    You do yourself, and intellectual curiosity, a great dis-service when you paint with strokes that broad.

    I agree with you. It would seem that the response to Covid has rapidly accelerated all that was going wrong with society, while largely halting all that was going well.

    It's incredibly disappointing to see MIT put its name to some apparently PhD-level research that claims over-unity efficiency, and apparently (according to the picture) using a few…

    For that to work, each successive layer will need to remain cool enough for water to condense on it.

    It's a struggle, looking for long-leg trousers in the UK. Next also has them, and their one-from-cheapest range is good enough for me.

    For healthy people, Covid is not so bad. The data has shown this since early 2020, but try telling that to anyone.

    I am so glad I got out of the whole game, and stopped using a smartphone. I'm also glad I live in a country where it is somewhat viable, although in our post-Covid world, everywher…

    So it turns out the original "disruptors", using scorched-earth business techniques, and despite adhering to the mantras of open-source software, have become uncontrollable monster…

    They share at least one property - you go broke slowly, then very quickly.

    If it really were about shifting energy usage from fossil fuels to a "renewable" power grid, there would be an equal enthsiasm for electrifying all home and hot water heating. Ther…

    My "best argument" is that driving less, maybe combined with switching to a more efficient / smaller ICE car, could do as much good as buying an EV. It also avoids all of the new e…

    As you ignored my comment on our other discussion, and continue the conversation here - I also assume you have electric heating and hot water at your house. After all, everyone nee…

    Yes, modern engines are optimised for fuel and emissions efficiency to within an inch of their lives. This was my entire point - we could move a couple of people in a Fiat 500 and …

    That wasn't anywhere near the point. OP was talking about the amount of energy required to raise the entire ocean by one degree, which is a truly terrifying amount of energy. Fortu…

    Why would I do that? I've already made significant choices about the way I have arranged my life, so that I am not reliant on a car. I have already more than exceeded any CO2 reduc…

    Yep, there are modern engines that will do that. I was using the example of an older engine, because they are generally much more fixable (which was OP's original point).

    >"Much simpler" I don't think so. I bet you could make a reasonably performant ICE from scratch, yourself. By "scratch", let's say - from chunks of any homogenous material you want…

    The Fiat 500 from 1957 got 43mpg. Imagine what could be done, if car manufacturers were not focussed on the lease market, meeting the newest emissions regulations (more relevant in…

    Excellent. Then I will continue running my cheap ICE, avoiding the cost and environmental damage associated with an EV, all while cycling to work and other destinations as much as …

    I'm aware of those numbers, and they are still both an environmental cost, regardless of how they happen. EVs swap high environmental running costs for high environmental manufactu…
