Interesting idea.

Romans used water for mining too.

Why do effort when nature does it for you?

Two problems people raise:

Water pressure from 150m+ water column is too much. In the video they talk about dividing the hight slope channel into sections This way leaks will be also smaller.

Putting water inside. This probably is the weaker point of all.

But overall it makes sense. It will be great for a kickstarter to try to replicate it at a small scale.
