The Keystone Principle: Stop making it worse

2013-02-16 22:12:00| Climate Ark Climate Change & Global Warming Newsfeed

Grist: The big President`s Day rally on the National Mall is more than a Keystone pipeline protest. It`s a statement of principle for climate action. After a year of unprecedented destruction due to weather extremes, the climate fight is no longer just about impacts in the future. Its about physical and moral consequences, now. And Keystone isn`t simply a pipeline in the sand for the swelling national climate movement. Its a moral referendum on our willingness to do the simplest thing we must do to...

Astrium brings space to you. Number 1 in Europe and number 3 worldwide, Astrium employs over 17,000 men and women mainly based in five European countries France, Germany, the UK, Spain and the Netherlands. Our technical excellence and extensive prime contractorship experience extend across all sectors of the space business launch vehicles, manned space activities, satellite systems and related services. A Propulsion Design Engineer Vacancy has arisen with Astrium in Stevenage. The propulsion department is responsible for the RD, conception, design, analysis, test planning, launch and inorbit support of spacecraft propulsion systems. Typically components such as engines, valves and tanks are procured from external suppliers they are assembled into the systems at Stevenage and then system tested at various sites across Europe. This is all prior to the support provided for the launch campaign at launch sites across the globe and then the subsequence onstation or inflight operations. The Principle Propulsion Design Engineer will be required to Perform the role of Propulsion Architect in the generation of system concepts. Tasks include component selection, system analyses and the generation of the associated documents for proposals, and design reviews. Perform analyses and build theoretical models relating to gaseous and liquid pressure drop theory for pipes, components and orifices, as well as thermodynamic behaviour of fluids. It will be necessary to utilise existing EADS Astrium code or to create purpose built models and analyses using commercial software. Work with 3D CATIA engineers in order to generate mechanical layouts, as well as detail design and manufacturing data. Present the propulsion system design to customers with the use of presentations and formal design review packs and meetings.

Report: Evidence backs greater role for environmental 'precautionary principle'

2013-01-23 11:42:00| Climate Ark Climate Change & Global Warming Newsfeed

BusinessGreen: Policymakers and businesses have been urged to take a more cautious approach to the development and deployment of new technologies, following the publication today of a major new report arguing that early warnings from scientists about the environmental impacts of new technologies are often entirely justified. The 750-page study from the European Environment Agency (EEA) provides an update to the Late Lessons report of 2001, which explored how new technologies were later found to have harmful...
