Why? Because all the overpopulated areas of the world depend heavily on technology for their existence, and will diminish said population when the electricity is turned off for a few years. When will that happen? When our undefended electric grid succumbs to a Carrington-event-scale solar tantrum. Word is that US population will drop by 90%. 30 million people aren't going to make shit go extinct. They may be eaten by the residual mountain lions and grizzly bears, tho...
I think America needs to have a gender equality tariff, as well as a child labor tariff, and other social engineering that we're doing here at home applied to the possibly advantageous business practices of our international competitors. Those companies found to be doing such discrimination would get the tariff. Tariff by company? Can we do that? Lets try it and see if it flies...
They were called the Krell. Had this big project, creation without instrumentality. Their own flaws consumed them overnight once they turned on their big machine.
...which the President is attempting to execute, and with the opposition of almost everyone in Washington.
The basic problem with Amazon is that it is NOT manufacturing, and NOT mining, and NOT agriculture. It is retailing. Manufacturing, mining, and agriculture produce new, tangible things for sale, rather than simply moving money around with some having a better shot at siphoning off more of it than others. Winners are executives and managers, losers are line employees.
The cure the President wants to make happen is to bring manufacturing back in a big way. Manufacturing pays far more than these retail jobs. If 100's of 1000's of factories can be opened or re-opened (we've lost more than that to overseas flight due to our income taxes chasing them out of the country), those Amazon workers and Walmart workers and burger flipper workers would all be showing up at manufacturing plants to actually build things. They would be paid more than what they're paid as retail employees.
What happens then is that people to work retail jobs begin becoming scarce. Amazon, Walmart, and the burger flipper employers start having problems getting help. They can't employ enough people to run their businesses. What do they do? Sure, they'll employ some robots, but robots can't clean the bathroom, interact well with customers when something weird goes wrong, and may or may not be able to successfully drive a forklift without running over people or damaging the merchandise. IOW, these places are always going to need help. So... they hire less, but they hire at higher wages.
Wages too high to qualify for food stamps.
And that's the cure for this. Get people working in high(er) paying jobs, factory jobs.
Both sides oppose this. Some don't want to change, some are making a fortune by building things offshore and importing them and are scared that they won't make as much by building in the US, some just want to "keep those people down" so that they can buy their votes with welfare money. But the President isn't any of those people that wants to screw the American worker. He's fairly unique in Washington. I've watched him from waaaay before he became President, and he's ALWAYS complained about these people that want to exploit workers. Now, he's decided to do something about it himself.
So, that's why the big corporate tax cut. Get the factories back. Should work, although passing the FairTax, which has NO corporate income taxes (or any other income taxes) would work better, but that is probably a bridge too far right now.
"The science is settled. Global temperatures are rising. Sea levels are rising. Severe weather is getting worse."
Yeah? So? Just what do you think you can do about it? We don't need to "reduce", we need to STOP. Can we? Not until we get the magic battery. If we get the magic battery (cheap and small and cheap and energy dense and cheap and lightweight and cheap and rugged enough for mobile use and... BTW... cheap), we'll be at least ABLE to reasonably think about stopping the burning of fossil fuels. Otherwise, carbon is energy. We need the energy. If we throttle back without regard to reality, we'll just plummet millions of people into poverty, and poverty kills. OTOH, once someone invents the magic battery, or magic supercapacitor, the conversion will happen at light speed. Why? Because electricity is, and is likely to remain blindingly cheap when compared to burning stuff for energy.
So, really, what we should do is stop fighting about "cutting back", but instead channel all that energy, angst, and money into inventing / discovering the magic battery or magic supercapcitor. We do that, and our cars once again run on the equivalent of $0.85 - $1.10 a gallon fuel. Big boost in prosperity, exactly what we need to stop adding CO2 to the atmosphere, become energy independent, quit having disasters involving burning / exploding fuels, etc.
Its not self-driving until I can get in the back seat and sleep while attaining my destination. Then get out, tell the car to go park itself somewhere, and summon it later when I'm done.
This nonsense of someone sitting in a driver's seat, breathlessly waiting to grab the wheel away from the errant computer is just a formula to 1) die in a horrible accident or 2) get your ass sued off because you are incapable of being that attentive with nothing concerning you is happening for hours and hours. Someone should probably do a study, but It think it is probably humanly impossible to perform that role. You're just someone to sue when things go wrong.
Either the car drives, or I drive, no half-assed partnership will be tolerated. I get to sit and play video games, or I make every decision and execute every direction correction myself. There's no in-between if you're trying to sell me a "self-driving" car.
Get the Sawfly sunglasses the troops use. Stand up to a 12 gauge shotgun at 13 feet. You won't put them down somewhere and lose them because they're over $100. There, problem solved...
Certain situations don't accommodate such action well.
I first got glasses that did this in the 70's. I was a 2-way radio tech at the time. I'd get into a trunk of some cop car where the radio was, it was fairly dark, and because the car was outside in the sun, my glasses were dark and I couldn't see squat about what I was doing. Got rid of such glasses at the next prescription change. Contacts might be a little harder to change out for clear ones than glasses.
I do, or did when I used to fly. Don't do that any more due to TSA nonsense, but I always thought I'd have my brains scraped off the ceiling due to turbulence someday if I didn't.
Both of my Win 10 problems are absolutely true, and I even forgot one. There was another one a few months ago with the laptop, a Surface Pro 4 that I bought last summer, that all of a sudden booted up with a completely black screen. Since I bought it at Best Buy last summer and also bought a 2 year "extended warranty", I just took it to Geek Squad and let them wrestle with it. They had it fixed in a few hours, so I picked it up that night. But the tech said that yes, another update went south, and caused it. Yep, Win 10 is unreliable.
Meanwhile, the update that I got about 10 days ago broke the ability of this computer to do the "no password required" bootup. It would give an error message and tell me unless I logged out and then logged in myself, my creations wouldn't be accessible in the future. Or something like that. Ran a few diagnostics / fixes such as scannow and it passed fine. So now, rather than run around and try to find the cause, I'm just waiting for the next update to fix it. The laptop is working fine, no problems with no-password bootup. Its just that a month ago, while on a cross-country trek from Virginia to Arizona, something happened (probably another update) and the keyboard and touchpad stopped working. Then, 2 days later, it magically began working again. (Probably another update.) Win 10 computers are getting to be really unreliable because of the updates dicking with them all the time.
And I'm not hiding from them either. Just not gonna get all worried about it. There's certain things that concern me, most of 'em emanate from DC, but this ain't one of 'em.
Only partly. Vinyl is truly high fidelity. Various notable musicians have expressed that they believe that CD's "lose something" that is captured better on vinyl. Have seen these from time to time from some big rockers, don't remember who.
I was surprised when I fired up my 50 year old turntable and put on a record after having not done so for a long time. The sound was only less quality due to the clicks and pops which, since I've always taken care of my records, were few. I've always used a tracking force of 0.5 - 1 gram, and that doesn't damage records very much.
Haven't had privacy since I got my first phone in my name. Everybody knew where I lived and how to contact me. So what? I actually want friends to be able to find me. For non-friends I have a Mossburg Maxi-Combo 500 in 12 gauge, so all's good. No worries.
No, I think it's more like devising a method of limiting things to 15 amps. There's some calculation to do but that I sense some stuff doesn't make sense at this level. Can 15 amps really fill up a large supercapacitor. Amps is the flow of electrons. A capacitor is a storage vessel for charge, which is a certain number of electrons. If a much lower voltage will generate the 15 amps, then we only need that voltage.
The challenge is to limit the current by limiting the voltage differential between the source, which is the powerwall batteries, and the supercapacitor. This would then be accomplished by limiting the DIFFERENCE in the voltages of the batteries and the SC. If the batteries have 0.3 ohms, then the voltage difference would need to be 5 volts to yield 15 amps of flow.
Increasing the battery voltages continuously, as the voltage steadily increases across the SC, and keeping the difference at 5 volts, would limit the heat in the batteries to I squared R, or 25 X 0.3 = 7.5 watts. How to make variable voltage battery?
Individual lithium cells are 3.7 volts if I remember right. 2 of those would be 7.4, so 22.6 amps would result across 0.3 ohms internal resistance, and simply adding cells, switching them in as the capacitor voltage rises might be the way.
Yep, the math all works that way. But still, there has to be a way to charge capacitors that measure their capacity in multiple farads.
Breaking the supercapacitor up into many small ones, and charging them in succession so that you're charging a 0.1 farad capacitor at 50Kv would cause it to "fill" quickly, so the spike in current flow would be short, then move on to the next one, etc. Charge in 10 minutes? Dunno. Thomas Edison would probably make short work of this problem. I toured several of his labs and muesums last year, and the man was amazing.
We might not be able to apply 50 Kv from the start, eh? Either the source batteries blow up, or the supercapacitor blows up. (There has to be a way to do this, but it doesn't readily come to mind.)
The energy density of the supposed "breakthrough" supercapcitor isn't stated, so I'm going to assume a team that is working on it for automotive use are not so boneheaded as to purse something for automotive use that is so large as to make it prohibitive for automotive use.
As for charging at 50Kv, I wasn't clear. I meant that the vehicle supercapacitors AND powerwall batteries would BOTH be connected in series temporarily to bring the voltage up to 50Kv, and then the batteries should have no problem flowing enough amperage to charge the vehicle supercapacitor in a short time. The cables would have to be insulated up the wazoo for safety, but amperage - 500 miles at 4 miles per KwH would be 125 KwH or a need to put 750 Kw down the wire for 10 minutes. At 50 Kv, that would be 15 amps. Sounds doable.
The quoted article says 180 watt-hrs/Kg for the supercapacitor, as opposed to 100 -120 Wh/Kg for lithium, so its not a capacity problem.
As for melting wires, yeah, that's something else to solve. Use 1000 batteries and wire them in series temporarily during the charge, so you connect up to 50,000 volts with smaller amps? Have to be real careful with that, of course. Or maybe just use huge charging cables... probably need a hydraulic arm to life and connect them!
12.5 cents per KwH here in Virginia as far as I know. Charge any time I want to. Get out of California and other such states that allow pricing on a time of day basis and improve your life.
