nvidia at least sells shovels, they already made some real profit unlike openai

How do you know that Threads won’t inject ads as posts?

Still no reason to defederate, huh?

I don’t know about going downhill in general, but there are some that use regenerative braking (regular braking, on flat terrain) so maybe

wait, 55 years old satellite still has fuel for thrusters?

yeah it’s replacement for google only if you don’t care if any of information received is accurate at all

fern? germ factories

there were a few stupidly close calls in soviet biological weapons program

2 means “just” removing earth’s magnetic field, van allen belts don’t shield from anything, these are trapped solar wind

5 could have side effect of disturbing ozone layer, on top of, yknow, just suffocating every animal

7 is not even wrong

10 sounds like CIA’s final plan for assassinating Castro: just let him die of old age

for now we can dazzle the most probable adversary with invoices

eight years ago war looked very different

The Most Insane Weapon You Never Heard About

looks inside

an insane weapon that i have heard about

anyway teller just wanted to make biggest boom possible and had a bad habit (for a scientist) of clinging to his original idea even when it was proven unworkable. “just make it bigger, then it’ll work” it never worked and never could. he also stole credit from ulam and was personal enemy of oppenheimer

this is less of a problem when you don’t use it for energy, but instead as a feedstock like in synthesis of ammonia or steelmaking. you can make ammonia in many places, but it’s not the case for steel

you’re probably talking about direct reduced iron and it’s really a problem that can be dealt with easily, just chuck a piece of coke when it’s molten for the second time in electric arc furnace (and maybe electrodes introduce enough carbon). substituting coke with hydrogen works also on “ingredient step” if you mean by that fuel needed to reduce iron ore to iron

maybe there’s a way to make electrowinning iron economical, and it’d be pretty green too, but i don’t know if it is workable

e: you can also avoid need for met coal if you use methane or syngas for direct reduced iron process

no we can’t make hydrogen everywhere, there will be regions with large excess of renewable energy compared to population. these places could export hydrogen. you also don’t need a lot of transport if crude is extracted near place where it’s used, like for example heavy crude from alberta

coal can be substituted to some degree with processes like direct reduction. hydrogen works but syngas from biomass or trash also works

file styrofoam under plastics

not now, but if hydrogen were to be used as an energy source/storage, then it’d be used plenty. same with batteries

this story was out almost a month ago https://www.theguardian.com/uk-news/2024/oct/16/russia-suspected-of-planting-device-on-plane-that-caused-uk-warehouse-fire

We did it not because it was easy, but because we thought it will be easy

ikr, but that tweet implies that all of oil/gas/coal ships would be unnecessary
