This is excellent. At my company we are not allowed to have phones with cameras, so now I am juggling my private smartphone and a kick-ass Nokia 101 which I take to my desk.
If I could build a smartphone with a decent touchscreen, no camera, and dual sim capabilities I'd be really happy.
I would be extremely happy of being able to play the next Mario on something else than a Nintendo console. I bought the Wii just for Super Mario Wii, I loved the game, but now I have a white piece of plastic doing nothing underneath my TV.
It's not going to happen, but it would be very nice.
Long answer, not in the foreseeable future, unless someone strikes their best luck. Metal air batteries (lithium in particular) suffer from a bajillion problem that are not even close to solving in the lab, let alone in a device. Someone might within 5 years come up with a working lab demonstrator, but something with enough power to move a car (and a "sports" car as a Tesla at that) is way off, considering the current state of research. So considering that the patents will be expired when the technology might be ready, it's just empty internet talk.
Here in Europe it is widespread belief that the fact that 1 and 2 euros are in coins are a reason for inflation. You think twice before spending a bill, while psychologically a coin is easier to part with. It does happen quite often to have 10-20eur in coins so it's probably not all wrong.
The more I use Android the more I LOVE my N9 the more I hate Nokia for killing it. I know there is a lot of politics involved (not last the usual OSS community circle jerking) but the capabilities of that OS over anything else are amazing.
Yes, it's trollish, but if you have ever had to do business with Japan you will know how hard it is to carry out any sort of meaningful conversation without resorting to a professional translator.
The best is having a one hour long meeting in English and then have your Japanese boss redo the meeting in Japanese when you have left the room.
I have been suggesting my employer for years that introducing Japanese classes for the Western staff would be the single most effective improvement that could be done to my company, but alas, it costs money, and companies love their money.
Just to be pedantic, he invented Nickel-Metal Hydride batteries which happen to be used in most hybrids, but of course are used in a million other places as well. RIP.
I really fail to understand how this data is used and if anyone actually checks it or if it is kept in order to incriminate you later. See what happened in Toulouse last week: a man who went in and out Afghanistan and Pakistan, was known to the police, went in and out of jail a couple of times, was known to frequent an extremist group, still managed to kill children in a school and keep the police busy for two days under siege. Shouldn't he have been stopped before?
Thank you, I would mod you up if I could:) I might get a SIM card from T-Mobile and invest 10$ just to be reachable for free. Ans yes, our phones are GSM with SIM cards.
I will visit the US this summer from Europe. Can anyone point me to a link where I can get some maps/explanations about roaming in the US? I am horrendously confused about the US market and their current standards. I will come with a N9 and an iPhone so I should be fine, but I'd like to be sure ahead of the time.
Electrolyte of Li-ion battery completely freezes somewhere around -30C. Degradation of performance (i.e. increase in resistance of the electrolyte and subsequent decrease of available power) starts sooner, but there are additives for that. I guess there are few places on earth where a roadster is left parked for an extensive period of time in order for the whole pack to freeze.
Well technically towing an electric vehicle, missing a clutch, would make it a generator, which could possibly damage the battery. However there is a youtube video showing a Nissan Leaf being towed and the battery being recharged. Don't try this at home!
Another option with the Tesla could be to lift the back wheels and tow it with the front wheels on the ground, unless there is some regenerative braking system which still acts as a generator. And yes, you want to lock the wheels if you do that.
When I read the blog article I thought exactly the same thing. Cells left to self-discharge will not go below their thermodynamic equilibrium, which is more or less the potential at which they are built (remember, Li-ion batteries when assembled are discharged by nature). There is no danger of damaging the cells when self-discharge occurs. Another issue is when the cells are actively overdischarged, however a Li-ion battery is more likely to explode due to overcharge (plating of Li metal at the negative electrode) than overcharge (insertion of too much lithium in the cathode and electrolyte depletion).
Most likely the BMS is refusing to come back to life unless hooked up to a secret Tesla computer, but I guess the packs can be refurbished.
Also, kudos to the idiot recharging the car with a 30m cable extension (that's what 100 feet is, right?).
Interesting, but how much energy does it take to run this thing?
From the abstract: "Here, we demonstrate an energy consumption of 0.29 Wh lâ"1 for the removal of 25% salt using this novel desalination battery, which is promising when compared to reverse osmosis ( 0.2 Wh lâ"1), the most efficient technique presently available."
My cousin and her wife both work in tourism, so they fashioned their invites as plane tickets. This confused a large number of people. My mom for example threw the invitation straight in the bin, thinking it was some mass mailing.
Good question. Short answer, I don't know for sure. Long answer, see below.
For batteries packaged in an aluminum can, I can't see a big impact. For batteries packaged in a soft pouch (such as the iPhone's, I believe) it might be more of an issue. The point of the problem is the liquid electrolyte, which is generally formed by two main solvents, Ethylene Carbonate and Dimethyl Carbonate. EC is a solid at room temperature (mp around 36C), while DMC is a liquid with a reasonably high boiling point (90C IIRC). I don't think that the reduced pressure in the aircraft is enough to make so much DMC evaporate as to create excessive pressure in the packaging. Which is however designed to fail if too much pressure is built up, and Li-ion batteries are assembled in the discharged state.
Exactly what is the difference between a no-name Chinese battery, and a named Chinese battery, besides cost?
In Japan and South Korea battery production is almost fully automatic and conducted in well controlled conditions. This is a continuous process in which a long sheet of electrode material is assembled in a roll. In China, on the other hand, many batteries are produced by hand by stacking discrete smaller sheets of electrode, then putting the stack in a container (be it an aluminum can or a soft pouch). You can imagine that this stacking can be less than perfect and a shortcircuit due do misalignment or some foreign body is always possible. Of course not all batteries are produced this way, but some are.
Between this, the Volt battery going up in flames and on a smaller scale the Belgian Post e-bikes catching fire, I am very worried about the fast deployment of Li-ion batteries in many fields. I am a researcher in Li-ion batteries, and I know how dangerous those little buggers can be, but also how many efforts are done to make them safer. However, you can't take bad manufacturing out of the equation, and you should always ask yourself why a no-name chinese battery costs 1/3 of the original battery.
It would be nice to know if the phone was ever dropped, or its battery replaced at any point, or if a non-standard charger was used.
I agree that most emails are useless (starting from those which are sent just FYI, but are still distracting and interrupting the workflow). However, if there is one thing I learnt by working in a megacorporation, is that _everything_ has to be in writing at some point. So many times a colleague or supplier will say "sure, we'll do that no problem" and then weeks go by, without anyone remembering. For accountability, email is still the way to go.

In fact, it's exactly the same tech. Tesla uses laptop batteries for their vehicles.

The US Government has been out-lobbied by Korean lobbyists? Or is Samsung's plan much bigger than Apple thought?

This. The N9 app store is pretty much dead and it's quite understandable why. If Sailfish has some success then we'll see more apps developed.

If you like the shape of the phone, just get an N9 :)
And yes, it runs Linux!
As does my N9.
