Naw, we do better than that now, the Toyota Prius is over 40% and F1 engines are over 50%. If someone can work out a good turbo compounding system for road cars we've got some room to run.

I think so. bigger truck diesel cycles can push 40-45%. large slow speed marine diesels with a waste heat boiler driving a turbine are better than that, CoGas (gas turbine paired with waste heat boiler) is currently the best and I think they get close to 60%? but it’s been a very long time since I looked at that, like decades now. Steam plants even with reheat and high superheat have a hard ceiling around 35% because they need a condenser as part of the cycle.

If someone can work out a good turbo compounding system for road cars we've got some room to run. that’s a hybrid so yes it will be better than a straight IC. I’ve no idea what the hybrid limits are.

I think it can be simultaneously true that western auto manufacturers are gearing up the infrastructure to take a stab at transitioning to EVs, and also that it will be an enormous fiasco for a million reasons Also wtf Elon was a co-chair of open AI? Lmao if I had known that from the beginning I would have been much more able to convince people to temper their excitement

We're also not getting nearly as many thermal losses when we do electric, especially if we're not doing thermal-to-electric stuff, like natgas, coal, or nuclear. I don't know where you're getting the 3x energy usage. It's true that energy *density* of gasoline is about 3x of what an ideal lithium battery is, but that's a very different thing, especially when our ability to convert petrol to "move stuff" tops out at around 30ish percent efficiency. Peep the energy differences between the "actual move poo poo" in transportation and the 'rejected heat energy'. From there, take a few seconds to think about how the energy will go into making batteries, which bumps up industrial energy usage, and not 100% electric. Toss in the round-trip efficiency of electricity being 90ish for batteries, and it's less impossible and more merely "difficult". That being said, mass transit is the actual answer, but here we are, with a better-than-nothing answer. Joey Steel has issued a correction as of 23:22 on Nov 17, 2023 |

There's just no way any major nation electrifies significantly before 2035 or even much later. The timescales are too short and the tasks too big. The UK has already flip flopped along with EU nations on when to ban ICE sales, and they're a fraction of the total transport emissions produced by oil industry. A faster and more likely alternative is to just go all in on hybrids because fossil fuels ain't going anywhere, and those resources for EVs are better put to use in making ICE more efficient than making far fewer actual BEVs. But WWIII or the AMOC shutting down will happen sooner, so I can't really care too much.

And don't we already have a notoriously fragile grid that's overloaded every summer, summers which are getting hotter btw, where replacement parts are on 18-24 month backorder? Like, we barely maintain the poo poo we have now, let alone build up in anticipation of future demand, which I'm told is dumb bullshit the Chinese do for things like housing

You know how the Kyoto Protocol is the framework that setup the entirety of the laughable and useless carbon trading market? Despite it being useless at actually doing anything it has employed lots of people and everyone knows exactly how many emissions every company and person adds to the atmosphere. Every corporate and finance entity is going all in into sustainability and making sure their financiers and customers know that. Biodiversity loss is for the very first time something that capitalists are paying attention to. But there is no Kyoto Protocol going to happen for that because there is war in Europe and the Middle East is a poo poo show and westerns countries are no longer capable of functioning. Every industrialized nation is gearing up for lots of war and you can’t go to war on solar and wind energy. You can’t use biodiesel to fuel fighter jets or Reaper UAVs. The beginning of the end is happening now. Enjoy your time left. Biodiversity loss and the brunt of the effects of Climate Change, like many other things, will be mostly felt by the generations that came after the boomers. Enjoy!

gradenko_2000 posted:"Look, you can't just BUILD a library"  "Look how much simpler (and therefore better) it is when you just say what you want, and ignore the steps necessary for making that work!" Like don't get me wrong, I'm a big fan of public libraries, but subsidizing book consumption would be way simpler to implement than running public libraries. Both plans would require funding, but that's about all a well-designed subsidy would need. With libraries you need to build physical facilities, you need to decide where to build those physical facilities, you need to staff them, you need to decide what books to buy and how many, you need to decide when to remove books from circulation, and so on. That cartoon's probably the clearest example I've seen of "My ideas are better than yours because I'm counting on Implementation Fairies to make everything work" on the left. On the right, of course, we have Donald Trump promising endless winning and better health care, and of course Ronald Reagan's famous rebuttal to Jimmy Carter's health care proposal, "There you go again.  "(Here's some things that are great about public libraries: they're a public space, which is something American society desperately needs. They're a quiet public space. They're free to use, so you can explore lots of books with minimal investment. They're free to use, so children have access to books. Librarians are less mercenary than publishers so they're more likely to promote books on merit rather than profit. Librarians can help patrons research and guide them to books they might be interested in. Note how none of these things is "library systems are easy to set up and maintain.")

Think about bullshit jobs (hell, read the book) and how much of it is The Economy. Now, delayer the economy as more frivolous uses of energy become unsustainable and more energy is directed to basic upkeep. Keep doing that until something breaks. Or just keep digging up more carbon to burn and get those rookie numbers of 5ºC by 2100 blown out the water.

And yes, having my car's entire mass as just your "fuel tank" to try and get the range I get is certainly not a great selling point. I mean, if you're anyone other than the modern SUV/truck lover. I got a 1-litre, 3 cylinder Fiesta MHEV that gets me ~60 MPG US on the motorway. But it also only weighs 1600 kg, which is less than the weight of the Hummer EV's battery pack, IIRC.

Calling our petrol usage 3x times our electricity usage, however, is overselling the problem. It IS really difficult. Impossible, sure, given the current political climate and the inherently bad decision that is "more EVs" and not "electrify rail, and build public transport".

Personal electric vehicles are not heavy enough to be noticeably different on the road (tire wear isn't in my wheelhouse). Roads only start getting worn out quickly by vehicles when you toss semi trucks full of sex arses on the highway.
