A section of faulty pipeline.

Property owners who watched with disgust and fear as TransCanada contractors ripped up their land to lay the southern leg of the Keystone XL pipeline are being treated to a repeat performance.

The pipeline isn’t even in service yet, but already TransCanada is digging up stretches of faulty piping and replacing them, raising fresh safety fears. The pipeline is intended to link up with the Keystone XL northern leg — which is still waiting for approval from the Obama administration — and then carry tar-sands oil down to refineries in Texas.

From a Public Citizen press release:

Dozens of anomalies, including dents and welds, reportedly have been identified along a 60-mile stretch of the southern segment of the Keystone XL pipeline, north of the Sabine River in Texas.

In the past two weeks, landowners have observed TransCanada and its vendor, Michels, digging up the buried southern segment of the Keystone XL pipeline on their properties and those of neighbors in the vicinity of Winnsboro, Texas. Some of the new pipeline has been in the ground on some owners’ land for almost six months. It is believed that problems identified on this section of the Keystone XL route must have triggered the current digging, raising questions from landowners about the safety of the pipeline and the risk to personal property and water supplies.

Landowners are concerned that this digging is indicative of faulty pipeline along the route that could potentially leak and threaten water supplies, and have requested TransCanada and the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration to provide more information about the work.

From Inside Climate News:

Photos taken by residents show wooden stakes in the ground labeled “weld” or “anomaly.”

Mohammad Najafi, a civil engineering professor at the University of Texas at Arlington and editor-in-chief of the Journal of Pipeline Systems Engineering and Practice, said an anomaly “relates to something unusual” on the pipeline that could potentially cause a problem.

The presence of 40 anomalies over a few dozen miles is “very unusual” and “shows that something is wrong,” he said. “That’s not a good sign … it doesn’t necessarily mean it’s dangerous, but it means [TransCanada] may have missed something.”

TransCanada spokesman Shawn Howard said the Keystone XL is being fixed “out of an abundance of caution” to ensure that it operates at a “much higher degree of design and safety than any other pipeline.”

Public Citizen Texas produced the following video about the unexpected and unsettling bout of pipeline repair:

Artificial Brains May Be the Best Way to Control Electricity

Nothing humans have created beats the brain at the type of complex problem-solving that involves logic, creativity and making connections. And to one group of researchers, the brain, with its ability to “monitor, forecast, plan, learn and make decisions,” seemed the obvious choice for controlling a complicated system for producing and meting out energy supplies. They attempted to put the cells of a rodent’s brain to the complicated task of managing the country’s power supply, and the results of their experiments, they hope, could pave the way for smarter control of the energy grid, LiveScience writes.

To begin, the team of neuroscientists and engineers grew rodent neurons in the lab:

The technique involves growing neurons in a dish containing a grid of electrodes that can both stimulate and record activity. The electrodes connect the neuronal network to a computer, allowing two-way communication between the living and the electronic components.

They hoped to capture the physical responses of the neurons and translate them into mathematical equations, as they tinkered with voltage and speed signals sent across a simulated power grid. If successful, LiveScience writes, they could use these data as the basis for a brain-inspired computer code for controlling the power grid, which will likely become ever more complex as energy from renewable sources, including solar and wind, come online.

So far, the researchers report that they managed to teach their neural system, called the Brain2Grid, to respond to complex data, Discover News writes, the first step for designing a super-intelligent—but purely artificial—means for controlling the future grid.

Despite what most guys think, hormones are just as important for them as they are for women. However, by the age of 30, the typical man’s testosterone levels start to drop 1 percent each year, which can result in less muscle, less energy, more fat, and a flagging sex drive. After a decade of research, health and fitness expert John Romaniello has discovered safe, natural, and highly effective ways to produce more testosterone and bring about remarkable changes in a man’s body. His program is based on cutting-edge science that counters the online “noise” about male hormones. In Man 2.0 Engineering the Alpha , Romaniello and Adam Bornstein, editorial director of Livestrong.com, present a powerful way to improve physical, emotional, sexual, and psychological health for men. From research in Olympic labs to real-life results with their clients, they are reinventing masculinity and showing every man how to be who he wants to be.

How To Go Green With Your Energy

You might think it takes a lot of specialized knowledge about technology to use green energy technology. However, you don’t need to become a technology expert to use green energy technology in your home. You just need some basic information about how to use this technology to save energy. Read on for some tips.

Purchasing green energy is something that many people do not even think about. However, purchasing green energy not only helps promote the security of energy in the future, but it also helps reduce pollution. Purchase green energy in an effort to modernize your home and your way of thinking when it comes to energy efficiency.

Always have a backup power source for a wind generation system. Your system needs to be able to account for low-wind days. This backup could be another type of renewable source, such as a battery system powered by solar, or a diesel generator. Another option is to have the home plugged into the utility power grid.

Windmills are capable of creating electrical energy without polluting anything. Purchasing your own windmill can be expensive, and there may be restrictions on putting one up where you live. If you can install your own windmill, you will be able to sell excess electricity to your local power company and recoup some of your costs.

Warm-air registers, radiators, and baseboard heaters need cleaning at least once per year. It is best to clean these at the beginning of the cold season so they are ready to work at top efficiency once the weather turns cold. Clean heating units will distribute the heated energy evenly.

Install toilets that have the WaterSense label. These toilets use around 30% less water, and are have been tested for maximum efficiency and performance. The average toilet is flushed around five times a day, and with these WaterSense labeled toilets, about 4,000 gallons of water can be saved a year.

Plug your computer, televisions, stereos, and other electrical equipment into power bars. When you are not using these things, turn the power bar off entirely. This will reduce your energy consumption significantly as these items will use electricity even when they are not turned on if they are plugged directly into a wall.

A good energy saving tip for the kitchen is to cut any food you are cooking into smaller pieces. This greatly reduces the time necessary to cook the item which means your appliances will not be running as long. This serves to both cut the amount of energy needed as well as reduce the amount of your electric bill.

You can reduce your monthly energy bills by air-sealing. This means sealing off openings in your home where hot and cool air can either escape or get inside the home. Places to seal include windows, doors, gaps around attic access hatches and pull-down stairs. Look for anyplace where you can find gaps that allow heat or cool air to escape!

After reading this article, you can see that green energy technology isn’t so hard to implement. You just need some basic knowledge like this to help you. Use the tips from this article to help you make your home more green, so that you can save energy.

To build a residence you may use certain strategies just like Composite metal decking

This Town Was Almost Blown Off the Map

Now it’s back, and super green. dmbernasconi/Flickr If I were to tell you this is a story about a tornado in Kansas, it would probably bring to mind a certain doe-eyed girl and her little dog. Well, sometimes tornadoes transport girls and their adorable pets to magical lands. Other times they level entire towns. That is what happened the night of May 4, 2007, when an EF-5 tornado (for non-Kansans, that’s a really freaking big — the biggest, in fact) nearly two miles wide hit the town of Greensburg, a farming community in south-central Kansas. Almost all of the 1,383 residents lost their homes, nine died, and the town was left looking like this: To keep reading, click here.

Earth-Cooling Schemes Need Global Sign-Off, Researchers Say

green4us

World’s most vulnerable people need protection from huge and unintended impacts of radical geoengineering projects. NASA Goddard Photo and Video/Flickr Controversial geoengineering projects that may be used to cool the planet must be approved by world governments to reduce the danger of catastrophic accidents, British scientists said. Met Office researchers have called for global oversight of the radical schemes after studies showed they could have huge and unintended impacts on some of the world’s most vulnerable people. The dangers arose in projects that cooled the planet unevenly. In some cases these caused devastating droughts across Africa; in others they increased rainfall in the region but left huge areas of Brazil parched. “The massive complexities associated with geoengineering, and the potential for winners and losers, means that some form of global governance is essential,” said Jim Haywood at the Met Office’s Hadley Centre in Exeter.

Department of Energy announces millions in grants to offshore wind projects

Department of Energy announces millions in grants to offshore wind projects

There is some good news in the wind industry: The federal government has announced a large investment in offshore wind.

From the New York Times’ Green blog:

The federal government is stepping up its efforts to kick-start the offshore wind industry by awarding $28 million in grants to seven projects that are developing varying kinds of power-generation technology.

The Department of Energy said Wednesday that each developer would receive up to $4 million to complete the engineering, design and permitting phases of their projects in six states. Three of the seven will then be selected to receive up to $47 million over four years, subject to Congressional appropriations, for construction and installation, with the aim of having them begin commercial operation by 2017. So far, no offshore wind farm is operating in American waters.

The Department of Energy also has a surprisingly cool map of the grant recipients. (You may need to zoom out.)

DoE is clearly bullish on offshore wind energy. In its description of the opportunity, it notes:

Offshore wind resources are abundant, stronger, and blow more consistently than land-based wind resources. Data on the resource potential suggest more than 4,000,000 megawatts (MW) could be accessed in state and federal waters along the coasts of the United States and the Great Lakes, approximately four times the combined generating capacity of all U.S. electric power plants.

As the Sierra Club noted in a press release:

Wind energy in the US has seen incredible growth under the Obama administration. Wind power has doubled over the past four years employing more than 75,000 Americans, and the industry hit a historic milestone this summer when it reached 50 GW of installed wind capacity in the United States. Offshore wind could provide more than 4,000 GW of clean, domestic electricity and a U.S. offshore wind industry could support up to 200,000 jobs across the country by 2030.

We’d recommend against driving out to the shore to charge your phone just yet. Offshore wind still faces staunch opposition from fossil fuel advocates in particular. And the process of grant-making by the Department of Energy is of course what brought us the long-running and completely useless Solyndra investigation.

The investment, though, is a significant boost to offshore wind. And the wind industry can use all the good news it can get.

Philip Bump writes about the news for Gristmill. He also uses Twitter a whole lot.
