  1. But it will always remain a factor 3 more expensive than electricity.

  2. What on earth would be the benefit of a portable electrolyser? Where does the energy come from?!

  3. Waste and efficiency are not the same. Batteries will be recycled by the way.

  4. No, you cannot. Wrap your head around some basic physics and you will understand why 'self charging cars' are completely impossible.

  5. Genau!

  6. Well explained.

  7.  @lucrolland7489  Like Joe said, it just comes down to basic physics. This won't change in the future.

  8. Lol yeah let's not believe or care about physics XD

  9. Lol people still believe in this myth?!

  10. Big oil loves hydrogen and that is exactly one of the reasons why it is a bad idea.

  11. So... the energy for that electrolysis comes from where exactly?

  12.  @cerimite7674  Doesn’t that require electricity?

  14. horribly inefficient.

  15. Exactly this.

  16. That would only be one of the smaller downsides.

  17. Lol so much misinformation.

  18.  @lucrolland7489  Your complete comment. Batteries are lowering emissions a lot, even if fossil electricity is used. There are no entire countries are destroyed due to battery production. Batteries are not worse than diesel if you consider the fuel life cycle.

  19.  @lucrolland7489  Of course efficient mass transport is better. That is obvious. The question was whether EVs are better than petrol and diesel cars, and that is clearly the case. Here is a very extensive and recent report: https://www.avere.org/wp-content/uploads/2020/09/englisch_Studie-EAuto-versus-Verbrenner_CO2.pdf

  20. You sir are correct. This is the number one reason driving on hydrogen is a stupid idea.

  21. You have no clue. Elon is not hyping anything. He just made a decision based on basic laws of physics. If hydrogen cars made any sense, Tesla's would run on hydrogen.
