	Halfbakery: Hydroelectric Plant
		By selective breeding of salt water tolerant plants it should be possible to get a species which prefers to grow its two kinds of specialised roots in differently polarised water channels.
		As it grows to maturity, the plant contributes to the current flowing through the channels to maintain say a standard 12 volt potential.
		Basically the plant acts as a photovoltaic cell using sunlight to pump electrons from one root to the other.

	Citrus: Federal ruling ends plan for hydroelectric plant
		INGLIS -- Plans for a hydroelectric power plant here were effectively killed Friday when a federal agency denied a rehearing for more time to begin construction and revoked a 1997 licensing exemption.
		The Gainesville company spent more than a decade trying to develop the plant and was fought every step of the way by Inglis residents who said it could lead to flooding and kill fish caught in its spinning turbine.
		Federal policy encouraging the development of small hydroelectric power projects would have made it easier for the plant to be built.
