What are the emerging trends in engineering?
Some of the emerging trends in engineering include nanotechnology and hybrid transportation. There is a push to make cars more fuel efficient and environment friendly by developing cars that use bio-fuels, electricity and solar.
What other energy sources could replace the use of petroleum?
There aren't many energy sources that can replace petroleum. Petroleum - gasoline and natural gas - is both energy-rich _and_ easily portable; very few energy sources meet both criteria. In most applications, you would need to combine two or more power sources to replace the petroleum. Electrical: In order to be portable, you'll need to store the electricity. Batteries are heavy and not particularly efficient. Charging the battery can take considerable time, and the batteries themselves can undergo a finite number of recharge cycles before they need to be replaced, and batteries can be expensive. The electric energy used to recharge the battery has to come from someplace, and that's generally a power plant that uses hydroelectric, nuclear, coal, oil, or natural gas. Wind: Wind power isn't constant, and varies too much over the course of a day. We can't use wind power for vehicles, although sailing ships using solely wind power crossed the oceans for hundreds of years. Nuclear: Nuclear power plants are massive. They're "portable" in ships, but not in land vehicles. Nuclear powered ships can sail for a couple of years before needing to be refuelled. Hydroelectric; Hydro-electric power is generated by using running water to spin turbines to generate electricity. At its simplest, this can be something as simple as a water wheel, but to generate substantial amounts of energy, we'll need a large volume of water falling quite a distance. That means a high dam, with lots of water behind it. That's not at all portable, of course, but it's generally pretty reliable and constant. The flooded valley behind the dam can have its own costs; however, the water storage, flood control and recreational resource aspects make hydroelectric dams an attractive option. Solar: Solar power works as long as the Sun is shining. You'll need batteries (see above) for night time or periods of bad weather. Alcohol-based fuels; We can convert plant matter into alcohol and use the alcohol as our portable fuel. However, alcohol contains less energy (fewer BTUs per gallon) than gasoline, and the plant materials aren't easily fermented to produce alcohol. In current alcohol production, it takes gasoline and natural gas to make the alcohol, so we often get less energy from the alcohol than we spent in fossil fuels to make it. Also, current alcohol production is almost totally dependent on corn, so we're using food to create fuel. The price of corn has recently risen high enough that some people are struggling to afford the food that we're turning into alcohol. And if we devote acreage to grow some other plant, we're decreasing the amount of edible crops we can grow. It's sometimes an uncomfortable tradeoff.
How do you find voltage rating of zener diode?
It should be marked, either on the diode or on the box it came in. If you can't find the mark, then you have to measure it yourself. Take the zener diode, a battery or DC power supply, and a resistor. Wire them all in series, with the NEG (cathode) end of the diode closer to the POSitive side of the battery or power supply. Connect your voltmeter across the diode, and slowlyincrease the power supply output voltage while watching the meter. You'll see the voltage across the diode increase slowly, tracking the power supply, until you reach the Zener voltage. At that point, the voltage across the diode won't increase any more; it'll just stay there at its 'reverse breakdown' voltage, which is the Zener voltage. (If the voltage across the diode goes to around a volt and won't go any higher, the polarity is wrong. Reverse either the diode or else the power supply.) You probably want a wild guess at what the value of the resistor should be. That's difficult to specify if I don't know the power rating of the Zener diode you're testing. I'm going to make the following suggestion completely in the blind: Select the resistor to limit the series current to 30 mA even if you have to crank the power supply up to 50 volts. R = 50/.03 = 1.5 to 2 K-ohms, rated for a couple of watts.

The electricity energy that is transferred in a TV comes from a power stationwhere is the energy transferred from to make the electricity in the power station?
Depends on what kind of power station it is, can bea nuclear power plant, a coal-burning power plant, a wind turbine, or a hydroelectric power station.
What is coal sed for?
Coal is used for burning to make heat. At home in a fire, at a power station to generate electricity.
Do geothermal power stations make pollution?
No. Construction equipment used to build the station will burn fossil fuels and produce some pollution. When the station is complete it will produce pollution free electricity. The station will require some electric power from the grid to operate, and some of that electricity may be produced by coal powered plants which do produce pollution, but the geothermal power station will not produce pollution.
What are the Inputs of a power station?
Inputs of a power station is the air inside it produced. :) But seriously: The input to a power station is the source of energy use to make electricity. This can be water, oil, gas, coal, nuclear. In less conventional terms, wind turbines and tidal schemes are 'power stations'.
