No not really, I am just stating that their goal is to reduce the costs that come from placing these on land, but are instead going to create a whole other category of issues.

Plus, the article said they want to place them above water surfaces that come from industrial plants, so who knows what kind of crap you will have to protect the cells from.

Wouldnt you face an inefficiency problem with the solar panels laying flat on the water? They upped the panel's efficiency over normal panels, but all of those are aiming more or less directly at the sun's position in the sky. If you put these on the equator, there would be a few days a year the panels were pointed directly at the sun, otherwise the earth's tilt would start to effect the solar output. In northern latitudes it'd be worse, since in winter you're looking at sun angles of 20 degrees or less (setting sun). I know with my homemade panels I can register .2amp loss just by moving it a couple degrees away. Over a large array with huge angles they're going to face some big losses....

Yup, it just doesn't make sense, it isn't like every continent doesn't have some area that people want nothing to do with. I was stationed in 29 palms, CA and there is plenty of land that no one cares about. I remember they planted cacti to spruce the place up and even those didn't survive.

1. Who says they have to lie flat on the water's surface? Floating booms with an adjustable frame wouldn't be difficult to fabricate.

2. Corrosion: Simply apply a clear laminate skin over the frames, besides, it's not seawater we're talking about here. Normal cells will last 30 years sitting on the roof of a house, exposed to the elements. Maintainance consists of keeping them from being covered in pollen, grime, treesap, etc. Not a difficult issue to overcome.

Fresh water lakes= minimal corrosion.
Who ever said a little shade kills fish?
Look at Docks, which actually attract fish. As long as they space them in like rows, then it will be beneficial to the Ecosystem. Bass fisherman will love this if done in the USA.

It's an interesting idea to say the least. Use the space to make energy and store liquid waste, neat.

What happens when the water evaporates? Wouldn't they need a steady stream of water to keep the levels sufficient?

Rather than build outward...they should build solar arrays upward.

We need to implement this more so than anything else, since the large majority of large cities are near the ocean (or on a river) it seems the logical choice.

These are industrial water basins, they exist for a purpose, so this shouldn't be a problem.

Building upward is great - oh, wait; now you are casting a nice long shadow, except at the noon hour, obscuring the other banks of solar cells.
