Biofuels have at least two huge issues:

The first is that solar PV has already well exceeded the efficiency of growing crops for fuel by multiples. Then there’s wind, nuclear, hydro, etc. Biofuels consume far more land than renewable and zero carbon ways of generating electricity. Even worse they consume fresh water. Electric generation consumes very little water by comparison.

Secondly and related to this biofuels compete with agriculture for food. You frequently hear about using farm waste but there is only so much of that. Our machines use more calories than we do so try to scale that up and soon you are growing crops for cars. That’s a bad path to go down in a world where population is expected to peak as high as 11 billion. Much better to run machines on stuff we can’t eat than to set up a competition.

The only good bet against EVs is in heavy and long range vehicles not cars. I am skeptical of electric trucks not because they can’t be done but because I am skeptical of our will to build out adequate charge infrastructure. But trucks account for a lot less liquid fuel use than cars so solving the car problem is a huge win. If we electrified light vehicles we could cut liquid fuel use by more than 50%.

That doesn’t mean all car companies should totally cease ICE production though. There will still be some market for them into the foreseeable future. I expect EVs to take the bulk of the market though.

A simple naturally aspirated engine takes bio-ethanol/e85 just fine, though the benefits seem limited to fewer fine particles, with comparable carbon emissions but a much larger agro impact.

What he's actually saying in the Reddit thread linked in the sibling comment is that the Catholic church condones slavery in some circumstances (I'd have to take his word about that, I don't know anything about church doctrine) and that insofar as the church is the expression of God's will, that makes it moral.

It's no crazier than any other religious belief if you're going to imagine some omnipotent deity just makes up whatever rules they want and they're beyond human reasoning.

I have no idea what the circumstances are in which the Church condones slavery, but it's not like the guy is arguing that we should reinstate plantations or that Epstein was a good guy who did nothing wrong or anything.
As far as I can tell, the majority of the cost of the development of the technology to take millions of tons to Mars is being funded by a private company.

That company's revenues, insofar as they result from what were once public funds, are primarily a result of projects related solely to the Earth (and perhaps one planned mission to the moon).

NASA is not paying for SpaceX to go to Mars. NASA is paying SpaceX to take stuff to Earth orbit.
> The rest of your complaints boil down to his overly optimistic timeframes

it boils down to the fact that he's lying. And he probably already knows it.

> and disagreement that making humans spacefaring / multiplanetary is a worthy goal.

Please refrain from interpreting what I say and write.

I do not necessarily disagree with Musk on that, I simply can differentiate from day dreaming and reality.

Mars is a worthy goal as much it is going to live on the top of Mauna Loa.

Or deep down the Marianas Trench.

Musk said it: he would like to go because it's a challenge, like climbing mount Everest.

That's all he cares about.

But lets also be absolutely real: he means send someone to die, he will never be fit to be an astronaut, let alone a space colonist. He's also not stupid enough to go towards certain death after having accumulated an enormous amount of money here on Earth. That he could actually use for the good, but, who cares, buying Twitter is more fun.

It's also honestly quite depressing to listen someone with so much money say that humans are worth only if they waste their enormous wealth on macho challenges.

He literally said that humanity will be much less interesting if we don't become a multiplanetary society, which, assuming it will be possible (I seriously doubt it) will take millenia, if not more. And once it happens, Martians won't be able to come back to Earth, because our gravity would crush their body.

How splendid.

p.s. I'm a fan of retro futurism. I grew up watching movies like Forbidden Planet and reading Asimov.

Musk completely ruined it for me.
When I was 12 my wrestling coach was getting his PHD in fluid dynamics. He gave a tour of the lab where he worked. On screen was a simulation. He explained that they fly a plane back and forth through a certain column of air in the stratosphere to get starting data. Then, using his model he predicts what the flow will look like over a period of time. There were specks flowing through the space onscreen. I asked what they were. “Bugs” he said.
Six years later I was sitting in the library studying and I slapped my forehead. “Bugs! Of course! Ha!”

I too was frustrated that they didn't say what the fuel was. It led me to believe that it's ethanol too. They just didn't want people to see the article as the nothing burger that it is.

I looked at several other sources covering this and they're all similarly quiet about what the fuel actually is. Looking at they supplier's (Coryton's) website, they boast about 'bespoke' synthetic fuels. So I'm guessing it's Mazda that's being shy about the details.
> "Treat warnings as errors" is a standard best practice.

It's a good general practice, as long as exceptions can be made.

Some compiler warnings are rooted in the compiler being unable to prove something that is actually true.
Why China’s Economy Faces a Perilous Road to Recovery
Yes, and: the question revolves around total financial and material capital needed to transition away from fossil fuels.

Synthetic fuels are potentially valuable because they allow existing capital assets (internal combustion engines and the industry that produces them, fuel distribution infrastructure) to continue to be used.

I am glad to see research into them continue- it's difficult to predict what will scale well economically in five or ten or thirty years.

The Arabic script has vowel letters, but they are used for long vowels only when writing the Arabic language. However, it is not strictly necessary to use the Arabic script that way. Several other languages use it like an alphabet and employ the vowel letters as such.

Some more drawbacks : 1. the plants are usually grown using fertilizers that are made out of, ironically, fossil fuels. 2. the process of turning the plant into fuel might also create emissions that need to be taken into account.

I agree with this, for provably wrong, generally accepted as wrong, or blatantly contradictory statements. But from a secular perspective, believing in god(s) is just an approximation or heuristic. Some people need or want that. For my own thinking I've judged it as an questionable axiom that creates a logic hole large enough to drive a bulldozer through, but to each their own. What actually matters is the conclusions and behaviors a person builds on top of it.

Most people are emotional, not rational. Even people who are supposed to be rational are rarely unemotional about their beliefs.

It's why facts and evidence are so unpersuasive. If you don't make them emotionally and personally relatable most of the population won't understand what you're trying to say.

Which is why the rule is "People won't remember what you said, but they'll remember how you made them feel."

Well, it's kind of obvious that the supplies of oil aren't infinite, isn't it? Is there even a theory that the oil is infinite? The peak oil is about timing and and cost, maybe it didn't happen according to the predictions but it will definitely happen. Besides the environmental concerns it also seems wasteful to burn away the stuff that is used for so many more things.

The synthetic stuff is interesting because it may actually be practically infinite thanks to the fusion reactor in the skies. That is because storing the energy from wind and solar in form of chemical energy solves the storage problem of the renewables. If extracting energy from that storage without polluting the environment becomes viable it can be huge.

I think it's more about finding an offramp for motorsports and classic cars (and some rural machinery) that are against electrification for a variety of reasons (both legitimate and illegitimate).

I don't think there is anyone at all that thinks turning agricultural waste into carbon neutral synthetic fuel for ICE has anything to do with "oil not running out" (which it absolutely is, demand is at all time highs, while production is at 30 year lows and no new major oilfield has opened in the lifespan of most people reading this, just saying).

I'd encourage you not to take his word for it, these are extreme views that are not reflective of Catholics in general (and I saw at least one person in those threads pointing this out, though I didn't read the threads closely). I've met at least one Catholic who would describe his views as heretical.

I'd also encourage you to reexamine if "slavery is okay sometimes" is really equivalently "crazy" to other religious ideas (like say, "love thy neighbor"), I think that is pretty uncharitable to religious people.

He might not address Epstein, but he does argue that "heretics can be executed as long as there's due process." That is some low key religious fascism ("it's okay to execute heretics as long as we control the government first"). Most Catholics I know oppose the death penalty (they successfully lobbied to make it illegal where I live, because they felt it was incompatible with their religious convictions).

Those poor billion dollar companies selling stuff with critical flaws should have been fined many decades ago (all the issues talked about in this tweet are literally 20 years old, I can probably go find a Defcon video from 20 years ago where they exploit the same bugs on the top 5 vehicle vendors).
