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 …

Solar inverters improve the profitability of photovoltaic power plants

The Siemens Industry Automation Division is further expanding its product portfolio in the power plants segment by introducing the central inverters Sinvert PVS600, PVS1200, PVS1800 and PVS2400.
These four new models cover the 600 to 2400 kilowatt (kW) output range and enable operators of photovoltaic (PV) power plants to tune their inverters precisely to the capacity of the modules employed in the plant. In this way, the yield and efficiency of the entire PV plant can be optimized.
The planning process is supported by Sinvert Select, the cost-free Siemens software application, which is capable of calculating suitable combinations of inverters and PV modules. Sinvert PVS inverters have a peak efficiency of well over 98 per cent, making …

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 …

Solar panel installation

Solar panel installation:
In today’s world of advanced technology, we need to understand the source of energy from the sun and learn how to use that energy most efficiently. Did you know that you can lower your monthly utility electricity bills by reducing the amount of regular electricity that you use at home? By installing a solar power kit at home you will be reducing the amount of fossil fuels that are being used which in turn helps to protect the environment.
If you want to convert your home to solar power, there are a few things to consider. The amount of energy do you use in your home? What types of appliances would you need to …

What are the advantages of biomass electricity?

Today we live in the world which is rapidly changing and moving fast. The speed at which we are affecting our ozone layer is very fast, as we can imagine how the weather conditions use to be 20 years back and now how the weather is changing. The glaciers are also melting at a fast rate and this is now creating many problems for the people. We must act fast and switch to environmental friendly products. Environmental friendly products do not harm the ozone layer and this is one of the main advantages of biomass energy. Biomass energy is the best alternative source for producing electricity, fuels and other in other form of industries.
Biomass is …
