Nice idea, but like electric cars, unpractical and a waste of time. Juts consider leaving a giant structure floating on the sea. It eventually would
be come sea junk as well when the ocean breaks it up.
What makes you think these are unpractical. They are made to withstand oceanic weather and currents. They run at a profit and clean the sea of plastic
What is unpractical is having a mess like this in our oceans and doing nothing about it..

Yes, although I agree that the mess itself is a hassle to deal with, you must not forget that most plastic within our oceans are less than or equal to
about 10mm in length.
Plastic is really good at fragmenting. So what will be the result of that? a machine cannot tell the difference between say, fish eggs, plankton,
algae, and say, another plastic of similar size/color/texture. So, you'd need a scanner, and a pretty elaborate system of scanners, which can tell
the difference and at incredible speeds(keep in mind the rate at which plastic debris is flying into the machine). I do not know of a single scanning
system which can do this.
Number of instruments:
Also consider that there need to be thousands of these in our oceans, especially near our gyres, some of which are larger than some of our continents
and contain heavy concentrations of plastics.
They do run at a profit, but where can you find the manpower and annual funding to maintain your fleet? It takes a lot more than a foundation a 19
year old made.
Also, don't forget the millions of tons of plastics that enter the oceans every year. You cannot keep the oceans clean if you still have the
pollutant faucet running.
I can go on for another hour, but I hope you can now get a better idea of how unpractical it is. And the funny thing is, that this hasn't exactly
been the first cleanup prototype thought up. There have been hundreds in the past made by designers, as well as young prodigal kids... yet all
failures because they could not address some of these very basic issues I've mentioned.
