Conglomerate Rock From Mars: (Much) More Precious Than Gold

itzly Re:Go get more? (63 comments)

But will there be a difference in value if the modern rock is also sedimentary ?

Officer Not Charged In Michael Brown Shooting

itzly Re:MOD PARENT RACIST (999 comments)

Statistics have shown that it's much less likely to get shot by the police when you're working on your job, than when you go around robbing convenience stores.

How the World's Agricultural Boom Has Changed CO2 Cycles

itzly Re:So, this raises a few points (180 comments)

First, at what time of year are CO2 levels being measured for use in writing environmental research papers (and dictating policy)?

They just take the yearly average. And the corn isn't adding to (average) CO2 levels, it's just adding a little bit of extra seasonal swings to it.

How the World's Agricultural Boom Has Changed CO2 Cycles

itzly Re:The Science is Settled (180 comments)

So when CO2 data is collected, is the season accounted for?

Obviously. Here's the recent CO2 data: http://www.mongabay.com/images... Note the squiggly monthly line. Also note it only takes a few years before the seasonal low is higher than the previous seasonal high.

How the World's Agricultural Boom Has Changed CO2 Cycles

itzly Re: Gay Sex! Agenda 21. (180 comments)

For some families that may be true. Other families will have different genes, and some of those genes will direct behaviour towards making larger families despite any problems. As long as the extra babies don't die, these genes will grow exponentially.

No, it's not slow, but it will take a few generations. After 4-5 generations, I bet you can already start to see the effect of increasing birth rates.

NASA Offering Contracts To Encourage Asteroid Mining

itzly Re:Investment in our Future (152 comments)

Why not just put the solar panels here on the ground ? Much cheaper and more convenient.

itzly Re: Economics (152 comments)

certain elements sank to the core of the Earth along with the iron, and are therefore very rare

Huh ? Iron is the 4th most abundant element in the Earth's crust with 5% concentration.

NASA Offering Contracts To Encourage Asteroid Mining

itzly Re:Funny as hell (152 comments)

Don't forget that we don't have a need for raw bulk materials in orbit. We want a functional weather satellite for instance. How much would it cost to mine raw asteroid material, carve it into a functional weather satellite, and adjust delta-V to bring it in a Low Earth Orbit ?

Multi-National Crew Reaches Space Station

itzly Re:Same as Columbus (69 comments)

Primitive humans would probably disagree.

They were the ones that did it, using just the tools they made themselves. A little different than for instance the Apollo project that took a big chunk from an entire nation to put a few men on the moon. And that was easy, because they didn't attempt to stay there and try to live off the land.

We'll just kill each other in space. Why do you think human nature would change as soon as they lift off the surface ?

NASA Offering Contracts To Encourage Asteroid Mining

itzly Re:For the novelty! (152 comments)

Correct. But I didn't feel like doing an hour's worth of research for the most accurate number. The Rosetta mission cost EUR 1 billion, and it only managed a one-way 10 year journey of a 100 kg payload on a comet. A mining mission needs to be round-trip, and would easily involve 100 tons of equipment. Cost would run in trillions of dollars easily. Even if you include all platinum group materials, it wouldn't be worth it.

Multiple Manufacturers Push Hydrogen Fuel Cell Cars, But Can They Catch Tesla?

itzly Re:next gen batteries (277 comments)

Based on existing supercharger and battery technology, yes. But it would be foolish to assume that this is the best we can get. As far as supplying the necessary power, there's no problem. All we need is a better battery.

itzly Re:next gen batteries (277 comments)

Agreed, faster charging means that we need better battery (or supercapacitor) technology.

itzly Re:Space Resources (152 comments)

Exactly. There are no people in space, nor is there much use for them. So the water isn't very valuable either.

Multi-National Crew Reaches Space Station

itzly Re:Same as Columbus (69 comments)

The same argument could have been used for staying in Africa.

Poor analogy. It didn't take much resources to leave Africa, and survive outside of it.

Multi-National Crew Reaches Space Station

itzly Re:Same as Columbus (69 comments)

How is this any different than being on Earth?

For starters, we can walk around outside, and find stuff that we can eat and drink just using our bare hands. So, if technology breaks down completely, humans will still be able to survive. That's a little different than anywhere else in the solar system, right ?

Multiplying on Earth can only continue for so long.

Even if all of Mars was habitable, it would only add one quarter additional Earth surface. But it isn't. And the rest of the solar system is even less hospitable than Mars.

And every attempt to mine stuff here on Earth, conducted by the brightest minds will eventually lead to the new ideas and technologies needed to successfully mine stuff here on Earth, which is most likely much more cost effective and useful.
