The one that made me laugh was the suggestion of replacing Mach (though really even then NeXT was more than *just Mach, but w/e) with the NT kernel.

Can you imagine what MacOS and iOS would look like if they were built on NT? Not so much because they are technically incompatible, but more for the political implications of MacOS being married to the heart of Windows.
You could always buy a regular certificate from a vendor such as Identrust or Verisign.

I must say Elon is a brilliant engineer but not the best of orators.
That's the price to the installer. They'll mark it up, and then you have the necessary accessories and installation.

This looks more like a $6,000-$8,000 item once it's all up and running. Gonna have to run some math here to figure out the ROI.

According to the EPA [1], an average home consumed 12,069kWh in 2012. So assuming a constant load, a 10kWh battery would power about 7.5 hours of usage.

Can someone please share what a single family home can do with 10kWh?

If I pay for this do I have to plug this thing into my own electrical grid to keep charging it?
I love the movie "marmaduke"
How does that go away? Most internet advertising/surveillance is performed by the actor with whom you're directly communicating, I think....
Just a plug because I built it, but branch.io gives this service away for free. We open all the 'black-box' fingerprinting parameters (like match duration) for you to tune as well.
Grooveshark changed my life.
Proof, if anyone still needs it, that Tesla is a battery company that builds cars, not a car company that builds batteries.
> Throwing away data like that is unforgivable for a service.

Did you consider that immediate deletion of the data might have been part of the settlement agreement, and that there was (for Grooveshark or their owners) therefor not much of a choice to do otherwise?

0. Tesla will open source its patents for the Gigafactory.

1. Elon thinks all the world's energy needs can be served with 2 billion Tesla GW powepacks.

2. Elon: "This is something we can do, need to do and should do."

It's over.
What organization would you consider more trustworthy?
No. Consider that DNS request/responses are simple, cleartext UDP packets. There's DNSSEC of course but nobody uses it (and also most security experts don't like it).
So if I'm reading this right - if I bought a Powerwall from Tesla and hooked it up to some solar panels, my power bill would DRASTICALLY decrease?
You need 20, not 12, don't you? 6V*20 = 120V

edit: the Powerwall runs at 350-450V, 5 amps nominal. Guess it depends on the inverter you use.
I'd guess it's simply legal hygiene to defend against a phoenix.
Somebody just stated that technically this would feed the average home consumption of energy for about 8 hours. Why is this a good deal, even if it were 24 hours?
I'm a person who actually deploys .net apps to internal IIS QA servers. If I want them to use HTTPS, I have to configure it. I don't know anything about my own CA certificates. I'm not saying it couldn't happen, but it's certainly easier to suggest just not using firefox if something isn't working.
Musk's delivery style is so refreshing compared to the Steve Jobs clones on every stage. He's knowledgeable, charming, funny. Great stuff.
Which specific EFF policies/goals are you opposed to?
The map graphic at the beginning was pretty powerful (please excuse pun)
I'm intrigued at the backup possibilities, because we live in a forested area of the northeast where outages are common during storms. But at 3Kw a single unit isn't large enough to power our entire home, and I didn't see a figure for how long it can operate at peak load. If I need two then we're getting closer to the cost of a natural gas fired generator. This analysis, of course, is completely ignoring the environmental benefits.
Yes, you probably should assume it is. The good news is that it's easily detectable. Your browser should refuse to connect to the proxy-spoofed gmail because it likely hasn't received the visited-corporation's local-spoofing-is-ok cert.

You might be encouraged by the local team -- "don't worry, just do this so you can access gmail again." It's too bad that this activity trains people to think updating your certificate store (based on directions given to you by some site in your web browser) is something that you should do to get past an error message.

2 billion battery packs, and how many solar panels to feed them ? Did I miss the number ?
$3,500. That's crazy good for your average household, on par with natural gas backup generators with half the logistics. I might just be ordering sooner rather than later given some of the grid instabilities in my area over the past year, and through the mid-term in preparation for a solar switch here in Chicago.

While Elon might not be the best orator, you can easily derive his authenticity and belief in the product by virtue of his delivery. You can't do that with accuracy in the canned and carefully rehearsed.
As an investor, I'll take this anyday.
I am not really happy with either Git's or Mercurial's solution.

Git's branches introduce too much fragility in the system for end user consumption (because branches are responsible for both naming and keeping commits alive) and do not allow you to describe sets of commits (nor is there an alternative feature for that), Mercurial's branches are too permanent in that they cannot even be renamed (well, there's an extension for that, but that's not without issues). Mercurial bookmarks still do not allow you to label sets of commits, but at least aren't responsible for the liveness of a commit.

In practice, I like both Fossil's and Bazaar's model better.
So, when does Microsoft release their Genetic Algorithm / Z3 based Fuzzer called 'Morden'? It's what I want at least.
Specifically I'm thinking about current procedures to verify domains - either it's through your registrar (in which case you're golden), or an alternative like adding a specific key to a TXT record, or uploading a particular file to the domain root.
I would agree. He's not very compelling.
I find it endearing. Makes me trust him more and not make him seem like a shyster selling snake oil.
I've watched maybe 7 videos about him. Musk is too eager to throw employees under the bus.

It is this reason alone why I'd never buy a tesla.
How is good software designed and where does Docker fall into this?
Your utility company is going to want to charge you a fee (or take a cut of what you sell to the grid) for not buying any electricity from them, so that they can maintain the power lines and substations to your home.
I was thinking the same as I watched it. I was wondering if there were some technical issues to explain the slow start of his speaking part and if he might have been frazzled from whatever happened behind the scenes.
The solar panel count was not mentioned. Though he did show the blue square and the red dot for the USA.
I fail to see how my list of song titles infringes copyright and requires immediate deletion.
Any news on international orders? I live in Australia, and would love to integrate this as a full off-grid solution.
Yeah this doesn't factor in Solar Panel Costs and the cost to install this power pack.
This would all make more sense if they made solar panels to go with the powerpack. Otherwise, it's just a huge battery.
The voltage is irrelevant. You can run an inverting 120VAC power supply from one battery, or a hundred, as long as it supports the right voltage range. Yes, putting 20 6V batteries in series would give you 120VDC, but that's not particularly useful.

What matters is the energy capacity, which is measured in kWh.
10kWh and the details will be forthcoming I am sure.
A solar array would expedite charging, but I believe they intend to monitor energy supply rates and charge based off that as well. eg. When rates dip, it charges at a higher rate.
It's because all CAs are able to sign certs for all domains. Browsers simply do not trust your average domain registrar enough to give them power over all domains.

Now you might say don't trust the registrar, trust the people who run the .com (or whatever) TLD. That's getting close to what DNSSEC does, which some people say is better. But CAs weren't designed for this like DNSSEC. With the way CAs work, we would have to give the runners of .com power over all domains, which some people might not think is so bad. But it would also mean we would have to give the owners of .sucks power over all domains as well, which most people would be against.

Pretty cool that it's "Gigafactory 1"

And they're viewing it as another product.
I read this in 1997. A lot of these seemed like terrible ideas even at the time.
I thought he said the wall unit was 10 kwh?

EDIT: Unless you mean it's limited to a 3 kw power draw - looks like it's 3.3 peak and 2 continuous.
Sure, but the same would be true if you bought solar panels and lead-acid batteries, which are cheaper (but less compact). Or if you bought just the solar panels, and sold the excess power back to the grid (assuming your utility provider allows that).
actually, its not really "safe behind a firewall"

what if im inside the network i tell your monitoring that everythings ok while i break stuff?
I have four rack-mount uninterruptible power supplies that provide battery backup to my workstations and servers in my house. My curiosity here is whether this Tesla battery pack will obviate those UPSs, providing automatic and immediate in-line switching to battery whenever there is an interruption.

That alone would be compelling at this price.

Edit: Incidentally, when I submit the reservation form, there is no confirmation.
I love the attitude some of speakers in the video show towards people with technical understanding. I guess when you are incompetent you always need to test people to see if they are lying.
The 12 number comes from energy storage capacity. Voltage conversion and DC to AC is handled by your inverter/charger which is a separate item.
Woah! What!?

That is insane to me. Hermain Cain did his undergraduate in math and his masters in CS... and from good schools, no less.

I wish I would have known this in 2012, I wonder how it would have made me feel about him, when watching debates. I don't remember much about my opinion of him, but I can definitely say it never crossed my mind that he would have this background.
SolarCity is another startup that Elon chairs... The idea is that the batteries and the energy generation process/supplier don't have to be the same.
The first paragraph resonated with me a little bit. When I was younger (14-16) I'd always try to type as correctly and "seriously" as possible. I literally thought everyone who didn't do the same was just stupid. My IMing style is pretty much the opposite nowadays. And as much as one hates being biased I have to admit I still judge people on their typing style a bit. It's pretty hard to gauge one's tone/feeling/attitude without having all the hahas, emoticons, smileys, redundant words etc. Do they not like me? Are they trying to be rude? Are they being creepy? Are they just not much of an internet chatter? Is that just an aspie-like trait?
Doesn't include inverter or installer markup and can only provide 2kW output.

It will get expensive by the time you actually have all the bits you need inside your house.

How is this better than deep-cycle batteries (with 20+ year lives) again? Why does it need to be slimline?
Today is a big deal.

Open sourcing the patents to build fully solar-powered electrical grids around the will be a paradigm shift in the power structures of the world. I expect from today onward there will be a full-scale attack from those who stand to lose because of the reduced dependency on oil.

First they ignore you.

Then they laugh at you.

Then they fight you. <--- WE ARE HERE

Then you win.
Isn't this basically extortion then?
It's really absurd that Mr. Conley prefaces his statement by saying "I'm probably the least technically proficient guy here" and then goes on to make the moon landing analogy.

Can you recommend any resources for someone that wants to hike the PCT? I'd like to do it in the next couple years, but the logistics have intimidated me. I've hiked the JMT twice, and doing it again this year. I'm not really even sure where to start with doing something like the PCT.
A lot of the stuff Tesla is saying about this is quite weird. (In the press kit and in Musk's live stream.) For example, the first sentence of the press kit:

> The world currently consumes 20 trillion kWh of energy annually. Enough energy to [...] supply energy to a nuclear power plant for 2,300 years.

Am I missing something, or is that an entirely bizarre comparison to make? What does this even mean?
The Python library that makes benchmarking easy and fun
3kW is the power, 10kWh is the energy. Your 10kWh battery would discharge in 3h20min at peak power.

Or, you could listen to music on your 250W sound system for 40h.
And the marketing.
So. COOL! The coolest part...that Tesla realizes that the goal it wants to accomplish can not be done alone. They need companies and people around the world. All patents are open and free for anybody to use and all technology is open source. That is amazing. That's how change happens!
>It's also refreshing to see someone in government recognize that the solution to unfavorable speech isn't censorship, but more speech.

Read between the lines. He's not saying that. He's saying that the solution to unfavorable speech is to insist on "accurate speech". I think when he says "more speech" he means "more of our speech" (government sponsored new media initiatives, I guess - paying people to post approved facts to facebook perhaps?).

Their messaging on this is consistent. They don't want a plurality of opinion if it means that sometimes "lies they don't like will be told". They will "insist on accuracy".

For you, of course. There is no mechanism that I know of that holds the government to the same standard.

The practical upshot of this is that freedom of speech can be quashed with libel laws and a judiciary that could hardly be described as "independent of the government". Unless you can prove beyond a shadow of a doubt that everything you say is true, they can slam you with fines and possibly jail time for statements that you made that are either untrue, can't be proved, or they can describe as 'racially inflammatory/insensitive to religion'.

They can pick and choose, too. Say 99 things that really needed to be said, and repeated one rumor that wasn't true? If you have an audience and they don't like you or want to make an example of you, They will nail you. That's why there's a strong culture of "STFU and keep your head down if you know what's best for you".

This is part of the story of how political opposition in Singapore has been divided and conquered and kept at bay (there's a lot more detail in the wikileaks cables about Singapore, which is worth a read). I suspect that if they had a first amendment, the PAP would have started losing elections a while back.

Who knows, though. Maybe they won't find a solution to the 'new media problem' and the opposition will manage to leverage it to win an election in the years to come.
Does anyone know if there is a PAC aligned around technology-savy candidates? Seems like something the EFF should be involved in.
can someone explain how the open sourcing he mentions will benefit Tesla? typically open sourcing is only best when you are a platform as a service. I'm not seeing that - what am I missing?

The sheer per-capita revenue of Valve staggers the mind.

Playing the margins in my home would probably save $25/mo against a $100/mo charge, I'm spitballing.

Our local utility here in Chicago, ComEd, is starting to roll out to the population what flux in energy usage actually means on a granular basis (hourly, daily, monthly, seasonally) while offering incentives to change their consumption patterns.
I might spend $480 on electricity per year. I can't see this thing having an ROI within its lifespan. I also don't have solar panels, and have a very reliable power grid. Any reason I should consider buying one?
Yep. I just use the monospaced variant. Unless we radically rework editors and terminals, proportionally spaced type seems unworkable.

"so you don't need a battery room" - Elon Musk
I'm going to install a 9kW solar grid on my roof in the next couple of months - capital cost is ~$40K USD. Without the Power Wall, I'd be selling power back to the utility at around $0.10 / kWh, and buying it back at $0.09 / kWh in the evenings. The Power Wall will also let me endure grid outages as well (you can't run your house on your solar panels directly).

I'm really curious about what the end-user cost is going to be for one of these batteries, after distributor markup and utility company rebates. Would be interesting to see if it pays for itself over the 10 year lifespan of the batteries.

I just reserved one.
I was just discussing F# with my coworkers today. I feel like it doesn't get much attention because neither the OO or the FP camps want to own it. It's too different for OO people, and FP people won't find it pure enough. Is that correct, or are my observations and inferences way off?
Living in the north that -4 degree F lower operating temp limit makes me sad. Sure you could put it in a heated garage - but I bet this explains why no one up here owns a Tesla vehicle yet.
According to http://www.eia.gov/tools/faqs/faq.cfm?id=97&t=3 the average U.S. home uses 10,908 kWh/year, so this would be enough to keep the home running at full load for about 8.4 hours. Not bad.

If you took steps to reduce consumption (avoiding using heavy demand appliances like electric ovens, etc.) it would last a lot longer. With a little care, you could probably run for a couple of days on one of these, particularly if you had LED lights, etc.
Not really. Intel pays people to write drivers for linux.

OpenBSD is basically entirely volunteers.
Would the benefits of solar power being extended into the evening be worth it? Back of the envelope calculations:

If you can run on solar all night there's potential savings. Assume 10kWh costs $1. If you have a surplus of solar during the day and you fully deplete at night, you theoretically save $365/year. Break even is at 10 years, which coincides with the warranty.
He was the same at the Dragon 2 launch. I get the impression that he doesn't rehearse for these events much, probably because he's probably got much more important things to work on.
As someone who avoided the startuposphere so that I could focus on climate change activism and pricing carbon, seeing Elon Musk implore the world to avoid winning a Darwin Award was so incredibly rewarding and validating.

He will most certainly be fought tooth and nail, but he has allies.
10kWh of deep-cycle batteries aren't that large. It's not like people in apartments are going to be using this product.
The maximum temperature will be an issue here in Australia. In a typical place where it will be mounted, i.e. the garage, the temperatures will readily get over 40, close to 50 during summer.

I could see this also being a problem in places like Nevada and Arizona in the USA.
There's plenty of privacy and freedom on the internet... otherwise the internet would not have existed this long the way it has. More security is always better but let's please stop with hyperbole.

I guess the question is how long the powerwall is expected to last, and how novel the linking of them is (I have no idea). Additionally, we can hope that once the gigafactory is up and running, or version 2 of it is, that prices drop.

Really, I think the big advancement here is attractive packaging of the product and experience, a la Apple.
This was offered to SolarCity customers in late 2014, I see that the image here http://www.solarcity.com/residential/backup-power-supply now reflects Tesla branding.
> 7kWh or 10kWh

Can anyone speak to what that could power? Could I run a load of laundry with it? How about dry it afterwards? Here in Italy people mostly take advantage of "solar power" by hanging clothes to dry, but just to get an idea of what the battery could run.
> I expect from today onward there will be a full-scale attack from those who stand to lose because of the reduced dependency on oil.

Maybe. But remember we don't have the technology yet to completely move away from fossil fuels. The biggest issue I know of is making Airplanes electric which so far has not proven really feasible (as far as I can find anyway). This solves a huge chunk of issues but there are still plenty more before we can claim we have the technology to completely transition.

I'm excited for the possibility however.
Is it really worth it if it really takes 10 years to break even (and that's the lifespan as you mentioned)? That's like giving someone a 10 year 0% interest loan.

Maybe you're better off buying a bunch of Tesla stock with that money if you think they'll stick around that long.
