Are you really going to get up at 3AM to do laundry? I doubt it.

No of course you are not going to get up at 3AM to do laundry. You would fill the washer at night and it would keep tabs on the electricity rates, running when it gets below a certain price (or when it's getting late and the wash needs to start to get it done before you want to take it out).

Even if you have a timer are you going to leave your wet cloths in the washer till you get up?

Yes. I do that often. I am not sitting there waiting till the washer is finally done. I do something else, like working or sleeping.

You might not remember and those cloths will sit for another ten hours.

That rarely happens and does not harm the clothes. If it would happen often or would harm the clothes I would simply set a calendar item to warn me to get it out.

Are you going to skip your morning shower because it will cost you a dollar extra?

No. I heat my shower water with natural gas. Gas has little storage issues.
If I would use electricity for that and prices would be flexible then I would switch to a water heater with tank that would heat the water when it's cheap to do so, assuming the energy loss due to cooling would not surpass the gains from the time shift.

Another solution is the freezer and the airco. Both can run max at the moment the electricity is required, since both appliances are meant for uses that can handle a couple of degrees delta. Set some limits to them and they would run mostly when the power is cheap.
Electric cars: Most electric cars only need to charge a few hours a night. If you set it so it charges when electricity is cheap then the charging is cheap.

Large users are even more important. Aluminium is a gorgeous metal for it's near infinite ability to be recycled, but initial production requires massive amounts of electricity. A supply following aluminium plant would save a lot.
Same with a water desalination plant.

The other issue with wind power is that it can vary uncontrollably minute by minute. This is the kind of instability that needs to be leveled out by more storage.

That's not another issue. It's exactly the same issue.
Storage does not work (yet). It's simply too much energy in a too impractical form. The load partially following the supply would reduce the need for storage. Not eliminate it, reduce it.

Most drugs are quite large molecules and not UV resistant. If it becomes a problem then we, in the Netherlands, will start installing UV installations after our sewage treatment plants. For now it is only done in large hospitals because there the medicine concentration is significantly higher. There are monitoring systems in place to test for drugs in the cleaned water after the sewage water treatment but the need to clean them out of there is just not all that big.

Now, prove that its safe.

If continuous sampling proves it confirms to both these standards it is safe.
Seriously. Any decent muncipal water supply in the Netherlands continously monitors not only for baterial cultures but also PH and various chemical concentrations. If a test fails there is a major problem. I haven't had any trouble with our water (all toilet to tap) in my 30 years. The problems I heard of were things like broken pipes where mud got into the water. That'll give you bacteria.

Memory effect is exactly what happens if you recharge those old NiMH batteries before they were empty.
Modern phones have Li chemistry batteries. They behave quite different: discharge them till empty and they die. Your usual behavior should be to charge them before they are half empty if you want them to last. Emptying them to 5% (when the phone tells you the battery is empty and will shut down) can be done once in a while, sure, but for battery life it should not be the default way of working.
Treat a NiMH the way you should treat a Li-ion and it dies soon. Treat a Li-ion the way you should treat a NiMH and it dies soon.

Logitech is a decent company. You don't get that level of support everywhere.
And Windows installer going TU is going to be difficult to fix in any case. It doesn't happen often and reinstalling Windows seems like a good solution to fix a part of the Windows OS. Since it doesn't happen often I can't imagine there being a decent business case for making a separate windows installer installer beyond re-installing the OS. There will always be edge cases.
Now for why Windows STILL does not make separate data and OS partitions by default is beyond me. On occasion you need to re-install the OS. It's not what you want but it happens. Thus the default should be that re-installing the OS does not clean out the family pictures. Even though these should be on multiple backups.

Comment Re:So alternating strips and 2 voltages (Score 1) 75

It doesn't need to stay in place. In fact in TFA the tech is used in a racetrack for model cars. The rectifiers are there so the polarity of the input of each dot can switch without the output changing. If you make the alternating strips pad big enough it will be able to handle a lot of shifting around during driving. If you place it into a tray so the phone bumps into the edge of the tray before loosing contact with the pad then you've got the major problems solved unless you drive so aggressively everything has to be bolted in place anyway or you have an accident.
The tech is simple, yes, but I see that as an advantage.

The major losses are not in the DC-AC conversion nor in the AC-DC conversion. Both are usually done with high efficiency. The losses are in bridging the 1 mm air gap between the transmitting coil and the receiving coil and the presence of any other conducting material nearby. You see when the Qi charger (or whatever tech) transmits it's power over that gap some of it leaks out through the side. That leaking field starts to induce current in whatever conducting material it encounters. Those are your losses and they scale up with something like the third or fourth power of the distance between the emitting and the receiving coils.

By the way, the recieving end of OpenDots treats the power as AC, as it feeds it through a similar rectifier, in order to correct for polarity changes. These losses are not removed.
The are not a simple percentile loss however. On high power installations (like car charger) this rectifier would not be a simple Shotkey diode rectifier. It would be a sensing circuit with mosfets to switch the connections. Those are more expensive and have make no sense in low power applications but for the charging of a car using a mosfet rectifier makes sense.
You see, even Shotkey diodes have a 0.2V voltage drop over them. With a 40A charging current this means 8 W is continuously turned into heat by the diodes. The mosfet rectifier needs some power to work but that is in the order of 0.1 W, depending on the number of contact points.
