> '3,500 year rainwater harvesting techniques in India'

Although this would work in monsoon areas, it would not work in all parts of USA. There is law passed that rain water collection is "forbidden" (should be limited in some areas) as, as people collect water on the north, there is even less water on the South - increasing droughts and draining rivers.

In the beginning Elon's stocks especially SpaceX were worthless, if Elon was at the brink of collapse hardly that he could extract any additional value.

Honestly I do not understand Jeff, if I remember how Elon started, and how he had limited amount of his own money, and that he had only money for one more launch, and that there were issues with Tesla at the same time, so everything was about to collapse....

Jeff is nowhere near that situation, in comparison Jeff has "infinitely" more resources. He is richest man on the planet, he has almost 200 bn of wealth at his disposal, he can hire any team and build anything, he can innovate, and yet he behave like "patent" trolls do, so can someone explain me what is his problem?

I liked "Lateral Thinking"; it kind of opened a new space in my mind. Especially a lesson that solution always exists and that there are no bad ideas. As even the worst ideas can budge people to solve real problems, they could not see otherwise. Which subsequently taught me not to judge people when they say something that looks very dumb. I still remember his example of Boeing engineers asked, "what if airplanes had square wheels?"

I think question should be: to what extent things can be automated?

Is it possible to create a automated process that will with enough non-coding input create a workable software? In that regard answer is yes, same as developers are recording requirements, one day machine will have enough "knowledge/intelligence" to do the same.

Reminds me on this as well: https://www.nationalgeographic.com/history/article/150901-is...

Also I am not sure from newer history was it Khmer Rouge who order genocide of their own population over 40 years old, ideology was that they wanted to erase collective knowledge of elders.

"Pol Pot then began using intimidation efforts against the Chams that included the assassination of village elders but he ultimately ordered the full-scale mass killing of the Cham people."

I guess it is complex issue, especially as most of the goods we import from Chine so in the sense we have outsourced our CO2 to China, it would be excellent if they could switch 100% renewable, and recently I read news that they are close with Thorium reactors... so, I guess they working on it but as everywhere else progress is not as fast as we need it to be...

No, I am not assuming anything, I gave you the facts, so 4.7 bn trees was past year in Russia, Australia's 2019-2020 more than 10 million hectares of land burned, California 2020 4,397,809 acres (1,779,730 ha).

So, yes indigenous people used those techniques, to replenish forest but biologist say that 2019-2020 was not normal event. Especially considering number of animals burned was around 3 billion. https://www.bbc.co.uk/news/world-australia-53549936

So, of course they will stop burning when there is nothing to burn anymore, they will stop burning. Also our ability to plant new so far was not exemplary, and as I said, ability of sapling to sequester CO2 is very small. And each tree needs 15-20 years to grow to full size that can sequester more considerable amounts of CO2.

One more issue with trees worth mentioning is that past certain temperature, trees like humans, suffer a heat shock so they start dying. Which is again complication for growing new forest as saplings get exposed to higher temperature (not having collective cooling effect of fully grown forest) https://onlinelibrary.wiley.com/doi/10.1111/pce.12417

The five stages of grief: denial, anger, bargaining, depression and acceptance... so depression is not bad, many are still in denial phase. I look all those facts in a different way - not as a source of fear, but more in the way when you know facts that is it. I mean after acceptance, we can start thinking how can we improve things a bit, and maybe something good can come out of it.

I do not know, maybe like a cancer patient, they can choose not to know or to know, and then either do something about it or nothing about it. And only very narrow path can lead to recovery, but only, and only if they have a will to live.

Is there a marine biologist here? Would it help to genetically modify plankton so that multiply more and sequester more CO2 than usual? But again having some kill switch after x number of generations so it does not causes other issues?

If we had 0 babies for next 10 years population would reduce only 700 million which is again 7 bn or level Earth had in 2011. But further down the line that 10 year gap would create devastating knowledge transfer impact and also economic impact 20 - 50 years later.

I read the other day that in recent wildfire in Siberia, burned as much trees as it was planted in the entire world. And planted trees are young saplings they do not have ability to sequester same amount of CO2 like full grown trees.

I think it is this one: 'Russian fires burned 4.7 billion trees, seven times more than were planted' https://www.washingtonpost.com/world/2021/08/11/siberia-fire...

Just for the comparison 1 trillion trees project as of 30 May 2021, 164 restoration projects participate in the campaign and 13.96 billion trees have been planted worldwide.[7]

https://en.wikipedia.org/wiki/Trillion_Tree_Campaign

And if we take that idea was founded in 1977 that means 44 years ~320 million trees planted per year...

And that damage is only Siberia, what with Australia, Canada, California, Alaska, Amazon ...

Let say we succeed to stop methane leakage from cows (algae feed, etc.) and also leakage from coal, oil and gas extraction.

How are we going to stop Siberian permafrost melting (it has huge amounts of methane ice) it has potentially 100 to 1000Gt (currently 5Gt in atmosphere CH4) which is enough to tip the temperature to 2-3C?

Yes, I think your sentence is fallacy (I am not the one who gave you downvotes). And at the same time that is reason why UK is trying so hard to hide taking part in slavery and oppression during the imperialistic conquest. Genocide is a genocide regardless of the period of time. Some say that reparation cost to Jamaica because of the slavery would cost trillions, which of course UK does not, or will ever have any plans to do.

Also NATO waging wars around the globe was never legal or just, we were just going for oil and other resources using "shortcut". During NATO imperialistic conquest we have international laws and UN, but it seems that international organisation has more decorative purpose than anything else equally goes for Russia and China. Russia's war dogs would never be in Libya if we have not had destroyed that country first. During Roman empire at least they created roads, aqueducts, they gave writing system, what good did NATO give to any of those middle east countries?

It is Matthew 7:5 "Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother's eye."

I feel that each human nation as soon as they becomes a supper power they adopt behavior of a bully having bullies sense of justice e.g. "domination, violence and exploit".

Comparing a good technological achievement with moral and ethical values is not good analogy, but I understand what was your attempt. Speaking about the open space, i think that bully mindset is not really a behavior we want to carry with us. Do we really think that if other intelligent life (if it exist of course and is more intelligent) will let us?

Another issue is that space gives a military upper hand, meaning who ever deploys Moon base or Mars base will have ability to produce nukes or commence meteor strike on opponent country without much chance to defend themselves. So, in some sense something noble can be easily tuned to eval means. If China builds a moon base on the far side, we need to pair with moon base and spying satellites so we can track what are they doing, crating new military race, all the while mother planet is burning because of Global Warming as trillions are diverted - due to inability of nations to cooperate with each other.

Thus, I am trying to say, more technological power requires higher level of consciousness (goodness), otherwise we are just raging monkeys that will blow them selves up in one way or another.

I could envisage combat of a misinformation with misinformation or information... hm so... who ever first says you are a bot wins? :D

God forbid saying something anti-war or anti-oil you will be labeled as communist immediately

You literally made a list of all things wrong with NATO... and gave single war mongering point of propaganda view of Western mainstream media during 90'. Honestly I do not know how is this different than what Putin's media does in Russia or Lukashenko's media in Belorussia, so following the same thread of thought I can conclude you are the bot as well - just from the other side.

In that way we know that no one is not doing anything about it, and they are not trying to manipulate us. I say that is fair :)

No, that means first do your own, and then start bitching about others, because other way I do not see how are we better then those criminals in article.

Yes, I know, they are in our turf so now we need to bitch about them. What is the famous quote?, ah yes, "as we need to protect our economic interests" ...

As I said here: https://news.ycombinator.com/item?id=28140897

I feel articles like these are our personal propaganda. "Lets blame someone else, while our own war criminals roam free".

Tony Blair, Bush, Clinton ... they went into several wars without any approval of UN, made huge destruction, civilian deaths and suffering... and nothing, they live happily ever after ...

Thank you, is there any way we could find out what is probable life span, is it more durable (hailing/dust/corrosion) or less than silicon crystal? From time to time it would be nice if we had AMA on HN like on Reddit for the research team.

Also mA does not says much if we do not have voltage, and I am not sure what full sun means as in Africa full sun can mean 4.5 and 6.5kWh per m2 while in Europe we can get between 1 and 2.5kWh per m2 or radiation.

Thank you sir!

Honestly, I do not know how much technical my question can be, there is no tone, there is 14 words in total. I was googling and I could not find anything useful so I hoped I could get some answer from some technical person (material science/physic person). In my mind finding those number is the first thing I would do on the test bench, they give you prospect of technology some kind a range you would attract investors. You would have test sample 1X1cm you shine that amount of light and you get output. And then you know this is feasible and can help in future or not... simple as that. Instead I am getting some kind responses like I am talking with emotional teenagers tripping on some cry baby drugs... for heaven sake ... (yes that last is emotional response, I mean seriously what is going on with HN lately it used to be place with tech guys talking tech ...)

criticism, snark ?!

What are you talking about?! All I am trying to get some numbers, if anyone has them, but it seems amount of unhelpful comments begins to be overwhelming on HN.

What is:

Power output per m2?

Durability (life span)?

Production cost?

At least theoretical ...

In any order ... question is would you stay in company that measures engagement by the key stroke

If you were an employee of this company who left, would you resign and look for a new place or would you stay?

Great photos! What is the weather there during the year? While I was visiting New Zealand I found out that weather can quickly change, and kiwi told me it is usual thing they even have a song "4 seasons in one day"...

From the article first paragraph "with temperatures set to punch through the critical 1.5 degrees Celsius *threshold* by the early 2030s, a decade earlier than anticipated just three years ago."
