But all-electric truck fleets...not for long-haul.

Plenty of people are enamored of that whole mystique, but he's the first one I'm come across who seems to have serious issues with rural America.
What the heck happened?

Left to the city because that's where things happen, education is rewarded and pay is doubled. It's a great place to be in when you're young and full of energy, but I look forward to returning to my home state for retirement, it's a good place to go when you're ready to pass on. Cheap land, slow lifestyle, perfect at an old age, I'm fine with living 20 years in the past by then.
It's tough love and allot of frustration for the young ones that have trouble finding good modern jobs. Unless they venture outside those rural states as well. Seeing your home state continue to be in such a limbo firsthand, and the people being so apathetic about it, is always disheartening.
Glorious wrote:Cool story bro,
what does it have to do with EVs?
ludi wrote:Perhaps, but that largely depends on your battery utilization for periods of heavy loads. If you need to pull from batteries to climb a hill, that's no bueno. You'll probably need that diesel generator to provide current directly to motors, and the output has to match what's available today. There are two additional concerns, though. First, what does the weight-to-power look like? Battery packs are heavy already, but the capacity needed even for a hybrid could be substantial. Second, battery fires are a big deal if things go wrong in passenger vehicles. These packs could be considerably larger, AND you have a tank of diesel fuel for the generator. Even without a transmission, you're adding new challenges and risks.I could see a pretty good use case for diesel-electric hybrid trucks where the diesel-electric drivetrain eliminates the complex and expensive transmission as is already done on train locomotives.

Probably not for local work, either. Tesla's best chargers claim ~30 minutes to 90% charge? Something like that? But that's a small battery pack, relative to these hypothetical vehicles. Whatever charging concerns we have with passenger vehicles are multiplied, and the owners of those trucks are unlikely to accept long downtime to recharge. If they aren't moving, they aren't making money.But all-electric truck fleets...not for long-haul.

Too late, Tesla is already moving production to China! (And, just a hint: It isn't because we're somehow "against" EVs. It's the cheap labor. It's always the cheap labor.)

They will be once China requires them to transfer all their IP as a condition of staying in China.

Captain Ned wrote:So, you're OK with Chinese IP theft from US companies as long as it hastens your EV nirvana? You don't think for a moment that China plans on paying any US company market value for the IP they require to be forcibly transferred as a condition of doing business in China, do you?

Captain Ned wrote:OK, Turing-bot.
superjawes wrote:The diesel-electric locomotives work well because it's really easy to move things on rail. Takes a bit to get going, but once you're moving, you don't usually stop, and you don't have to climb anything steep. The generator can basically run constantly at the ideal RPM, without any real load changes.

wierdo wrote:Interesting new wiring changes to cars in the near future:
Tesla's Developed a New Revolutionary Automotive Wiring Loom. Here's Y You Should Get Excited

Switching away from the old CANbus system to one more similar to computer networking, which means dropping wiring lengths from miles to hundreds of feet.
This may also introduce the concept of "plug and play" in cars where you can upgrade parts individually and stick them on the car's network through standardized connectors ala Ethernet and USB. Should make performing repairs much easier as well.
Hopefully this can become a common design approach for the whole industry, CANus is an archaic pain in the butt to work with sometimes.
ludi wrote:So it looks like Tesla overstated the meaning of the NHSTA's safety rating and the NHSTA both sent them a cease-and-desist letter last year and referred the matter to the FTC:

The real problems are the tests and the reporting are designed to let everyone have something good to say about their cars so they can sell them. Tesla wants to disrupt the apple cart and show that it has cars that are safer than anything ever sold.
