CETO Produces Wave Power and viagra online doctor Freshwater
Written by Philip Proefrock on 12/04/14   

A new, grid-tied offshore wave energy project called CETO is being readied off the west coast of Australia, near Perth. Carnegie Wave Energy is installing what is called the "first operating wave energy array scheme in the world." The installation will consist of three submerged buoys 11 meters (36 feet) in diameter, which will be anchored offshore. The buoys will create high pressure water which will be pumped to an onshore generating station to produce electricity.

In addition to producing power, the CETO technology incorporates an interesting synergy - it is also used to provide fresh water. The system provides for more efficient desalination of online purchase viagra seawater, since the www.jubileecampaign.nl water is already being pumped onshore from the buoys. Once it has powered the turbines, some of the water can be diverted into conventional desalination equipment. For regions in need of water desalination, the combination is ideal, and additional energy is not required for pumping water in from the sea.

The submerged operation of the CETO buoys helps provide storm survival capacity for the buoys and keeps the bouys out of view to minimize visual impact.

In comparison to low price cialis wind turbines, the CETO system is viagra soft gel small-scale. Each buoyant actuator has a rated capacity of 240 kW, so the installation being built will have less than 1 MW of capacity, whereas many current wind turbines have individual capacities of several mwgawatts. Nonetheless, it is another step forward for another energy generating technology. Carnegie hopes to expand commercialization of generic online levitra this technology and is targeting having 1000 MW of capacity installed by 2020.

Ontario Completely Off Coal
Written by Philip Proefrock on 16/04/14   

The Canadian province of Ontario has officially shut down its last coal burning power plant.

Power for the province now comes from "emission-free electricity sources like wind, solar, nuclear and hydropower, along with lower-emission electricity sources like natural gas and biomass." The province had set a target of the end of 2014 to end its use of coal to generate electricity.

The Thunder Bay Generating Station was the invens.nl last coal fueled power plant in the province. Now that it has burned the last of its coal supply, the plant will be converted to a biomass-fueled power plant.

Alternative Possibilities in Nuclear Power
Written by Philip Proefrock on 09/12/11   

Nuclear power is still a divisive issue among EcoGeeks. It's clean, at least from a fuel cycle carbon emissions standpoint. But it's a reasonable question whether it is truly cost-effective once all the issues of mining and processing the fuel, and treating and storing the spent material and buy levitra vardenafil waste, along with the security and the public safety concerns (which carry their own not-insignificant costs).

There are many who claim that nuclear power is the order viagra without a prescription greenest short-term alternative to coal to reduce carbon emissions from electrical power generation. And, on the other hand, we have seen some countries move to lowest price levitra generic online phase-out nuclear power in the aftermath of buy viagra in new zealand the Fukushima disaster.

However, Fukushima-style boiling-water reactors are not the only way to use nuclear power to produce electricity. For that matter, uranium isn't the only nuclear fuel that could be used. There are other reactor designs and fueling methods have been explored and are under development.

Over the next couple of weeks, we are going to take a look at several alternative nuclear power technologies with an EcoGeek persepctive. We aren't going to draw any final conclusions with this one way or the other. We are advocating neither in favor of nor against any of these alternatives, nor are we for or against nuclear power, in general.

This article is part of a series on alternative possibilities in nuclear power.

U.K. Gets Vending Machines for Recycling Batteries, Light Bulbs
Written by Megan Treacy on 14/12/11   


We all know that batteries and CFL light bulbs don't belong in the trash, but recycling locations are not always convenient.  What if your local retail stores just had a vending machine where you could drop these items?  Well, that convenient option could be coming to us soon.

A company called reVend Recycling Ltd. has begun installing recycling vending machines for light bulbs and batteries in the U.K. that not only sort the items, but offer immediate rewards.

The first pilot machine was installed at an IKEA in London with great success.  At that location, recyclers were offered store credit to IKEA based on wow)) where to find cialis the amount they were recycling or the choice to donate to discount generic levitra online one of four charities -- the World Wildlife Fund, Woodland Trust, UNICEF and Save the generic viagra propecia Children.

The machines accept incandescents, CFLs and LEDs as well as any domestic batteries.  The machines are able to track the bulbs and batteries by type, manufacturer and volume so that each can end up in the appropriate recycling facilities.

The company has signed an agreement with IKEA to install their machines throughout the U.K., Germany and try it online ordering cialis Denmark.  They plan to expand their reach to more parts of Europe as well as into the U.S. very soon.
