Tesla Gigafactory Begins Production (reuters.com)
Thelasko writes: Right on schedule, Tesla's Gigafactory has begun production of battery cells. The fact that the factory has opened on schedule has surprised many critics of the company. Reuters reports: "Electric car maker Tesla Motors Inc has started mass production of lithium-ion battery cells at its gigafactory in Nevada along with Japan's Panasonic Corp, the company said on Wednesday. The cylindrical '2170 cells,' which will be used to power Tesla's energy storage products and the new Model 3 sedan, have been jointly designed by Tesla and Panasonic, its longstanding battery partner. The gigafactory will initially produce battery cells for the company's Powerwall 2 and Powerpack 2 energy products, Tesla said. The factory is expected to drive down the cost of battery packs by more than 30 percent, the company has said. At peak production, the gigafactory is expected to employ 6,500 workers and create between 20,000 and 30,000 additional jobs in the surrounding regions, Tesla said."
I understand that they are making these primarily for cars, but does Tesla have any plans to make consumer-friendly Lithium-ion batteries for general use? Seems like they could easily make these, and drive down the costs of these things pretty dramatically. Looking quickly on Google, general-use batteries seem to run hundreds of dollars. I'd be interested in one for various purposes if it dropped down into a $50-$100 range.
Am I the only person here who took this long to realize that Tesla cars are powered by what amounts to a shitload of flashlight batteries wired up in a tub?
It's actually an excellent system for a low price. The cells are insulated and have a cooling system so as to maintain a optimal temperature. Furthermore, as cells age and get a open/short or bad cell, the pack rewires itself around the trouble allowing it to gradually fail gracefully unlike simple packs. Finally tesla and the government want these to be cheap so they offer massive subsidies and car companies like tesla sell them at a loss so as to not turn people off with a 30 thousand dollar price tag (like it would be marked up for general purpose at a typical company). It's a good deal for the money given today's tech.
The name Gigafactory comes from the factory’s planned annual battery production capacity of 35 gigawatt-hours (GWh). “Giga” is a unit of measurement that represents “billions”. One GWh is the equivalent of generating (or consuming) one billion watts for one hour—one million times that of one kWh. https://www.tesla.com/gigafact...

... energy that has been fabricated by minerals and ores extracted by, and processed in plants powered by, fossil fuels.
God: "No, you can't get past the fucking 2nd law."
Does that include fossil nukes, hydro-fossilized or geothermalized petroleum plants?
We *can* phase out fossil fuels, just not yet but we can cut our usage drastically. We had to use other energy sources to kickstart our use of coal & oil; this is not different just on a much larger scale.

100% of your products can't be loss leaders.
Typically that makes them an excellent buy as a consumer. I don't care how they stay in business, if only all my products that I buy had this value per dollar spent I'd be much happier. Personally all that means for me is I would stay away from investment.
Man replied: "Not really, since in any scenario where that source didn't exist, neither would we. So it was pretty much guaranteed via the anthropic principle"
I don't care if it's 90,000 hectares. That lake was not my doing.
Oh, come on. The EPA won't exist in 2 years, so there won't be any superfunds to worry about. The free market will take care of it.
That said, as a TSLA shareholder, I really hope they don't have a fire...
Laptop, not flashlight.
Ok, if you want to be pedantic, laptop AND flashlight battery.. Not to mention e-cigs, bluetooth speakers, and a zillion other things the nearly ubiquitous 18650 is used for.
Now, if you'll excuse me, I have backups to corrupt.
Replying to my own post: apparently TODAY is perihelion day. Who'd have thunk?

"Why, the fax-machine ain't nothin' but a waffle-iron with a phone attached!"
For products where your relationship with the producer ends at the point of purchase (and you don't much care whether or not you will continue to be able to buy that product in the future), that makes sense.
For a lot of the more complex products (in particular cars, software, computers), however, the value of your purchase will depend strongly on its manufacturer's continued ability to exist and support that product.
i.e. if you bought a Pebble watch last month, you're probably not too happy that Pebble called it quits this month, since that means you won't be getting much in the way of support or updates in the future, and your watch might stop working entirely.

Well, then you should stop imagining things. 18650 is by far the most popular battery for nicotine vaporizing devices. Nothing else even comes close to being popular.
Now, if you'll excuse me, I have backups to corrupt.
You would imagine wrong then, the 18650 is THE cell for eCigs. I know because my brother-in-law vapes and has the things laying around everywhere, which I find mildly disturbing. Regardless, a quick Google search shows plenty of proof. http://ecigarettereviewed.com/... http://vaping360.com/top-5-186... https://www.vapinginsider.com/...
Same corporations, day in day out.
Sometimes the "news for nerds, stuff that matters" comes from some small handful of active companes, as they bring their breakthroughs into public use. Sometimes it has been AMD, Intel, Apple, Microsoft, Oracle, Sun, and so on.
Right now Tesla is big, as they finally bring the battery breakthroughs Slashdotters have been lamenting as "always N years off", to market, for electric cars and energy storage for taking houses off the grid and onto self-generated renewable energy.
Remember all the lamenting, just yesterday, about how the price breakthrough in photovoltaic solar would be useless because of the cost of storage (for night and dark weather periods) and voltage conversion? Remember how I pointed out that voltage conversion has already succumbed to Moore's Law and the battery breakthroughs were just about to come on line?
The future came today. Look out, grid utilities!
C'mon, editors, *dig* a little! The Web is a big place, cast your story nets a l'il bit wider...
The editors don't dig. The slashdot users dig and the editors chose. IMHO they were right on to post this one.
Bantam Dominique roosters crow a four-note song. Once you've heard it as "Happy BIRTHday" you can't NOT hear it that way
You're an order of magnitude off there, chief. That would be a hearing-aid battery. They're actually making 21700 cells. Tesla sometimes calls them "'21-70", but omitting the dash and concatenating the numbers makes no sense.
No big deal, I suppose, just a little typo... I still look forward to buying a $350,000 (3350 eur) Tesla Model 3, with its impressive 21 mile (3460km) range and 1550 mph (25kph) top-speed.

Pretty much. Your geek card is on probation.
When all you have is a hammer, every problem starts to look like a thumb.
If you bought a "smart watch", you have bigger problems than the company that makes them going out of business.
You are welcome on my lawn.
Sorry that's bullshit. They're not selling at a loss!
>It's actually an excellent system for a low price.
I don't think so. Bigger cells are invariably better priced per W/h except if they come in exotic sizes. Chinese themselves have switches to LiFePo4 chemistry from LiCo or LiC (conventional li-ion) for all big cells years ago. Musk and co. will have to play catch-up hard, and they will have to retool the assembly line in the future invariably unless they want to produce worse cells, at higher than the market price...
You need lots of cells to balance the pack. Li-ion are finicky. That's one reason the giga factory is so large: you need a huge inventory because (1) the cells need to age and (2) the more cells you have the easier you can find a matched set for a well balanced battery. Tesla batteries perform really well, in part because of the effort that goes into selecting the cells that go into each one.
I don't care how they stay in business
Perhaps you should. Selling below cost initially is how monopolies are created. A company can sell at a loss for a while if they know this means driving off the competition. They don't need to drive everyone off, just diminish the ability for any competition to arise to the point that they can charge a premium for a substandard product. They would be betting on the ability for them to undercut any future competition later with greater volume (lower margins) and/or some reserves in resources to outlast the competition in a price war. This might not apply to electric cars exactly since this is not the kind of fight that a small company like Tesla can win against the likes of Ford and GM.
What is another tactic, and more likely one that Tesla could employ, is the ability to sell at a loss now knowing that the customer will likely return to them for services in the future. If this means selling another car in the future then perhaps there is nothing wrong with that. If this means selling critical parts like a battery then this might be a problem. Tesla would be in a position to overcharge for the battery to make up for a loss on the initial sale. If customers somehow feel compelled to continue using an electric car then Tesla would be in a position to also overcharge for the next vehicle too.
If Tesla is able to sell below costs because of government incentives, like subsidies or lowered taxes, then you are paying for this below cost pricing even if you are never a Tesla customer.
There is no such thing as a free lunch. You are going to bear the costs in some way.
What bothers me most is when the below cost pricing is due to government interference. In that case I'm paying for some rich guy to buy a new car when I can't afford my own. This is a subsidy that takes from the poor and gives to the wealthy. All energy subsidies do this really, take from the poor to further enrich the wealthy. I'd rather I be able to keep my money, perhaps then I can afford some new windows on my house. If you want to see people saving the environment then we need to stop these subsidies so people like me can buy some new windows, attic insulation, or even just a new pair of wool socks, and not have to spend so much on heating.
I am armed because I am free. I am free because I am armed.
Yes I am, and I benefit from that directly. I see little benefit from someone else driving a new car while I don't.
I am armed because I am free. I am free because I am armed.
Also in footprint. 400000 m^2 vs 200000 m^2.

Because the cells might start a fire and when they are lying around everywhere, it is a potential fire hazard.

Indeed. Tesla has some of the most advanced battery packs on the market. It's pretty dang impressive being able to make a car with that much mass of lithium ion batteries with decade-scale lifespans operating in outdoor conditions and has an order of magnitude lower rate of fires per mile traveled than gasoline vehicles.
Also, as for how they're wired up, in case anyone is curious: individual cells are wired up in parallel "bricks" in large numbers, so that if one cell dies, it has little effect on the brick as a whole (contrast with a laptop battery with 18650 cells just in series - if one goes, the battery is dead). The bricks are connected in series into "sheets" to raise the voltage, and the sheets in turn are connected in series to make up a pack. At least that's how they did it with the Roadster; I assume the Model S is individual. Within each brick, each cell is in its own isolated can; the goal is to prevent propagating failures.
The climate control issue took some time to get right. Early Roadsters suffered from fairly high parasitic drain when the vehicle wasn't plugged in, but they refined the climate control algorithm so that they could more properly maintain the pack temperature without wasting energy. Key to maintaining cell longevity are three main factors: charge/discharge rate, depth of discharge (upper and lower), and temperature. Getting temperature right is very important. As for the other two, the cells aren't charged to their full capacity when the vehicle is at "100%", they're at 90-something percent (at least they were with the Roadster). And on your average drive you only use a very small percent of the pack capacity, so in practice it's an extremely shallow depth of discharge. Both normal driving and overnight charging are low current applications per cell; only fast charging and track duty are relatively high current (but even still you're talking at least half an hour to charge or drain most of the pack).

Nuclear power ... kills fewer people per energy produced.
FFS. If things go really, catastrophically wrong with a solar panel installation, how many people could it conceivably kill? One or two if it fell off a roof? Whereas, if things go really, catastrophically wrong with a nuclear power plant, how many people could it conceivably kill? Bearing in mind that no production pebble bed reactors are in operation anywhere.
Tilting at strawmen rather than acknowledging the actual safety concerns people have about nuclear makes you look like a shite imitation of Don Quixote.
Yeah, I'm sure they didn't bother doing any CBA or before building a $5B factory. Hopefully someone at Tesla will see your post and save their business before it's too late!

If you're paying enough taxes to make a difference in that rich man buying a car, then you're rich enough to buy a car, too. The bottom half of earners pay *very* little tax.

His name is Bob Lutz. He either has no understanding of finance, or has an axe to grind. Considering his history of leadership in the big three, either is plausible.
One of our competitors trademarked the term "hypothesis". From now on, we will call them "boneheaded ideas".
