Electricity as a modern convenience!



The Home Electrical was the name of this film by GE Co.
It promotes all the modern conveniences that were new at that time, which could be useful in the home. I noticed that some of those appliances could be a safety hazard waiting to happen. I looked at the gears by the washing machine and thought of how careful mother would have to be if children were nearby, while she was washing the clothes. The electric cup used for warm shaving lotion could fall in the sink if full of water with the cord plugged in and cause a shock. The electric cigar lighters would not be a safe thing to leave in a house with children, in case they wanted to stick their finger in it. Those were just a few of my thoughts when I watched this film. I wonder if anyone else may have noticed anything.
We are lucky that today the standards of safety have changed when it concerns electrical appliances. It was such a fad at that time people probably never gave it a thought.

This movie was taken from the open source files under CC license and public domain.
I gather it may have been made around 1915 or so.

Popular Alternative Electricity Sources

The need for alternative electricity sources is more important now than ever before, and the pressure is on each and every human being to do whatever it takes to conserve the precious natural resources of the Earth. There are a number of alternative electricity sources that can be used including wind power, solar energy, geothermal energy, bio fuel, and many others.

Wind Power

Perhaps one of the more popular alternative electricity sources is one which is created through wind power which essentially involves harnessing the energy of the wind through various methods in order to convert it into a valid source of electricity which can be used to power homes, businesses, and anything else that uses electricity. The wind turbine is a popular mechanism that is being used for the purpose of generating electricity from wind energy.

Solar Energy

Another very popular means for generating an alternative electricity source is through the use of the energy created by the sun. Solar panels are created to catch the light that is projected from the sun and convert that energy into electricity which is safe for household and business use.

Geothermal Energy

Geothermal energy is energy that is pulled from within the earth, particularly the various interior levels of the earth where thermal energy is present. The energy within the earth has been there since the earth was created.

Bio Fuel

Bio fuel is fuel that is made not from common sources such as coal or other materials, but instead is made from different types of plant materials. There are a number of different plant materials that can be used including wood, wheat, corn, and many others. Bio fuel can be used to power energy generators and other various equipment that is used to create electricity.

With so many different alternative electricity sources available, one would think that the need for using more common sources such as coal, nuclear power, and natural gas could be greatly reduced. There are a number of energy creating solutions such as wind turbines and solar panels that are being used more and more, but unfortunately the process of converting completely to alternative electricity sources is a slow one.

As time goes by, the need for alternative electricity sources grows more and more pressing due to gas shortages and wasteful natural resource consumption. Will we eventually resort to only using one of these renewable energy sources, or many of them? Only time will tell. Whether or not we as a population are able to switch completely to one of the many renewable energy sources mentioned above will depend on a number of factors such as technological development and cost efficiency.

Home Lighting Design Tips

Home lighting design tips are important for homeowners who are not very aware of the best systems and trends. Home lighting isn't as straightforward as it might seem, because different areas inside the home have drastically different needs. The living room is completely different from the kitchen and the dining room needs lighting that is unrelated to the bedroom. It is therefore important to know which kinds of lighting are suited for which areas in the home.

By using the right elements, you can get a greatly aesthetic home that looks and feels just right. In addition, lighting greatly improves the value of a home, both for the homeowner and the resale value, so it is a wise investment for both the short and long term.

The living room is one of the most important rooms from a visitors' point of view, so you want the lighting to be just right. The best kind of lighting for the living room involves complete lighting of the area. There can also be task lighting to highlight some important elements in the living room, like medals, certificates, antiques, etc. Living room lighting should also preferably be flexible to accommodate different needs and times of the day. For this, having central lighting is not good enough; you should preferably have some recessed lights in the corner as well to complete the lighting needs.

The bedroom should really have the perfect lighting for you so that it can be changed from a bright lively room to a cozy romantic one within no time. Thus there should be minimal ambient light and on top of that, you should have elements that allow you to focus light as and when you need. The ambient light needs to be soft and romantic. Usually, a central bright light is used for general work inside the bedroom and side lights for reading. However, it is best to have dimmers so you can adjust according to your mood. Soft lights are also essential to ensure a good night's sleep.

The kitchen needs to be brightly lit, as you need adequate light to carry out cooking. Lighting is important in a kitchen to avoid any accidents as well, so they are needed from a safety point of view as well. There are areas in the kitchen that need more focused lighting, like a stove or a platform for chopping and slicing activities.

A bathroom also needs the right kind of lighting to give a good and relaxing experience. Areas like the shower and sink need additional lighting apart from ambient background light. Most lights inside the bathroom should be about relaxing and thus soft instead of harsh and bright. LED's work especially well for the bathroom.

Garden lighting is another important aspect that is often neglected by homeowners. You should have adequate lights in your garden to make it look aesthetic and beautiful. It is important to have dim and minimal lighting only, since you are only interested in highlighting specific plants and other garden elements. Step lighting into the garden is becoming fashionable and you can consider this for your garden too.

Potato could provide electricity to millions


More than 1.6 billion people in the world have little or no access to electricity and most have no way of accessing modern electrical technology, such as like electric lighting, mobile phones or televisions.

But scientists at an Israeli university say they have made a remarkable discovery in relation to the potato which may bring electricity to millions of the world's poor.

Wind Electricity - A Complement to Solar Power System

Wind electricity has made huge gains in the last couple of years, and today it remains one of the most cost-effective of all the renewable energy technologies. It is an excellent complement to the solar power system. In some parts of the world, when sun is not shining, the wind usually blows. Wind power is useful in the winter weather to capture both the strong and gentle mountain winds during the times of slightest sunlight and it simply fills in the gaps left by solar power. Why wind electricity? Wind energy is abundant and limitless. It is present in the four hemisphere on Earth. According to Home Power Magazine, wind electricity is created through rotating blades convert the wind kinetic energy into rotational momentum in a shaft. The rotating shaft turns an alternator, which makes electricity. This electricity is transmitted through wiring down the tower to its end use.

What are the benefits of using the wind electricity? Wind electricity helps us fighting climate change. We know already what happen to the world today. There is a sudden shift of changes in the weather. By using wind electricity, it avoids people using harmful pollutants that cause climate change. It does not produce ill effects in the environment. It reduces carbon monoxide and sulfur dioxide emissions. Second, wind electricity is cheaper. Wind energy does not deplete natural resources. Wind is renewed every day as the earth heats and cools. It is more efficient compared to the conventional electricity using fossilized fuels. Engineers have design wind turbines that produced more electricity making it the cheapest form of renewable energy.

Third, according to study, wind electricity is gaining popularity because it is known for its cleanliness and it is known for its industrial safety. No accidents happen for people working in the wind industry. No one have ever been killed by a wind turbine. Fourth, conventional electricity requires hectares of lands to acquire the fuel such as mining, making pipelines, and building gigantic power plants just to generate electricity. But wind power uses only less land and turbines make up less space than the average power station. Windmills only have to occupy a few square meters for its base; this allows the land around the turbine to be used for many purposes, for example for farming.

The downside for the wind electricity is the noise pollution of the turbines. According to people who lives near the wind farm expresses that commercial wind turbines is compared to a noisy engine. Protests and petitions usually brazen out any proposed wind farm development. People feel the countryside should be left in untouched for everyone to enjoy its beauty.
