How To Prepare For the Apocalypse With Vegetables – My Sun Ray Garden Design Will Save Me

Ah yes, the Apocalypse awaits us at the end of 2012. At least this is what the Mayan calendar tells us and face it, this year’s local Chicago weather has been a tad bit Biblical and apocalyptic; 80 degrSun ray vegetable garden design in Shawna Coronado’s front lawn ees in February, frost in June, extreme drought May through July, showers and cool weather in August. We are expecting it to rain frogs and the rivers to turn to blood in September – I’ll let you know how that goes. My solution to survive the apocalypse is to plant a front lawn vegetable garden. I mean, hell, if an apocalypse DOES come to suburbia, I want to make sure I am prepared with organic, healthy veggies to make dinner complete.

THE LIVING SOIL – www.simplesite.com/Sustainable-Gardener

All plants from the smallest to the largest trees are boundary creatures that connect the Earth and the Sky, Papatuanuku and Ranginui, Mother Earth and Father Heavens. They have their roots in the good earth and their branches and leaves stretched to the sky. Plants get nutrition from both above and below. They are not separate from the rest of creation. Through the miracle of photosynthesis they receive carbon dioxide from the air plus light from the sun to provide energy to form of sugars and starches and their building blocks in the form of cellulous to make their cells and give them structure, as well as receiving essential life giving water from the heavens. From the soil they obtain a huge range of nutrients, including Nitrogen, which they combine with Carbon and Oxygen from Carbon Dioxide and Hydrogen from water, to make their proteins. Plants also provide us and all the animals on earth, with life giving Oxygen.

Community Food Growers Network | connect, cooperate, support, defend, lobby and celebrate

‘No to GM crops, Yes to Food Sovereignty’ – Public teach-ins on April 17th.

The community food growers network invites you to a day of public events exploring why Genetically Modified (GM) crops pose a threat to sustainable food production, what the GM industry is doing here in Britain, and how we as ordinary people can support alternative, sustainable and socially just food systems.

The teach-ins will be held in Walthamstow, Chingford and Brixton on the 17th of April and will provide a space for people with little or no knowledge of the issues surrounding the industrial genetic modifications of food crops (and other forms of life such as insects) to talk to experienced campaigners, concerned food growers and people passionate about supporting local food. Combining films, presentations, practical gardening and discussions this will be a day of grassroots popular education. All events are free of charge and open to everyone.

These events are organised in solidarity with small scale producers all over the world who come together to take collective actions on April 17th.

GM food is back on the British Government’s agenda. This year marks the first open air trial of GM wheat ever to be held in the UK, and a big step towards the commercial cultivation of GM crops in Britain. As community food growers we work to create healthy and sustainable food systems for the benefit of local communities, their economies and environments. We believe that the open air testing and commercial growing of GM crops is a serious threat to sustainable food production. To communicate the urgency and necessity of a strong response from civil society we invite you to our teach-ins on the 17th of April.

What’s on in Waltham Forest – North East London?

‘No to GM crops’ Special evening of discussion, teach-in and film in Walthamstow:

7-8pm -Presentations on the current situation in Britain, how GM crops threaten sustainable food production, and what we can do about it. This will include open discussion – a chance to learn why and how people oppose gm crops.

8-8:30 – Soup by donations, and time for further discussions.

8:30-11 – Film followed by discussion. We will show the 2004 documentary ‘The Future of Food’, a pioneering film which explores the key agricultural, social and political issues surrounding the industrialisation of agriculture and genetic engineering. The film is based in the USA, one of the original testing grounds for the GM industry, and documents the effects that the development of the industry has had on farmers and consumers there as well as highlighting the ways in which GM was globalised.

* Sadly we have been unable to source a copy of ‘Raising Resistance’ because it has not been released for distribution yet. We hope to be able to screen the film after its release in December 2012, stay in touch for details!

New Storage Projects Turns CO2 into Stone ››Scientific American

Iceland is experimenting with pumping carbon dioxide underground and converting it into rock

 | March 5, 2012 

In a new experiment, Iceland is looking to replace its smokestacks with well injectors to permanently sequester its carbon dioxide emissions.

Researchers are now pumping CO2 underground in a process that will convert the greenhouse gas into rock. This technique may be a model for other power plants and factories to control their emissions, creating a climate change solution literally set in stone.

“Carbon dioxide capture and storage is important because we depend on fossil fuels, and we will depend on fossil fuels for the next 50 to 100 years,” said Juerg Matter, a professor of geochemistry at Columbia University.

“This is bad news for global climate change, especially greenhouse gases in the atmosphere. In terms of climate change, we have to decarbonize our energy infrastructure,” he added.

The CarbFix pilot program aims to resolve this problem by capturing carbon dioxide from the Hellisheiði Power Station, Iceland’s largest geothermal heat and energy facility and the second-largest in the world.

The 300-megawatt plant taps heat and gas pockets up to 1.2 miles below the surface to drive seven turbines. In the process, Hellisheiði releases steam, which makes up roughly 99.5 percent of its emissions. The rest is mostly carbon dioxide, along with small amounts of hydrogen sulfide, argon and methane.

Matter, who works with the program, said CarbFix is the first system that injects carbon dioxide into basalt, a form of volcanic rock. “The capacity of these rocks, the storage capacity, could be very large,” he said.

Going from acid to rock
Waste carbon dioxide is first separated from steam and then dissolved in water, forming carbonic acid. The solution is then pumped 550 yards underground into a basalt formation, where the acidity leaches elements like calcium and magnesium from the surrounding rocks. Over time, the solution flows through the basalt formation and these elements recombine to form minerals like limestone.

Iceland makes an ideal test site because the ground beneath the island nation is 90 percent basalt, which is formed by volcanic activity. The country also generates most of its electricity from geothermal sources.

However, CarbFix is not without its challenges. The project’s current phase injects carbon dioxide from a nearby geothermal well instead of the generation plant. Though the project started in 2007, the team only started injecting the well in January and will begin to inject from the geothermal plant itself in April.

“We assumed that the main difficult part of the experiment would be injecting the gas. Instead, we are delayed by the gas separation stage,” explained Edda Aradóttir, the project manager for CarbFix. “It has turned out to be a much more complex task than we thought.”

Separation anxiety
The hydrogen sulfide proved very troublesome because it corroded the hardware and formed compounds that hampered the processing equipment when it was separated from the steam. The current phase injects only carbon dioxide, while the next phase will also inject hydrogen sulfide into the basalt.

Other issues included developing new instruments and techniques to monitor rock formations deep underground, said Aradóttir. The team also had to engineer a system to transport the carbon dioxide from the sources to the injection well.

The whole process is also resource-intensive, requiring large amounts of water and electricity. The carbon dioxide may also take anywhere from a few months to a few years to be converted fully to stone. “This kind of experiment is very expensive,” admitted Aradóttir. “We’re not at the commercial stage yet.”

Still, the idea has immense potential. Basalt formations are found in many parts of the world, and the CarbFix site can store billions of tons of carbon dioxide, Matter said. Unlike other forms of carbon storage, waste gases can be converted to stone at relatively shallow depths, the leakage risk is minimal and the results are permanent.

In addition, CarbFix is already showing results. Matter observed that the acidic solution is being neutralized underground, indicating that the rock-forming reaction is taking place. “If it’s mineralized within a human lifetime, then we know we are on a successful pathway,” he said. As the technology improves and the costs come down, Matter thinks sequestering carbon dioxide in basalt could become a viable strategy for controlling greenhouse gas emissions.

Proof of permanent storage could ease some of carbon capture’s commercial problems. One of them is obtaining insurance coverage, because insurers are concerned about the long-term financial risks of storing carbon dioxide in a gaseous or liquid form underground, which include the possibility of leakage.

Sarkozy will Akw-Laufzeiten auf mehr als 40 Jahre verlängern <<finanzen.net

PARIS (dpa-AFX) – Der französische Präsident Nicolas Sarkozy will die Laufzeiten der 58 Atomreaktoren im Lande über die vorgesehenen 40 Jahre hinaus verlängern. “Die Entscheidung ist gefallen”, sagte Industrieminister Eric Besson am Sonntag. Allerdings muss die Atomaufsicht zustimmen.

Frankreich bezieht drei Viertel seines Stroms aus Akw und Sarkozy ist ein harter Verfechter der Kernkraft. Sein Herausforderer bei der Präsidentenwahl im Mai, der Sozialist François Hollande, will den Anteil der Kernkraft dagegen bis 2025 auf 50 Prozent drücken.
In den kommenden zehn Jahren erreichen 22 Reaktoren ihre geplante Lebensdauer von 40 Jahren. Um sie zu ersetzen, wären elf Meiler des neuen Typs Europäischer Druckwasserreaktor (EPR) nötig, von dem allerdings noch keiner funktioniert: Die ersten EPR werden gerade in Finnland und Frankreich gebaut. Der staatliche Energiekonzern Electricite de France (EdF) will die Laufzeiten auf 60 Jahre verlängern. Dies würde pro Reaktor 680 bis 860 Millionen Euro kosten, ein Bruchteil der Milliardenkosten eines EPR. Dabei spielt auch eine Rolle, dass der Bau des EPR sich nicht nur als unerwartet teuer, sondern auch als unkalkulierbar langwierig und schwierig erwiesen hat./cbf/DP/nmu
