Comment: Floating-yet-submerged pipeline? (Score 1) 678

Hmm... How about a floating-yet-submerged pipeline?

Water flowing through plastic tubes anchored offshore ... (still submerged mind you - but not laying the seabed).

It could start small -- say two 12 inch pipes, then more, or larger, pipelines added once the concept was proved.

Why does this work? For one thing, eminent-domain, right-of-way issues pretty much go away. And the problem of structural support turns into keeping pipeline sections from _rising_, rather than falling (caused by the natural bouyancy of the pipeline and its contents)

First of all none of the signatories are from Columbia university (i.e. none of the signatories are his colleagues)

Secondly, many of the 'distinguished' signatories are in cahoots with the GMO industry -- including one that was earlier a shill for the tobacco industry. See this post for details:

Haha - you can't see the wood for the trees! (this idiom has a double meaning here)

See the tree? The wood is almost all 'fixed' carbon.

And when it dies, a tree doesn't go 'poof' in a cloud of CO2. Instead, organic matter gets trapped in the ground and new topsoil is created (again, mostly carbon).

Recall a well tended urban 'nature strip' in an older suburb (a century or more)? Typically, the strip tends to 'pops out' from its concrete lining. That's a small version of the same effect.

Instead of having airlines staff the flight deck back up again to previous levels (i.e. reinstating the flight engineer, or adding a third pilot), cue the snake-oil salesmen with the same pitch - irresistible to airlines - which got us into this mess.

Dude : droning on against disbelievers is not helpful to your cause.

Stop the frankenstienish stretched analogies. Some folk here have creative alternatives and are not trolls ; they deserve serious answers.

And yes, they are right about the danger - a sudden gust of wind that lifts a large, twisting, plastic sheet can foul all of a drone's propellors - whether 6 or 16. Which can fly it into a powerline, a soft skull, another drone, or your windshield doing 67 mph.

  You do.not.want to be below one of these when it happens in crowded skies.

Well, Biogen's drug may have its place but it isn't exactly a Speedy Gonzales, and its side-effects include brain swelling.
"Wall Street analysts predict could get the drug to market by 2020"

Also, this research is more elegant - it uses your blood's own cleanup cells to fight the plaques, versus injecting you with a foreign antibody like Biogen's does.

Recent research has tended to show that the Abominable No-Man is being replaced by the Prohibitive Procrastinator. -- C.N. Parkinson
