  1. The frame in front of the AC box is the radiator support bracket. They are made of glass reinforced nylon supported by the front bumper beams. The rad bracket is rigid but not especially heavy.

  2. I would like to see Sandy cover the Citroen hydropneumatc suspension system. I believe it would work well on the Cybertruck. It integrates steering, brakes suspension height and body roll control. Far better than boring air bags. https://en.m.wikipedia.org/wiki/Hydropneumatic_suspension

  3. Lithium brines have been found under Dartmoor in Southwest England. Extraction uses two bore holes. The brines are pumped out, lithium extracted and the remaining brine is pumped back in. Dartmoor is intrusion of granite into rocks that were laid down and folded between 500 and 250 million years again. The area is famous for tin mines, copper mines, lead mines, ball clay (pottery) and China clay (fine pottery).

  4. If you want paint just get it wrapped.

  5. James Watt invented the condenser which made steam engines MUCH more efficient. Watt DID NOT invent the steam engine.

  6. My professor of electrical engineering didn’t have the amazing analogies of this presenter. But he was able to explain ac theory in easy to understand ways. I never struggled with even the complex stuff (eg running alternators in parallel). He was that good.

  7. I had a BMW 1200GS the huge boxer with two 600cc slugs whacking in and out. The 14 Amp hours lead acid starter battery weighed 5kg (12 lbs). I switched to a 4 Amp hours LFP weighing 0.8kg (2lbs) it kicked the engine over better than the heavy lead acid and was small enough to tuck away anywhere on the bike. The snag was poor cold performance. Easily solved by a heater pad and coolant conditioning in EVs.

  8. A scruffy looking weld is not automatically a bad weld. After all, we are not talking about a steam boiler pressure weld.

  9. The front mounted charge port is vulnerable in a low speed shunt. Probably not dangerous but it will ramp up repair costs.

  10. I really like the quiet “whump” into sound. Far better than geetar riffs.

  11. Long before Elon came along, Twitter was collapsing under the weight of self-entitled activists. They had to go.

  12. Sandy said after the CT launch that he was under a secrecy clause until midnight. This video was filmed significantly earlier when they were still building the line.

  13. Goodness knows why he called a HVAC compressor a “monument”.

  14. The DeLorean car was wrecked by its management but the external skin was very thin and easily dinted.

  15. Silicone RTV “instant gasket” is (very) old tech. The anaerobic gasket replacements such as Loctite 518 are far better and they cure only when air is excluded. Any excess will not create lumps that can clog oil galleries and it separates like a normal gasket.

  16. In U.K. smartphones and Google maps use the seven digit post code (zip code) for locating an address. However car sat navs often require a much longer address to be typed in. Why are motor makers so slow to catch on to such new-fangled ideas.

  17. The industry failed to go 48volt because the component suppliers refused to make the move. The failure was caused by outsourcing taking engineering design away from the OEM companies.

  18. The mega castings look beautifully made. Do the wheel arch covers prevent casting lattices filling up with mud?

  19.  @anydaynow01  Cardboard Aided Design. The best CAD by far.

  20.  @bearlemley  Door shuts with no gap is BAD. Especially as it can be solved with shims. That front door will rub the paint leading to corrosion. If the basics are wrong what have they shortcut elsewhere?

  21. Engineers think of good questions. Reporters just regurgitate what they’ve been told. They “report” often along with misconceptions that have no place in the conversation.

  22. The "best" system does the job with maximum reliability and minimal cost to source and install.

  23. My little Fiat is 13 years old. The internal reinforcing steel is not painted and there is no corrosion. It's not even deburred. Sharp edges are no problem when fully covered up.

  24. I normally detest passive aggressive but Elon’s 48V pdf files is just an awesome way to give Legacy Auto a kick.

  25. Steel under frames are notorious for corrosion. Out of sight out of mind. That steel control arm looks ripe for hidden and festering rust. It really should (at least) be wax dipped to seal all the rust traps.

  26.  @briansilver9652  There’s little point in squeezing into a typical EU car park space if your monster car prevents other car doors opening on either side of you.

  27. Is that a lead acid 12V battery? What the # is that about? A 5AH (maybe even less) LiFePo would do the same job, never need to be replaced and use a fraction of the space and save 5 to 10 kg in weight. If not more.

  28. In the 1980s, UK had Richard Townes, wedge-shaped cars and his series of glass sided Hustler cars. Citroen gave us the angular minimalist BX. Rover were also into wedge shapes. So I think Europe will love CyberTruck. The only is the large size. Our small roads and narrow parking spots will need something 3/4 scale. At least in width & length.

  29. The Tesla steer by wire has less redundancy than an aircraft but a car can simply pull to a stop when faults arise. Aircraft can’t do that.

  30.  @GlitterGuru BMW canned the i3, because it was too expensive to make.

  31. If the door mirrors are removed there should be similar sized screens inside the door. Drivers muscle memory makes that extremely important.

  32. Matt Jacobson it could be done with crashed cars or chosen parts from crashed cars.

  33. The battery architecture can be any voltage you like but individual cells are still 3.5 (approx). Higher voltages reduce system losses and busbar sizes but does that really affect the need for resistive battery heating of not?

  34. The segue way to the B-post camera was really well done. That’s beyond professional level work.

  35. The direct cooling of pouch cell tabs is a nice idea for phones, tablets and computers. However pouch cells in cars pose problems that cylindrical can cells (tabbed or not) don’t have.

  36. You need a serious ability to see beyond the obvious “this is how it’s done” is adequate anywhere else but these attitudes won’t cut the ice with Cory and Sandy.

  37. Every other electronic manufacturer builds circuits for their customers. They have ti be cheap and serve many masters. Tesla has one customer and is very good at defining what they want. Result is the low cost but extremely good equipment.

  38. Unlikely. Cars today have umpteen computer boxes all doing this & that and communicating. Take one away and the whole system falls over.

  39. Fiat have used a similar looking quick connect on the engine radiator hoses for decades. After a few years they jam solid and won’t release.

  40.  @nycandre  The mega machines mentioned by Elon are high pressure DIE-CASTING machines.

  41. Aluminium wire with the same conductivity as copper is 1/2 the weight but larger volume. For example, 6 AWG Al conductor will carry the same current as 8 AWG copper (60A) 4.1mm v 3.25mm. Al is better option for a rotating mass.

  42. Rivian is interesting but probably has no secret sauce. However Hummer represents legacy Big Auto. I would like to see how they propose to pull themselves out of the poo caused by EVs.

  43. Big Auto has pretty much developed a one size fits all approach. They don’t innovate they just rearrange what they have. Tesla was a green fields startup with no heritage to get in the way. But they still chose parallel shaft hypoid gears. Begs the question why they did not use the more efficient epicyclic gears. They are straight cut and use smaller shafts so overall costs similar.

  44. Mechanical and steer by wire steering racks are basically the same. Replacement costs should be similar. The power steering motors will at least double the replacement costs. However the car has two which can work independently but usually share the load. They should be more durable over time than the heavy 12v steering systems we have in today’s ICE cars.

  45. Sell it via a website and use mobile service teams. Nah! Nobody will consider that idea. ;)

  46. Peter Harris they used men in mines until they dropped dead. Same in both WW1 and WW2 and horses there as well.

  47. My school had woodwork and metal work shops, along with the usual science labs. But even then metalwork was for the less bright boys. REALLY! They had a sand casting foundry, lathes, milling machines, grinders the full nine yards. Though back then no CNC. I was apprenticed by the (then nationalised) electricity generator. I got the best general engineering training that was going. It taught me that what looks right usually is right. Today I see do much stuff that’s too big in the wrong places (excess weight) and too small in other places unreliable. I’ve just been given an adult push scooter it uses 8mm pins everywhere totally inadequate and it’s well bashed up. Mr car has huge cast iron brake callipers. They weigh a ton right where you least want the weight.

  48. Plastics that break today (or tomorrow) work perfectly well on engine inlet manifolds so why not accelerator pedals?

  49. There has to be a joke in here about Bolts catching fire.

  50. In my old job managers got promoted into incompetence with no way back to where they could be useful. That left the Indians run by chiefs who couldn’t ride or use a bow & arrow.
