What is the establishment cost for a coal burning factory?
I need this for a science assignment. Holy crap do I hate science.
So yeah, what is the establishment cost to set up a coal burning factory? (Where the coal is transferred into energy)
admin answers:
The current establishment cost of a coal fired power station is about $2000 per kilowatt of power produced. Over a 50 year life; this is quite low compared with establishment costs for wind and solar power generation, and a lot (hundreds) of wind generators are needed to produce the same power output of a large coal powered generator. This is why it is proving difficult to replace coal for large scale power generation.

Year 12 Physics – How do generators and transformers work?
I have a basic idea but am having a little trouble understanding it completely – so i can answer abstract questions in texts… and the textbook is just confusing.
Anyone want to explain a little?
admin answers:
A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled electrical conductors. A changing current in the first circuit (the primary) creates a changing magnetic field; in turn, this magnetic field induces a changing voltage in the second circuit (the secondary). By adding a load to the secondary circuit, one can make current flow in the transformer, thus transferring energy from one circuit to the other.
The voltage in the secondary circuit is in general different from the voltage in the primary circuit.
In electricity generation, an electrical generator is a device that converts mechanical energy to electrical energy, generally using electromagnetic induction. The reverse conversion of electrical energy into mechanical energy is done by a motor, and motors and generators have many similarities. The source of mechanical energy may be a reciprocating or turbine steam engine, water falling through a turbine or waterwheel, an internal combustion engine, a wind turbine, a hand crank, the sun or solar energy, compressed air or any other source of mechanical energy.
