Remember all those complaints of kids getting scalded and burned from hot water? No, don't remember.
Kids learn around three how to use the water tap. One tap is red coloured for hot (and it is on the right side), the other one is blue coloured for col (and is on the left side).
If a kid burns his hands, after the second or third time it either remembers: parent told me not to use the water alone, or it remembers how to mix hot and cold water to a level it likes. (However if you have your hot water set to temperatures above 65C then you are probably an idiot)
But in our times that is no longer relevant as water is not stored in a boiler but heated on demand with a gas fire... so I have set the temperature of my hot water to roughly 45C.
or warehoused them until the market was ripe then sold them with minor retrofits to 3rd world countries over the last decade. Considering that there is no 3rd world anymore since 30 or more years, I wonder to which countries you are referring. Considering that I live partly in Thailand, which you perhaps mean with "3rd world country"... selling decades old ACs is illegal here, just like in nearly every other country of the world. And why would one buy an AC for $100 that uses more current than the local power plant can provide when he gets one for $110 that only uses half the power?
we also have inefficient AC units on the market. This is true everywhere in the world. No it is not. In most parts of the world, the sale of inefficient ones is forbidden.
Why do you insist to misunderstand me? No, they don't. The price of electricity for example is a good gauge for this. If the system is cheaper you're not paying as much for maintenance because it doesn't require the specialists. With a lower cost per kWh, rounded out with tax benefits you can come out a head. Obviously that has nothing to do with buying a new AC... neither in your country nor in the developing world.
If you buy a new AC now, the price for an efficient or inefficient is nearly the same. There is no material or construction cost hidden in it that makes one more expensive than the other.
The rest of your post... no idea. If you are addicted to AC you should perhaps move to a place where AC is cheap, power is cheap or a place where you don't need one?
As I said: your information is completely outdated. Feed in Tariffs are very low at the moment, and get reduced by 0.5cent per year.
Solar panels still have an efficiency of 80% after 30 years. Again: your information is minimum 30 to 40 years outdated.
Good luck on the warranty, since those companies have long since gone out of business too. Unlikely. And it would not matter anyway as they pay into the warranty fond/insurance and some other company fixes the problem. Sigh... americans....
The name sake is that they got infected due to showering in their barracks in France because the water never was hot enough and the Legionnells lived in the water tanks. That is actually where they live, in open water, small puddles, home irrigation systems etc.
To get an AC duct infected by Legionnells, the AC must be in a pretty odd condition.
Nuclear cannot do peaking That is not even a formally correct english sentence. Yes, they can. Actually they do all the time. Nuclear power plants in germany run at peak performance, or close to it, at about 95% peak... You see: when you realise what base load means: that a base load power plant is running at its peak. Then stupid catch phrases like "can't do peak", make no sense at all.
You probably meant: load following.... that in the end depends on the design of the reactor. The existing german ones are not designed for load following.
which is why Germany dismantled most of its hydro "energy storage" plants You read to much Bloomberg... Care to point out which pumped storage plant Germany is dismantling? Or did yo mix it up with nuke plants, those we are dismantling...
dismantling... its hydro "energy storage" plants even as it was building up wind.
But you do know that most pumped storage is in the middle high german areas and the high german areas while the new wind plants are all off shore in the northern sea? So: to build up a pumped storage plant to "cover" for an off shore wind park, we also would need transport grid capacity. Makes much more sense to sell/transport it to Norway. Oh... that is actually what we do. Surprise surprise.
Hint: there never was a single pumped storage plant build or even planned to accommodate the expansion of wind power.
Stop playing energy expert, moron. Or especially "I know everything about germans energy infrastructure". You know nothing.
is because rooftops everywhere are pretty much covered with PV cells. It is not even 1% of rooftops that are covered with solar cells, probably not even a half a percent.
The cost to recoup the initial costs are over a period of 20-30 years(the pv panel life is around 25 years). No idea about the already existing plants.
However, if I invest now 10,000 into a roof top solar plant with battery storage and join a virtual power plant for reserve power/balancing power, I will earn over a course of 20 years 10,000. Earn! Not safe in costs, but earn!
Your idea about costs of solar panels are completely outdated.
(the pv panel life is around 25 years) The warranty is 30 years. They basically live for ever. No idea where this retarded "panel life is _" comes from. If it does not get destroyed by hail (and for that you need a big bunch of hail) ripped from the roof by an Orkan (that are our Hurricanes) burned or has rotting connections because of a bad day during manufactoring: they hold for ever. Sure they degrade... but that stops around 80% original peak capacity.
This is reposted and repeated on/. so often since 10 or more years: it should be common knowledge by now.
and in worst cases nasty crap like legionaries starts breeding in the HVAC system. Legionaries live in water. So first question is: how did they get there? I mean into your heating system. Secondly, if they are only in the heating system: who cares? The problem would be if they are in the hot water for bathing and showering. That is easy overcome by heating up the water above 60C... that should be the normal case.
Legionaries are problem in institutions that keep huge amounts of hot water ready but don't make it hot enough as in a soldiers barrack or a swimming hall. At home: close to impossible to have some.
ACs are about as good as they can get right now, especially in developing countries. That is partly true. The most savings you had if old ACs would be replaced by new ones: in the developed world!!
A 3 times cost of energy in per unit to cool is acceptable because a more efficient system costs 15x per unit more. That is nonsense. They cost exactly the same.
Japan doesn't have the same kind of access as other nations to coal, wind, hydro, solar, or whatever to provide their energy needs.
Sorry, blindseer. You honour your name again.
WHY DON'T YOU LOOK ON A MAP TO SEE WHERE JAPAN ACTUALLY IS?
Japan is predestined to be run on Wind and Solar.
many nations will face the same problems as energy demands grow with development and access to oil and coal thins out. Energy demand in the first world, and that includes Japan: is not growing!!!
The old designs I'm aware of, and that are those we have since the 50s and 60s and 70s in Germany have below the containment vessel a "special designed" bath tub that is supposed to capture molten fuel and distribute it over a huge area to cool it down so far that it is solid and can not melt through into the ground water.
A quick Google search tells me that there's easily 100 million domestic (not necessarily "domesticated", as in always confined to a house) cats in the USA.
Yeah, and those who kill birds are the minority.
Again: to make your numbers fit: every cat would need to contribute a huge deal in bird kills, but they don't.
Well, my 12" (hm or is it a 10"... don't remember, have it at my fathers place) G4 PowerBook Pro can no longer join WIFI networks as it is still running OS X 10.3 or 10.4 and either the OS or the hardware itself does not support WPA2. Besides that, it is running just fine.
One confusing part about names are: they can change, the simplest case is marriage.
Now I worked on a software for planning and organizing schools. Classes, students/pupils and teachers. A school year consists of classes like 5a, 5b, 5c and 6a, 6b, 6c and so on. Depending on the grade as in 5th versus 6th grade, a class has a set of courses/topics. Obviously in Germany minimum 2 different religious courses, often more (as islam and judaism is now mandatory in schools for students of that religion, years ago only protestants and catholics had mandatory religion classes in school).
E.g. 5th grade has "natural science" and 6th grade has physics and chemistry instead.
So, what happens at the end of a school year is: you copy the whole roster of topics. So 5a of the year 2018 becomes an empty 5a for the year 2019. Same for 6a etc.
Then you promote the students from the 5a/2018 classes to 6a/2019 (supposed they passed). You assign teachers to the classes. If they had an english teacher in 5a who can teach 6a, he likely sticks with the class. For physics and chemistry you have to pick one.
Now back to the topic of names. For some reason (in the software I was working on) we had a bad glitch when a teacher changed his name. Creating a new school year (see above: first we copy the empty roaster of grades versus topics, then we assign - copies of - teachers) leaded to duplication of the master teacher instance.
Anyway: if you look back on your paper copies of your report card/school report, you obviously see the old names of your teachers. Now you lose your records and request replacements/duplicates. Will they have the original names or the actual names after (several?) marriage(s)?
Then again: that problem is now solved in the software. However students stay in "high school" (Gymnasium) till grade 13. So many of them easy are 18 or 19. If one repeated a grade, even 20. That means: one could marry in 12th grade, actually like a teacher, in the middle of the school year...
So Mrs Smith in 11th grade is now Mrs Miller in 12th grade...
Stuff like this could be easily modeled with the temporal extensions modern databases have, but no one is using them...
The new passports are biometric. That means they contain fingerprint scans.
If the photo half assed resembles you and you put the passport into a scanner and hold your finger over the finger print scanner: what exactly do you think border patrol is going to do? They wave you through!
After all this is still a genuine passport with the correct name matching the finger prints...
What makes time extra difficult is that so many people assume that time is easy. Exactly!
And because people mistakenly assume it is easy, even very very smart people whom you would probably say are reasonably careful will get it wrong surprisingly often. Yeah, somewhere is a web site with all the "misconceptions about time", they also have some other topics, like the misconceptions of "Names of Humans".

if there's airborne legionaries
There are no airborne legionaries, which part of: they live in luke warm water, did you not get yet?
And how should a legionaries or its spores, move through a closed pressure valve? Or against the exiting vapour/water through an open valve?
some type of outbreak Of mold.
You don't see it very much here in western countries, but other places? Yep.
Sure, we believe you. You are a wise man who traveled a lot.
No one has hot water tanks that are so cold that they don't kill bacteria. (*facepalm*)
BTW: Legionells are not bacteria, just in case you wondered ...

Unfortunately the better technology is not always winning at the market :(
But many architectures are remotely similar to 68k ... ARM, SPARC, PowerPC ...
I guess even modern x86 copied much of it :D (never dug into the current ISA)
Two men will have 25% female children, 50% male children and 25% children with YY chromosomes. :D
You are right.
I realized this after I clicked send
An offspring from tow males would not have an X chromosome.
I doubt they even would grow in a jar.
No one owes Wikipedia anything for using it.
In what fucked up society did you grow up that you don't owe the courtesy of indicating who you quote?
