You should have stopped writing after your first line :)

The rest of your comment is bollocks, e.g. how do you come to the idea that solar plants generate square waves?

Or your 12V versus 5V example ... don't even get what you want to say with 'plugging a 12V supply into a 5V SUPPLY ...'

Your explanation might make sense on the first glance, but is nevertheless wrong.

For a power company there is absolutely no difference whether YOUR washing machine stops washing and they have to get rid of the 1kW that machine was draining OR YOUR solar plant suddenly increases its output by 1kW.

The grid is controlled by only one thing: the grid frequency. If the frequency drops the power plants need to generate more power. If the frequency increases the excess power needs to go somewhere, either in pumped storage, or you power down conventionals.

The whole explanation of that energy company spokesman is utter nonsense.

They perfectly know how much solar power is installed to their grid, they perfectly know the weather report, they perfectly know what load curve on the grid was last year etc. etc. In other words, even if there is no regulation for solar plant owners to announce the connection of a plant to the grid (which I highly highly doubt) they simply can figure what is connected today by comparing their own input today with their own input from last year on a similar day etc.

The result is: they exactly know how much solar power under certain weather conditions is fed into the grid.

If they claim otherwise, they are just lying. Or do you really think countries like Germany use magic to connect house holds solar plants to the grid?

Was it an ultra light or not? If it wasn't he needed a license, I know.

If it was, I know now he does not need one in the USA, but in the rest of the world.

So perhaps you shut up if you don't know stuff?

Or be polite as I am and: simply explain stuff to the not knowing. Would make much more sense.

Best Regards

I tried googling for Karlsruhe record temperatures, and got nothing useful. Got anything?

I guess that is easier in "german" :D
This are only high temperatures, not lows for winter: http://www.wetterdienst.de/Kli... (a random first hit on google), there are plenty of towns with heat records above 40C

No idea how reliable that data is ...

Why do you say Wikipedia is incorrect ...
I did not mean incorrect, but more "not reliable" as it is edited by hobbyists. In this case it might be more problematic that records like above are are collected from more or less "official" measuring points. Which means "anecdotical" data from private points is lost (and measure points are averaged, so the 40.5C in Karlsruhe likely is an average from 36C to 44C ... or whatever, no one really knows except the guys publishing it)

Nor do I understand how you could possibly be getting far warmer temperatures than Minneapolis
Well, central Europe is in summer as well as in some winters dominated by strong long lasting high pressure zones. Long lasting implies we have an "unusual" east wind, from siberia. That brings heat in summer and cold in winter.
The principle is the same as the "arctic/polar vortex" phenomenon. No idea why this word got "fame" last year because of the "normal" cold around the big lakes in the USA/Canada. That vortex exists every year, during the whole year, and one or two additional high pressure zones influence the winter weather quite heavily.

That "vortex" exists all the time, the question is how (or how many) high pressure and low pressure areas are established in deep winter and high summer.

Bottom line you underestimate the effect of high temperature winds coming from Sibera, or even desert storms coming from Africa/Sahara, but the later only have an effect in south Germany, north of the Alps (ofc. they heat up Spain, Italy or Greece quite considerably).

Also you might miss the gulf stream.

Even Countries like the Icelands have a summer high temperature like 30C.

North Scandinavia, Trondheim e.g. see: http://www.yr.no/place/Norway/...

E.g. Trondheim minimum record is like -26C and maximum is like 35C. Even Germany is COLDER in winter, in bad winters.

There are islands around Norway at the coast, that barely get a minus temperature in winter nights, because of the gulf stream having like +10C - +12C temperature around there.

Finally, you underestimate the fact that in summer the days go longer and longer the farer north you go.

It is a difference wether your daytime is 14h (in Minnesota) or 18h or even 22h in Trondheim.

Perhaps in Minnesota the "hot phase" per year is longer, and on average hotter, but it is easy to assume the peaks are the same, well it seems the official peaks are a bit higher than in Germany, and ofc, in Norway bottom line the temperature is lower ...

Sorry, my previous attempt to answer was eaten by my iPad ... it had a few more links which I don't find now on my Mac.

Not sure if we are contradicting each other.

Veni, vidi, vici, is pronouned all three times with a W and the C is pronounced Chi. Not with an hard K but similar as in 'chilling'.

Originally Kerberos was developed on Unix, for
Unix. The level where it is is a bit tricky, as it is certainly not application level. As soon as you have Kerberos active (pronounced with a hard K btw. ;) ) every TCP/IP package, regardless of 'application' should benefit from it.

You will have a head crash on your private pack.
