I'm running the leaf motor to 15,000 rpm. If anyone wants to donate a rotor or whole motor from a leaf I will spin one to destruction so we can determine the true safe max RPM Be nice for a big website fundraiser and get a video up thats mandatory to like because its engineering porn, two of them w...

Anyone see the twitter storm from Musk when he cut off investors about M3 production? Apparently, those analysts were in fact quite bullish and supportive of Tesla. And Musk just hated being asked questions about M3 production. https://www.zerohedge.com/news/2018-05-04/bizarre-tweet-elon-musk-threa...

If I was going to build a custom Ev I would try to pick a complete drive unit for example a tesla rear motor and use that in the front of a small hatchback type car it's not going to break any records but make a nice run around, To interface the drive would be custom engine mounts and drive shafts ...

Why do we want to make 760hp for a family car ? Are they entering the pike peaks hill climb for a scenic holiday ? In the UK ford fiesta uses a 3 cylinder 1.0 litre ecoboost and this gets around 40 mpg with 120bhp plenty to get around to the local shops or travel a long distance. The kurb weight of...

I don't.

Basically, unless you have an OLD IXXAT cable, it won't work with that software anyway. I sell licenses and programmers at my site if you need one.

Is it possible to get that software anymore? I have an old cable.

Yeah thanks for the support guys. I need to give my patreons some love they deserve! But only send if you feel you really want to. As I have found my self full time self employed working very hard making great wages for the business. But as the page says parts and talent are welcome as well as this ...

It may be possible to mitigate some of the deleterious effects of such a horrendously heavy on vehicle handling, but nothing can be done to mitigate the more serious effect on vehicle energy consumption every time it accelerates. Well, some of the energy that is used to accelerate a heavy vehicle c...

A blanket statement saying that 200kwh in a single car battery is bad for the environment has no meaning as we don't know the production process of said future battery. If it's made at a solar power gigafactory than it might be 100% environmentaly friendly. It is bad because a 200kWh battery will w...

It is surprising that Telsa is moving to rare earth magnets, this is not good for mass production or green manufacturing. The only reason is to increase the range slightly, at a considerable cost and reduction in "green value" for a vehicle that is supposed to be green. The car being something that...

Small cells are like small chips. They only make sense until you know how to make big ones. It is a stopgap solution.

Tesla is burning week by week through investors money. What they depseratly need is that the show must go on. Part of that show is to claim, that they have some magical technological advantage. I see no "overall advantage" in small cylidnric cells now (when large pouch cells have become much cheape...

With the resulting fire hazard we cannot tolerate dead cells in a pack. Which is easier to remove? One of many thousands of cells welded deep in a massive pack, or one of a couple dozen in a bolted set? The future is not moving toward more parts in the system. Tesla is making do with what is cheapl...

Managing thousands of small cylindrical cells is a short term solution. None of the other carmakers seem to be interested in that. For the long haul much larger cells will take over and obsolete all the small cell systems. You have to decide what you want to own. If the technology is not stable, yo...

True, the gigafactory is their ace card at the moment. I think they will need to keep innovating or die - keep pushing the tech. Performance they have pretty much nailed, but next-gen battery would be a good one. AFAIK they are investing in people/research/startups on this so good luck to them and ...

Nissan also own and manage their cell and battery pack manufacturing plants..3 infact..Japan, UK, and USA. All Teslas cell technology and manufacturing is still dependent on Panasonic equipment and management in the Giga factory. Tesla have the pack design and assembly systems. Prismatic cells are ...

They also have a huge edge in the cost of battery manufacturing where as the others have to outsource adding a huge cost. True, the gigafactory is their ace card at the moment. I think they will need to keep innovating or die - keep pushing the tech. Performance they have pretty much nailed, but ne...

. . . .when most people say the word Tesla they think about a highly desirable fancy Electric car so Tesla got the branding nailed down for sure. Tesla should listen to you on that. But both the Model S and the Model 3 are efforts away from that into the relatively cheap, eventually. The branding t...

I see the biggest challenge to Tesla being the existing large ICE car manufacturers. Now the EV drivetrain is become mature and components & systems being offered by OEMs, it's becoming easier for them to nail together an effective EV and leverage their considerable existing manufacturing experienc...

The few people I have known who worked at Tesla say it is a crazy place to work, huge stress, impossible hours, unrealistic deadlines and the CEO terrorizes the staff. Turnover is large. Not good. Well I call everyone stupid who didnt know that before they have started there. If you want to make so...

I have read a stack of articles over time saying Elon/Tesla have been ignoring expert opinion that the core reason they have such poor production numbers is that they are trying to use robots in the manufacturing cycle where other car manufacturers don't (and have very much examined doing so but it...

Most companies don't show a profit for a while after starting a large expansion.

But as I said Tesla has shown a profit at least once after an expansion and it was after the model s launch.

Yeah this is such a dumb argument.

I meen how do you build factories and increase car and battery production without investing money?
