|Power from the Sahara|
The European Union is proposing an ambitious venture to install solar panels in the arid stretches of the Sahara, the world's largest desert.
These solar panels will be of the concentrated solar thermal type. consisting of a parabolic mirror which will focus the light and heat to a central tower. An engine in the tower( Stirling engine) will convert the heat to mechanical energy which will power a generator. This method is superior to the photovoltaic type of solar power generation in that it enables the heat energy to be stored and enables power generation during night time as well using the accumulated heat....Read More
|Photo-Voltaic Cells - An Overview||New DSO1000A series Oscilloscope from Agilent|
|Photo-Voltaic energy is an ideal choice of power for locations which are far from the electric grid.
In many countries, it is not feasible to lay power lines to certain far-flung
|Agilent Technologies have launched their new DSO1000A series of oscilloscope. Weighing within 3 kgs, the unit comes with a 2 or 3 channel facility.|
The instrument has a bandwidth between 60 MHz to 200 MHz. It has a sampling rate of 2 GSa/s. It has a "True Zoom" mode that enables the user to zoom into a particular part of the waveform and display the entire waveform at the same time.The device can display about 21 measurements simultaneously....Read More
