I think it’s likely we have passed the peak of R/D spend on ICE, but the momentum of research that has gone into it for decades is going to continue to produce innovations for a while longer.

The engineers are still there (where else would they go!) and with ICE development moving far out of strategic focus, there might actually be more room now for trying odd curveball approaches than back when ICE refinement was still a cornerstone of success.

Seems brilliant to me, as this is true marvel of engineering, contrary to electrocars which... well are not. They could've been should the engine be powered by fuelcells, but in their present form the electrocar movement took off only because of green deal, climate change, etc, which forced governments to allow business create the needed infrastructure of batteries and powerstations. Besides, you'd be surprised at th…

Yeah. It looks pretty cool. There is something satisfying about a complex mechanical mechanism. However, in its current form it is not the future. Combustion engines in general are not going to be the future. Hydrogen is a joke. Not energy dense enough. And expensive to make (energy wise). It also needs a vast network of gas stations.

Who says so? Batteries been available for hundred years yet we keep talking about fusion being the future, and we have fission. Which both drive turbines, which are a thing from the past? No? What is joke and when?

To me is a joke that we keep heating water to move magnets to get energy in 2024 with all the quantum entanglement, Johnson teleportation, lasers, etc. engineering magic happening around. And we do what? heat water to move magnets to squeez energy? So why is then hydrogen bad, just because it goes boom? Plenty of things we use daily go boom now and then, not meaning recent news, but in general.

I also invite you to take a look at the Tokamak and then try to argue again that metal tubes wired around to pump liquids and do some combustion is not the future.

Electric cars still consume fossil fuels. It’s just earlier in the pipeline. People love to talk about combustion engines being pollutants but few people talk about just how damaging it is mining for rare metals to make those batteries. Nor how harmful for the environment it is disposing of old batters (we haven’t yet solved the problem of recycling them either). And that’s before you even touch on problems at the po…

Most of these claims are dramatically false. - Electric motors use low amounts of rare earth metals, or in some cases none. Batteries generally don't use them either. - Automotive batteries have been demonstrated as >90% recyclable, far better than most materials we consider "recyclable" today such as plastic - The electric grid has sufficient capacity to onboard millions of electric cars without issue, and will not…

The grid is quite country specific. For example in the Netherlands there are significant grid capacity issues, so much that people with solar panels are paid on some areas to turn them off.

EV adoption here is high compared to the European average (similar to Norway). Public charging stations in affected areas are reducing capacity or even shutting down at certain times.

So grid capacity is an actual problem here.

Why should something be heavily vilified and taxed simply because you personally dislike it?

Because it’s a dead-end tech that’s holding us back and destroying the place where we all live. If you insist on pursuing it for your own pleasure, knowing what we all know now, you may be a villain.

Most emissions come from grid energy. The greens cancelled nuclear and were the real villains in the end.

So if you built your fortune on IT running in datacenters which consume magnitutes more energy to feed your customers; or else - if your business is about delivering stuff with 1000s of vehicles regularly being wasted... Tell me, at what point you start giving a damn about environment, and what pollution are we talking about at all? Sorry, but HN is full of people who made fortunes not giving major fucks about lots o…

It’s a ridiculous argument. You are typing this comment just because this damn not environmental friendly data center exists. But you pay nothing for HN. Hence someone’s do. That maybe this damn dude who made a fortune. But more than that, this dude has had to work hard long ago so that the data Center could be built and some nerds have got their jobs.

Telling people why they do things is 1) bad wording; 2) puts them in defense mode; 3) projection; 4) etc.. you name it not OK.

I pay nothing to HN, but HN exists thanks to lotta money moved around by people running HN. What are you telling me now, that HN would not emerge in some other form, had it not been for Founder Mode to showcase Algolia's search? Sorry, I doubt that it is how society evolves. HN can emerge from anybody persistent enough to go forward with it.

Slashdot, Craigslist, Reddit and 4chan if you want are very apparent examples of how smart people fill in when they have the chance. HN may well disappear very soon, I would miss all the smart voices, but I won't miss HN itself and the fair amount of very obnoxious people who tell others 'how they should feel, or felt'.

What that article doesn't address is the concurrent shift to electrify domestic heating. A worked analysis of the impacts can be found here: https://www.carboncommentary.com/blog/2022/2/11/how-much-ele...

It will take a long, long time to move to heat pumps for heating the majority of homes. Last time I looked into it I would have to change all the pipes and radiators in my home. Same with my mums house. The savings would have to be massive to offset the disruption and cost.

New houses are being built though. And at an alarming rate in some districts too

Presumably as Porsche is not about efficient transportation; it is about emotion, driving as an experience, making a statement, etc. Chances are there will be - or, at least, Porsche appears to bet there will be - a sufficient number of well-heeled enthusiasts who prefer the sound, smell and vibration of an ICE to the quiet performance of an electric motor. I am really curious to see how this pans out in a generation…

> performance cars should have ICEs After driving a fast Tesla, stepping into an ICE performance car feels like going back to a steam engine. A very slow, unresponsive steam engine. When avid petrolheads try a fast EV and feel the instant torque it will be an epiphany for them. Only the most stubborn will stick with fossil cars.

911 Turbos are faster than Teslas. Regardless, EVs feel like driving a washing machine. Some people are just not into that, or expect more. I’ve never been excited by any EV I sat down in, no matter how quickly they go 0-60.

I think many of people here live in US and assume that it everywhere things look similar. in my European country electric infrastructure is not ready for electric cars and with current energy prices this makes no financial sense. I own plug in hybrid and I live in apartment meaning I have no possibility to charge at home. near me (about 10 min of walking there is public single phase allow charger with 2 plugs machine…

> in my European country electric infrastructure is not ready for electric cars and with current energy prices this makes no financial sense. I’m always amazed by statements like this. People who have lived through the rollout of the internet to the masses can’t see how we’d modify existing structure to accommodate needs. We had phone lines initially, 20 years later now we have 5G, fibre, satellites. They just dug up…

You need to acknowledge that in Europe, the high price of electricity mean consumers aren't getting any discounts in money/distance ($/mile being inappropriate in the EU), if not being charged more to charge an electric vehicle over an ICE vehicle.

Saving the environment is nobel, but affording it is another thing.

If price hikes in the US continue, there are places in the US where that may soon be the case, too. Then we're screwed. Thankfully hybrids aren't going anywhere. They may be more complicated, but they have the most critical feature, regenerative braking. instead of shedding the energy spent slowing down as pollution and heat, it gets saved and is used to move the vehicle later.

So spend on that infrastructure instead, or mandate it. Honestly, spending resources on anything ICEs (outside of special industries) in this day and age is just wrong.

They're called sports cars for a reason. They're driven far less than everyday cars. They're fantastic fun. I'm an enviromentalist and I'd still buy an ICE Porsche. No EV has come close ... only the Hyundai ioniq 5 N seems to be looking interesting.

What are you looking for? Typically when people say sports car they mean high-torque (and thereby acceleration)... which ... you will not get an ICE motor that gives you similar performance to an electric drive
