  1.  @Scooper48  They consume three times as much electricity.

  2. Of course. Electric motors are typically much stronger than engines.

  3.  @dean1100110  ICE vehicles are and remain expensive because of their complexity and their exhaust gas treatment systems. EVs will (and are) getting cheaper because of scaling of battery production. We can already see the effect happening right now. And no, there is no slave labour involved with the mining of lithium. Nor is lithium mined in Congo. You are probably referring to cobalt, a material that is used less and less in EV batteries and there are already plenty of EVs on the road that use 0 cobalt. And again, this is not the time for energy squandering as we need to reach climate goals.

  4. lithium is not rare at all.

  5. Yeah. Terribly inefficient.
    3
  6. Nope it has not.

  7.  @ankur313  No. You just don’t like reality.

  8. Hydrogen vehicles are far more polluting than EVs.
    2
  9. It's not. Hydrogen is terribly inefficient.
    2
  10. but energy density by volume is extremely low.

  11. How is it possible to turn the steering shaft when the electric motor is not powered? As far as I know worm gears cannot be driven from the gear side.
    2
  12. Exactly.
    2
  13. It is not because it is far less efficient.
    2
  14. LiFePO?
    2
  15.  @B4nan0n  Lifepo4 is nice. Just built a little setup myself.

  16. Hydrogen combustion is terribly inefficient + you would still need gigantic pressure vessels to store the hydrogen. And no, onboard electrolysis cannot be done without an external power source.
    2
  17. Because it is incredibly inefficient.

  18.  @dean1100110  It is clear that EVs will be cheaper than internal combustion engine cars within this decade. Also, we simply cannot afford to waste insane amounts of renewable energy on hydrogen combustion for a very long time - it would actually slow down the energy transition. Also, ICE require a lot more maintenance which also adds a lot in cost. Plus: combusting hydrogen still causes NOx emissions. Last but not least: high pressure hydrogen tanks and the control system is expensive to produce and does not last forever.

  19.  @ankur313  Lithium is not running out at all and never will. Hydrogen production is inefficient and can only marginally be improved.
    2
  20.  @ankur313  That is the case with you, not with me. Again: inform yourself.

  21. You have no clue. Big oil loves hydrogen and is actively lobbying to promote it.
    2
  22. Very well explained.
    1
  23. Not at all. Hydrogen is a dumb solution.

  24.  @JerryRigEverything  kWh

  25. No you cannot. Onboard HHO generation is a famous scam.

  26.  @charleslanier1992  him is who?
    1
  27. No you can’t because where would that energy come from to to split the H2O?
    1
  28.  @ncphenom2309  So.. where would the hydrogen come from to power the fuel cell?
    1
  29.  @ncphenom2309  I am completely following. What you are proposing is not possible, as you already admit in the last sentence.
    1
  30.  @jimurrata6785  yup
    1
  31. It was a scam
    1
  32. There are many good reasons to abandon it.
    1
  33.  @basook6116  Hard to say.
    1
  34. Yup.
    1
  35. Not really. Hydrogen will only play a tiny role in vehicles.
    1
  36.  @mantas1906  Also the majority of lorries and busses will be battery electric. Simply because it is far more efficient and therefore a lot cheaper per mile.
    1
  37. Battery electric is far better than hydrogen.
    1
  38.  @jivewig  Cost per mile is far lower and the technology a lot less complex. Fast charging networks are a lot easier to develop.
    1
  39.  @dean1100110  Not at all.
    1
  40.  @dean1100110  Price per mile will be higher than a hydrogen fuel cell vehicle and far higher than a battery electric car.
    1
  41. Just physics

  42.  @realmamal  👍🏻

  43. Guess what the oil industry uses to clean your petrol. Exactly: cobalt.
    1
  44. Hydrogen will play a smaller role.
    1
  45. EV's are much less likely to catch fire than a fossil car.
    1
  46. It is not. Far too inefficient.
    1
  47. Because it is far more efficient, cheaper per mile and less complicated.
    1
  48. First, second and third question is answered in the video.
    1
  49. But far less efficient!

  50.  @ankur313  You could have thought so 10+ years ago. Not in 2023.
