Almost all of those videos are real. You can in fact quite easily identify most areas down to a few 100s of km just from the surrounding nature. It takes some practice but it is for example very easy to learn which continent the nature is in. The videos you see on social media is also of course the best case out of 100s of games.


After hyperloop and tesla semi, I don't trust Elon that much.


The carbon removal plant in the picture is from climeworks where you can subscribe to carbon removal, if anyone is interested. Cost about $1000 per tonne https://climeworks.com/roadmap/orca


Thanks for posting this, I just subscribed. They should include a way to invite others to check it out, send personalized invites to the emails I enter.


That's one part - they have a wide range of removal methods and you can see their applications on Github: https://github.com/stripe/carbon-removal-source-materials


It also also means sleep 24/7 in for example northern sweden during the winter


I used Google calendar to send free SMS to myself with information about my services running on my raspberry pi. Each service had a future calendar entry with SMS reminder. Under normal operation the service would move the entry forward in time. If it had crashed, I got a SMS.


Sweden is actually the first country to build such an plant. Att the moment it is mostly testing plants but the real ones will be built soon. https://www.hybritdevelopment.com/


In Austria as well. https://www.voestalpine.com/group/en/media/press-releases/20...

EDIT: I should have read the article first.


In the 1950's Norway had a pilot plant that made iron by electrowinning sulfide iron ore. Which was a waste product from copper mining. Used a low temperature wet cell. And the steel industry was perfectly happy to take their small production runs.

From memory efficiency was 4.5kwh/kg. At 12 cents/kwh that's $0.50/kg.

Seems like a better idea to do that than to pretend hydrogen is 'green'.


The amount of hydrogen you need for hydrogen DRI is quite small. From this source: https://www.energy.gov/sites/prod/files/2018/08/f54/fcto-h2-...

You need about 54kg of hydrogen per ton of iron. Assuming it takes 50 kWh of energy to make 1 kg of hydrogen, you get something like 2.7 kWh per kg of iron. This is significantly more energy efficient than the idea you're proposing.


Found this report from a more recent attempt.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6918249/

The Norwegian pilot plant used a crude asbestos separator for the anode and cathode. The above used some magic polymer.

They got it down to 3.53 kwh/kg


The same is true for solar that is not easily recyclable.


What part of solar is not easily recyclable? The glass? Oh noez, now the world is being polluted with silicates!


how would solar result in areas beeing uninhabitable for decades (or much longer?) after we stopped using them?


Please rename the link to "The Economics of Maps (PDF)"


Maybe the last part should also be included? The last reply is "yes, but I will write a pm about it". This is the answer to the statement about there being two interigations if she creates a new one.

Maybe we can request that PM?


I think in this context PM is short for promemoria which means "memo", as in, "yes but I'll write a[n explanatory] memo about it"


You can always follow USA where minimum wage is not enough to live :) - the wonders of the right.


I would suggest following the Scandinavian model of not having a minimum wage at all.


Which works because of strong position of unions. The minimum wage issue can't be simplified to "no minimum wage and yet they thrive"


The USA minimum wage is definitely enough to live on, and comfortably. (Just not in the USA)


Lots of minimum wage remote work in the US?
