I used to work in the next room over from Webb when it was in the cleanroom at Ball Aerospace, circa 2009. I remember back then the launch date was supposed to be 2015, which seemed like forever away. But the instrumentation was so advanced, the science that would come out of this thing would be...

I asked my sister about this. She works for CNET's parent company, and manages new advertisers and sponsor campaigns for their multiple media outlets. I sent her the side by side comparison of the two different articles and asked if she see's the problem. I also asked if Lexus is a paid sponsor...

Perhaps Elon will just ignore the Ford fiasco and keep on keeping on. OR, perhaps he will respond by RELEASING THE PRODUCTION SPECS, PRODUCTION DATE, AND PRICING for the CYBERTRUCK on the same day Ford starts delivering vehicles. 4/26. That would be a great response...

Sidenote: My mother just bought a new vehicle after getting fed up with maintenance issues on her current ICE. Before she went to the ICE dealership to trade in and buy a new one, I begged her to just test drive a Model Y. She refused to do it. No interest in even trying it out! Isn't that crazy?

This article (and the report it's based on) may be super important when it comes to the traditional OEM's who have spent so much time creating an ICE culture that is 'superior' to EV's. Their customers have no idea that EV's are objectively better vehicles than ICE. And that's their own fault...

<Begin rant> Another bullshit anti-electric posture from the Sledding community. This author is absolutely clueless. And he's completely wrong about his central point that all sleds are going to be electric someday. The snowmobile scene will never become all electric. It simply isn't an option...

You may be right! I hope so. I think the counter arguments would be: - Energy storage based on ion-movement type batteries depends on the number of ions available, and thus depends directly on available mass. - For a true step change, we need to get beyond mass-dependent battery types a find...

It seems like the way Mercedes achieved such high range was to cut back drastically on mass and drag. That's all fine and good, but it shows that their battery tech is not driving the gains. In fact, I would argue that in general, battery technology is not going to improve drastically more than...

It's a gorgeous and great concept. But to be clear these are all renderings, right? Mercedes hasn't actually built this thing, they just imagined it. I'm really happy to see the emphasis on reducing the drag coefficient. EV's need to be about efficiency.

I was in that same Tesla store in August. They had a Model Y in the store, with several people playing around on / inside of it. We test drove a Y that day. Blew my mind.

Most switches have POE ports that turn off/on based on the device you plug in. My guess is that your switch is not properly detecting that a POE device is plugged in, and thus not supplying POE. Something about the signaling is changing when you connect through the (unpowered) POE injectors...

Serious question here: What are the actual chances of Rivian still existing 5 or 10 years from now? Their plan is to build a new plant in Georgia, construction starting this summer. Maybe Amazon and Ford are willing to bankroll this, but then what? By 2025 when Rivian's output is finally...

Yeah, Tanks. Currently down to $99.30. Down 14% today. Down 7% from IPO. They're burning $1.2 billion per quarter. And have built about 700 vehicles. Yet they're valued 25% higher than ford. If that is a reasonable valuation, then TSLA stock should probably be around $50,000/share right now...

Interesting news on the Rivian front: (source) Rivian stock tanks after EV maker sees production constraints hindering sales Last Updated: Dec. 16, 2021 at 6:10 p.m. ETFirst Published: Dec. 16, 2021 at 4:32 p.m. ET By Claudia Assis 0 Rivian Automotive Inc. stock tanked late Thursday as the...

Hilarious. Ridiculous. Jeep clearly doesn't care about aerodynamics, which means they don't care about efficiency. And that Honda looks like a Cybertruck-Lincoln lovechild.

Man I hate to join in on the cynicism, but reading these plans and the production numbers has me shaking my head. They're just so far behind Tesla. I applaud Ford for making this investment, but it all just seems wayyyyy late. By the time these factories come online in 2025, and produce 160,000...

So what exactly IS an EV tire? They're lighter weight? ....ok. That's important to increase range. Less rolling resistance? ...ok, also important for range. But how will these tires perform in adverse conditions? Is decreased weight and rolling resistance a trade off that causes worse traction...

This is going to be hugely important for the US, and world climate in general. Props to Straubel for tapping into this market ahead of time. I'm sure someone on this forum knows the answer to this: is Tesla recycling used batteries to mine them for raw materials for its 4680 plant? Do they even...
