  • Been a while I didn’t watch one of his videos, but I remember some US military stuff on there and I thought it was an interesting view from someone I think is smart but clearly doesn’t share my political leanings.

    Trying to not be in an echo chamber and all.

    Important to note that I don’t live in the US.




  • As far as I’m aware, the most impact around EV batteries is obtaining lithium and other componenets.

    Components that can and are already being recycled from older EV batteries.

    I’m curious to learn if there is other things I’m not aware of though!

    I dont think making a parallel between ev charging and hydrogen manifacturing is valid though: my understanding is that electrolysis is an option, but that most of the current creation is a byproduct of fossil fuel refinement, like plastics (which explains why petrol campanies push it).

    We can probably improve on electrolysis efficiency, but my hunch is that it simply won’t happen if petrol company can meet demand. Which I’m sure they will for just a bit cheaper than electrolysis costs to keep controlling the market.

    If we can produce green electricity, as long as electrolysis efficiency is not as good as the average battery efficiency whatever efficiency of the hydrogen engine itself doesn’t matter: it’s still less efficient than a battery because of the extra manufacturing step. And then there’s transport and all on top of it.


  • My own prejudice against hydrogen is around manufacturing.

    Most of the world current hydrogen made isn’t green at all, and the message is “we’ll figure it out once demand is up”

    And the companies pushing the most for hydrogen are petrol companies.

    I’m not a chemist, but it doesn’t seem to add up to me.

    I say that as an EV owner living in Canada. I need to use a fast charge station about 4 times a year due to cold related battery issues, and all of those time are because of extended road trips.
