Comment Re:shrinking amounts of land available (Score 2) 376

Interesting, however it still smells of a solution looking for a problem. Though the reflex might be to believe that there is no land to grow beef ( or any other meat ), due to factors such as urban sprawl, we have yet to conquer major portions of this earth with city as yet. There is still plenty of land from which to graze. It should not be a surprise, in this day and age of "everything is a potential catastrophe and you should really watch this documentary" has anyone yet mentioned that we might run out of grazing land? Have you seen the desolation which is Idaho which is mostly grazing land?

OK, now try looking to other countries, for example, Brazil. Upwards of 70% of the deforestation in Brazil is to make room for grazing lands, and we're talking about hundreds of thousands of square kilometers in the last 40 years. Seems like if someone can come up with lab grown meat, they might be able to ease up on their torching the rain forest.

I remember back in the 80's that practically every piece of cheap plastic junk at the local store had "Hecho en Mexico" printed on the bottom. We didn't have a immigration problem back then. Then in the 90's I started noticing that a lot of the cheap plastic stuff had "Made in China" printed on it. I also noted that the southwest states began complaining about illegals at around the same time.

Call me crazy, but we made this problem ourselves. When we pulled our manufacturing out of Mexico and sent it to China the Mexicans had no choice but to come here looking for work. If we could somehow get businesses interested in moving the plants back to Mexico maybe we could cut illegal immigration down.

Or we could throw business men in jail, where we have to support them with tax dollars. My way seems like less of a burden on the tax payer.

Simpler, yes, but the problem is that rotational gravity systems don't scale down all that well. For example, if you're going to approximate Earth gravity, you need a structure about 225 meters away from the hub rotating around 2 revolutions per minute. Anything less than that and you start running into issues with angular and tangential velocity which could cause all sorts of motion sickness and balance issues.

Why is it that every time someone writes an article about procreation in space, they bring up the microgravity question over and over? I get that they're basing their assumptions off of the technology that we use now, but seriously, this stuff isn't going to happen with the technology we use now. It'll be using technology of the future, near or distant. A space station utilizing rotational gravity via centrifugal acceleration can be made to simulate Earth gravity. Slow it down a little and suddenly you have Martian gravity. Slow it down a little more and you've got Lunar gravity. No reason to dip yourself in a gravity well.

Yes, a space station that uses centrifugal acceleration is complicated and would be expensive by today's standards, but again, think about 50 or 75 years in the future. The ISS will be deorbited by then. Will they stop there, or will they make another one? What features and advantages will it have over the ISS? How long with the ISS II be up there? Will they build another one after that? What features will that generation of space station have?

I don't think we'll have to worry about procreation in space for the near future. Right now it's more of a scientific curiosity than an actual need, but that will change if we continue to expand into space. By that point our space technologies will have advanced to the point where it will no longer be a concern.

I just did a quick search and there's a manufacturer selling a desktop 3D printer for $10,000. It uses a different process in the build; more like laying clear tape and cutting it at each layer to produce a model. The next cheapest I could find used the more traditional "goop" like resin and was $15,000. The last time I checked prices about two years ago and they were hovering around $30,000. At this rate you'll probably see models in the $1500-3000 range in about 3-7 years.
The question then is, what do you build with it?

Scientific accuracy is not a requirement of a science fiction story, only that the mechanics of the fantastic elements are attempted to be explained away via science instead of accepting that it is some mystical event (like the result of breaking a religious artifact or something).

Bullshit. Maybe that's what you consider science fiction, but I certainly don't! Hell, by that reasoning Lord of the Rings would be science fiction if they simply called the ring a "personality back-up device". No, I'm sorry, you do not know what you're talking about.

A lot science is very unsound when a SF writer puts in a throw-away sentence or paragraph to explain floating cities, faster-than-light travel, time travel, teleportation, etc. Those things might be possible and sometimes the writer uses scientific journals to justify their tech, but sometimes they just throw in techno-babble.

If the explanation is based on science or scientific hypotheses that have yet to be proven, it's acceptable. It really depends on the execution.

Heck, in Star Trek TNG sometimes they just made up techno babble to explain away the plot device of the week and/or its solution.

Star Trek, while obviously being science fiction, had a problems; they hired writers with absolutely no science back ground at all, but most science fiction television series has this problem. Ignore the episodes that bring down the franchise and you'll enjoy it a lot more (I'm looking at you, Voyager episode "Threshold").

And Star Wars is full of scientific issues, yet they're considered science fiction.

Star Wars IS NOT science fiction. It has never claimed to be science fiction, and never will be.

2012's main plot device was caused by a fantastic event, which the writers tried to explain away.

You keep using this word "fantastic" and yet are seemingly unable to connect it to it's root word "FANTASY". I wonder why that is...

It wasn't like the goal of the film was trying to "fix" the earth via "heavy neutrinos" or some other such nonsense, so it's not even a big deal.

Right. The main reason the sun is destroying the Earth doesn't matter, as long as they don't use some technobabble excuse to fix it.

It was just an explanation of the story's catalyst and antagonist.

The story of 2012 was in "the world is ending in catastrophe, how far would you go to save your estranged family."

I'm not saying I loved the film, but I'm willing to look the other way for scientific flaws.

2012 was a disaster movie. The science they used to explain the disaster was 100% horseshit. I think that's where some people get confused. Since they tried to explain it away with fictional science, it must be science fiction, right? Uh, no.

Science fiction is a fictional story revolving around science or technology.

Fixed that for you.

Doesn't have to be all spaceships and lightsabers to qualify...

I don't understand why this is so hard to understand... Science fiction is fiction based on real science. Light sabers cannot be made in the real world, so Star Wars is not science fiction.

Space ships are really easy to disqualify: If a "space craft" behaves as it would in an atmosphere (banking, swooping, doing barrel rolls and making noise the whole time), it is not science fiction.

The whole Isos concept was lame - like a digital evolution or some garbage nonsense.

I think you mean digital creationism. Flynn's explanation for them was that once the conditions became right they just [magically] appeared. And Flynn, who is supposed to be this genius, goes on to say that they're just algorithms that are really complicated. Yep, that makes sense.
