    It feels like you're moving the goalposts to wanting EV trucks, charged at remote sites with a 100% clean minigrid just so you can be disappointed. That's a great goal, but every s…

    I'm commenting on your first paragraph in which EVs not being the majority of a mining truck fleet is taken as failure or hype. While for example Norway only has 30% fleet EVs desp…

    I generally wouldn't trust big mining corporations to do the right thing but that's some extremely negative framing. For standard EV cars in Australia only 20% of new sales are EV,…

    I think it's also a YC startup called Yoshi from 2016, I wonder how often those two overlap?

    Texas burns more coal than any other state and has hundreds of premature deaths a year caused by its coal plants.

    Electrification roughly halves total energy use in an economy. Fossil fuels are very inefficient compared with alternatives like EVs and heat pumps and renewables.

    Weirdly, one of the arguments Musk advanced was that is was all a front for the CIA, which I'd guess is closer to hard power that he was dismantling. Not something you'd expect to …

    Isn't this the guy that double counted everything? Because he counted when something got bought and then counted the subsidy used to buy and added then together?

    You've learned well from Smil how to make problems seem insurmountable by intentionally not approaching them with an engineering mindset. We know how to do 80% of electricity, 80% …

    They are saying economics is the primary weakness i.e. nuclear costs more than renewables even if you don't have fancy cooling methods that would increase the cost further.

    Yes but by a weird coincidence most of that heat can be provided by heat pumps at a similar 3-5x ratio.
