Three-phase electric power - Wikipedia Generally, 3-phase power is the standard power generated at the power plant and distributed through the system and its transformers except for non-business customers. Once you know what to look for, it is mildly entertaining to analyze your local power...

TESLA MFG NEEDS SOME RETIRED MERCEDES MECHANICS WHO ARE USED TO DOING RESTORATIONS. They are masters of knowing what will work and what will not, and knowing how work quickly and efficiently, and understanding unit repair. IMHO Tesla could have been well served with more vertical integration in...

A car guru once told me that customers come and go, but enemies accumulate. Why is Elon trying to make enemies? He will never be able to reverse the enemies he has made from this debacle.

If the steering wheel is off center and the car pulls, Experience with pre 1990 german cars indicates the car has been bent or adjusted without centering the steering wheel. A reasonable repair would be to check for damage and wear or looseness then align the car front and rear. Try this first...

There is an electric suspension that will perfectly control the suspension, jump over obstructions, and generate electricity. I guess it will jump a pot hole. REMARKABLE!

Uneven cupping and wear can be caused by a loose belt in the tire tread. Often bad front tires will cause shimmy. I once worked on a car that had all 4 tires bad, so if you are having a bad day it may need more than one.

Tesla should be able to get any amount of performance they want out of a mule by adding battery packs and drive motors. The MFG price on that stuff should be pretty small. I wonder if they have considered a low profile model trailer and tractor for dense cargo, looks like they could cut frontal...

Apparently they want to put new developments into trial operation as soon as they are useable.There appears to be quite a few ideas in the queue. Big differences with a subway, everyone has to stop for anyone to get on or off, and subways do not go door to door like a POV in a tunnel. Musk’s...

For $1500 you should be able to get your lawyer to install it, and throw in the permit for free!

Metallic and pearlescent finishes are expensive to paint and expensive to repair. Tesla needs to add plain white and perhaps other colors at zero cost in the interest of customer sat! Let us spend the extra 2Gs on something else!

Anyone know how big a deal it is to upgrade to 150kW SC? Add-on or complete replacement?

Last I heard, Trump was going mano a mano with Pres/ Gen Secty CCP Xi. Trump wants end of IP theft, Belt Road Policy, and S. China Sea acquisitions or have trade war! Trump was shocked by China’s reneging on already negotiated agreed policies. China wants to continue its world domination schemes...

I thought the car would map trips - they keep track pf Superchargers...

Build a plant in UK if they do a sufficient BREXIT. Elon can build the batteries in NV and ship them if desired, they are compact and should cost much less than a car to ship. Norway is a big buyer of Teslas. Brazil is another possibility if the new conservative Bolsonaro government does well.

Cities are not germane, the CCP is all except for the Chinese people.

The cloud seems much more than water vapor!

The cat is out of the bag for China, as long as the CCP is in charge, China is history for companies with IP to shield. China already has ten electric car companies, they just want Elon’s battery and mfg tech. IMHO. There may soon be a revolution there too! Hong Kong is resisting China’s...

Do you have any detail on exactly what parts failed in the rear drive unit? Does it include the motor or just the gears?

Aerodynamic drag is proportional to the product of the drag coefficient times the frontal area. there are other variables like speed and other factors.

Try drawing a free body diagram of that to get the answers. No reason you cannot have drive at any or all wheels.

May need bigger bearings due to fatigue.

Lift (+/-) increases drag.

Multiple trailers should be possible to use with autonomous controls. Imagine parallel parking with two or three trailers. Cutting the frontal area in half should come near cutting the high speed drag in half.

Why the mystery? All you have to do is reverse the ball joint manufacturing process and see where it failed. Ancient Jaguars used to have ball joint repair kits containing a ball stud, two ball seats, a few shims, and a rubber boot to keep the grease in and the weather out. If someone put it...

Ten miles is ten miles. The change may change charge rate which might be worth something depending on the lengths of your trips.

If my scenario is true, then running your suspension high or low for a time would distribute the lubricant before returning to the recommended level for high acceleration. Again this just speculation. Elon may be eliminating the off center run-angle to minimize friction. Elon needs to hire some...

RE DREADED SHUDDER: Have never been under a Tesla, but universal joints should run at an angle sufficient to distribute the lubricant and equalize the wear. Once there is sufficient wear in the joint that is a sufficient size to catch the ball or needle bearing, there will be a kick that can...

Or you could build in NY, the state would like them for taxis and the cars could be an entrée for Boring Co. tunnels and taxis around Hudson, NYC, Long Island and to replace ailing subways, tunnels, bypass traffic jams. Over $10B is planned, may go to double that with conventional transit...

Why not build in NV? CA is going nuts, what will they do next?! And how is NV work requirement going? Trucking cars to CA will require lots of truck miles to work out truck bugs and establish driving and mfg dependability record while not in public hands.

Elon might consider building some rooms or even bunks in the vacant spaces and floors of GF1, trailers outside might get too hot.

Forty years ago Mercedes used to have many parts that were rebuildable. Perhaps that is the trick for the door handles. You could make the parts specific to the car, the chrome handle and the frame and latch, then have the electronics in a separate module. Electronic modules could be universal...

The factory looks like it is in a flood plain. Cannot be sure.

The Wright brothers’ first flight went 120 feet, the last that day went 850 feet. Musk’s Spacex is doing well, as are his other businesses. New ideas take time to develop. Since Musk proposes private financing in exchange for fares, the price cannot be the problem. The Dem VA governor is the...

I watched a video of the shop floor and Elon needs to get a few retired shop owners to oversee the workers and teach them how to work fast and carefully. They would be good for parts QC too.

Does Tesla do any development work including the customer??? Some say it is key to success.

Perhaps Tesla will have better ground clearance and tires with the new pickup truck line. Time to start ragging him in the winter when people can get stuck in snow and ice. Maybe Norway is a target development country. What do they do there in the snow? When are we going to see an...

—— Before Mercedes’ escapade with Chrysler, they used to support the resale values of their cars by assuring the supply of parts and repair data to independent repair shops. Parts were also available from good german aftermarket mfgs. This is now less the case. Tesla’s battery policy is in...

Drag is calculated by multiplying frontal area by drag coefficient. So the drag and fuel consumption should be proportional to the relative drag coefficients and energy consumption of each.

You need an audible alarm, of course, but a phone-in to your cell and the police with a video of the perp in action and a traffic sensor that tells the direction in which he escaped along with acessessing his credit card microchip would help.

If used Teslas are under priced, then buy one! Used car prices are often determined by the local prices of repair and insurance among other things.

The gear teeth have to wear in. Sounds like the metal was very fine, perhaps something like metallic paint? I would perhaps notify Tesla then keep an eye on it, ask about normal findings, take a photo. Is there a magnet on the fill plug? That would allow checks without draining.

What does “certified” mean in this context? Sounds like fraudulent use of the word. Try to get Elon on the phone. This sort of no-service counteracts huge goodwill worth million$. And this what unsupervised contractors do without strong controls. Why not suggest having company concierges to help...

SpaceX can test roughly 300 missions for the price of one Shuttle mission. ($450M/$1.5M)=300

Elon needs to have some long talks with the President. I can understand caution on NASA’s part. 1) Nobody wants to see anyone die. 2) The NASA swamp does not want to see SpaceX succeed where they have not only failed, but ran the Shuttle since 1981 with rising casts, not falling ones (...

Battery charging braking will stop if down hill energy exceeds battery capacity, much more load on brakes!

How different is racing from towing a trailer on a long curvy downgrade regarding brake load?

My second hand experience with antique Porsche 911 autocross cars is that drilled rotors cause cooler brakes, longer pad life, better brake feel, less dust accumulation. High performance German cars have had drilled rotors for circa 2 decades, so I would not expect much problem with them despite...

Brake reservoirs empty out as brake pad wear causes caliper pistons to extend from their bore and a volume equal that of the extended piston is required to match that of the extended pistons. A fluid level sensor has been used to indicate pad wear, but the usual response to low fluid level is to...
