/sci/ - Science & Math

i know, but it certainly helps with efficiency
the plasma gremlins will still rear their ugly heads though

>>5968521
i'm sorry i can't hear you over my 90% fusion neutron capture

>>5968385
few if any on /sci/, and generally it's in threads of the form
>what type of engineering should i go into /sci/?
or navy nukes

>>5968347
>DPF
i have a soft fuzzy spot in my heart for plasma pinch fusion <3

and speaking of which

quick, we need a nuclear energy thread to contract the /x/ spam
anyone else a little excited for general fusion's MTF prototype?

but LEDs have been shown to increase aggression because of the fucking headaches they give you.
well, they haven't been shown, but god damn dude

we do
its called geothermal
and it has lots of logistical headaches unfortunately, unless you live in hawaii or greenland

yep, that's pretty much it exactly
however if reprocessing was better and more efficient and cheaper, the "wait time" would be somewhat lower since you aren't worried about plutonium radiotoxicity still in the thousand year range though.
and keep in mind the transition from "bad" to "totally not radioactive at all" would take millions of years. we're only really concerned with the radiation dropping down below background radiation levels.

this is the downside to popsci. it gets some kids into the actual field who wouldn't have otherwise but it popularized some real cringe-worthy face-palming bullshit like quantum mysticism

>>5933948
yes, quite well, and the internal heat of the earth would keep us warm for a very long time
use geothermal for everything (including lamps for growing food) and given advanced enough technology it could be downright pleasant.
of course this assumes building enormous underground cities magically becomes feasible with pixie-dust steel that can support underground domes

also, i dont feel anything about it right now
i'll feel something when he puts money directly towards something in the field, instead of just mentioning it

>the universe has a limited supply of energy
>energy runs out
NO
STOP IT
FUCK YOU

well, fukushima really wasn't that bad at all
two years later, the only lasting effects have been a few funky plants and some butterflies with weird eyes. that's it.
the exclusion zone has dropped down to like 5km around the plant, or maybe it's down to 1km by now?

it's a big expensive mess but it's not really a health hazard anymore.
however the japanese media makes it sound like every can of soup in the nation contains plutonium or whatever, i think that's the major galvanizing factor over there.

>>5930774
because turrists.
mind you, that's not an idle concern. even without directly fissile material, a dirty bomb is a fucking horrible way to kill lots of people and scare the fuck out of everybody

>>5930241
>he thinks those men aren't going to pump money into it to make their own patented designs
they aren't stupid. they have seen what happens to industries that try to stand still in a moving market.

hell, i'd by a Shell brand backyard eco-actor or whatever they call it.
don't buy a BP though, i hear they get leaky

AW YISS
if gates spend 2 of his 70 billion personal fortune or whatever it is, we'd have a working prototype in a decade

>Radiation isn't something to be feared, it's a risk that can be minimised like anything else, it's just a little harder to actually measure the risks.
i love you

>>5880546
its lots of little things.
another factor is the mentality of poor people to "try a bunch of times for a bread winner", hoping if they have enough kids one of them will go to college, get a good job, and pay for the family or something.
and as you said, easy access to contraceptives is probably another larger factor

>>5880542
basically every country that has ever transitioned from first to third world (in the past century at least) has seen its birth rates tank like crazy.
from 8 kids per parents to a much more reasonable 2 or 4

invest in developing nations with micro lending and micro finance
bring everyone onto the internet and make farming resources readily available
make GMOs cheap to buy and plant

the american farm belt could very easily feed the world right now but government subsidies to farmers keep them from bankrupting the food market (which would be a really bad thing. subsidies are ok)

if all potential farmland was brought up to second-agricultural-revolution standards, i don't think a single damn person on the planet would go hungry. there'd just be too much food.

that said
>easy way to stop overpopulation; bring economic growth and eventually prosperity to high-birthrate nations. birth rates plummet entirely on their own. we good.

this

>the centrifuges need to spin very fast, at at a VERY SPECIFIC speed, continuously, for a very long time
>you need an absolute fucking shitload (official SI unit) of centrifuges
>the centrifuges aren't particularly cheap
>the centrifuges aren't cheap to maintain, mostly because of high stresses and you need a load of them

the real killer in the whole process is the lack of chemical separation. can't separate isotopes except through "mechanical" means.

it's basically a giant pain in the dick (again, an official SI unit)

>>5856191
its "they dont think it be like it is, but it do"

mars one; probably fake or just a scam, if not, could be kinda interesting, depending on is nasa uses it as a landing site or possible central hub of future mars base

>look up that we the people site on a whim, wonder if it'd be possible to get some energy policy reform going though this?

oh crap
