Thanks for reminding us that there is no way to generate electricity other than by burning fossil fuels. This is a simple, True Fact that nobody ever seems to remember.
HFT increases the liquidity of the stock, and therefore its value (slightly).
The way I understand it, this isn't and can't possibly be true.
HFT "works" by creating both buy and sell orders for stocks and commodities at the same time, and either completing those transactions or canceling the buy/sell orders and posting new ones based on new information, often several times per second.
If the HFT system ever completes a buy/sell order, it only holds the stocks it trades for typically less than a second, meaning there must be a matched bid to buy and a request to sell that stock within that time frame if any transaction is to take place. Otherwise, the orders would be canceled and reposted.
In other words, HFT can only be effective if there are already buyers and sellers in the market at that specific time, and even then only to the volume of stock that is being sold or purchased.
I have a hard time seeing it as anything other than a man-in-the-middle attack looking to shave a few fractions of a cent per transaction. Maybe this made sense before computerized transactions were a common thing and you still had humans negotiating the transactions, but now that *all* transactions are negotiated and matched by computers it seems completely unnecessary. =Smidge=
Subsidies do not reduce prices; the costs are still there, you're just paying for it in your taxes instead of at the pump/meter. The stick in the eye is, with subsidies you're paying for it whether you use it or not.
That said, the benefit of subsidies is as you say; to foster growth by hiding the true costs and making the sticker price more appealing, and that is not inherently a bad thing. =Smidge=

Converting carbon dioxide back into carbon is a lot harder than moving mass to a higher elevation, solid or liquid, and a hell of a lot less efficient.
I'm actually asking that the current tyrant in the White House get replaced with someone that understands the role the federal government should play in our lives.
Which, of course, is exactly why the Obama administration has expanded the scope of federal loan guarantees towards nuclear power construction projects... because he's anti-Nuclear.
It's not the government that's preventing nuclear construction. Private developers (aka "The free market") don't want to spend the billions of dollars necessary to build them. They can barely be assed to spend the money to maintain the ones they have!
There is a grand total of SIX power plants currently seeking regulatory approval. You might have a point about government being a bottleneck if there were dozens of them, but nobody seems too keen on building multi-billion-dollar nuclear plants with gas and oil (and now, renewables) flooding the market with much cheaper energy. =Smidge=
Yeah, and during that blackout, Indian Point was out for a full week.
The point is, "How are you planning on replacing the power loss?" is not a valid concern when they already replace the power lost when the plant goes offline on an alarmingly frequent basis. =Smidge=
Renewable energy gets less than half as much subsidy as petroleum, and it becomes less than 1/5th of what petroleum gets if you exclude subsidies for ethanol.
I'd be happy if they simply made it equal. =Smidge=
The same way they replaced the power loss when the either or both of the plant's reactors are unexpectedly taken offline due to equipment failure, fires, accidents etc. There have been dozens of incidents that have knocked the plant offline without little or no warning and I doubt anyone not paying close attention has ever noticed. The plant is plagued with incidents from control rod failures to transformer explosions to errant bird shit. Somehow NYC has been spared from crippling brownouts.
As it turns out, the grid is remarkably resilient! So even if you were to replace the now 40-year-old reactors with something "less reliable" like wind and/or hydro (if only there was a large body of flowing water nearby...) there would demonstrably be no deficiency in power.
All that is on top of the numerous close-calls and safety violations the plant has been written up for over the past two decades. The place is almost literally held together with duct tape and bailing wire, because maintaining it is expensive and that's bad for the shareholders. The latest tritiated water leak (which is by no means the first, or worst) is just possibly the straw that breaks the regulator's back. =Smidge=

South Dakota is the fifth least populated state in the country, with roughly 860K people. It would be relatively low financial burden for retailers of any size to refuse services and sales billable to SD addresses.

My thoughts immediately jumped to RFC1459 - Good ol' Internet Relay Chat. There's been plenty of instant messenger applications over the years.
I don't quite see the advantage of "real time" though - watching someone type is boring, and they (or at least I) often go back and edit to fix typos or choose a different wording. One of the advantages to text is you can do that before committing. =Smidge=
There is absolutely no reason to consider the battery requirements for running the entire country, and it's kind of asinine to just average it out like you did.
Solar can handle a significant portion of the peak loads, since the peak loads coincides strongly with time of day. Wind, hydro and whatever other whatever region-appropriate renewable can fill in for most of the night/off peak loads. You'd only need storage to cover the edge cases, and not all of that storage would need to be chemical battery (see: pumped hydro, compress gas, hydrogen, thermal, etc)
Chemical battery has the advantage of being easily deployable in small amounts, perfect for private homes and small businesses. =Smidge=
The pressure really isn't that big of a deal. 2000PSIG sounds high, but industrially speaking that's not terribly impressive. To put it into perspective, CO2 storage cylinders are often 1800 PSIG.
Compressed natural gas as a vehicle fuel is 4000PSIG Max. Compressed hydrogen storage is 5000-10000PSIG.
More importantly, it's not the max pressure that's the important metric but the differential pressure. You wouldn't be compressing it from atmospheric pressure - the MINIMUM pressure in the system is going to be somewhere around 400PSIG.
Of course, this prompts an important question: Where the hell did "2000 PSI" come from? Existing commercial trans-critical CO2 refrigeration operates at ~1300PSIG, so either the designers of this system have determined there's a good reason to go all the way up to 2000 or there's some journalist math/sensationalism going on here... 2000 PSIG is typically the relief valve setting, so maybe that's the confusion. =Smidge=

All electric vehicles currently for sale have a range of at least 100 miles. This means The vast, VAST majority of EV trips will not need to charge at both ends of their journey. In other words, not every parking space will need a charger. =Smidge=
The immediate and obvious problem with your calculation is the input number: "11,000 cars a day"
Interstate 40 serves not only through-state traffic, but also local traffic which may or may not cross state lines. So what you need to demonstrate is that 11,000 cars per day travel straight through the state, all 330 miles, without any local stops, thus requiring dedicated charging areas to handle that traffic as opposed to destination charging.
If you're just using a bulk average, then the vast majority of that traffic will be inter-county and local - a considerably shorter distance per trip and trips that are likely to use destination charging. Hell, I often use an "Interstate" to travel as little at five to ten miles simply because there aren't any traffic lights... =Smidge=

I'm saying your math is very suspicious. You asked for better thoughts, so I'm providing some.
If pretty much every car is an EV then pretty much every parking space will have a charger to keep the batteries topped up.

95% of trips taken by car in the US are 40 miles or less.
