As we leave the solar system radiation should decrease the further out we go.

Just no.

You are confusing Solar radiation with cosmic radiation... and they are largely very different things.

The "solar wind" is largely photons and other, relatively low-energy charged particles from the sun. (Note the word "relatively".) Which is GOOD for us here on Earth. Because cosmic radiation has a much larger component of HIGH energy particles. The solar wind interacts with Earth's magnetic fields in such a way as to shield it from the cosmic high-energy particles.

But it's the cosmic high-energy particles that penetrate far enough into the atmosphere to ionize particles of matter, which form nuclei around which clouds form. So... high sunspot activity generally means fewer clouds, which in turn means it gets hotter. When "solar storm" activity is low, more cosmic rays leak in, forming more clouds, cooling the weather.

Unfortunately, it is these high-energy particles which require the most shielding. And in general, cells are more prone to damage than radiation-hardened silicon chips.

Again total crock of shit. Australian Uranium export laws Not only is mining totally and strictly regulated (no matter who the hell owns the mine, they can not even stick a shovel into the ground until approval is gained from local, state and federal government), it can only be sold to countries the Australian government has specific agreements with and is restricted to energy use only

100% irrelevant to the topic I was discussing, which was ownership of U.S. uranium interests by Russia. Not only is Australia a completely different continent, its politics are also completely different. Similar in some ways, but definitely not the same.

It is the US government that is seeking to directly control the mining and export of 'AUSTRALIAN' Uranium because 31% of worlds resource and Australia already exports Uranium to China and the US. There are a whole bunch of Uranium resources yet to be touched.

Again, completely irrelevant to the topic under discussion. If I lived in Australia, I'd object to sales to China OR the U.S.... but especially China.

Nuclear is not the only solution, nor is it particularly attractive when solar can achieve the same goals, without the side effects.

How do you claim absence of side effects?

Solar farms are already observed to fry birds and blind pilots. Not to mention the huge amount of landscape they consume. And in high latitudes, not only to they take up even more (and more ecologically sensitive) area, they aren't even usable a good part of the year. In my area, they don't even come close to competing with other sources for cost.

This has been studied and the result was that there is a localized heating effect in a small area immediately downwind of the wind turbine which is rapidly lost in the noise of the already-chaotic system in precisely the same way that the butterfly effect is bullshit â" if an entertaining thought exercise.

This causes me to think you haven't understood what the Butterfly Effect actually is. It says that slight differences in the initial conditions of some nonlinear systems can have a profound effect on later outcome. It doesn't apply to all chaotic systems by any means, nor does it necessarily mean a persistent change... just a big one. Nor, just off-hand, would it seem to apply to your windmill example at all.

You might be interested to know that the Butterfly Effect has made a profound contribution to weather and climate modeling. Without it, we would not know even the relatively small amount that we do know.

The name "Butterfly Effect" was intended as an analogy to how it works... it isn't to be taken literally. But it does work, and is observed in the real world. If you doubt that, I strongly suggest you avoid flying in a modern jet.

If they don't know what they are doing, then why are they the leaders?

I disagree with others here. If they say they don't know if their organization has the talent to succeed, then indeed they don't know what they're doing.

Especially those who think their IT dept. is incompetent. What that means is (A) they are wrong, or (B) they are right... which in turn says they made bad hiring decisions and should clean house.

DC has very rapid power loss over any kind of distance.

No it doesn't. Losses are related to current, not AC vs. DC. A higher current in the same sized conductor equates to higher loss. You can get around this by raising the voltage (traditionally easier with AC), thus transferring the same amount of energy with less current, or you can increase the size of the conductor. DC can actually transfer more energy than AC on a similar sized conductor because it doesn't have to deal with skin effect.

I could link all of these terms to applicable articles for you but I'm feeling lazy and this is all common knowledge stuff anyway.

Bomb squads don't "investigate" items that might be bombs. They safely dispose of them. Are you seriously going to value a $30 pressure cooker over someone's life? If the authorities were wrong they should (and usually do, FYI) reimburse the property owner. No piece of property is worth taking a chance on someone's life.

If you want fair competition, you have to do it under the same rules as everyone else.

And fair rules would be that any driver that meets some objective criteria relevant to driving (vehicle inspection, insurance, licensure, ...) can operate a taxi and obey the same rules. Unfair rules would be something like "the first 1000 people to sign up" can operate a taxi and everyone else can sod off.

Not every rule or regulation is an evil plot to suppress the entrepreneurial spirit.
Not every rule or regulation is justified in protecting consumers or the public.

In this case, the consumer-protection part of the laws are undoubtedly the former while the arbitrary limitations on the number of licenses seem very likely to be the latter.

This has nothing to do with fair competition, or protecting entrenched players. This is about governments having the authority to pass laws, and whiny idiots claiming they don't want laws.

Of course they have authority to pass laws. And people have the right to complain when the laws go beyond protecting consumers into protecting a racket. Not every law is foolish or an imposition or liberty but as the same time some are giveaways to special interests.

Yep, you've hit it on the head: the fashion world heavily depends on hyperspecific brands. A parent company may own an immense number of outlet identities that aim to cater to a specific submarket. Hot Topic is a good parent company for ThinkGeek because their model is already built around faddish, meme-driven trends (as you said), but the two target audiences have little enough overlap that this will be a substantial diversification to their marketing reach.

Perhaps the municipal governments having control of the infrastructure

My municipal government can't even keep the streets in good shape. Ever seen this meme? It's an accurate reflection of the condition of the roadways here. They don't even have the hard freeze excuse that my municipality in the northeast had. You want them running the last mile? Thanks, but no thanks.

There's probably merit to someone owning the last mile infrastructure and leasing it out to ISPs; there's definitely merit to separating the TV side of the house from the ISP side.
