Solar Lily Pads May Spring Up in Scotland

We've already talked about this giant floating solar thermal power plant that the UAE has its eyes on. But now a new kind of solar island is floating down the river of 2 day cialis delivery possibility. Peter Richardson's Solar Lily Pad proposal for the International Design Awards ‘Land and http://medicamentosseguros.com/canadian-pharmacy-viagra Sea’ competition, pulled in first prize and the city of Glasgow seems to be seriously considering making the proposal a reality.

Some would say that there's plenty of space in cities for distributed solar power on roofs. However, this isn't entirely true. Solar thermal plants, which focus the sun's rays to create extreme heat in order to get viagra now turn turbines, cannot be used in cities. Because of the viagra order extreme heat, and the danger of someone stumbling across (or into) one of them, they have to be carefully guarded and separated from passersby.

However, I'm not sure if Richardson wants to use photovoltaics or solar thermal. If he wants to use photovoltaics, then I don't really see the advantage, aside from having large areas of contiguous, in-city solar potential. In America, we find that on the roof of cialis super active the local Wal-Mart...not in our rivers.

I would want some assurance that the River Clyde would not be harmed in any way. I'm not familiar with Scotland's ecology, but it seems pretty obvious that the water temperature would be lowered by this project, potentially impacting the species that live in the river.

The solar pads would be rotated throughout the day, so that the slanted panels could track the sun, and power would be delivered to shore via tethers. Glasgow's city council is considering a small pilot project in conjunction with the buy cheap purchase viagra Glasgow Science Centre. If that ever gets off the ground, you know EcoGeek will let you know.

This is only true when you get near the focal point. The mirror sites themselves are barely over ambient sunlight temperatures, so in fact, you COULD do rooftop mirrors for a central solar thermal site in cities.
The problems with a rooftop model lie mainly in mirror maintenance, land owners, and several other nontechnical issues.

Placing solar panels flat, especially at 55 degrees North, is just not a very effective way to harvest energy.

Look at all that available roof top space in the left hand picture. You can put racks there, get a lot more energy per watt of panel, and not uglify the river.

Just because it's feasible doesn't make it decent. It wouldn't be bad to shade a river, but do it with trees along the bank. Solar belongs on a roof- who are these passersby that are in danger, spiderman?
Roofs are out of the way and out of sight. Often AC units or water towers are up on www.umlauf.de roofs- utilities- so why not solar?
Solar panels on rivers... hahaha.

OK, well MAYBE

These would be perfect for rivers where power plants are located. It would help offset the river heating from the power plants, plug right into existing power grid, and stave off power plant upsizing.

they are pictured as far downstream as the finniestown crane! might make navigation a bit difficult for the PS Waverley which berths there....

Upon closer reading I see that the designers talk about slanted panel installation. That isn't obvious from the illustration. But, cranked up to uk viagra without prescription 55 23? That's a lot of wind resistance - think sailboat.

And they are talking about rotating the canadian cialis 50mg panels on a horizontal plane to track the sun during the day. That's not the path the sun follows most of the year.
