This idea is already very criticized. French article about it: http://rue89.nouvelobs.com/2014/06/19/boyan-slat-machine-a-n...

Some of the most important innovations and movements in history were 'very criticized'. I'd say they were in good company. On a quasi-related note, here's a project I'm launching soon. It's for innovators: http://diepenniless.com

It was gauche to drop a link there. My bad.

I'm skeptical. Most of the plastics in his/her photos are visible. In the actual gyres, most plastics are microplastics, i.e. particles from cosmetics and clothes washing that have gone down the drain. There's a pinkie fingernail sized piece every couple of cubic metres or so. Definitely not visible. They also harbour life. How to remove the life and give it somewhere to live without upsetting the ecosystem?

Do you have a reference for the main sources of microplastics? My understanding is that they are the result of larger chunks of plastic that just decompose in the oceans. By removing large plastic items we'd make a strong leap forward.

sometimes they are also directly shipment of small plastic pellets in their production form (ie, before being molded into a toy).

If they could only make the email address optional, then I'd consider... there really is no good reason whatsoever to require an email address here for someone who isn't asking for a reward.

I agree but you can use a mailinator account and be done with it.

There's a skeptoid episode about the Pacific Garbage Patch: http://skeptoid.com/episodes/4132 "In 1988, Robert Day, David Shaw, and Steven Ignell submitted a report to NOAA (National Oceanic and Atmospheric Administration) detailing the results of four years of sample collection and analysis of plastic fragments found floating in the Pacific Ocean. They found concentrations highest in the North Pacific Gyre. The auth…

For precision's sake, 450 square meters is nowhere near the size of a football field, be it American Football or Association Football). Both have at least 5000 square meters.

That's assuming most of the macroscopic stuff hasn't already broken down by well before it reaches the gyre.

Use a fake email address.

No one ever said it was a "solid island of plastic" except some uninformed members of the public. You're taking an urban legend to criticize a valid concern. That is like saying hackers can be stopped by banning ski masks because everyone knows a hacker is someone in a ski mask.

Good idea. Is this a scam? Does not look like that. Can this be harmful? Probably not at least in this scale. Ok, here's my money. Test this and let me know if it worked.

In general it is good to be sceptical, but sometimes it can also prevent good things from happening. I think it is better to just throw them some money (or ignore this) than spend time trying to find reasons why this would not work. It's not like we would need to pick either this solution or something else. We can try this, and that and five other ideas and see which one works best.
