Can a Synthetic Tree Beat the Real Thing?

We all know that trees are great absorbers of CO2 and the idea of increasing the planting of trees to act as carbon sinks, especially in areas around coal plants and 50 mg viagra other offenders, has been floated around for a while.  But can you make a better tree?  A Columbia University professor thinks so.  He and his company, Global Research Technologies, have created a synthetic tree that they say captures CO2 1,000 times faster than regular trees and without the need for direct sunlight.

The trees feature plastic leaves that trap the CO2 in a chamber.  The gas is then compressed into a liquid and could be used in fuels or fertilizers. The trees collect 1,000 kg of CO2 for every 200 kg it emits and each tree could capture up to 90,000 tons of CO2 per year.

The trees are expensive to produce - about the same as a new car - but their performance could warrant the uk viagra price.  The trees' ability to follow link cialis daily capture CO2 without the aid of sunlight means they could be used in dark, enclosed places where most trees couldn't survive.  They could be used to retrofit coal plants or placed in other areas that are subject to high CO2 emissions to curb the amount reaching the atmosphere.

Making Poop Beautiful: L'Oreal Cosmetics to Run Factory on Cow Waste

We knew that the use of biomass as an energy source was growing, but we didn't know it had gone chic. L'Oreal Cosmetics has announced that they are installing a biomass system at their factory in Libramont, Belgium where they produce many of their brands' haircare products.

The plant plant will feature an anaerobic digestion system that will capture methane from waste that comes from nearby cattle farms. When the system's installation is completed at the end of the summer, methane will be used to generate 85% of the plant's power. Even better is that this is just a single step in the cosmetics giant's plan to cut their factory and warehouse emissions in half by 2015 (based on 2005 levels).

In order to meet their goal, the company will be installing additional onsite renewable energy systems like solar PV and solar thermaland buying more green power from suppliers.

The company also hopes to cut their water use by 30 to 35 percent in the same time frame by using rainwater capture and steam-cleaning technologies.

It's great to see a large beauty company like L'Oreal making substantial commitments to reducing their emissions and water use. Now, to get them to make significant changes in their packaging and cheap viagra canada ingredients...

$6.60 Solar Cooker Wins Financial Times Climate Change Contest

In a beautiful marriage of high function and very low cost, a $6.60 solar cooker called the Kyoto Box won the cialis without prescriptions Financial Times Climate Change Contest and $75,000 from Hewlett-Packard to get the idea into production.

The Kyoto Box is made from insulating two cardboard boxes, one stacked inside the other, with straw or newspaper, placing foil inside the first box and then painting the inside of the second box black. An acrylic cover tops off the design.

The very simple and cheap design is already being produced in Nairobi and the maker Jon Bøhner hopes that it will cut down on the use of firewood for cooking, which would slow deforestation and reduce carbon emissions and indoor pollution throughout Africa. The box can boil 10 liters of water in two hours for cooking or for purifying.

Other simple designs that made it to the final round of the contest include a garlic-based feed supplement that would reduce the methane in cow "emissions" and a wheel cover for delivery trucks that would boost efficiency by decreasing drag.

Soil Lamps: Coming Soon To Lawns Near You

Few people know it, but the soil is teeming with energy in the form of zinc, copper and which is better viagra or cialis iron. Special microbial fuel cells – so-called “Earth batteries” – can transform this energy into electricity.

While solar lawn lamps are great, it is hard to deny the appeal of Dutch designer Marieke Strap’s Soil Lamp. This cool-looking lawn ornament takes a slightly different approach to free trial of viagra soil energy. It takes copper and zinc strips, made out of metals naturally extracted from the soil, and uses them to provide a constant charge to a long-lifetime LED bulb – no bacteria required.

There is one catch – the bulb requires a bit of the best choice buy cialis china water to keep it going, but most people water their lawns anyways, so this is not a huge issue. The lamp earns high marks both for its chic design and for being among the first to explore the buy levitra online pharmacy new field of soil-powered gadgets.

For those interested in picking up one of these cool lamps, it is unfortunately not currently available for order in the U.S. However, as many of Marieke Strap’s products are at retailers worldwide, and given the enthusiastic response, there seems little doubt that these lamps may soon be coming to a lawn near you.

Solar Boxes Save Stricken Bats

It’s nice when two environmental issues can be tackled simultaneously. In this case, those issues are implementing solar technology, and saving a threatened bat population.

Bats in the northeastern parts of Canada and the United States are dying in alarming numbers, and researchers believe that a newly discovered fungus is responsible. The fungus, they say, leads to a condition known as white-nose syndrome. Since white-nose syndrome was first detected in 2006 in New York, the fungus has spread across the border to Ontario and six other states. The fungus has killed hundreds of thousands of bats - as much as 80% of the bat population in some areas. This is of particular concern to cialis no prescription farmers who rely on bats as a way of wow)) buy viagra generic controlling the insect population.

But now with the help of solar cells, the bats may have a way to sleep through this deadly disease. White-nose syndrome is thought to kill the bats by waking them up during their winter hibernation. Bats need to sleep through this period because the insects they need to eat to survive aren't around during the order cialis online canada cold season. When they wake up prematurely, they have nothing to eat and subsequently starve.

Researchers at the University of Winnipeg and Indiana State University theorize that if the bats are kept in a warm place, they will remain in hibernation. They therefore propose using solar powered insulated boxes (that would hold about 200 bats each) to keep the mammals warm – and asleep. The boxes would be powered by car batteries linked to solar cells. Their computer-stimulated model shows that using these boxes could drop mortality rates to as low as eight per cent.
