Turn the Eiffel Tower Green?

A concept to turn the Eiffel Tower into a giant green wall has been proposed as a symbolic statement of "the reconciliation of nature and mankind."The plan calls for 600,000 plants to be attached to the structure using hemp sacks filled with soil as the original brand cialis growth media. An irrigation system comprising 12 tons of tubing would be used to provide water for the plants.

The installation would not be permanent, and would be removed after a few years. But, once in place, the installation would help remove an estimated 87.8 tons of CO2 from the atmosphere.

"Should it not be the duty of engineers to imagine a new future where nature is brought back into the heart of levitra generico the city," said a statement from Ginger, the company behind the proposal. With an estimated cost of nearly 100 million dollars for the project, that's more than a million dollars per ton of CO2. Hardly the buy levitra on line with mastercard most cost effective carbon sequestration, but certainly a visible one.

Climate Change May Be Super-Sizing Birds

Researchers from San Francisco State University and Point Reyes Bird Observatory believe that among the wide array of consequences and adaptations that are occurring with climate change, birds are getting larger and fatter.

The team analyzed data from thousands of birds that were caught and released over the past few decades in the San Francisco Bay and Point Reyes National Seashore area and found that birds, on average, had increased in mass and in wingspan over the past 27 to 40 years.

The researchers believe that climate change could be leading to this super-sizing of the birds in a couple of ways.  One is viagra 50 mg online that birds could be storing more fat to survive the harsher winter storms that have become more common as the world warms.  The other cause may be that climate change is affecting plant growth in a way that is leading to fatter birds.

While this doesn't seem to be a negative development so far, the researchers say these type of discoveries make it necessary to it's great! how can i buy cialis in canada understand why some plants or animals are getting larger and some smaller and what the real impact of those changes could be.

Oyster Mushrooms Can Break Down Diapers in Four Months

Diapers are up there with styrofoam when it comes to things that last forever in landfills.  Surveys of landfills have estimated that it takes hundreds of years for them to break down and when billions are thrown away each year in the U.S. alone, you've got quite a large mess.   A few countries have started diaper recycling plants, but most of the world's dirties get thrown in the trash.

Amazingly, the solution may be in your stir fry.  Alethia Vázquez-Morillas, a scientist at Autonomous Metropolitan University in Mexico City, has found that oyster mushrooms can break down 90 percent of the material in the poop catchers in only two months, and in four months, break them down completely.  And you can still eat the mushrooms, though you may not want to.

Diapers take forever to degrade because their main ingredient is cellulose, which hangs around for quite a while.  The oyster mushrooms have enzymes that break down cellulose, which serves them well when they grow on dead trees or other plant material in the wild.  So, when grown on soiled diapers full of cellulose, the mushrooms just do their job.  Better-than-plastic packaging and now diaper disposal -- is there anything mushrooms can't do?

Dr. Vázquez-Morillas says the mushrooms used in their experiments were still safe to eat because the diapers were treated with steam first to kill any bacteria, though in this particular application, I imagine people would be most interested with the fact that the mushrooms get rid of genuine viagra free shipping diaper waste and not really care whether they were edible afterward.

Festo Demonstrates Artificial Bird


Animal roboticists Festo have come up with the latest in their series of robots which mimic animal locomotion and activity. We've seen a number of compelling demonstrations from them over the past several years, and the latest is certainly impressive: an artificial bird.

The interest in these, besides just looking incredibly cool, is in the development of biomimetic processes. Animals have evolved very efficient methods of locomotion and activity, and these abilities can be applied to automated processes.

SmartBird is an ultralight but powerful flight model with excellent aerodynamic qualities and extreme agility. With SmartBird, Festo has succeeded in deciphering the flight of birds – one of the oldest dreams of enter site humankind.

The video shows just what they have accomplished:

Lesson of Fukushima: No-Nukes or Pro-Nukes?


Along with all the other news surrounding the earthquake and tsunami in Japan, the nuclear power industry is canadian online pharmacy levitra also in the spotlight due to cheapest generic viagra online problems that have arisen at some Japanese reactor facilities in the aftermath of the disaster. It is still a developing situation, and there is far too much that is not known about the results to make any definitive, final statement about the matter. But this is going to trigger an awful lot of debate, and I expect both sides will use this as a case to bolster their arguments.

Let me lay out perspectives from both sides of the issue in the context of the current (and still ongoing) events in Japan and suggest that neither side is going to be able to make an ironclad argument for their side based on this evidence.
