The Japanese text with the YT video says this is a part of the "old national highway No. 222", near Miyakojono in Miyazaki Prefecture. (Google Translate is your friend.)
It's not surprising either. The mountains of Japan are full of old roads and trails like this. When a landslide destroys a large piece of a road, they just build a new one elsewhere.
(Don't bother looking this up on English Wikipedia, the articles about the Japanese road system are poorly written and lacking in references. BTW, did you know that all the major divided highways in Japan are toll roads? They're expensive, too.)
This would be a good site, except for the fools slapping their watermark right in the middle of each photo, helping to obscure some of the old ads. Genius!
OTEC is a very old idea. There are actual working power plants that use it to generate electricity, usually on isolated islands where petroleum fuel is costly.
The scheme in this article is workable, but I would bet that using it to push a large ship would require a large number of floats. I doubt it would be practical for most commercial shipping.
Wikipedia actually has good information on asparagus smell in urine:
Certain compounds in asparagus are metabolized giving urine a distinctive smell due to various sulfur-containing degradation products, including various thiols, thioesters, and ammonia.[29]
The volatile organic compounds responsible for the smell are identified as:[30][31]
Subjectively, the first two are the most pungent, while the last two (sulfur-oxidized) give a sweet aroma. A mixture of these compounds form a "reconstituted asparagus urine" odor. This was first investigated in 1891 by Marceli Nencki, who attributed the smell to methanethiol.[32] These compounds originate in the asparagus as asparagusic acid and its derivatives, as these are the only sulfur-containing compounds unique to asparagus. As these are more present in young asparagus, this accords with the observation that the smell is more pronounced after eating young asparagus. The biological mechanism for the production of these compounds is less clear.[citation needed]
The onset of the asparagus urine smell is remarkably rapid. It has been estimated to start within 15–30 minutes of ingestion.[33][34]

Plus, it seems that camcorders exist so that clumsy people will drop them, forcing the purchase of new camcorders. Growth industry!
