  • There have been some recent advances on hydrogen production. I don’t think this (sorry for the MSN link) is the one I heard of, but is an interesting example where cheaper catalysts are improving the efficiency of hydrogen production.

    Now, I don’t know if or when hydrogen will be more cost-effective than batteries, which are also experiencing massive advances. This is why I’m going to take the comment someone on Lemmy made about buying used EVs for the next little while - it’s cheaper, they’re lasting longer than predicted, and the advances lined up for the next few years are significant.





  • Honestly, Canada is a terrible target from a guerrilla warfare perspective. We have vast areas of emptiness that locals are familiar with but are dangerous if you don’t know how to survive there, many pocket communities that could easily hide insurgents and weaponry, lots of farming, which means lots of nitrates, a populace that can easily disappear into the American general population, and enough of an identity to not want to be absorbed by a different culture.

    I don’t think we could stop America from invading and occupying, but we could make Vietnam look like a walk in the park. So, who’s up for another couple decades of occupation?



  • There are two American rocket projects in the works that can carry a significant payload to the moon. One is using existing parts in a new configuration. It had one successful launch and cost $4B ($2.5B in launch costs alone). One is building a largely new system and improving existing elements and is estimated to have cost less than $2B so far, although it hasn’t reached the moon yet. That said, they have done 7 tests, at least 3 with a full configuration. How is that not better than the other option?

    Also, you are acting like there are no fundamental advances happening in space engineering. Sure, the physics is pretty well-known, but the engineering problem of landing and reusing stages/rockets commercially has only been done since the Falcon series, so I think it’s safe to assume the technology and associated product lines is still maturing.












  • I just read a blog where so done was expressing satisfaction that government was being scaled back to what was listed in the constitution, and encouraged people to take the 80k (which I assume is referring to the downsizing Trump is trying to do). Putting those two statements together, this person just effectively said that the FAA needs to be removed since it isn’t enshrined in the constitution.

    This is just to point out that some people vehemently disagree with you and France, no matter how absurd that may sound to us.
