Sure, because it's competing against coal and gas which pass their externalities of wrecking the planetary ecosystem at zero cost to everybody else and their descendants.
If coal and gas had to sequester their output as much as nuclear, nuclear would obviously be cheapest because it's much easier to capture a small amount of solid waste instead of immense amounts of gas.
I think the poster above clearly understood the problem domain, in that the most common uses for "sparse array" is a "sparse matrix" for numerical computations.
And moreover, as is the case, the problem domain of matrix computations is known to be deep and problem-dependent, with a wide variety of representations and solution categories.
| But by all means, go ahead and implement your own formats for each of the various types of sparse matrices you are likely to encounter. Then optimize operations for each. Then implement complex algebra (eigenvalues, svd, QR, the works). In the end, hope that your brand spanking new wheel has no corners and works for enough use cases to justify not employing a standardized wheel. A smarter person than me said something along the lines of premature optimization and evils, but I suppose it does not apply to your brand of genius.
I see an unjustified insult against the previous poster.
The various cases and solvers have already been implemented in many important software packages for different domains, and given the centrality of matrix operations in high performance computing, this is not a premature optimization but rather the essential, core implementation and algorithmic optimization flowing from the proper mathematical treatment of the problem.
And his point was not at all to re-do everything yourself, but to be aware that there are in fact many varieties of sparse matrices in various settings and that this is not just a software-abstraction problem but a key mathematical problem, and there is no simple over-arching software abstraction that works well universally. The post described well-established problem domains with high-quality solutions.
Simply being aware of this not-always obvious fact is an example of scientific maturity.
Where does cost of lithium end up $300 / lb, i.e. ~ $660 / kg ?
I'm seeing prices of bulk lithium carbonate at $6000 per metric ton, i.e. about $6 per kg.
Molecular weight of lithium carbonate is about 74, which has two lithiums in it at about 6.9 each, so total lithium is ~13.8 of the 74, so cost of elemental lithium ignoring reduction costs is ~ $32 per kg.
| It may be that the statute of limitation on the original crime has expired and these follow on crimes are what is still possible to prosecute.

That would be a state crime, not a federal crime. The state would have to prosecute him for that one unless there was some kidnapping/sex trafficking crime involved.
The problem with that is the supposed victim would have to testify, and then be open to charges of blackmail himself.

Centralized generators run more efficient thermodynamic cycles than internal combustion engines which need to emit a widely varying power output over short time periods.
Centralized generators often run on hydroelectric and natural gas, which produce less emissions than coal or petroleum, and a few are solar, nuclear and wind-powered which have no emissions.
The end-to-end comparisons have been done with quantitative accuracy and show advantages to electric vehicles in many situations. You are hardly the first person to think of this consideration.
The Argentinian government, being a master of sense and competency, pre-emptively taxes white-market transactions on the normal banking system. They have power to enforce this on the credit card acquirers & merchant processors, and do it especially with foreign currency transactions.
Presumably there is some way to get 'refunded' some of the taxes back if you can prove to some idiot's satisfaction that you earned the money in a 'legal way' whatever that may mean.
So, doing it with bitcoin is basically a payment processor operating illegally and not collecting withholded taxes. It doesn't have much to do with bitcoin and everything about evading regulation.

| 2) The data for anthropogenic warming is weak. TRUE
This one. It's a deliberate lie.
There has been a very large increase in greenhouse gases in the industrial period. It is from fossil fuel mining and burning. This has caused changes infrared emissivity in the atmosphere---this is a measured fact, that the atmosphere is shining more in infrared. It is physically impossible for the climate not to warm.
Extensive data, geological and biological, show this is what has happened.
All other plausible non-anthropogenic mechanisms have been investigated and do not explain the observed data. Every aspect has been investigated every which way for decades.
| 3) Those who disagree with it are ex-communicated from the scientific community. TRUE
At some point, which is about now, they don't have good arguments or data. When they try, their arguments are quickly refuted. It now appears that they are willfully incompetent and motivated by achieving a non-result instead of actual scientific inquiry.
Particle physicists who disagree with conservation of relativistic momentum are similarly "ex-communicated" as they have nothing productive to add.
Exactly! And just as predicted by those pesky laws of physics, the climate was, until modern period, slowly cooling from about 6000 BC to now as the Milankovitch cycle of orbital forcing proceeds on its predicted path. It takes a Milankovitch peak to get out of the Ice Age.
Until humans started releasing greenhouse gases in mass, and that is now causing much more rapid warming.
| In the whole recorded history of the planet, CO2 *follows* the heat patterns
Except for the very important exception of now, when humans have dug up fossil fuels and burnt them in a mechanism never previously active in geological history. We have CO2 first, and now the heat's coming.
If something different is happening now, the results may be different.
The causal mechanism from CO2 to temperature is not derived from historical correlations but direct quantitative observation and physical experiments. The importance of the paleoclimate is that there may be natural feedforwards in which extra heat releases additional CO2 which would increase heat more still.

Indeed. Bohr argued, even earlier, with Einstein on this issue, saying that stimulated emission was impossible. Einstein derived the rate equations for the laser.
People erroneously imagine that Einstein was wrong about quantum mechanics. He wasn't. And in two central areas, the Copenhagen interpretation (it is a useful approximation but makes no sense as physics, decoherence does), and the laser, Bohr was wrong and Einstein was right.
