Electricity: Useful Or Harmful?

Friday, April 22nd, 2011

The uses of electricity in the house cannot be downplayed. We use electricity daily, and life without it will be unimaginable.

Nevertheless, electricity could likewise be hazardous. Now and then, news of electricity-caused accidents come up leading to fires, electric shock, or fatality. In the house, a seemingly innocent wire can be deadly should it is actually electrically connected, the risk being increased due to the invisible nature of electricity.

So as thus to avoid accidents because of electricity from happening in your home, it is imperative that people at home, particularly the kids, know and appreciate the dangers of electricity.

Primarily, indicate identified electric dangers with proper sign for safety for everyone to avoid.

See to it that the power source is protected with fuses of the appropriate capacity to guarantee that circuit switching off would automatically occur if there be a short circuit.

Moreover, have their locations be readily known, probably with the aid of safety signages, and have these switches be familiarized and easily reached by adults to immediately switch them off manually in case of emergency.

Provide a ground fault circuit interrupter (GFCI), especially at the bathroom and the kitchen, to immediately break off the power source in case of ground fault. Water is a good conductor of electricity; therefore, the possibility of these faults to occur here. Also, keep from using electric appliances when wet or standing on a wet floor.

GFCI could accurately detect this type of fault and interrupts the circuit quicker than the circuit breaker can, thus probably saving you from injury or death within the little time difference.

Supply electric outlets with safety cover and teach children never to insert their fingers or things into them to prevent electric shock. Supplement this with placement of custom safety signs and symbols for emphasis.

Circuit overloading and loose connections are fire hazards. It is simple to eliminate these dangers by avoiding overloading of outlets or circuits. Allocate load reasonably and, if possible, learn the load capability of a connection and the load of gadgets that you use. Regularly check splices for loose connection as might be shown by carbon or sparking.

To derive the benefits of electricity to the fullest while having peace and security from its risks is our final goal. There are a lot of safety instructions and guides obtainable, and knowing, understanding, and heeding them would guarantee achievement of this target.

Solar Panels For Generating Cheap Electricity

Tuesday, April 19th, 2011

Are you interested in having home solar panels? Do you know you can actually generate electricity and heat water while saving money? Solar power is friendly to the environment as it does not release pollutants and by-products. For $1500 to $2000, you can generate 1 kW for your house! This is far cheaper than purchasing solar panels pre-made or hiring a solar energy construction company.

Why spend $20,000 for assembly and installation, when you can build a home solar panel by yourself? Don’t worry if you are a novice in electrical engineering, because there are many affordable books and guides for DIY solar panels. Just check if the providers of the guides are reliable and licensed. Amazingly, the materials and tools are not expensive, and you can buy them from your favorite hardware shop.

The most important consideration, perhaps, is the energy requirement of your house. Download a chart or use free online calculators to find out your energy requirement. This depends on the types and number of home appliances. The number of required panels depends on the result of these calculators.

You don’t have to remove your previous wirings from the grid electricity. Your solar panels and grid line can be connected to a switchboard or console. This component will manage the flow of electricity to power your house. If you build a DIY solar panel, you will not utilize grid power. If you generate surplus electricity, your grid provider will even pay you.

Do you wish to save more money? You can build a home solar panel or collector for water heating. The “batch collector” is the easiest type to prepare. Generally, it is an insulated box that contains the metal water tank. All sides of the box must be light proof and insulated except for one. This exposed side is also called the glass side. You can make a glass side by using double or triple glazed glass. Glazing will improve heat absorption and retention. As for the light proof sides, you can use multiple layers or combinations of wood, Styrofoam and plastic. You can also use concrete.

If you plan to build a DIY solar panel either for powering or heating, positioning is very important. Observe which part of your house receives the longest hours of sunlight. Take into account the shadows cast at different times of the day. As for the batch collector for water heating, elevation is also essential. This will make it a passive pump that does not need extra motors for water pressure.

Nuclear Power Plants: Are They Safe?

Friday, March 25th, 2011

The bombing of Hiroshima and Nagasaki near the end of the Second World War, which brought about numerous deaths and untold destruction, was a manifestation of  the destructive power of the atom, which instills fear to all the people then and now.

The same energy nevertheless has been established to have better utilization in other applications, more practically in the production of electric power. Nevertheless, the events quoted earlier have made people to still be fearful with the construction of nuclear power plants to generate electric power. A lot people inadvertently tremble when confronted with various danger safety signs and symbols at nuclear power facilities.

Incidentally, assessing more than 40 years of existence of commercial nuclear power plants, no major accidents however occurred that justified the horrible images of the result of a nuclear-plant meltdown, except for those of the Three-Mile Island accident in the U.S. and the Chernobyl accident (in the old USSR bloc). The former exacted no loss of lives or personal harm nor damage to the environment. The latter claimed over 30 lives and caused environmental destruction. In truth the Three-Mile Island accident proved how safe implementations of nuclear power plants then, which are continually being improved, even though the same cannot be supposed of the once tightlipped Soviet Union.

The use of oil fuels and coals is known to have produced big destruction to the environment and instrumental in global warming. On the contrary, nuclear power plants had effectively no greenhouse-gas emission.

The common power plants have directly or indirectly cost more lives than the operation of the nuclear power plants in their near 40 years of existence. As an illustration, many coal-mine workers are killed in mining of coals to power conventional coal power plants.

State rules together with those of the International Atomic Energy Agency implement very exhaustive measures for nuclear power-plant establishments and operations. Spread of damage in case of breakdown is guaranteed with a minimum of up to three levels. Protection is similarly completely assured even in cases of human error or series of human faults. These protections are notwithstanding the regular putting up of basic notice signs and danger warning signs to motivate nuclear operators always on alert.

Nuclear power plants are assuredly very safe compared with traditional power plants. The dangers are really overstated, with the possibility of design mistakes virtually being zero. Hence, nuclear power plants are almost risk-free with respect to its operation and are certainly environment-friendly producers of electrical power. The only danger is human terrorism, unhappily a fact that is underlying not only in nuclear power plants but also in virtually all situations in regular lives. However, safeguards against these are also strictly installed in nuclear power plants.
