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 baking trays and tinfoil. It also does not explain how

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, everywhere seems to need a crappy app to get anything done.

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 monsters? It should make you think a little about how thi

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. There isn't, for two main reasons: 1. Making resi

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 environmental issues caused by the materials r

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 needs to do everything possible to reduce fossil fuel usage, ri

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 get 43mpg, in 1957. Without the incentives I mentioned in my

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. Fortunately, that's not what is happening.

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 reduction that an EV would provide over it's life, and

by ppf 5y ago
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. You would have absolutel

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 Europe), and filling cars with electronic toys.

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 possible.

I've seen plenty of numbers reported, but I think I made a reasonable estimate. I'd be curious to see what you have found. This paper does seem to indicate that the estimates have come down recently: https://www.mdpi.co

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 manufacturing costs, and then we in developed countries external

I dislike being told what to do, when their assertions make no sense to my life choices. Especially when most of the arguments boil down to "most of the environmental benefits are not going to happen yet, but soon!". My personal c

If you can "feel" climate change happening, then we have left the realm of science and entered the world of spiritual emotionalism. It sounds a lot like Evangelical Christians who can "feel" the Holy Spirit entering them

There's an astronomical difference between the surface temperature and the temperature of the entire ocean rising by one degree.
