Scientifically speaking, why not just do this?

Build colossal reinforced dams across the Andaman islands, Torres strait, Ryukyu and Okhotsk islands, etc

Because most of this area gets tons of rain, the water will naturally desalinate over time. Open channels at the bottoms of the dams would allow the saltiest, densest water to be pushed out into the ocean.

The Sundaland shallows would be completely replaced by freshwater rain within 30 years.

This water alone is enough to irrigate all the Eurasian deserts, minus Arabia. If it ran through an artificial river the size of the Mississippi, it would irrigate this area in under 200 years.

If you pipe the rest of the water into Arabia + Sahara, it would basically reverse global warming. It would also reclaim green, fertile land the size of THE AMERICAS. And it could probably all be done within 300 years.

>ring of fire
yes, this is one of the other problems I thought about. There are multiple avenues of easing this though

1) land-building, via dredging of sand from the sea floor. Admittedly this would be way more costly and extend the timeline of the project, but it is physically possible. In other words, this is no longer a dam, but rather artificial isthmuses

2) there are probably techniques/geometries that could be used to minimize damage

a Bohai land dam is actually extremely feasible this century.

Dubai (UAE) reclaimed 20 sqmi of land over a 15 year period.
A Bohai dam would be 170 sqmi

The Bohai land dam would be 9x bigger than all of UAE's artificial islands combined
China's economy is 30x bigger than UAE's

So in theory, China should be able to complete this artificial land dam in only 5 years.
They'd need to build an artificial river, I don't know how long that would take.
But it would take 45 years for all the water in the sea to desalinate naturally. I can't imagine that building an artificial river with China's amount of manpower would take longer than 50 years.

So basically they'd reclaim a UK/Belarus worth of land in 50 years.

I wonder... perhaps intelligence, beyond a certain threshold, is an evolutionary negative selector?

That is, you only need to be smart enough to build simple mud huts and tools to help you survive and reproduce. Thinking about stuff only adds more stress to your life and uses additional calories - it's a maladaptation, like peacock feathers. So penis size being inversely proportional to intelligence is evolution's way of stopping us from getting too smart.

tl;dr basically a spergout by a guy who thinks slapping solar cells to everything will solve the energy crisis. Not once does he mention the lifespan of solar cells or the energy costs needed to produce them.
He is either completely retarded or extremely disingenuous, and is a prime example of why youtube has turned to shit over the past couple of years.
Also, it's this kind of blatant retardation that reminds me that California should be nuked as soon as possible. Discuss.

Lifespan of solar cells is about 25 years, at least here in Europe. Cost isn't too bad and cost is always going down. And Si is abundant.

So yes, panels will probably cover all south facing areas, especially Germany is going all out here. Much of Europe is now having high cost of electricity combined with cooler weather, and Russia is starting the gas delivery diplomacy helped by greenies that thing gas is bad, further making Europe dependent on Russian gas to survive the winter. This too is making solar panels attractive. There are obvious problems such as sort days in winter with less power when you need the most.
>>
>>13892448
The cost of solar panels have dropped so far that they are the cheapest part of installing solar. I can get solar panels for less than $0.20 per watt. The cost of paying someone to install them far exceeds this already, that price is about equal to the price for a decent grid tie inverter. Hell even the mounting hardware can exceed the panel cost. Large scale solar farms are paradoxically more expansive than small scale ones.

I have a question related to lasers, my brother bought a 3W(Very dangerous stuff, a class 4 laser) that works on a wavelength of 450nm(blue light) laser engraver and it has already been tested on another place but it's back at my home now. The device works now the only issue I managed to get was it lacking another fan.
My question comes here, you see, I have told him to do some extra work on it before using it, doing an enclosure on it, a stable and safe place on which to use it, the actual planned place right now is too idiotic to mention, back to the main point, just how unsafe am I with this thing home.

I won't be operaring it, so my danger of exposure comes from 4 factors

>BEING AROUND THE LASER ENGRAVER (3W/450nm) IN A NON EMERGENCY SETTING
If I stay in my room locked, and light has no way of getting in since I barricaded myself with tape, a towel that obscures an opening, the usual opening below the door, and putting a mattress against the door.
Am I safe from
>light?
>hypercharged photons?
>fumes?
Or could I get either eye damage or lung damage from it?
The other 3 factors will be detailed below

No laser directly at your eye, reflected off of a highly reflective surface = safe
Simple as, don't look into the beam and don't have mirrors close to it while operational. If you're so fucking paranoid, wear 450nm (your claim) blocking glasses all the time.

Why the fuck would you do that? Just ape an R curriculum that exists. Don't teach both python and R at the same time either. Like what the fuck.

If you had more time, I'd tell you to focus on the basics and then teach them how to use R shiny and R Markdown. R is pretty stupid simple without touching any of the various libraries out there, but markdown and shiny are 'impressive' to the newcomer since you can quickly write up reports with code integration and create very quick web apps.

So they inserted PRRA between S and R
NS - PRRA - R
to get RRAR which is the furin cleavage site.
But why did they need to insert P?
RRA would suffice, no?
Also how do we know that RRAR is the furin cleavage site? It's just 4 random amino acids. How did they determine their purpose? Also there is another cleavage done at S2' by TMPRSS2 that facilitates fusion. Why doesn't anyone talk about that one?
>>
>>13895251
>But why did they need to insert P?
Probably an artifact from transfection
>Also how do we know that RRAR is the furin cleavage site? It's just 4 random amino acids.
Because thats what defines the cleavage site lol
Also, i think they tried to model it to see if it was in a region that could be cleaved. Its been a year since, I looked into it so I won't comment more.
