Direct Conversion of Solar Energy into Fuel

john April 1, 2011 5 Comments
The concept of transforming solar energy directly into fuel is not easy. The method was tried out by researchers for the past decade and many prototypes were developed. But all the past attempts had some basic problems like life span, cost and efficiency and even the combination of all three. Some ideas remained intact as the materials required to conduct the experiment was very costly and were also not abundant. As the basic idea was to commercialize it, there...

Metal Oxide Varistor (MOV)

john March 24, 2011 9 Comments
Metal Oxide Varistor (MOV) Basics of Varistor A varistor/voltage dependent resistor (VDR) is a component which has a voltage – current characteristics that is very much similar to that of a diode. This component is used to protect electrical devices from high transient voltages. They are planted in the devices in such a manner that it will short itself when a high current is produced due to the high voltage. Thus the current dependent components in the device will...
