#192The stumble over abandonment of ICE vehicles. By 2030 (8 years from now) at least six manufacturers will have stopped making ICE vehicles entirely, and India claims it will ban the sale of ICE-only vehicles. By 2040 (18 years from now) over half of all new cars sold will be electric, and the UK and France claim they will ban the sale of ICE-only vehicles. However, there's still not a plan that makes all that sustaina…
ICE = Internal Combustion Engine for other non-native who wouldn't understand how a vehicle can work on ice
I thought he meant the German ICE trains and I was really worried for a second.

#193Conscious realism and the cosmological polytope: https://www.youtube.com/watch?v=reYdQYZ9Rj4 https://arxiv.org/abs/1709.02813 According to Prof. Hoffman, this model of the universe is highly parsimonious in that it can model data from the Large Hadron Collider using a single parameter, while the best incumbent (Quantum Field Theory) needs millions. The implication is that everything we see and experience are not fund…
That's a lot of words in those links. What falsifiable predictions does this make?
OT: Let me give you a guessing, maybe the Translation wasn' wrong at all, 'Watts per Pound as an Ratio' -calling the Movie Matrix to mind... ^^

Also note that “half of all new cars sold” does not mean half of all vehicles on the road. People will keep using their ICE cars for 10-20 years after their manufacture date. I’m curious to see the actual projections of cars on the road that are electric vs ICE. My guess is, by 2040, it might be 25% (in the USA).

#195Energy? I feel like it's been talked about a lot but maybe not? Solar panels are dropping in cost at an exponential rate [0]. As of this writing, consumer "new" panels are $0.75/W and used are at around $0.30/W right now (I won't give a link as a Google search will do). Battery technology is also dropping at an exponential rate. I believe, with a little effort, one can purchase batteries at about $0.08/Wh. Taken toge…
I wouldn’t get too excited for decentralized energy. More energy sources means more power lines all over the place. Few things get NIMBYs worked up like power lines. The social aspect will be harder to solve than the engineering.
I would like to see a more in depth treatment than what I've seen (or what I've thought about).
Certainly cross country electric lines aren't going to needed as much because the energy can be produced by a relatively clean factory. With coal, we want it very far away enough away from consumers so as not to cause health concerns. Decentralized energy, at the very least, means we can create solar power plants next to larger cities and towns.
In terms of the wires in urban centers, I don't have a good sense. I can see where you might be right but at the same time, that infrastructure is already there and there are efficiencies to be gained by not transporting electricity over many miles of copper.
I also agree that the social aspect but there's a large pressure to find solutions because energy costs are going to be dropping by an order of magnitude or more.

#198Russia will collapse.
I feel like this definitely needs to be expanded. What makes you think that? Their currency is stronger than before the war (despite internal fragility) They have the entire continent of Europe by the balls on oil/gas They've made an absolute killing in the energy sector this year due to the fear and scarcity they have created. They're making steady gains in their war in Ukraine They have the ear and economic heart o…
All of these are illusions. The currency is propped up by the government because it's not freely exchanged anymore. Europe is making a massive turn away from Russian energy despite the medium-term pain. The Russian military has achieved very little in five months of warfare. And China genuinely doesn't care about Russia. If the Russian Federation were to balkanize into smaller states, the Chinese leaders certainly wouldn't mind.

#199Earlier quoted context omitted.
Something about this cannot be right, surely? You are saying one can invest in a solar setup and have 7+ years of free electricity, and all that starting after 3.5 years?
I have been living fully off solar (and some wind here and there) for 10 years. Its amazing. Never do I stress powerlines going down, brownouts, etc. You can run a fridge, lights and a laptop 24.7 on about $300 of solar. You can add panels as your needs and budget increases. The biggest cost is the battery.
Do you have a writeup of your setup? Do you use lead acid for your batteries?
Besides the money issue, the biggest concern I have are balancing the batteries, getting the right inverters, keeping the panels clear and figuring out what inefficiencies are during the non-summer seasons.

#200We saw a post the other day about using DALL-E and GPT-3 in conjunction with one another. I think more of these systems working together is going to revolutionize basically everything, especially when democratized with cheaper consumer hardware.
Did DALL-E and GPT-3 revolutionize anything yet? (I know it might sound snarky but it's not my intention, I genuinely wonder how they're used today, other than demos)
Revolutionize? No. I don't mean DALL-E or GPT-3 specifically, just that tech. I think as the hardware needed to run these gets cheaper and the tech is applied to other domains we will see revolutionary changes. My vision depends heavily on the forward march of progress with bigger better compute available cheaper.
