  3. Tesla Truck Unveiling 11/21

    I noted emergency extraction as a risk elsewhere. My comment about visionary was intended to point out that as time moves forward, new use cases and requirements are identified, changing the value of features. You never know what man will discover. Tgat said, it’s worth noting The sharp lines...
  4. Rivian vs. Cybertruck

    which specs do you feel are game changers? I still don’t see the actual Battery capacity published. That’s going to factor into tow range. I like the stainless body... like a delorean. Will last a long long time. 25 year service life. But the cost of repairs. ... ouch. And emergency...

  6. Tesla Truck Unveiling 11/21

    I’m looking for evidence that this truck is real, and that Tesla has developed the concept sufficiently to be a real competitor, Vs. needing to push a public announcement to counter what seems to be a solid production plan from Rivian. First the base specifications that are essential to the...
  7. A Look at the Rivian R1T and R1S "Skateboard" Chassis

    I think that the modular design of the car has the potential to significantly reduce the cost of maintenance. It appears to me that the “skateboard” is designed for manufacturability, and designed to be produced reliably in high volume. If the quality control follows good practices, it should be...
  8. "69k to start" and general pricing speculation

    This thread is rising to the level of a pun competition. I know that as technical types, geeks, and enthusiasts we are bread to have puns as sour sense of humor. But the yeast we could do might be to take this thread move it to another thread. Buuuut.... as long as it’s here..... It’s winter...
  9. "69k to start" and general pricing speculation

    I could have told a bagel pun. But some of those get a little seedy. maybe we should stop now?
  10. "69k to start" and general pricing speculation

    mmm. Rolls. But... if you want to play with food, then waffles with ice cream and lots of toppings are more fun.
  11. Battery Pack configuration & Estimations

    Rivian has annonounced that their battery modules will contain 864 2170 cells and deliver 15 kWh. According to published data, the LG 21700 can deliver about 18 WH, so the math matches, at a module capacity of 15.6 kWH. Factoring the 864 batteries it seems to me that the configuration could...

  13. Economic Reasons to Buy an EV instead of a gas powered car

    I don’t know about warm fuzzies. But it is fun to engage, and enjoyment life has value. We have different methodologies for valuation, and both are comparative in nature. You advocate a non quantitative methodology. Sometimes that’s appropriate, such as whether to buy the chocolate or vanilla...
  14. Economic Reasons to Buy an EV instead of a gas powered car

    A great many people undervalue their own time, considering their free time “free”, when in fact it has a real value. https://www.clearerthinking.org/ Has an excellent tool for a rough estimate of free time, It uses comparative economic thought experiments to give a justification for a value for...
  15. An old whimsical wish for slow speed sound effects

    If it could only be so. Think about all the possibilities for customization if the light bar doubled as an RGB dot matrix display. So far i’ve Only seen two modes: green and white. But truly, truly I tell you: IF they animated the light bar and did the Wooh woooh sound.... I would be the envy...
  16. Regenerative Braking Capacity

    Technology as art is a legitimate reason to buy an EV, solar arrays, geothermal, supercomputers, or a 1985 Pontiac Fiero. Objective valuation is another valid reason for purchasing technology. Technology as a symbol and statement of sociopolitical ideology is also a valid reason. There are...
  17. Economic Reasons to Buy an EV instead of a gas powered car

    Operating temperature is a key parameter in doing a reliability estimate. Take any measured failure rate, and it goes up a factor of six as the temperature rises from 25C to 50C. When applied to inverters,a critical part of the car, keeping the temperature of the solid state switches low is why...
  18. Economic Reasons to Buy an EV instead of a gas powered car

    Thanks for the corrections. It surprised me that EV still lead acid batteries. But thinking about it you do need a low voltage source to boot the system. So tgat makes sense... and means that I could crank start this car with a hand generator in tfw event of a dead battery. coolant system...
