I think the bigger gotcha with carbon capture is it sustains the quid pro quo that climate change is the biggest threat to unchecked energy consumption growth. Behind climate change, there's also biodiversity collapse, ocean fish deple

That's not what I meant, and that you're thinking this kinda proves my point. People holding onto Bitcoin hoping to get rich don't contribute to Bitcoin as a technology. They're making Bitcoin a speculative asset. Bitcoi

As long as the vast majority of Bitcoin owners are HODLing and not using it, it's behaving as a Ponzi. Bitcoin has a few uses, but getting rich speculating on it isn't one.

BTC going up doesn't mean it has fundamental value. It's a speculative asset with more and more people getting on board. Hedge fund managers are rich. TV personalities are rich. Many PhD students are poor. This is not people makin

I've met folks who bought houses with fiat too. Moving millions across "money transfer unfriendly" borders sounds like money laundering to me.

That's so amazing to me. Most of the Bitcoin memes are about dudes who get rich selling half of their stash and buying a lambo with fiat. How is this gonna change human history more than dudes getting rich selling some stock?

Regardless of whether you agree with all the evil stuff, the fact is that Bitcoin is generating a lot of noise, speculation, and wasting a bunch of energy for practically nothing. I know practically no one around me who has ever used Bitcoi

So, only 1 order of magnitude down. EDIT: according to a chart here [0], 1 "raw" Bitcoin transaction is equivalent to 400k Visa transactions. That's 5 orders of magnitude. Unless Lightning handles 99.999% of all Bitcoin trans

An IC engine is 20-30% efficient depending on the technology (the rest is waste heat). An electric engine is 80-90%. Even if you imagine the electricity comes from a gasoline power plant, the efficiency at the plant will be higher than a re

Yes, the word for what you described is "misleading". Do not try to normalize it as it brings about confusion.

Carbon emissions from manufacturing plastic bags isn't really an issue either. The content of the bag will usually have a much higher carbon footprint (and if it doesn't, probably you wouldn't need a bag for it). If that is t

I think the EU was set to ban the use of palm oil for use in biofuels this year. Also, biofuel is/was "only" 50% of the EU's total palm oil consumption. And for other coutries, it's a lot less.

You cannot just use alchemy to create matter. Here they use sugar to synthesize palm oil. Then where does the sugar come from? How would it be sustainable to have massive sugarcane plantations instead of massive palm tree plantations?
