About time they hit the New York Times:
The company attempting to trademark floatovoltaics can jump into one of those lakes, btw.
...floating solar arrays are becoming more popular, with installations already operating in Australia and the United States, and more planned or under construction.
The growing interest is driven in part by huge growth in the solar market in recent years as the cost of the technology has dropped quickly.
Floating solar arrays — they are often referred to as “floatovoltaics,” a term trademarked by one company — also have advantages over solar plants on land, their proponents say. Renting or buying land is more expensive, and there are fewer regulations for structures built on reservoirs, water treatment ponds and other bodies of water not used for recreation....The floating arrays have other assets. They help keep water from evaporating, making the technology attractive in drought-plagued areas, and restrict algae blooms. And they are more efficient than land-based panels, because water cools the panels.
I tried to push this idea at my old water district five years ago and got nowhere, unfortunately. Now it's an idea whose time has come - in certain places, anyway. Maintenance is trickier, so any place with cheap land and lots of water will have no use for them. OTOH, the hot, water-short areas with expensive land, or problems from algae blooms, or problems from toxics like mercury that become much worse in warm, low-oxygen water are good candidates. All of which describe my water district. Now the local competitor for most-environmental water district has gone ahead with floatovoltaics, so maybe it'll spread.
I still think Lake Nasser behind Aswan Dam is a natural for floatovoltaics, although admittedly it's far from places with power demand. Dryer parts of India could also be great places, and they're experimenting with small systems already.
