Scientists examine energy trends of communications equipment

Increasingly important problem for networks examined at Frontiers in Optics Meeting
A team of scientists at Alcatel-Lucent Bell Labs have examined the energy consumption trends of communications equipment in use today and determined that gains in energy efficiency are not keeping pace with traffic growth. One consequence is that energy is going to become an increasingly important problem for communication networks.
In one unabated, business-as-usual scenario, the scientists estimate that power consumed per user could increase by seven-fold over the next 10 years. Based on these findings, Bell Labs has developed several technology evolution scenarios for the coming decade, which they will present at Frontiers in Optics (FiO) 2010/Laser Science XXVI — the 94th annual meeting of …

PolyU researchers make innovative use of solar energy

Working in collaboration with industry partners, researchers of The Hong Kong Polytechnic University (PolyU) have successfully developed a Solar-powered Air-conditioning System for vehicles and completed a series of testing on the road.
The innovative system is developed by Professor Eric Cheng of PolyU’s Department of Electrical Engineering together with Green Power Industrial Ltd.
With the support of Swire Coca-Cola Hong Kong, the system has been installed on the top of a truck for carrying beverages and proved to work on the road.
PolyU President Professor Timothy W. Tong hailed this innovation as a practical solution to providing green energy for the much-needed air-conditioning system for professional drivers in Hong Kong. He also expressed gratitude to the support of …

Charging for plastic bags cut bag consumption by half in China

Research from the University of Gothenburg (Sweden) shows that people in China – the number one consumers of plastic bags in the world – reduced their consumption of plastic bags by half when stores were forced to charge consumers for the bags.
Use of plastic bags is a growing global environmental problem. As a result, the bags are becoming subject to various regulations in an increasing number of countries, with mixed results. An environmental-economic evaluation of the Chinese ordinance against free plastic bags from June 2008 shows that people in China – the number one consumers of plastic bags in the world – reduced their consumption of plastic bags by half when stores were forced to …

Wayward Winds – Predicting The Output Of Wind Parks

For the first time, scientists are comparing methods for predicting the power output of wind parks in Austria.
The project, supported by the Austrian Science Fund FWF, thus creates a basis for optimised forecasts of wind park outputs – forecasts that can be used to make better decisions about which measures to take to ensure the need for power is met.
The project focuses on forecasts for periods from six hours up to ten days. In addition to reliability, the temporal and spatial resolution of the different methods is analysed. The scientists also evaluate to what extent these methods are able to calculate the probability that these forecasts come true.
Natural energy sources are fickle. It is a …

Call to Heal the World’s Coral Reefs

There is still time to save the world’s ailing coral reefs, if prompt and decisive action can be taken to improve their overall health, leading marine researchers say.
Writing in the journal Trends in Ecology and Evolution, eminent marine scientists from Australia and the USA have called for an international effort to improve the resilience of coral reefs, so they can withstand the impacts of climate change and other human activities.
“The world’s coral reefs are important economic, social and environmental assets, and they are in deep trouble. How much trouble, and why, are critical research questions that have obvious implications for formulating policy and improving the governance and management of these tropical maritime resources,” explains Jeremy …
