you'd expect to find a desert at all, but an absolutely fascinating place with all those dessicated/mummified seals.
Fun connection—"3 Idiots" is a Bollywood film about the journey of three engineering students at an Indian college, inspired by Wangchuk's (the engineer's) life!
In terms of cost it seems way way cheaper. The water is stored near where it is needed (so no canals to dig), and you can throw up another one for $125K vs the millions of $ to build a dam.
So I'm guessing the evaporation challenge isn't a deciding factor here.
That said, I wonder how much longer you could keep the ice if you had reflective blankets to cover them once you've "grown" them as much as you can (enter the dry season).
Color only hints to heat reflective properties. Most of the heat of the sun is not carried in by the visible spectrum. And concerning snow, it is not particularly good at reflecting IR (1).
More a conceptual objection to using blankets. Feels like overengineering. The Ice Stupa idea of Sonam Wangchuk is brilliant IMO and if this minimalist approach would work would be fantastic.
I'm having trouble remembering the name (it's obtuse and my searching is bringing up different, similar phenomena - cryo-something iirc), but once the warm dust starts to dig a little hole with some fresh water in it, biofilms of algae and fungi begin to form at the bottom. They're dark colored and accelerate the process further (increasing the size of their habitat).
At least, that happens with real glaciers. It may take a while for a similar phenomenon to arise on artificial glaciers. But sure as sunshine, if there's sunlight and fresh water, the algae will figure out a way to exploit it.
I always wonder that about seemingly-spontaneaous fungus and algea appearance: where do these organisms come from? Are they somehow airborn, or rainborn?
Interesting, I hadn't heard that before, but it's certainly related. The word I was searching for was the term for this particular biofilm/community, so it's some long technical term.
It's a lot easier to remove dust from a dry surface (the wind may do it for you - I recently listened to an interview about Mars rovers[1], and they mentioned most of the dust that gets on their cameras gradually blows away).
I imagine a shiny reflective blanket will reflect more infrared than just snow, and also trap coldness in the air between it and the snow, acting as insulation.
One of the first impressive creator blogs on the internet, I guess ~2001, was someone, somewhere (Canada or Alaska?) making one of these. It was massive, bigger than these from memory.
I don't think the blog was archived.
I assume this is a 'thing' in colder rural communities in North America. Their version of pallet stacking.
Now make it pillar shaped, on an onion pressure seal pressing down on a reservoir of its own making. Water, a little energy and coolant store all ar once.
