Science: Energy: Piezoelectric
Piezo-electric Waterfall   (+7, -5)  [vote for, against]
Natural beauty that supplies power

Piezoelectric plates are placed under a waterfall, generating electricity without destroying the beauty.

Sounds like it would be expensive, underpowered, and difficult to maintain. + For keeping with the spirit of environmentalism!

I don't think DesertFox intention here is "environmentalism" but rather of beauty. There's nothing "environmental" about simply hiding the piezo. I am assuming, the piezos are placed directly on the riverbed.

Riverbed is an ecosystem too, you know.
