tl;dr - Yes, he can, but it's expensive and involves a whole lot of oxidation.
Damascus steel has a noteworthy pattern that is really what Alec is trying to reproduce with the titanium shown in these videos. Here he starts with alternating grades of titanium stacked then forge welds them together.
The steps required to then anneal and machine the titanium billet that he produces are labor-intensive to say the least.
But he does get some cool rings out of the process.
Yes, there's a garbage patch in the center-ish of the Pacific Ocean.
That garbage patch is not anything worth looking at, though. It's an area of higher than average concentration of plastic waste, but it's not something you could walk across or would have trouble boating through. Even a higher density area isn't necessarily a high density area.
As this video reveals, the most common photos attributed as being of the garbage patch are not of the garbage patch. They're of near-shore, highly polluted areas - which might actually be easier to clean up than the garbage patch would be - if we even should clean it up.
The video goes on to explore the sources of plastic pollution (hint - mostly not littering), the value of recycling (limited but worth doing), the role of big corporations in producing plastic waster (suck it, CocaCola), the problems with microplastics (bad, very bad), and the need to reduce more than reuse and recycle.
These kinds of videos are way too easy to find on YouTube.
Plastics bad...we need to use less of them.
...and I write that as I sit beside of plastic bottle of Coke Zero Cherry that I'm drinking today.
