And, yet, engineers continue to work on ways to clean up the ocean gyres. In days gone by, no one thought going to the Moon, let alone Mars, would ever be possible. Decades later, who would have thought a palm-sized electronic device would hold more power than the supercomputer at Rice University ...

This may be a solution, but I think it's needs to be put into a more robust decision framework including clarity on the problem being solved and alternatives. It also calls for deep issue raising and evaluation across both the full range of issue space including technical, operational, environmental, ...

The idea is very simple in concept – but no doubt daringly novel. Hope it will work, although as far as the material is concerned, the efficacy of polypropylene with other reinforcements was questioned ( e.g. by Konrad Mech). But seems to be working on a small scale in Germany (As Bevin pointed out)! ...

I think we should layout the various alternatives, determine the extraneous constraints & consequences and t select that ones that give us the biggest bang for the buck.  This is the standard approach to engineering problems.  in this case what are you going to do the covering deteriorates and ...

There are 3 possible issues with this approach. Polypropylene is a hydrocarbon product and ironically requires oil extraction and refining to produce. Blankets like this would have to be UV stabilized.  The best UV stabilizer is carbon black which would absorb solar energy. If not UV stabilized, ...

Dear Bevin, as I was reading your article, I had the same thought about plastic. Wouldn't it be wonderful to harvest the plastic from the ocean gyres to make blankets?!
