Does lprent know the front page hasn't been working all week?
The laws of physics haven't changed sine 2019. And I'd believe MIT ahead of anything Elon Musk says. Even without Cobalt there is still Nickel as a significant factor. Material cost will always set a lower limit even if you can argue where that limit is.
I think that people should read this. https://www.technologyreview.com/2019/11/19/65048/why-the-electric-car-revolution-may-take-a-lot-longer-than-expected/ Plans dependent on high EV uptake may be much harder to do than people think.
I did really appreciate your efforts in that regard to put your point of view across. You explained the facts very well but I don't believe that you did make a case that an engineering only approach was the only possible solution and I don't believe that ...
Perhaps now people will start to understand that buisness as usual has no future ( something that has been increasingly apparent for many decades now). I hope to see more mainstream discussion of things like degrowth but it is still going to be a big ...
Weka is raising a really important point here. There is a real need to try and extract peoples' real concerns from the toxic stew that has developed incorporating elements from a range of hard right belief systems. Some of them really are nuts and beyond ...
My concern is that the action needed is more substantial and comprehensive than most people understand or are willing to accept (yet). I do see signs of that changing or at least the possibility of change though. When people talk about a mandate it raises ...
To be fair to RedLogix, I think that his position is that while reduced consumption might be necessary he doesn't think it will be sufficient by itself. Hence his advocacy of new technology.
https://solar.lowtechmagazine.com/2018/01/how-much-energy-do-we-need.html I would recommend this source for all it's other content with the caveat that some of the thought experiments sometimes go a bit further than is reasonable.
It's good to see your position set out clearly. Some of the comments you have received have been a bit unfair and personal (That's the internet for you).
https://www.sciencedirect.com/science/article/pii/S0959378020307512 Something to read as per Weka's powerdown/degrowth posts.
I may not have been clear enough here. The ecological footprint claims that the economy is 1.5 times what is sustainable thus it would have to shrink by 1/3 to get back within those limits leaving 2/3. The argument goes that this resource base should be ...
"That's an interesting assertion I've seen made before, although I've never seen any research and numbers to back it up." As far as I know the main source comes from global footprint calculations. The numbers as I understand them involve reducing the size ...
"My problem with Powerdown as a concept is that it explicitly takes us backward toward the pre-fossil fuel era , without being clear on just how far back it wants to go. It seems to propose we can undo the physical basis on which the modern world functions...
I don't know Henry. But I recently came across the factoid that total US military emissions are equal to the entire emissions of south america. According to the interweb that is a population of 423 million people.
Thanks, I appreciate the sentiment. The internet (and the world) could do with a bit more civility.
"Ultimately, whether it’s a jet aircraft, a turboprop, or piston engine … the fuel source has to be carbon zero in order to deliver the outcome we want." I agree completely on that point. "And usually the people telling me this have pretty much zero real ...
This blog is relevant to some of your comment. https://smallfarmfuture.org.uk/ You might have to dig for more specific entries though.
An addition to the debate. https://www.lowtechmagazine.com/2010/09/piston-powered-aircraft-as-fuel-efficient-as-current-average-jet.html
I'm not expecting "others to to the work" if the "work" is a tech fantasy that stands no chance of ever actually working. I am just trying to be realistic based on the evidence as it appears to me personally . If you suggest something that seems like a ...
A nice idea but I will believe it when I see it.
He was in favor of a ban on petrol and diesel vehicles. I think that the current hype around EV's is wildly overstated and there are signs that things won't go according to those optimistic forecasts. Because of that I am worried that people will ignore ...
It's been reported that current international air travel volumes are at about 10% of "Normal". This is probably a glimpse of the future even if things do return to pre covid levels for a while. I didn't expect to be agreeing with I/S after what he said ...
I get the feeling that that there is more trouble ahead and there is still the potential for violence although "Civil War" as some say might be overstating things. More broadly I think that the cultural influence of the US will never again be what it was. ...
I know that this will put the cat among the pidgeons but a ban on ICE vehicles would be a pointless waste of time. Despite all the hype 100% electric transport is not and never will be physically possible. I don't blame people for believing the hype ...

"Biofuels and hydrogen are close to zero." Just a slight disagreement here. Hydrogen EROI is actually always negative not just zero. Biofuels vary from very low to usable depending on the technology and where the feedstock comes from and who you ask.
This kind of bad science really annoys me and does a lot of harm. The fact it came from a business school should raise alarm bells anyway. This is the main takeaway from James Renwick. "In short, the results presented in this paper are very implausible and...
There is going to be such an epis s***fight now. It ain't gonna be pretty.
I'd like to see some analysis of ACT's new MPs. I have a feeling that they have been cursed with success far more than any other party.
Thanks for the heads up Pat. A real shame it isn't up to date though.
