Thirdly, we haven't even proved that a single photon is a wave. We have shown that a stream of light particles acts as a wave, through the double slit experiment, but not an individual photon.

The double slit experiment works fine with one photon at a time. If you do not measure which path the photon takes, then each photon takes both paths and interferes with itself.

Actually tech workers should get paid as much as lawyers. Stop giving away the jobs to shit indian and we can get some money for all.

You are licensed by The State to practice law (this was not always the case) which conveniently limits competition and prevents outsourcing. Of course these same lawyers passed these laws for our (their) own good and have every incentive to make law as simple (complex) as possible.

Comment: Re:Time to switch to DC? (Score 1) 53

With DC, you can put solar power directly into the distribution grid without conversion inefficiencies and phase synchronization issues.

You still have the same system wide frequency compensation and phase margin (not related to AC phase) problems which overshadow AC phase matching.

Not only is solid state DC voltage conversion more power efficient than passive transformers, you do not run into nasty polarity and phase issues, which can be huge infrastructure liabilities.

DC is only more efficient when long distance high voltage transmission lines are used. DC allows a higher voltage to be used without excessive current and radiative losses. The transmission line itself takes a lot less metal for the conductors.

For distribution AC has the advantages of better arc interruption, easy passive impedance matching via transformers, and easy passive isolated current sensing. Ever notice how a given switch, circuit breaker, or fuse has a much lower DC than AC voltage rating? This has implications for high voltage DC connectors as well.

While high efficiency motors can make better use of DC, that excludes all other AC motors which are too small to make that economical and motors are pretty efficient already so there is not much to be gained there.

Sure, you can demand a trial, but if you do, we're going to throw every possible charge at you in a grossly disproportionate manner, in a trial you're probably not likely to win, especially if you're poor.

One reason they stacked charges is that at least previously (I am not sure when of if this changed), sentencing was often based on charges instead of convictions.

If you want to get rid of plea bargaining you're better off getting rid of the vast majority of vice crimes.

Or force all trials, even down to "civil citations", to go to a jury which determines the facts and make the state pay instead of allowing it to use "fees" extracted from the defendant. As it is, defendants pay the state so the state can try them. This would allow the real cost of the legal system to be measured and soon enough the state would decide to concentrate on the crimes which really matter.

Also treat civil forfeiture as the crime that it is.

who faced up to 35 years in prison for an act of civil disobedience... he was offered a 6 month sentence if he would plead guilty. 35 years was the "street value" of his sentence.

I have watched this process in court and there is nothing to bind the judge to any agreement with the prosecutor which the prosecutor can change at any time anyway. It is very much like a contract of adhesion where it is take it or leave it and they can alter the deal after it is made.

U-Verse did a great job flipping that switch where I am. IPv6 is both enabled and disabled on their router but they also now block protocol 41 (and they did so before enabling their broken IPv6) so my existing IPv6 tunnels which ran for years without problems are now useless. I managed to find a customer service transcript where AT&T says that they deliberately block third party IPv6 because of security and because otherwise their users would be able to get static IP addresses without paying for them.

You worry about handling load variations but you have a bunch of battery systems with grid tie inverters. Tell them when to turn on and pump power back to the grid (or at least reduce load), if there is a load spike. Problem maybe not quite solved, but certainly reduced.

This is a pretty uncommon configuration because of the expense. If you have a grid to tie to, then you do not need the batteries. For those that do have batteries, they would need to be paid by the utility for battery wear. Because of scale, it would be more economical for the utility to maintain their own balancing infrastructure.

Thanslation: "we're too stupid to do our jobs properly". Well, kids -- those are control systems. Engineering is pretty smart these days. Do your fucking homework: you're getting paid for that.

To be fair, it is not an easy problem economically. The impedance of the distribution grid is not zero so returning enough power at the endpoints of the distribution grid will cause the voltage to rise out of tolerance at other points. Correcting this requires either more wire to lower the impedance or active voltage regulation in the form of changing the transformer taps in real time. Both involve infrastructure upgrades which would not otherwise be necessary. Who is going to pay for that? If it is only the customers who are returning power to the grid, then batteries are going to look economical.

It is a political problem and not an engineering problem.

Going off the grid is silly. The reason we have a grid in the first place is because it's much more efficient (specifically COST efficient) to have centralized production of power that doesn't easily cut off when something goes wrong.

The largest initial and ongoing costs are for the batteries; if they were cheap enough, it would be cost effective to go off of the grid. I doubt this will happen but I would not rule out politics making grid power expensive enough to make existing batteries cost effective.

If you want to go off grid on your own, go for it.

Conveniently this is unlawful in most places. You are required by law to have a grid connection.

I suspect that experiment won't last very long once you discover just how difficult it is to actually maintain a stable 120/220/230V 60/50HZ AC 24/7 that stays in phase. Most people really don't want to go back to third world style "power doesn't actually work 24/7 and you keep getting outages when something fails", and most of our home appliances are simply no longer designed for that sort of power input. They expect 24/7 reliable power.

This is the simple part. The only thing which will damage a well designed inverter system is lightning; they are very fault tolerant in other respects and I think you are overestimating the difficulty in producing reliable self generated AC power. The largest problem is simply running out of it because of inadequate battery storage.

The politics are insurmountable however.

There lies the rub. If you push to much of the burden out to homeowners they just might start going off the grid. A little in improvement in battery or other storage tech and it could happen.

At least in the US this will not happen because it is unlawful. The permit for residency requires a grid connection whether you use it or not. Without it, the house is condemned. Presumably this is because unless everybody within a specific area subscribes to the service, it will become uneconomical to provide.

The solution as I see it is to break the grid connection charge out from the power consumption charge. Everybody pays the former but only those who use more power than they return use the later.
