Natural Gas vs Coal

Natural Gas vs Coal: Undoubtedly, high efficiency natural gas-fired power stations can produce up to 70% lower greenhouse gas emissions than existing brown coal-fired generators, and less than half the greenhouse gas emissions of the latest technology black coal-fired power stations. Notice the distinction between black and brown coal, however,...

Geothermal Energy & Plants

Introduction Deep inside the Earth lies the top layer of the mantle consisting of hot liquid rock called magma. Underground, water can be heated up to boiling temperatures and turn into steam through the heat emitted by these rocks. Harnessing the thermal energy fomr hot water and steam, we can...

The Savonius Wind Turbine

These plans are for the construction of vertical axis wind turbine, modelled after a design by the Finnish engineer S.J. Savonius in 1922. His idea was to mount two halfcylinders on a vertical shaft. It was simple to build, and could accept wind from any direction. However, it was somewhat...

Fuseboxes

Definition of a Fuse Box A fuse is a safety device to prevent excess current flowing in an electric circuit. It consists of a thin metal wire of low resistance and low melting point. When an electrical appliance or some other piece of electrical equipment becomes faulty, therefore allowing an...

Conductors and Conductivity

There are many materials that allow charges to move easily. They are called conductors. Conductors have the quality of conductivity. I guess that’s not a lot of help for you. The reality is that you just need to understand the difference between those two words. The conductor is the object that...
