POLLUTION

POLLUTION:
We are all aware o the word pollution ,but don’t understand it.
So, let me please try to understand all of the readers through blog channel.
Lets start with the types of pollutions in the world,
1.water pollution.
2.land pollution
3.air pollution
4.Noise pollution
Lets explain:
1 .Water pollution:
When the water is get mixed with unclean mattles, human and animal wastes ,poisoned wastes of factories,it becomes a polluted water.
When human and animals discharge their wastes on the land, it gets mixed in the rivers due to rain and also absorb in the land and pollute the underground storage of water.and when we drink this water a lot of diseases attack upon us.So for avoiding ,we have to relocate these wastes to safe places so that it cant mixed with water.
2. Land Pollution:
The main reson of land pollution is human and animal wastes, if we cant take these wastes to safe places ,we cant get rid of land pollution.
3. Air pollution:
Air pollution is most dangerous type.
It causes due to discharge smokes of vans ,motor cycles, buses etc. these smokes are mixed with air and make it polluted.
And when we inhale oxygen lead particales of smoke are also inhaled and cause very serious problem like cancer,inhale problem,etc.
So,we have to take urgent steps to minimize it as abandon the use of vehicles which are very old and discharge a lot of smokes.
4. Noise Pollution:
In overcrowded areas, we face noise pollution due to vehicles noise,unnecessary pressure horns,loud music etc.
SO, we all also take steps to overcome it because it causes tensed environment and causes serious mentle problems.From: Engineer Waqas

electricity production

dear,
The big problem in the pakistan now a days is electricity crises,
almost all industries are closed due to this reason,and also a lot of people have no job,the situation is growing more and more dangerous.
So,its my humble request to all managment officers and scientists to locate other electricity generation mathods to overcome the shotfall of 3 to 4 thousand MW energy.
Our beautiful Pakistan has a lot of energy sources,like wind power,solar pannels,hydel power,nuclear energy,coal energy,and much more.
So i again request the higher authorities to utilize these sources as soon as possible.So that dangerous situations can be controlled.

solar technique

when the light photons strike the solar cells,they emit the dc current from the cell,and we get dc power from the solar pannel,
then after this,,we invert the power into ac by inverters and utilize it.
