You rang?!! CrossClimate 2s in MN.

Sure. This is possible. 10 flexible 160w solar panels are probably the lightest option. You'll need probably 200-400ah(2-4 car battery sized) lifepo4 batteries, beefy solar charger and a 2kw inverter. All of that will set you back a few grand and will kind of be a pain to setup, but it should...

I don't login here much, but I've been around tmc and tesla since the beginning. I find that one of the best metrics for growth is volume of customer complaints. I'm very happy that the volume or the fervor regarding this hasn't changed over the years. Also, JRP3, keep up the good work...

I agree. While the recent price cuts have caused quite a bit of teeth gnashing on this board, I was really happy with the move. My biggest worry for Tesla organizationally was that they wouldn't be willing to disrupt themselves, but that hasn't turned out to be the case. Very difficult...

During the last cc, Elon was asked specifically about the price differential between ice and EV powertrains. This was his answer, " The - that said, in terms of initial cost of acquisition, I think it's probably - this is just off the top of my head, not a calculated number, probably on the...

I always thought this is such a super silly argument. Installing power outlets where people park is trivially easy and super cheap. Its super easy to legislate this problem away by requiring landlords make the upgrade. Additionally renters have choices in where they live, choices where they...

Or they could just choose option C and copy the successful stuff Tesla does and skip the rest. Listen, the point is that in a fully competitive market the terminal price for a product will approach it's costs. Whether that happens 10 years from now or in 6 months is irrelevant. Knowing...

Sorry, just saw this reply. I don't get what is so hilarious about my statement. Your comment reminds me of the scorn some mit aeronautical professor showed for Elon when he casually said that electric planes were certainly possible. It definitely comes from the same place. What is...

Continuing subsidies for inefficient and environmentally destructive activities isn't productive imo. Only 1% of the u.s. is involved in agriculture and only 10% are rural. Rural lifestyles exist in the u.s. today only because of huge welfare payments by the other 90%. This is nothing new...

Yeah, it was back in June. Also, current spot cobalt price is half what it was then and nickel is down about 25% so I think elons estimates are likely conservative. I think your pack level cost estimates are probably accurate. Imo we're at the point wrt Tesla where pack costs are likely...

Slinger rings work great, but can be noisy as hell. Modern window acs have eers approaching the best mini splits and variable flow central acs because of them.

I would argue that this is not only an inconsequential risk, but a symptom of Tesla's rapid expansion and a positive indicator for future success. Tesla's willingness to push out unfinished products(or rather mvp) and intentionally grow at a pace that stresses their distribution and support...

That's terrific. I missed this earlier. What a comically bad prediction from the esteemed professor. Revenue next year could easily be $30 billion just from debottlenecking Fremont and the new battery lines at Sparks. The model Y and Shanghai plants will likely double that again. Much...

While the rationale for the EPAs modifications to Cafe are nonsensical, I believe they are a boon to Tesla. The alternative regulatory regimes available to the states who wish to incent fuel economy involve variable tax and rebate structures to modify consumer behavior. Unlike CAFE, these...

I'm not sure where the blog got it's range numbers, but baic advertises a 318km NEDC range with a 48kwh battery for the ex360. I think they get their batteries from catl. Doesn't seem like it's anything revolutionary, but its still good to see more long range EVs produced.

You'd probably have to contact them directly for pricing of larger units. I don't see them on Amazon. Though they do advertise the 6kwh units for $3400 on Facebook. That's fob shenzhen so you'd have to factor shipping. My big point here was that they're making it possible to install a...

Miimura, I appreciate your reply. I'm pretty sure greater than 99% of the population would have no idea what you're talking about. And I'm pretty sure that 99% of the people that are interested in solar wouldn't even know what you're talking about. I'm not trying to be insulting, because...

That's some pretty nasty rent seeking and imo pretty obviously violates the dormant commerce clause. I'd probably just install them anyway and then litigate if necessary. I doubt it would come to that, but the intent of the ordinance isn't to prevent solar installation, just to make them so...

Ampster, Not really arguing about cost. The key innovation the Chinese did was turn all of this into an appliance. Everything that you(and I for that matter) cobbled together is now a box on wheels. It's simpler to setup than a tv, just as easy to buy and nearly as easy to install. Just...

This includes the Pv inverter. Essentially the equivalent of an outback radian or fronius symo - although at a reduced wattage. So, pretty close to Tesla on price per kwh once that is backed out. Pretty complete(and user friendly) solution for anything off grid. While it won't meet code...

Gsp, Thanks for posting this. This is an amazing little unit. Amazon also sells the 4kwh unit for $3200. With no tax and a 5% prime card discount that's an extremely good price. I dug up the manual. http://www.poweroak.solar/uploads/PS4020B-ESS-Manual.pdf The operating modes are...

Dude, they use cameras too. Right now Tesla has the best sensor suite available. If someone comes along with a cheap lidar I'm sure Tesla would be willing to integrate it for additional information, but it's not a necessary precondition to advance autonomous driving.

JB said there's not even going to be natgas piped into the gigafactory. All process heat is going to be via heat pump. Sounds pretty efficient to me. Edit: Just saw your later reply in thread. A modern heat pump can easily have a COP of 4. Even compared to solar heat directly. A heat...

I thought the point of the residential PowerWall was that it heads off the attacks on net-metering. It seems like a PowerWall or two would allow a consumer to completely divorce its solar system from having to back feed the grid(not necessarily go grid free). In states like Hawaii and...

Itsnotaboutthemoney is right. Tesla uses nca chemistry which is 9WT% co. Just goes to show how misinformed even so called experts are. http://articles.sae.org/11923/

I'm not sure exactly how to respond to this. Did you try plugging in some numbers? Do you disagree with the equation? The point I'm trying to make is that your(and Robert's and the utilities) arguments regarding net-metering are specious in a literal sense. They are nominally true in that...

Perhaps a little math would help with this. As you say residential pricing in the U.S. typically consists of two components that aren't billed separately - the demand and the consumption charge. Your argument is that net-metering doesn't scale, because this demand component is fixed and would...

Saying something is a fact doesn't make it a fact. Its your judgment. With regard to the original article, the SREC2 program has an estimated cost increase of 500-933 million over the total life of the program(until 2045). That's less than was quoted in your piece of yellow journalism. The...

This argument as espoused by Robert and others isn't true. The current grid already has to deal with intermittent, variable and uncontrollable demand. Its not at all true that net metering increases this variance. In fact looking at germany's generation from this link(admittedly old data...

Isn't this the range with aero wheels and lrr tires? Seems like we need to cut the CNBC research guys some slack. I hear a 265 mile range on tmc way too often. That was so a year ago.

I think the gen3 has a pretty easy roadmap. I assume top of the line car has 66Kwh pack. 10% efficiency improvements in drivetrain and CdA. 6% from wheels and tires. That gives a range roughly equivalent to the S85 using S60 efficiency as a baseline. Assuming battery improvements can yield...

Doing some back of the napkin math I figure Tesla's demand for batteries right now is nearly the wh equivalent of 1/4 the worldwide supply used in cell phones(78KWh*25000/(5wh per phone)/1.7billion phones sold. I'm not surprised that Panasonic is running into supply constraints with Tesla...

That was a good review. Thanks for posting. I think that Google Glass really needs to be in the toolkit for auto journalists. Worked really well.

What is the warranty cost per vehicle currently? How is it trending compared to earlier Model S and vs lifetime Roadster costs?

This article is FUD. Regulated utilities negotiate their capex for line extensions/upgrades/rebuild every couple of years. Their cash-flow is predetermined. Fitch is basically complaining that a large increase in net metering could eventually cause a power surplus in localized areas and a...

However that trade is not frictionless. Our military budget for 2014 is 600 billion dollars. Its not a simple guns vs butter analogy, but the large trade deficit(due almost entirely to energy) is a drag on potential GDP growth. While I agree that a multiplier effect exists in trade whether...

According to the eia link you posted the u.s. imported 36.4% of its oil this year. That percentage has been dropping by about 5% per year for the last several years. Of course the elimination of imports implies energy security and a profound change in foreign policy. This is why Cheney and...

I really shouldn't feed the troll, but your statement regarding range is categorically not true. It is trivial to make a short-range bev, but much much more difficult to make a long range one. In fact most automotive experts thought the model S range was impossible prior to Tesla actually...

I agree. Still, I worry that the large automotive companies really don't want electric cars to succeed and their current efforts are really more comic foils to showcase electric car limitations rather than honestly pushing the envelope and trying to make viable EVs that can succeed on their...

Except the ridiculous specs they first quoted are starting to come back to earth. Now back to 150Kw total with two motors and 0-60 in 5.9 seconds. Must have had trouble with the flux capacitor much like Fisker, Chrysler Envi and Lightning Car Co to name just a few.

Panasonic has new 3.1ah 18650s in production now. I wonder if Tesla is contemplating using these even though the new nnp cells have a different voltage range than standard li-co cells. Swapping the existing cells in the roadster with these would presumably mean greater than 300 mile range...

Imho Fisker is all hat and no cattle. Although I agree that Tesla probably missed an opportunity.

I don't think having a hand wound motor would increase the current rating like the article mentioned. More turns means more flux for the same amount of current and higher power for a given voltage and speed, but the current limit is more a function of the PEMs IGBTs and heat dissipation of the...

I like these type of reviews. While certainly not unvarnished praise, it compares the roadster to other supercars in a no compromise sort of way. This is the next step for EV adoption where they can be compared to ICE cars directly without apologizing for the short-comings of BEVs. Similarly...

That being said, I BBHighway's reply eloquently put paid to this commonly raised criticism - even if it was raised by a bot.

They are the contract manufacturers for the inverter and parts of the abms I think. Which comes out to around $10k per vfd. Hopefully they can get this a bit lower(maybe $5K) when they ramp up production for the S though the price they paid is reasonable.

I've been thinking about something similar. I don't like adjusting controls on my center console. I've got to lean forward and take my eyes off the road. I really like having steering wheel buttons. However, I was thinking in the car today, that it would be really nice to replace those...

Very interesting presentation. Lots of new details in slides. I was particularly interested in the powertrain and chassis schematic slides(about 18 minutes in I think). 25% improvement in battery mass efficiency? Does that mean they are targeting roughly 145wh/kg all in? The new skateboard...

The single speed is the way to go certainly. Just look at the drivetrain losses the camaro suffers relative to the roadster. It's torque at peak hp in first gear should be about twenty percent higher than the roadster's given it's larger powerplant, but it never exceeds it. That's entirely...
