wow.. ths person has no clue what alaska and siberia is like. Its very pretty, but pretty much fodder for a scifi novel where the bering straight is somewhere near panama in latitude. Its colde then heck up there.. with fierce storms and ice flows that would cause heavy damage to such a structure. ..and how many wild animals are going to want to swim through a tube? This would more then likely just obstruct them more then anything else, with a few stragglers left to go through and starve to death on the other side. The animals need a better solution then this. They could potentially raise the road bed and lower lower the middle regularly in a rolling arc. That way animals, ice and storm surges could flow through, reducing the pressure on the strucutre.

oh give it up .. wikipedia has been proven to be just as accurate a closed source commercial references. Its plenty good for blog comments, theres no expectation of professional level research going on here. Got better info? Post it. As far as the strength goes.. thats only 1 level of measurement here. This steel stuff can be used in harsh environments that would melt or otherwise destroy traditional velcro. That gives it a use right there even if its strength is less.

my question is how the fish remain fed. most fish you would like to have be in these would be predatory like salmon. But it farming them in the open ocean doesnt really do much good if they dont have natural food, since we can already provide them with food that suffices. ..its just not as good as what they get in the wild. It would have to be MUCH bigger..

@technofreakface close but no. Yes you could replace some of what they do. But you could not as you admit go above 800 feet, and they fly at 10s of thousands. They also have sattelite upload. Eventually if not already they will have autonomous capability so if link is lost they can finish out a mission and return to base. The optics they have are not only used for visible light like your camera. They have infrared sights as well.. and really possibley a few other bands as well. Starlight cams? and its not the plane thats 15mil, its the new camera alone.

Drought has been managed for millenia. We've learned to do this since we've been farmers for far longer then we've been machinists. There are unforeseen factors in any energy market; scarcity of fuel (uranium, oil), weather (katrina knocked out almost all gulf of mexico production), geopolitical problems (russia and natural gas), drought (for biofuels). Even more reliable would be wind and solar plants. Even better these can be placed in areas that arent productive for other uses like deserts, and the ocean. We have the options, now we just need the will to put them into action instead of whining about change.
