  • 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.


  • I work in Montreal.

    People biking year round are very rare, and dping so require significant effort compared to using public transit.

    I’m all for reducing car usage, but what I am saying is that solutions should be tailored to location.

    Bike work for Amsterdam, great!

    But I think cities where snowstorm are somewhat frequent should probably focus on public transit instead.

    ( I’ll admit tough that I assumed Toronto weather was similar to here and didn’t expect that much less snow! )









  • As weird as it seems, it may partly be external pressure.

    My precise height is 5’11 and a half.

    Each times it comes up in conversation, I tend to say I am 5’11, but people close to me insist I am 6’.

    I feel like nobody would insist if I was 5’10 and a half that I am 5’11, it’s just the magic 6’ number that make people weird.








  • I agree with the sentiment of your post, but I think the examples are a bit too far fetched:

    I’d wager most people use a computer/phone on a daily basis, which is why having a basic understanding of it seems like knowledge we should all have.

    Inversely, most people don’t need even have a turbo in their car and many don’t even have a car, so any knowledge relating to that is probably useless for them.

    That being said, even if someone is less knowledgeable in a field, respect should always be the baseline, as you illustrate, they’re probably skilled in something else!

    I’m saying that as an IT person that’s aware that I’m making money mostly because people don’t bother to learn all this, so in the end I don’t mind that much.
