Thanks. I just ordered a set from tirechainsrus.com.

I have 2015 Model S 70 with 19" 245 45 R19 tires. Tesla used to sell Trak Sport chains. Now they sell König K45 chains for $420. I see Quick Trak car tire chains from Chains-R-Us for $340 that look exactly like Trak Sport. Does anyone know why Tesla changed suppliers? Anyone use Quick Trak...

The most common coolants like ethylene glycol or propylene glycol can burn, but their flash points are in excess of 200ºF, so would not likely catch fire from sparks. Does anyone know what the battery coolant temperature of a Tesla is? I suspect much less than 200ºF.

Has anyone, anywhere, documented a case of covid19 contracted by touching a surface?

Wow. High rates and arbitrary blackouts. PG&E really does suck. My nephew in Marin is shopping for rooftop PV and PowerWalls so he can beat the high rates and protect himself with backup power during blackouts.

You can't switch from tiered rates to time-of-use? Most TOU plans offer much lower middle of night rates, making home charging inexpensive. SCE charges $0.125/kWh from 10pm to 8am, PG&E may have similar rates.

Uninsured motorist is to cover damages you suffer in a collision when struck by someone without insurance.

I noted that, but the point was that there is not room for more and more as I inferred from "keep setting the bar higher and higher" in @puma's post.

Port of Los Angeles container terminal, on the other hand, is famous for long wait times.

Your statement is about half right. What comes out of tailpipes or exhaust stacks of ICE vehicles are chemicals that are precursors to photochemical smog, reacting in the presence of sunlight to produce ozone and other smog compounds.

I think you may have missed the point of Munro's presentation. Yes, the 4680 form factor may replace 2170 batteries with 1/5th as many 4680s, but they will still occupy about the same space because they are 5 times bigger. There won't be room to keep packing more and more batteries to keep...

Many states and local governments have laws making off-Grid living illegal.

I'll bet you are holding the connector close to the charge port door when you push the button. Try pointing the connector at the back window when you push the button. On my S, the antenna is in the back window, so when someone told me that, I started pointing at the window and it never fails...

That sounds likely. Here in SoCal, SCE has to approve the solar installation plan. They want to ensure that the homeowner is not installing generation capacity exceeding what the prior 12 months usage had been. We had to submit a request for deviation from that limit because there would be...

My nephew lives in Marin and wants to add solar panels and maybe PowerWall as backup when PG&E outages come. Please, all of you who have dealt with Tesla Energy in that area, let us know if the local branch does good and timely work. (I wouldn't recommend the branch near me to anyone.)...

So, your car just slid off a lonely, snowy road in to a ditch. It is -20F outside and 50 miles from the nearest town. Do you advocate trying to walk 50 miles, or just shut off the engine and wait?

"Heating and AC reduced" I wonder how much? Still enough to be survivable if stranded in -20C weather?

I wonder how much difference the Evannex window heat shields made? If it cut heat loss in half, then it might have been 3kW without them. Bjorn was heating probably twice the air volume in his Model X, open to the trunk for sleeping, as there would be in the cabin of a Model 3, so I would...

So, at 5.28 kW average and creeping at .53 km/h, might we assume that heating load consumed maybe 5 kw of that? If so, then it would take 14 hours to use 70 kWh at delta T of 50ºC. How big is Model 3 battery? At what SOC does the car shut down cabin heater to conserve battery?

Of course that assumes that you need the much to maintain interior temp. I have no data as to the rate of heat loss.

On another forum, one of the posters, who lives in Maine, opined that a Model 3 could be "life threatening" because of limited range compared to an ICE vehicle. Further on, he asserted that, if trapped in a heavy snowstorm, an ICE driver could last days, idling the car to keep the cabin heating...

I am not saying that anything will be changed. I don't know. But since the windshield is already laminated safety glass, that part would not be changed.

No, you showed us what laminated glass looks like. Double pane has an air gap between two panes and is used only in architectural applications

What are the ages of your household drivers? My neighbor had the same experience as she is moving to Florida and found rates quoted on a 5-year old Model S 70 being more than twice what their Toyota pickup would cost and twice what other Tesla owners in Tampa were paying. Turns out that they...

Windshields must be laminated. Most automotive side and rear windows are tempered glass, a very strong single layer that, when struck hard enough, or even just sharply at a corner, will break into thousands of little cubes of glass.

If you do, you will also get a smoother ride and longer tire life.

Please, people, for the nth time, Model 3 is not getting double pane glass. This is double pane glass: Model 3 will get laminated glass like this: Two pieces of glass with a polymer sandwich holding them together. Makes the glass shatter proof and greatly reduces sound transmission.

But the difference is that you work for a competent solar company.

If that were true, then your roof will collapse from all the screws holding down the sheathing. Honestly, I don't know where Tesla/Solar City finds such stupid people to work for them.

Almost all concrete tiles for the past 15 years, at least, have been nailed down at the top edge through pre-prepared holes. There used to be some tiles with lugs under the top edge that required battens to be nailed on first, then tiles "hung" on the battens, so only their weight and that of...

If it is well done, I recommend it. I opted for black alcantara in my S and have been happy with it for 5 years.

It must be an old car/truck to have a bumper that one could tie off to.

My mistake. I was thinking of OP's solar panels installation. With solar roof, just like any other roof, safety brackets would have to come off when they got ready to install the ridge tiles, at which point you have guys straddling the ridge to install ridge tiles. Of course, if Solar Roof...

Anchors are mounted at or near the ridge. Safety lines just short enough to prevent a clumsy worker from falling off the edge. It is also possible to mount anchors on the opposite eaves with safety lines running over the ridge for workers on the other side. OP's roof looks like 4:12 or maybe...

I understand the Tesla wouldn't use a 48V, but I wondered what applications would do?

That could work. Never saw one like that. 48VDC - where would a thing like that be used, I wonder?

What you are missing, I think, is any experience with squirrel cage blowers. The air path never comes close to the motor, whose long shaft has the blower wheel mounted to it.

"The air path can still be routed around the motor on a squirrel cage type." With about 60% reduction in air flow, perhaps. If their patent claims heat from blower motors, then they must be axial.

That might work for an in-line fan, but not a squirrel cage blower where the motor is outside the air path.

I get how the energy provided by the compressor can be used to provide heat, but how can the blower fan make heat?

Has anyone used MY heat pump in really cold weather? Anyone know what ambient temperature is too low for HP to work effectively? If there is a backup resistance heater, I'm not sure whether a user could even tell if HP is working.

I plan to make a wooden model of Cyber Truck for my little grandson, but haven't found many good pictures to work from. Does anyone have, or have links to, good, clear pics: Head-on Directly from rear Directly from above (come on drone geeks, help me out) Side view straight on (there are lots...

What? Harris is better than Denney's at KC? :)

Clearly early morning, but 40 stalls and you were one of only two cars charging?

16% less energy loss to internal resistance. That is where the 16% more range figure comes from.

It certainly won't be like that automated pack-swapping machinery they tested for Model S several years ago. :)

That was a classic. Fun to see it again. :)

Some high-mileage Teslas (over 200,000 miles) have received battery pack replacements, due to degradation. I wonder how degradation would be addressed with integrated cells concept? The gif that played during the presentation seemed to show a structural battery pack case being joined to front...
