.. I think it's trivial, that its just a different version of the well known peltier effect based heater/cooler units you use when buying a cooler for keeping beverages cool when underway.
Because of the "250 pân" pairs from the abstract this is how peltier cooler/heater pads are built up, and I think you can already get around 0,8 % effeciency with commonly availiable off the shelf components.
You can use these modules yourself to extract electric energy from a temperature differential.
Don't get me wrong, if it works and will not have a negative effect it is basically not an issue, from a functional POV.
Except this is an "Apple product", you exactly don't want a "very slight bend" that.
Judging from the photos that "very slight bend", is just an understatement, what would then be a slight bend, roughly everything below 10Â ?
You want "quallity" in the real sense and not something a chinese cheap-factory spits gadgets out like a machine gun spits bullets - wide spread hit area, and that lands on the very cheap section on ebay.
And before going into production there is a test production - where the devices go into a landfill or into a furnace - and this must have happened there, somebody must have recognized it.
And it seems - this is speculation - someone at Apple QAgetting oked from supperiors, decided to go with it.
Apple stands for high quallity visual, happtic as well as working.
This simply does not justify the higher price of Apple products.
Because then you could also go with a 100$ cheap Android run-off-the-mill tablet - with all your private data siphoned to china.
Actually in Germany you could - till around 1 year ago - get a pre-paid SIM for example from Aldi/"AldiTalk" without showing your ID, and you didn't even needed it for activation - this has changed.
However in the U.S.A. knowing from media coverage that the FBI has a great deal of possibilities to prosecute, I would think that they get the IMEI/IMSI logs from a cell-tower and then they got a location and perhaps a route somebody drives, than you can IMSI-Catch someone and pin-point the location pretty exact, and when you catch him with that exact phone with the "incriminating content"you have pretty hard evidence, because its likely that a burner phone is just a flimsy Android device to crack open for a whole lot less than an iPhone.
So basically, I find it hard to believe that there were no big busts till now, but perhaps they want to stuff as many criminals as they can get into their bucket.
Yeah, but phone IMEI/IMSI -> logged cell tower - ok you can get a burner phone, but the FBI could pin-point your location, or come near it and setup an IMSI-Catcher (getting your position even more acurate) -> knowing where you are and bust you.
Please, don't call it a dynamo:) call it a generator - dynamo reminds me too much of a bicycle.
generators using rare earth magnets
But you are "mostly" wrong on the rare earth magnets, some wind turbines use them in so called permanent excited generators, were the permanent excitation comes from rare earth magnets. Those generators are also synchronous generators, all their electrical power output needs to be channeled through a frequency converter to make it grid compatible.
Rare earth magnets have a very high flux density making it possible to build very small and light generators -> saving on other materials.
generators not using rare earth magnets
externally excited synchronous generators For example wind power company Enercon is famous for using direct drive turbines with a huge multipole synchronous generator - but stator and rotor coils - as the name implies are made from copper and dynamo sheets
Also smaller generator designs are possible when using a gearbox to transform torque and rpm.
DFIG - no permanent excitation The doubly fed induction generator is also generator type that uses no rare earths and it is the widely used(work horse of the wind power industry), stator and rotor are built from copper and "âZdynamo sheets"
In contrast to the synchronous generator the excitation is done externally by a frequency converter, thus only about 1/3 of the electrical power is channeled through the converter (it can be built smaller compared to the syn. gen case). However this type of generator cannot "jump start"(black boot) a grid as the frequency converter needs power to excite the generator.
And due to new developments in converter technology DFIGs are getting much attention again as this improved converter control makes it possible again that newer DFIG installations are compliant with newer grid codes (grid code specific requirement on grid connected power plants how to "behave" during grid faults and also normal operation)
squirrel cage - no permanent excitation Newer concepts use a simple asynchronous generator with squirrel cage (short-circuited rotor) as this generator is really "simple simple".
All the electrical power is fed into a frequency converter that transforms it to grid compatible electrical power.
For such a generator to produce energy the stator needs to be connected to a "grid" provided by the frequency converter.
Actually I'm worried about China too, but don't your points are also valid for the "U.S.A."
- I mean intellectual property (NSA / Enercon) - State subsidies vs. Custom Duties - students tools of the government (and if students go on and work for NSA and CIA and implement things like egoistic giraffe).
Well, only those who are without sin should throw the first stone.
Except critisizing the government will not land you in internment camps or prison in the U.S. that's the difference.
I'm sure people would love to vote for a candidate, boasting about groping womens genitals and doing such a bad job as being recorded with that statement?
And actually they did, what will this now tell about if these people would live to see children or women being raped in the open?
It protects the hoster against a subpeona, because he will surrender all data, but at least the backup is still encrypted.
To decrypt it you would need to get to the person, who has the private key, in his/her possession and use violence or just force him to surrender the private key.
And a darkweb hoster tries not to know who the customer is:)
Perhaps one-way is the wrong term, perhaps "Postbox"-Backups are a better term?
I mean, we have the tools to create a public & private key used for asymetric encryption.
With my public-key I can encrypt data and without the private key this data can't be decrypted?
How to use these keys in backup and restoration? So when I would generate such a key-pair and put the public key into the backup service of this hosting provider, the data could be backed up and gets encrypted with the public-key. But nobody except the owner of the private key could decrypt it.
The owner of the private key should not be the hosting provider:)
postbox It is like a postbox, you can put letters in, however only the mailman can open the box with his key and get the letters out. (disclaimer: metaphorically speaking, not including access by lock picking, explosives, extortion, and so on..)
Another application Naturally it would also be possible to equip an email service with this technique, the server receives an email and without storing it anywhere outside RAM, it will be encrypted with your "public" key first and then stored inside your mailbox. You receive it and decrypt it locally.
This way a person getting access to the eMail-Account without the private key will only get encrypted data.
Or am I getting something wrong?
I know if we would live in a perfect world we all would do key-exchanges and signing and ofc singing and dancing. But this world is far from perfect.
I don't think that this is the real intent, because the article says "domestic and foreign games" meaning also games from chinese companies.
When you follow the development in the peoples republic of china (PRC) you can guess their intent pretty well. Western lifestyle is more and more seen as "unwanted" influence and a deteroration of "the"(*) chinese culture and lifestyle. This view expressed by the leadership elite and headlined by Xi Jinping. In contrast most people from china that have earned their capitalistic share have a certain tendency to a western lifestyle (increasing demand for milk, western made cars for example as symbols of their wealth)
Interstingly when people from china have worked in western countries and adapted a certain western lifestyle and work ethic they are named "bananas" - yellow on the outside, white on the inside - as an insult.
The leadership elite fears that influence because it has the potential of breaking the perceived picture of china as being "the one and only china"(*). This nationalistic -united- china is what the leadership wants because it gives strength - military strength, wealth. (see island expansion, ignorance of international law and judgement)
Disscent now more than in the last 15-20 yrs. is viewed upon as a threat to this nationalistic ideal. (see islamic religous life more and more oppressed in Xinjiang). Internment in reeducation camps has been revived. (these camps were not seen in china for quite some time)
And video games are just part of the western culture and "some" gamers do not exercise, getting overweight, underperform in school. No exercise and overweight = danger to the military strength, underperform in school = threat to the academic uprising of china.
(*) "the" china - despite that picture, china is a huge country with diverse cultural heritage, food, religion.
Because the current behaviour of Russia and China isn't very friendly to say the least, it's very aggressive. And with such a whimp as a president who just needs to hear the magic words and he will give you the droll lock and roll over for Putin like a pet for his owner.
And please don't compare the behaviour of Russia or China to US-Israel-stuxnet. On the one side nobody in his right mind wants to have a nuclear armed Iran and on the other the action taken was precisely directed towards one goal, uran enrichment and not against the goverment system of iran.
It starts in the design phase. When you design your "Object"(automobile for example) without certain constraints an automation unit can easily work within - then it needs manual labour because "HI" can adapt easily - or try your luck with CV Systems. However computer 3D-Vision is much more complex and error prone in contrast to for example state of the art 2D-Vision systems where you can really high speed place & sort and do things.
I think it's good that Elon Musk is true about that fact - we didnt know what we did - however I would guess he was told that the design wasn't ready for automation, and most likely that person got demoted to janitor or was fired.
From all information I have on Elon Musk, my picture of him tells me that has the same problem as Trump. He is impervious to counciling from people that actually know better and are more "earthbound".
This character flaw is actually very dangerous for Tesla, because we actually had a near miss of a collapsing Tesla company. I personally would not like to see that because Tesla is a strong driver that has shaken up the automobile combustion gallore.
Blades The "huge" blades weight is actually a very small amount of the whole weight.
But it's true that composites cannot be "recycled" they can be broken appart and cut and later shreded and then can be a.) burned for example in the cement industry the residue being created that cannot burn is normal to this process what so ever. b.) used as a supplement for tarmac and even concrete
So yes blades are a bit of a hassle. And like anything else nothing is 100% green, what is important is the overall sum.
How can you get rid of a turbine: Set a charge to the tower foot to cut or buckle it and blow it up 10s later the visible part of the wind turbine is gone.
You should however drain the gear oil beforehand otherwise you have an oil spill.
And well that waste that's now laying on the ground is the most of it is steel and cast iron(easy to recycle), the nacelle cover is mostly composite and can be treated like the blades, you can recycle the transformer(copper). Converters are electric waste.
What really is of a hassle and what's expensive to remove is the foundation made from reinforced concrete, for example in germany just the top of the foundation is grinded off.
The foundation however has a sealing effect on the ground so it would be better to remove it. But to put it into perspective the amount of sealing a turbine foundation does is realatively small compared to for example roads and highways.
In germany its regulartory that you as the owner/operator of a turbine need to create an escrow fund to have the turbine removed when the lifetime has ended.
