It's called Maximum Power Point Tracking (or MPPT) and has been around for a long long time.
Since there is mention of 'windmill efficiency' that talks about the end-to-end efficiency, which includes Betz' limit.
Simply restated getting ~60% of the power going in to the system as a whole can be harvested (100% - Betz' - losses), at low power levels you'll need some trickery to maximize this (think of it as impedance matching) but this is not in any way 'new'.
One commercial gearbox less machine in the 2 Megawatt range is the Enercon, it features MPPT.
been there, done that, as have *countless* others. Really, I don't know how this even begins to classify as 'new'.
Automatic star-delta switches have been done, same with electronic versions that do voltage conversion so that the maximum amount of power flows to the grid (or the batteries for off-grid systems).
Wind power is *full* of snake oil companies and investor scams. As well as people that try to pass off old stuff as new.
Spot on. The 'windmills kill birds' argument is just another way for the 'we're against everything' crowd to try to stop any kind of change, for better or worse.
That's called maximum power point tracking and is pretty old in concept and in actual use today in many thousands of wind and / or solar installations.
He has a point, even if 'pics' won't make much difference the vapourware will stick. There is this thing called Betz' law and it is pretty specific about how much energy you can extract from any moving medium.
hm... There has to be the seed for an alternative community model in there somewhere. For the life of me I can't find it, I only end up with people that can communicate one-way, someone help me out here ?
What an unbelievable load of crap. The biggest difference between former east and west Germans (now there are only Germans) is that they were less educated and a lot more poor. If you think whatever country you live in does not have a 'secret police', whatever it's name then you're really not informed as well as you make it seem.
East Germany was very much under the boot of the USSR, just like Poland, Hungary and a host of other countries that are now part of - or about to become part of - the EU. America and the rest of Europe carry at least as much responsibility in the creation of the monster called Nazism as do the Germans, but it would take a politician with some real brass ones to openly admit that. The Germans have been pushed into a position of collective guilt which the current generation should carry absolutely no blame for. Since you're posting on/. I assume you are not one of the last remaining people that fought in the resistance, so you also had no dog in that fight.
Be objective.
With 99% of the people in those countries there is absolutely nothing wrong, maybe they could do with a bit of education, about the consequences of voting blindly and being influenced by propaganda.
Psychopaths exist in any culture, all it takes is a good dose of fear, some propaganda and a charismatic leader to make a majority of the populace in almost any country in the world vote for a totalitarian regime. Look at what has been happening in the US over the last 8 years.
Once you've got that it will take major force from outside or a revolution to get rid of them again.
Go see the movie 'the wave' (http://www.imdb.com/title/tt0083316/) and read some history books.
The seriously ugly thread that you see running through Germany is running through most of society, like it or not.
The real trickery is in the interconnects and the cooling, the cpu's are probably discounted quite a bit but I doubt they're the biggest item on the tab.
So, let me get this straight: If someone writes something you think is not true he or she is an 'idiot', whereas if you write something that you admit wasn't true you 'have been misled' ?
I don't think you have a clue how such a machine works. To simulate a non-trivially-parallelizable system like an x86_64 on it you could run your simulation on exactly the same number of cpu's as you have cores in your simulated cpu, or less (for a much easier to program simulation).
Clusters such as these are *built* using standard hardware, in this case a (rather large) bunch of AMD opterons.
If you can show me how to run 'Crysis on Vista' faster on rack with 10 pcs without rewriting either (and I did not see a cluster version of either) then your claim stands, otherwise it just confuses the issue of what a super computer is and what it can do.
A typical task for a computer such as this one has the main task broken up into a large number of subtasks so that each CPU in the cluster can work on a small portion of the problem at the same time. This results in a speedup of some fraction of the total number of cpus versus the same time to run the problem on a single cpu. To achieve any meaningful speedup you have to be able to break the problem up like this, otherwise all that shiny hardware will just end up waiting for each other.
I would suggest that you can't be sure of that, especially not for firstborns. You'll have to do some math on an awful lot of people and when you do so you'll make quite a few enemies and find out that a large number of firstborns were conceived before their parents married, in fact were the reason their parents married.
Try it!
(and if you're a firstborn then you are the obvious test case;) )
of the woman in the movie 'the corporation' that thought it was a great idea to get children to 'nag their parents more effective'. I just love the advertising business. not.
Canada is full of idiotic laws like this, unfortunately. It's one of the nicest countries in the world but Canadian politics and the legal system are as bad as they come. The police enforcing these laws varies from scum (smalltown cops) to very professional (RCMP) and everything in between.
I've often compared Canada with a giant corporation that simply exists to squeeze dollars out of it's employees. It's the only country in the world that I know of that has started off as a corporation (the hudson bay company) and it certainly shows in the way it deals with its 'citizens'.
For example, in Canada it is illegal to receive satellite broadcasts from other countries because that means you're not paying the local competitor.
I do not mean that they make it illegal to illegally decode these signals, I mean that it is illegal to decode 'foreign' signals even if you're paying for them.
they're not, but you are not likely going to get arrested for using them, only for dealing them. Having lived there for 28 years of my life I can tell you that there is indeed a drug problem in Amsterdam but it's mostly limited to foreigners that come there to use drugs the 'mokummers' that use (hard)drugs do so in the privacy of their homes for the most part, though, of course there are exceptions. If the foreigners would have access to drugs in their own countries the drug problem in Amsterdam would probably be less than 10% of what it is today. (as with all internet statistics I just made this one up on the spot)/me is not a drug user, hasn't smoked or drank ever, in general is a very boring guy but doesn't care one bit whether someone else does or does not use drugs, live & let live.
The pope is a Christian too, but he's *NOT* a creationist. Your argument fails horribly. Large portions of the Christian religion have adopted the theory of Evolution. They *also* believe in God, they do not believe in a literal interpretation of the book of Genesis.

Yep, but since the most efficient turbines are already at more than half Betz' limit this is simply not going to work.

not yet - outside of the lab - but when you'll see them they'll be subtractive for sure, e-ink is no different in this respect than regular ink.
Think of it as the difference between mixing with light sources (CRT's, LCD's, plasma) and reflectors (paper & regular ink, e-ink).
The OLPC uses an LCD, so has RGB, it's nothing to do with 'cost', it's everything to do with the basic technology.
