You've done a bit of a bait and switch, "fulfill their dreams" and "decent quality of life" are two very different standards. One, sure, we're in a society and sometimes that calls for sacrifice, the other, if

A structural question comes to mind, if the pipes are arrayed horizontally, how important is it to keep the pipes straight while they're being compressed by metric tons of biomass? Are they at risk of being squished closed? It's t

Yeah, spaceX is an aerospace company, what business do they have saying the environmental scientists have no idea what they're doing? It's trivial for them to complain and get them crucified in the court of public opinion because

but there was a critique, your proposal was "something something let an army fix it" and they provided context "something something various armies caused it."

I saw an interesting review[0] from a climatologist talking about the biggest scientific inaccuracy isn't what you'd think. The mega hurricanes that freeze jet fuel in their eyes because they bring down super high elevation air? A

I assume you're using "performance" to mean "kwh/kg", which is a bit of a narrow view. Even if they had have the gravimetric energy density, grid storage doesn't care about that. With an annual growth rate

I would contend the coal lobby successfully killed terrestrial fission power. It would have been a good replacement in the 60s and 70s when solar was still underdeveloped but now solar has worked out enough kinks that it's intrinsic ad

Mentioning the pedal assist bikes is important, for the amount of battery a cybertruck ships with, you could ship 400 of the ebike I use for 90% of my trips.

I think two-word contranyms are more concrete, like "fight together". Oversight is a less ambiguous example of a single-word contranym.

Given the current lower bound of one passenger in personal vehicles the process for using driverless cars needs to incentivize car pooling to the point that the average occupancy of traveling cars is considerably above 1 to make up for all

I think what the parent post is referring to is that clarifying human intention rather axiomatically involves a human at some stage in the process.

there were a couple automated urban lines in pre-90s. If we hadn't cannibalized the inter-urban trolley cars for public roads but private rails in the 1920s, who knows what would have happened.

Well we have juice boxes for that now. Krakens are still a problem though.

no, it isn't. Over the course of a few decades, a kilogram of methane has the greenhouse impact of ~50 kilograms of CO2 because of the different absorption modes methane has that CO2 doesn't. If terraform leaks more than a few per

My generous interpretation of OP is that during the covid pandemic our precautions that kinda-sorta slowed down covid were adequate to basically remove influenza from the human population as indicated by being the least amount of influenza

I said a /comparable/ bike, single speed, steel tubing, medium precision chaining and teeth on the gear. A similar price will get you a wildly superior bike the likes of which was well beyond their craft, quite serviceable pedal a

I've recently visited the aerospace smithsonian and they had an exhibit on the wright brothers. I'd known about their prior careers as bicycle makers and repairers, but the thing that really grabbed my attention was the price. For

Well, the global system has a lot of mass. It'll take time to fix the things we've messed up. To survive in the interim while we do that, there'll need to be some harm mitigation measures.

If the planet had a decent magnetic field, it might actually be quite easy to navigate. A sextant would get you "solar latitude" as it were (the angle of the sun relative to the horizon defines a circle), and coupled with magnetic

The precision in the physical construction of the proof though does help in assessing it's validity. If the insight was completely divorced from the visual representation then you may as well be doing straight up symbolic algebra.

Are those advantages worth inherently worse amortization costs on the first stage though? A TSTO can have one first stage for ~10ish orbiters since it's only used for 10 minutes while the orbiter has to do all it's supposed to do

One way the super wealthy can over whelm the intent of voters is through emphasis of information. It doesn't matter if candidate A supports 2 or 3 things most people like, if they also support or symbolize something they hate. By empha

Rough calculation get's me a dyson sphere big enough to bring the black body radiation of the sun down to ~4k being hundreds of times the orbit of pluto. At that point it's actually an interesting question of where you get all the

$15/MWh is 1.5 ¢/KWh, right? that's pretty darn cheap and means that the other 10~20 cents would be transmission and fuel, yes?

I can't find it, but somewhere I read the sentiment that `Snow Crash` is best read by young men. I know I read it when I was in my early 20's and enjoyed it, have at most skimmed some amusing passages (like the bits from the persp

Assuming something like air space territories in these other cultures, extending them out to infinity seems... tricky. Wouldn't it imply that the ownership of various celestial bodies changes with time? My recollection of how it evolve

The thing I often think about is while the demands for an orbital class vehicle quickly become untenable, ICBM's stay viable for a lot longer. I don't know if MAD is more or less stable without the prospect of space exploration.
