Doomed Clean Energy Project Restored

Interesting story about how one failed clean energy product brought life to a new one, two decades later.  Here's an excerpt:

Two decades ago, a section of the Amazon rainforest was flooded for a dam that currently produces little electricity. Engineers now see that artificial lake as an ideal surface for floating solar panels.

Critics have blasted the Balbina dam, located near the equator some 200 kilometers (125 miles) north of the Amazonian city of Manaus, as an environmental crime.

The dam, which flooded about 2,400 square kilometers (930 square miles) of rainforest, was ordered built at great expense during Brazil's 1964-1985 military regime. The artificial lake is so vast that from the dam's wall, the horizon barely comes into view.

But when it comes to generating electricity, the dam is a bust: the Balbina hydroelectric plant, inaugurated in 1989 after a decade of work, currently produces a mere fifth of its maximum output of 250 megawatts.
