@ExtinctionR @mortenlund89 An ICE vehicle burns its ***entire mass*** in fuel on average once every year for two decades.

The metals of both EVs and ICEs are mined once and then overwhelmingly recycled at end-of-life.

The lifecycle CO2 impacts of ICEs are *vastly* higher.

@ExtinctionR

@ExtinctionR @mortenlund89 Oh, and FYI, if your solution is "walk more", a walk powered by the average diet is comparable to that of an average ICE car:

Cycling is about half the GHG footprint of walking, but still only the lowest-impact diet cyclist beats the *average* EV.

@ExtinctionR

@ExtinctionR @mortenlund89 Now E-Bikes and electric mass transit with high occupancy are better than both of them,but that assumes density, mobility, minimal cargo, etc. Qnd we simply get back to the hair shirt issue: if your "plan" is "A 3-6fold improvement isn't enough, you must sacrifice everything...

@Calltoart I'm not going to waste time of the rest of your litany of falsehoods, but as someone with a hort background, let me dive into that picture, what it shows, and what it doesn't.

This thread will require a number of tweets, so wait for "The End" before responding.

@Calltoart

@Calltoart First: meet RuBisCO: the most abundant protein on Earth.

@Calltoart

@Calltoart You'll see it on this graph of the Calvin Cycle: it takes RuBP (a sugar) and a CO2 from the air to make two 3-PGA molecules. Every 3 times this happens you invest 9 ATP and 6 NADPH (aka, energy), you get half a glucose (sugar) out.

AI-generated art can have a dark sense of humour.

This is over a year old, but I just wanted to call attention to it as it's something I've been pointing out for a while:

forum.abetterrouteplanner.com/blogs/entry/38…

They plot the impact of wind on a Model 3 at different speeds and from different angles on highway-speed travel (100-120kph/62-75mph)

* A 10 kph headwind increases consumption by 19%
* A 10kph tailwind decreases it by 6%
But...
* A 10kph crosswind increases consumption by 8%.

Angled crosswinds are even worse - crosswinds 15-30% forward are nearly as bad as headwinds. Most people find this counterintuitive.

One of the key components of ensuring low drag is delaying flow detachment. As you see here, when the angle in the rear becomes too steep, the laminar flow detaches into a chaotic (high vorticity) low pressure wake (low pressure in the rear across a large area = high drag)

@JesseEMartin @jk_rowling @kristbogi "Protect a young woman" is a funny way to spell "Using her platform to spreading misinformation and successfully lobbying to override medical advice and horribly harm a young trans men and women".

@JesseEMartin

@JesseEMartin @jk_rowling @kristbogi And you have no clue and will never have any clue because you've been taken in by these *ascientific claims that are against medical knowledge and advice*.

*Children* - prepubescent - frequently (indeed, more often than not) reverse. *No* treatment is used apart from counseling.

@JesseEMartin

@JesseEMartin @jk_rowling @kristbogi Indeed, there would be no point anyway before puberty.

Once puberty starts, however, trans teens *virtually never revert*. Not just in the modern era, but in the entire history of medical study on the topic, despite that being *the main goal* through the vast majority of...
