[mousquet]

You think so? I can't tell. I suppose it will depend on how successful the 'fad' actually is.
It's been tried over here as well, here and there, occasionally, but it's still an oddity. It's not like any huge widespread fashion yet.

If they tried it to a larger scale, pretty sure they'd eventually find some tricks to make it efficient.

I just like the way it looks, so I hope it leads to some sustainable techniques and designs.
