Sunday 20 March Kommetjie Hall 7pm
The Kommetjie Transition village initiative will be screening Gasland in the Kommetjie Community Hall on Sunday 20 March from 7 pm. There will be a short facilitated discussion afterwards with information on possible next steps that concerned people could take as well some insights into South African geology.
R5 or 5 talents at the door towards Transition events.
The film is 1 hour and 44 minutes long and is a documentary made recently in the USA where Hydraulic fracturing (fracking) as a way of extracting natural gas has been going on for a while despite strong evidence of pollution of groundwater and air and attendant health problems. This is the technology that is being put forward as the way to access gas deposits in the Karoo – much to the anger of farmers and environmentalists.

Upon learning of my intention to come to Cape Town for an internship in sustainability from my home in San Francisco, many of my friends and family were congratulatory and jealous, but quite concerned for my safety as well. “You’re heading to the most dangerous country in the world!” I was warned by more than a few people.
From second-hand reports and stories of people being robbed, shot at, killed, and taken advantage of, I understandably had a vigilant attitude upon my arrival. Upon my first inclusion in a round of “Make the Circle Bigga!” in middle of Long Street, all of these negative perceptions began to erode. While talking with a man and his (?) children at a braai in Nyanga, about Apartheid, forgiveness, and the hopeful future of South Africa, they eroded even further. (more…)

Many of us notice Wind Power as we pass by Wind Turbines spinning eagerly on hill tops or on farms. In the past, wind turbines could regularly be spotted in open rural areas, where there was enough space to incorporate wind power into individual’s livelihood. It is slowly becoming evident that wind power has broken out of its area restrictions and now, wind power products are being utilised in residential areas and contributing as a clean, renewable energy source.
How does wind power work?
When air moves quickly, causing wind, this movement is known as kinetic energy. Wind power mechanisms capture this kinetic energy and convert it into other forms of energy, in this case electricity, which can be used in the home. When looking at the functioning of a common wind power mechanism – wind turbines – the way in which it works is fairly simple. The force of the wind or kinetic energy moves the blades of the turbine which in turn spins a shaft. The shaft is connected to the main source, the generator and this mechanism converts wind power energy into electricity. (more…)
