It is hard to tell if you are joking here or not, but in case you are not: if the cost of mining is low, the value of mining is also low. The reason for having 'mining' in Bitcoin is to artificially create scarcity in order to simulate blocks having real-world value.
If you can mine blocks for free, the value of each block plummets.
As long as Bitcoin is unusable for day to day transactions (7 TPS globally isn't even good enough to run a town on), it can't solve any real problems, because its value is just speculative make-believe. And no, Lightning or other L2 networks don't change that, since they don't actually use Bitcoin all that much - they don't actually give Bitcoin's assurances unless you run them at Bitcoin speeds (i.e. close the channel after every transaction, negating any performance advantage).
And if we ever automate every job away, littering could be the solution
There's a hundred other things we can dump energy on before deciding to waste it ; pumping water uphill, gravity batteries, regular batteries, electrolyzing hydrogen to use for later, ...
Why the heck would you use something so difficult/expensive to store & transport like Hydrogen?
If energy is expensive than it's makes more sense to store it in batteries than hydrogen since batteries are about 3X as efficient as the hydrogen cycle.
If energy is cheap it makes more sense to use about twice as much energy to capture and attach carbon molecules to that hydrogen to create a hydrocarbon resulting in something that's easy to store and transport, and that uses existing infrastructure.
You don't have to transport it very far if you generate it onsite straight in the hydrogen powerplant that'll turn it back into electricity with between 40 to 60% efficiency
If we follow your 3rd paragraph and turn the hydrogen into hydrocarbons, not only do you lose efficiency in that process, you make CO2 as a byproduct of combustion again
Nobody is interested in storage that turns your carbon-free green energy back into greenhousing energy
The reason you might want hydrogen instead of batteries is just cost, I guess.
> Nobody is interested in storage that turns your carbon-free green energy back into greenhousing energy
If you make your hydro-carbons with captured carbon, the process is slightly carbon-negative. ~10% of hydrocarbons are not burned, they're turned into plastic or lubricants etc. So for every 10 carbons you take from the air, only 9 are released back.
Bitcoins as grid energy storage? Just install my BitWall box next to the pv junction box. I'd be surprised if the economics math works out but that's a fun idea.
I cannot tell if this is sarcastic or not so the assumption is it isn't. In which case: WTF? There are many solutions for cheap energy but a pointless digest algorithm isn't one. While I do not agree with the AI craze it would still be a better solution.
When we are talking about search alternatives we are really talking about alternatives to bussiness model (otherwise why bother?), and Kagi is the only alternative out there in the sea of ad-supported search engines.
Of course Kagi is a real alternative. It's not Google search and you can verify that by trying searches and comparing the results you get from either engine.
It's interesting that they can narrow me down to less than 0.1% with just my language list (en-US,en,fr,ro). My user agent is practically unique as well, since I'm running an unusual configuration. I've never thought of that as a disadvantage when it comes to tracking, hah.
I observed this too, but I cannot really believe it. For me it finds just german on the iphone. I get 0.88% for it. But if all Apples do it the same, I can hardly believe this provides already such selectivity. The problem with such test sites seems to me that only nerds visit them, and therefore the database is small and biased.
I have "prefer English, German as fallback". That alone makes me almost unique as well. Not fully (like your special config :D), but enough that other resist fingerprinting options become meaningless.
They narrowed me down to an order of magnitude less based on just my browser user agent (latest Firefox Android). I'm not sure what that actually means.
I like this site for the info on how tracking is done it provides but the data set it generates uniqueness from is really tiny and differs a lot from real world browser makeup.
For instance it claims iOS is 4.63% of users and Safari is 3,42% when all other more complete statistical sources put those numbers at closer to 20%-30%.
"Ethereum 2.0 with Proof of Stake (PoS) could be launched in June this year. After the launch of Kiln, which is considered the last testnet before the final launch, there was speculation that the merger ... leading up to the final arrival of Ethereum 2.0, will arrive in mid-2022."
You can build not-so-complex user-cases faster and you can allow your non-tech team members to build and maintain internal tools (which eradicates the bottleneck between tech teams and business teams)
