How much uranium and thorium do US coal power plants release a year compared to the kilograms of fuel that have been lost from the malfunctioning reactor?
US coal "The actual average generated power from coal in 2006 was 227.1 GW" (WP) "In 2006, the U.S. consumed 1,026,636,000 short tons (931,349,000 metric tons)" of coal (WP) "Using these data, the releases of radioactive materials per typical plant can be calculated for any year"... "assuming coal contains uranium and thorium concentrations of 1.3 ppm and 3.2 ppm, respectively"... they produce 1210 tons of uranium and 2980 tons of thorium ash each year. Combined and divided by energy produced = 2.1 metric tons of radioactive waste per TWh
So, let me see if I understand what you are saying...
Reduce human population to that which can be sustained without modern power generation
Um, yeah I can't see any issue with billions of people clamoring for limited resources, they will probably all just quietly 'go away' and leave you to a peaceful existence
I find open competition preferable to crony capitalism
If google was to turn a blind eye to uber and grant them that space (or uber to do the same with autonomous vehicles) then a lack of competition would result in stagnation in the market places and less innovation
There is a risk of stagnation if one company becomes so dominant that it eliminates all competition, but we are a long way from that scenario
A data center should have power coming from two different generating plants, redundant on-site power generation and a large battery bank to condition power and fill any gaps. If GT was having manufacturing failures due to the condition of the power supply, then shame on them if they did not build out a similar infrastructure, double shame on Apple if they do not set up their datacenter with clean and redundant power
The Uranium is in the coal, it has been there for millions of years and can you explain why it would magically disappear just because the material is being burned?
FTA "According to the National Council on Radiation Protection and Measurements (NCRP), the average radioactivity per short ton of coal is 17,100 millicuries/4,000,000 tons, or 0.00427 millicuries/ton. This figure can be used to calculate the average expected radioactivity release from coal combustion."
It becomes an issue because we burn 6.14 billion metric tons of coal per year Get it now, minute quantities of a highly radioactive material being carries away by the fly ash that results from the coal being burned, which contains the uranium
The reality is that continued reliance on fossil fuel results in spreading uranium (through coal fly ash) and and CO2 (all fossil fuels) and none of the (so called) clean power sources like wind and solar can provide a steady baseline of energy
Nuclear is the method to get us through the next 50 years without continuing with to increase the production of greenhouse gases, fear mongering over nuclear pollution (uranium from coal fly ash produces more annually than the accidents that you mentions) only drives us deeper into dependence on fossil fuels
Is it s tough choice? Yes, but getting emotional over the scary work 'nuclear' does not make a better decision
The proposal was to make containment of radioactive material and avoiding off-site contamination in an accident a legally binding agreement http://www-ns.iaea.org/downloa... (bottom of page 15)
The actual wording includes the term 'shall', which in a regulatory sense is a pretty absolute statement, it ends with the statement, "these objectives also shall be applied at existing plants"
So, any nuclear operator in the planet would be out of legal compliance if they have any existing nuclear plant that 'may' present a risk of losing containment... Yeah, that would cost a shit-ton of money for the industry to just tread water and would greatly INCREASE the dependence of coal energy in the short to mid term
Everybody seems to ignore that coal also releases Uranium into the atmosphere due to fly ash, this author estimates that annual release to be 1.069 PBq/yr http://nuclearaustralia.blogsp...
This is far beyond estimates that "40 trillion becquerels released into Pacific ocean" had escaped from Fukushima http://www.forbes.com/sites/ti...
Where is the shouting for coal to clean up its act? Nuclear has become the whipping boy for the Green political party and Greenpeace, who in turn seem to be operating well in favor of the coal industry over the interests of the general population
I think that the idea with the screw worm flies was to release so many sterile males that they would breed with the wild females resulting in no young, while this technique will produce young that will die
I suppose that this would have benefits by preventing the female from finding another fertile male to occupy their time

Sure... don't believe me. How about Lee Atwater, the architect of the 'Southern Strategy' and adviser to Nixon and Reagan:
You start out in 1954 by saying, "Nigger, nigger, nigger." By 1968, you can't say "nigger" — that hurts you. Backfires. So you say stuff like forced busing, states' rights and all that stuff. You're getting so abstract now [that] you're talking about cutting taxes, and all these things you're talking about are totally economic things and a byproduct of them is [that] blacks get hurt worse than whites. And subconsciously maybe that is part of it. I'm not saying that. But I'm saying that if it is getting that abstract, and that coded, that we are doing away with the racial problem one way or the other. You follow me — because obviously sitting around saying, "We want to cut this," is much more abstract than even the busing thing, and a hell of a lot more abstract than "Nigger, nigger." -Lee Atwater http://en.wikipedia.org/wiki/D...
Sure, if you go back to the 40s and 50s, you will find that most of the south was Dems and there were even Dem Senators who had been Klan members
Then this little thing call the Civil Rights Movement came along. Some of the former Klansmen (Sen Byrd is a good example) turned their backs on their past and worked to convince people to no longer be associated with that group
By the 70s many people in the South were disillusioned with the Dem party because of the support of civil rights and they were attracted to the Republican party due to the Southern Strategy that was promoted by Nixon and Reagan
Since that time 'States Rights' was the dog whistle to call the racists and klansmen to the GOP and they have gone over in droves, there is no surprise to find that the ranks of the gop are littered with people of that mindset
I was more inclined to think Europe and Japan, but I suppose that having no argument leads you to just shout about them damn commies
That's ok, I guess it would suck to live with an out dated view of the world, particularly when you are trying real hard to ignore that which is plainly obvious
I have found progressives more inclined to ask questions of their critics than conservatives
It has to do with mental makeup, that is to say progressives are a great deal more curious about the world around them, while conservatives already know how everything is and just want to shut up those who disagree with them
With Iridium the approach was to hand ff the transmission between satellites until it was within range of of a ground station to connect to a terrestrial network, or reach another satellite phone, usually one or two hops
They may use a similar approach, although Iridium initially involved the governments in the countries that they maintained gateways in as part of the corporate structure. See Wired story, "The United Nations of Iridium" http://archive.wired.com/wired...
It would make a lot of sense to use the satellite network as the primary routing mechanism and only maintain gateways in geographic locations that Musk has strong political influence in. This would limit political interference from countries that practice censorship and limit money lost to graft and bribery

Pretty cool, when are they going to cover it in tasers and flash-bang launchers and use it to charge hostiles?

good luck with that
Sadly those countries phasing out nuclear power are responding to an emotionally driven political movement
The net outcome is a continued (or increased) reliance on fossil fuels and the CO2 and Uranium that they spread
I live in a desert, we host a very large nuclear power plant
They purify and re-use ground water with many cooling ponds built into their cycle
There is no need for a continuously flowing river in this design
I find open competition preferable to crony capitalism
If google was to turn a blind eye to uber and grant them that space (or uber to do the same with autonomous vehicles) then a lack of competition would result in stagnation in the market places and less innovation
There is a risk of stagnation if one company becomes so dominant that it eliminates all competition, but we are a long way from that scenario
More like 1580's, they hate scientific inquiry questioning the basis for their control structures
Just ask Galileo
A data center should have power coming from two different generating plants, redundant on-site power generation and a large battery bank to condition power and fill any gaps. If GT was having manufacturing failures due to the condition of the power supply, then shame on them if they did not build out a similar infrastructure, double shame on Apple if they do not set up their datacenter with clean and redundant power
I think that you are mistaken

We can easily identify those leaders who fight against secularism as the promoters of religious radicalism and refuse to vote for them
