Thing is, it is possible to make it profitable. Trees fixating carbon produce wood. Cut trees, sell wood. New wood grows. Repeat. The more wood we use in construction, furniture, paper, the more carbon is removed from the atmosphere.

Hopefully we will get to the time where atmospheric carbon scrubbing will be acceptable to discuss.

I think the first place that will switch seriously to solar will attract a lot of energy-heavy industries that can have intermittent production but I suspect it will just be a bonus for the first country to do it.

To me that mostly means free or cheaper than zero electricity during peak time. That’s going to cause a total shift of mentalities as many “too inefficient” things will become a possibility.

Good to know, thanks!

Ah that must be it sorry. I thought they had decorelated phone numbers and IDs

Groups have an encryption key that I guess you receive from other members upon joining.

Spaces is an underused feature that I hope see gain more traction! It makes Matrix a credible competitor to Slack and Discord

Not really, have used it for years like that. But you need to set it up initially on your phone. The newish feature (less than a year) is that I think they do not require a phone number to set up a new account.

That’s really interesting! It shows which communities share users. I am part of jlai.lu, a french-speaking community that is relatively isolated by also slrpnk.net that seems very spread out!

Would it make sense to compute the standard deviation of each instance’s communities? It would give an idea of which are islands and which are more extended. Not sure if it makes sense to compute it more on 2 dimensions or on the original 21934 though.

Sorry I don’t have it handy, just read it, probably on /r/askscience a while ago. A quick search indicate that maybe this is not as true as I thought. That seems to be the case mostly for coal and for some forms of oil, but not all of it.

Not really IIRC. Modern bacteria are more efficient at breaking down organic materials and forests buried today won’t make oil anymore.

It is renewable in the sense that given infinite time, you can use it to grow infinite energy (for the nitpickers: assuming an eternal sun).

It is not infinite though and the amount of power you can extract from it is limited but that’s true for every renewable sources: you have a limited amount of places where you can put dams, where you can put windmills or even solar panels.

What is important is that it is not power generation that consumes a scarce good (as fossil power does) but that it is increases in power generation that consumes it, in a reversible way.

At one point hopefully it gets banned.

ITER does not aim at being a power plant. Its heat is directed at cooling towers with no turbines. The first fusion power plant is supposed to be DEMO which is supposed to start producing electricity by 2050.

Does it mean that production reached the level where intermittence becomes problematic?

I know. But we know it is “just” an engineering problem which can be solved at a high cost.

Fusion is a field where you can’t have the “statup mindset”: investments are in hundreds of millions and take at best a decade (and most likely two) to pay off. That’s one field where it can’t go anywhere without public funding.

It is very possible that China gets there first, considering how ridiculous western fusion efforts have been.

I wish we thought about it before letting them join WTO.
