interesting. yes, I agree with you on the huge point source polution is easier to deal with than little polution points that run all over the places. I have a little problem with the series of conversion of energy (as >>3623596 pointed out, convert from thermal-gas, to electrical, to chemical-battery, then to useful mechanical. That seems to be quite a bit of loss. If one can put a nuclear in a submerged station (maybe we'll call it Hugh Hamture), then it'd cut down on polution but still you still lose quite a bit of efficiency during conversion.

>>3623596

hmmm, he made a good point here. I don't know how Volt works to comment on but convert thermal to electrical, then chemical, then mechanical sounds pretty bad in term of efficiency to me. Unless of course, nuclear reactor.

well, usually the solution is to work in crew/shift, say crew of 10, 4 weeks on 2 weeks off. Something like current oil rig, only more peaceful and slightly more dangerous, still with enough foresight, danger can be dealt with and mitigated.

China, I'm not too sure, life is pretty cheap over there. I just hope the cost of training and equipment is high enough that they will do a good job thinking/planning it well instead hiring any beating heart to manned the machine.

well, you don't really build a geodesic frame to do fish farming, well not on the kind of budget we were on anyways, what we did was making a couple of huge circles out of plastic tube, link them together to make a sort of cylinder. The tube is the kind city uses for water main these days. Those come in standard length, so there has to be molding and welding involved. We should have gotten the fishes out before the storm hit, but it survived a 3 or 4 tropical storms or depression earlier couple with the fact that the storm moving in way too fast, that last ones proved to be slightly too strong.


On energy, we aren't in any of shortage right now. We are in shortage of energy for existing technology ie. oil. As far as other energy concern, we could use ethanol (not from corn, that's a massive scam, there are other stuff such as wasted wood, grass), natural gas among others like nuclear. The problem is hyping up mean more money for trader, seller, middlemen. They have to keep it at high enough level to maximize profit, but not too high that other form of energy will be developed and take over oil.

more iPad, iPod, iMat, iPhone, iEverything takes rare earth minerals. Well, we could recycle the stuff but it kind of more economical to mine it right now.

Well, there are problems both with undersea mining and space exploration, but I think undersea is slightly easier since you can sink massive stuff down easily vs. lift huge stuff up off the ground out of orbit. Energywise, undersea is still better. And yeah, like Mad Scientist once said, if you start living in the sea, you are forced to keep it clean or you can sue the fuck out of whoever polluting it.

nah, imagine 30cm diameter plastic tube molded and welded together to make the frame, the thickness was about 2cm, and still under normal sea condition wave you can see the thing bend like rubber. I watched over that for a couple of days, well, thieves and such. It sounds like a cliche but then and there I realize how small we/human standing in the sea. And how powerful the sea really was, and that wasn't even in tough weather. The storm came, broke the frame at the joints, ripped the net open, the net wasn't even small, synthetic nylon I don't remember the exact info but it was tough. In one go, 8 months of work was lost, couple of families saving was wiped out, mine happened to be the most. Nah if any thing, sturdier material will only make matter worse. My solution is to make it more flexible. The joint is the weakest point of the frame, making a flexible frame and joint can probably helps somewhat. If I remember correctly there have been talked about enclosure which you can sink the whole thing down when the weather get rough.

I love fish more than meat, but there is still problem for this though. You need lots of food to keep these guys happy, when they're hungy, the bigger will fight the smaller and try to eat them. Big fishes takes lots of food. And they can be pretty picky. But fish is awesome, all the alpha and beta omega acid you can handle.

>>3623333

fuck this bring back memory. My family did a project of this, grow huge fish in a fish farm about 2 km off shore. Fucking late tropical storm, break everything, suddenly all money was lost, when everybody within 10km of the region got abnormally big and meatly fish. Bankrup us, I could have finished my degree, then moved on to do grad work, fuck.

they put parachute or airbag/ballon on the car, crashed, the thing deploy, then the car gently floats down to surface. It's marketed as "a gently humanely way of going down". It'll sell millions.

it probably won't do any harm to the glass, steel can't scratch glass, but try it first on a mirror or a corner of the glass. I don't know what SOS pad was, but I've cleaned calcium deposited mirror/ceramic in bathtub with steel wool, work well, just be careful and don't put too much pressure on the glass.

scrapper, the thing that looks like a metal spatula. Or steel wool, the thick ones, not the thin wool.

>>3623138

I have no idea that it would be so complicated. My thought was that there might be some permanent station up somewhere outside orbit where sent package from far away would be slowed down then matched up with the elevator. But yeah, getting the stuff down would be infinitely easier than moving thing out of earth surface.

>>3622984

it smells awesome, but yeah, former gf can't stand it, putting it in container, inside a plastic bag, then everything inside a bigger container. then in the fridge. Can't understand why. Same with some south east asia sauces/dishes. In my opinion, it boiled down to exposure/culture/perception.

>>3623059

well, once we have enough material and tech, we can do it in stages, first send whatever stuff down to some station near earth, build a space elevator/bucket systems, like moving chunks of stuff in a huge industrial chain down to earth, dump content out, then move it back up. This shall be done so.

>>3622896
yeah man, I love the idea.
>>3622921
great metaphor, loving it, stealing it.

they then can just impose a tariff on your wealth, say the import tax from outer space to earth. Or some slogan like "buy Earthican". I don't know man, you might have 10 000 ton of gold but if you can't bring it down to Earth, then it'd be useless. Well, that idea of colonize Mars suddenly look pretty attractive right about now, eh? Oh, thanks for mana, I didn't have a chance to say it, I think you were banned right there and you took some time off /sci/.

there is false common sense the size of a semi through. When one lives in rich and plentiful, one rarely worry about anything else, innovation and advance often came from disadvantage situation, shortage. Imagine, walk in the jungle for 30 mins and you have lunch every day of your forefather, grandfather, dad, and yourself, why the hell would one then need to cultivate stuff, grow stuff, make it more streamline. More evidences, cheap oil, big inefficient car. Fishes in ocean, big ship, small mesh size. Lots of messenger pigeons, hunt for fun, bucket shots, etc.

actually, I think perception is the main reason. Or if you prefer, psychological reasons. Taste & smell are mainly chemical, the signals sent to brain however are interpreted and with past experiences (perception) form reaction. How perception/psychological factors explained, I have no idea. I'm pretty sure emotions influence taste/smell too.

acquired taste is the closest I can think of. There might be lots of explanation. Culture, what you're used to, say you grew up in culture where eating insect is common, you will find some dish mouthwatering, whereas your friend might throw up at the thought. OH, btw look up Kiviaq, my roomates almost lost their meal when heard about how it was made. My friends love it, and swear I'd like it too, I'm looking forward to try it one day. There are other ethnic dishes in south east asia that would never ever ever be mentioned in any popular cooking books, may be in the section "they eat WHAT" kinda.

fucking 10, oh well, I'll join the special class now, wheee, that means I'm special and you aren't. That's why it called special class.

well, shit. And I thought it couldn't be shittier taking money away from NASA and space shuttle; they killed the new scope. It's now appeared that we still have some hope yet.

swim from Korea to Japan, or find the right people to smuggle you in from China/Russia to Japan. Not going to be easy, or have some ship drop you off in some of the debris, then call the coast guard, claim you lost everything in the earthquake, live for the last 5 months eating nothing but wood. Amnesia too. Sell movie right to Hollywood, ditch that anthropology degree.

no, you're in the wrong board, common mistake, it's /b/ you're looking for. Now off you go, we only do mundane, useless things here

take a can of pop, show them in the ingredient, citric acid, nitric acid, etc. tell them, "if you drink that shit, you'll die" show them the orange juice, point out the acid, tell them drink that shit and die. Give them a bottle of vinegar, show them that it's acid, open the bottle, pour it on their head while shouting die fucker die. Hopefully after 3 of that, they'll leave you alone. Logic, ha, good luck with that. If they can't handle a little reading, what make you think they'll understand logic/fallacy.
