Christians, jews, hindu's, chicoms and nazi's also killed little kids without compassion. I am pretty sure that most of the worlds popular religions endorse the murder of children in one way or another.
We did become a superpower by international cooperation. Our international cooperation with the allied powers in the defeat of the axis powers in WW2. That and the fact that in the aftermath nearly 100% of our industrial capacity was still intact at the end of the war.
Gold is a terrible currency, the most overvalued material on earth. It has almost no real value. Its only practical use is as a corrosion resistant connector in basic electronics.
The currency that has had the most steady value in terms of a laborers wage over the last 4 thousand years is beer.
The elected leadership of Iran is a figurehead with no real power. and the last election was very clearly rigged the last time so that the Supreme Clerical Council would not have to invest effort in grooming a new pawn.
Efficiency of 90% for pumped hydro is irrelevant to its real cost as a complete ecological disaster. All forms of hydro power are terrible. This isn't even accounting for the evaporation losses that pumped storage will inevitably incur when used in the sunny arid environments where solar energy is most viable.
Efficiency of stored heat is based on its insulation, and can exceed 99%.
PV are at best a supplemental predictable daytime peak power source and in no way can effectively produce base load in the way that solar thermal can.
Considerations for cost: PV cells decay over time, for effective purposes solar thermal does not. PV cells only provide a cheaper alternative in the short term, and are only cheaper if they are not used to provide the power for the predictable daytime peak. Due to the storage issue, they can not provide baseline power for any reasonable cost.
In the long run, the only viable sources of clean baseline energy are nuclear and solar thermal.
Pumped hydro is not an optimal choice. The creation of surface reservoirs of all types are massive ecological disasters that result in the destruction of enormous amounts of land, and if placed in an existing drainage basin, disrupting the ecology of the entire river basin.
I am not unaware of the requirements involved in solar thermal. A gigawatt solar thermal plant will require about 125k-150k cubic meters of insulated storage for a 24 hour base load production. And because the you can control the amount of salt pumped out to produce electricity, and that will be its primary source of heat loss, you can get away with less volume if you expect lower nighttime electrical requirements.
How many millions or billions of cubic meters of water will you need to store to run a gigawatt plant for 24+ hours?
Right now, solar thermal is far less expensive than PV, especially when you consider the inefficiencies in converting electrical power to a store-able medium for use at night. The only possible way for PV to serve as a base load power source is if we have a global superconducting power distribution system or some fantastic almost magical revolution in energy storage. Neither of those options can exist yet, meanwhile solar thermal plants running 24/7 experimentally exist, and it is a simple matter of engineering and funding to get them actually built.
Natural Gas and Nuclear are not renewable. And nuclear power is "scary", despite being cleaner and safer than coal, oil and natural gas. And neither has anything to do with molten salt heat storage. If you are attempting to store electricity from ANY source of power, there is no good solution. However if you are attempting to store energy from the sun, as indicated by the original comment about "overnight storage", then you are far far better off storing solar heat directly than you are in converting it to electricity and then attempting to store it via electrolysis, chemical batteries, pumped storage or resistive heating of a molten salt reservoir (which no one was dumb enough to suggest).
You keep changing your argument against molten salt. First it is that it is too expensive compared to batteries, now you are saying it is not efficient enough with no baseline or comparison. The delta T of the salt does not matter, it is the delta T of the steam it produces that matters and >550C is plenty to provide high pressure steam for traditional turbines.
1) No large scale chemical battery arrays exist in reality. The largest array that I am aware of cost billions of dollars and can only provide emergency power to a small Alaskan town for 20 minutes. 2) The "hot" end of the molten salt storage cycle is over 550C, the cold end at 200-300C is just to keep it from freezing. 3) expensive? perhaps, but it is vastly, vastly cheaper than chemical batteries per watt.
My phone (Samsung Epic 4g) has a 5 inch wide physical keyboard with 49 keys (53 if you count the android keys). It would be just fine to program in a character heavy language like basic, though a brace/bracket/peren heavy language will require a lot of function key twiddling.
Elk don't live around where I am, but as a deer species they will have musk glands. And if those glands are not cut out ASAP, then the meat will taste a lot more gamey than it would otherwise be.
That doesn't change the fact that there's something wrong with a person who enjoys killing other living things. Of course, it's necessary, but the enjoyment of the task indicates some serious mental problems.
But then, everyone would have those cell phone clips on their belt so they can soak up sun instead of keeping it in their pocket. How will we be able to tell the douche bags who already have those cell phone clips from normal people?
Stored heat in an insulated molten salt reservoir is far more efficient than chemical batteries for overnight base load production. But you are right about hydrogen, A heat engine is a heat engine. It would not take that much extra equipment to pipe heat from burning hydrogen though the same boiler system for longer term stored energy.
At one point, I was in the top 50 or so Tac Ops players in the world. Anything over 50ms and the aim bot users always win. Between 30 and 50 I could compete effectively against the aim bot users. I don't know if I would consistently surpass the aim bot users at under 30ms as I never had the opportunity to test that theory.
I am not particularly informed on that case. But I would not say the entire US army is an enemy of the USA. But rather it would be those in the chain of command that made the decision to hide that information if it exists. That includes the joint chiefs and president if the decision went that far up.

Even with centralized power supplies, you can still use built in redundancy in the rare case that one fails.
