Harnessing Nuclear Power with Fission or Fusion Processes?

Posted in Energy-Efficiency on November 7th, 2011 by Jim – Comments Off

Let me just start this article with the fact that nuclear fusion is highly experimental, and even if the research has come a long way, we are still several decades away from using this energy source commercially. However, nuclear fusion has several major advantages over convectional energy sources today, and even though the principles behind are somewhat similar to nuclear fission, the potential is on another level.

What is Nuclear Power?

Nuclear power is the source of energy that fuel most of the processes in the Universe, responsible for the creation and destruction of starts, as well as the being the life force behind them. It is the solely most potent form of energy we have so far discovered and scientist have been working the last 70 years on how to tame and harness these processes for generating useful energy.

They have come a long way. It did not take many years after the nuclear bombing of Hiroshima and Nagasaki, before nuclear fission reactors started popping up around the globe.

Nuclear Fusion

Nuclear fusion is the name of the process where two lighter atoms merge into one (the opposite of nuclear fission), and in the process has net loss of mass. This mass is converted into massive amounts of energy through Einstein’s formula E = mc^2, where the constant c is the speed of light. There are several large obstacles when it comes to harness nuclear fusion, one of them being finding the right material to sustain the amount of heat that is required to actually make these atoms merge together.

Abundant Fuel

Nuclear fusion can use (unlike nuclear fission that requires uranium or similar heavy atoms) seawater as fuel. That is we extract the deuterium hydrogen isotopes out of seawater. It has been estimated that about 1 liter of seawater is equivalent to 100 liters of petrol.

Relatively Low Radioactivity

The other major advantage of nuclear fusion is the fact that the radioactivity (both in half-life and strength) of the byproducts of nuclear fusion are much milder than that of nuclear fission.

Fusion is The Future

If we one day are able to harness the awesome power of nuclear fusion (the same source that fuel’s and keeps the sun alive and burning), then we have reached a major milestone in human history. This is the day our energy system is transformed, our dependency for non-renewable and polluting energy sources is lost, and we are closer to a completely green and clean future.

Eco Friendly Homes: How to Install A Solar Panel

Posted in Energy-Efficiency on August 4th, 2010 by Jim – Comments Off

Installing a solar panel in your home is a great way to utilize renewable energies and to make a more eco friendly home. Solar panels produce power by using the photovoltaic rays of the sun and converting them into energy.

One of the best reasons to install this device in your home is the investment. This investment has a low ROI but is safe for the long term. You also see some immediate benefits when you install a solar panel. Your energy bill is lowered or even completely eliminated and you can even sell off the extra energy your produce straight back to the energy companies. Another benefit is that you can sell your clean energy credits to other companies.

Investing into solar panels can be a costly endeavor yet there are always ways to offset the initial costs of your investment. One of the best ways to do this is to actually build your own solar panels using recycled solar cells or build your own kits.

When looking for new and complete solar panel kits there is a wide variety of high quality manufacturers to choose from. Some of these include Mitsubishi and Evergreen. There are also many lists around the internet which list the prices of solar panels in comparison to there kilowatts of energy produced.

One important thing to note is that you should be cautious of purchasing any solar panels from China. Solar panels produced in this county flag quality concerns and it might be hard to get any type of service provided or to use any type of warranty provided.

Now we will talk about installing your solar panel on your home. There are other types of solar panels which can be used for other situations such as for a motor home or for a boat but we will only be talking about using these for your house.

When you are deciding on where to install your solar panel there are some things that you must consider. First on the list is what type of area you are going to install it onto. There are three major places you can place your panel; on your roof, on the roof of another structure and as its own standalone structure.

Then you must find the area of your property which gets the most sun exposure during the ENTIRE year. Remember that the sun moves depending on the season. Also make sure that your panel will not have any shade cast onto it by obstructions such as trees. The more sun that your panel gets during the year the more energy it will produce for your home.

The last step in preparing to install your solar panel is choosing a solar panel mount. These mounts each serve a specific purpose. The three main varieties are pole mounts, flush mounts and roof-ground mounts. There many many articles around the web where you can find more information on these types of mounts and which one is best for your specific purpose. Once you decide on a mount you can then install your solar panel and the method of installation is determined on your specific mount.

Draught Excluders And Why Insulating Saves Money and Energy

Posted in Energy-Efficiency on May 29th, 2010 by Jim – Comments Off

Insulating your home can save energy and  it can also save significant amounts of money. Poor insulation can mean severe losses of energy and this will show on your electricity bill in higher charges, as your radiators work overtime. Insulations are the easiest way to save on electricity bills and insulation also has a positive environmental impact.

Older buildings are usually in a need of insulations more than modern buildings. New apartments often have double glazing, an excellent way to prevent draughts. A lot of heat can be lost through windows, and double-glazed windows are one of the cheap ways to insulate any house.  If you want to start insulating your home, begin with the windows. If your home has an attic, this can be insulated to prevent warmth from escaping. Fiberglass or cellulose are some of the commonly used materials for attics. For houses that have basements, it is important to insulate the to keep away cold basement air or moisture that can creep in through the floorboards.

You can seal some parts of the house yourself, but in most cases it is a good idea to get a professional in to check what type of insulation is needed and how much you need to insulate. This will determine the cost of the project. You should then get a quote, or possibly several quotes from different companies, and discuss your options for the materials to be used. Insulation is a way to keep the house warm and cozy even during colder seasons, but it can also add value to your house. More and more house buyers place a lot of importance on energy saving features when looking for a new home, and if you ever decide to sell the house, insulating is one of the best investments you can make.

Simple ways that you can improve the the energy efficiency of your home is to fit draught exlcuders to the base of your doors and buy a letter box draught exluder. The benfits of draught excluders are discussed futher at myhomedepo.com.

Installing Solar Panels at Home

Posted in Energy-Efficiency on April 14th, 2010 by Jim – Comments Off

The whole Earth depends on the sun’s energy. Trees do not grow without it and people will not be able to eat without the sun because crops will not grow and it would be impossible to raise livestock. But even with this information only a small percentage of the sun’s energy is used in homes and in our transportation systems. The good news is solar energy has been used by industrial companies for years now especially those operating in remote areas.

Installing sun-powered panels in your home is one great way to save on your energy bill and do your part in helping the environment at the same time. Make your home into a solar home and gain more energy than your house will ever need. The energy you can get from the sun can vary. If you live in a sunny place, you are likely to get a greater amount of energy compared to colder places. This type of energy is dependent on the weather so getting enough energy during those long, winter months can be a bit difficult.

Installing these panels is one good way to have a “green” house but getting solar panels can be a bit expensive because the competition is minimal and government regulations do not allow homeowners to install their own solar panels.  This is one of the major problems in the US today that is why not many people can have access to a solar home. In Europe this is not the case; many modern homes now have solar panels and no longer use up much electricity to maintain the heating system.

Apart from installing solar panels at home, you also need to make sure that you doors, windows and even your wall panels are energy efficient and do not have leaks. Preventing air coming from your cooling or heating system to leak to the outside is a good start for those who want to save on their energy bill. Before installing panels you may need to install insulation to parts of your home.

Adding Attic Insulation To Save Energy And Money

Posted in Energy-Efficiency on April 9th, 2010 by Jim – Comments Off

If you live in the midwestern or eastern parts of the United States, you’ve just come through an incredibly tough winter.  Snow, ice, and most of all bitter cold winter enveloped your home for at least 5 months.  If you are like me, you probably had to visit your attic space at least once this winter because you use it for extra storage space in your home.  I remember particularly this winter how I got a cold blast of air in my face as I pulled the loft ladder down and poked my head into my attic.  It was time to consider adding more insulation to my attic for sure.  Many of us who own homes already are aware that attics can leak energy quite easily.  This means that as more heat goes out, more money is going out also.  In the winter…heat equals money!  Adding blown or rolled attic insulation is a great way to stem the leakage, preserve your home’s warmth and save money all at the same time.

Knowing the details of how to insulate your attic is important for  homeowners.  For those of us who are used to living in these harsh cold climates, doing your own insulating saves heat in in the winter, and eliminates air drafts, especially those that blow through joints, cracks, outlets, and door jambs.  In more moderate climates, believe it or not, the insulation actually helps keep the warm air outside the home, and keeps the air conditioning focused on cooling the living space of your home. Fortunately either climate is right for the type of insulation we are discussing.

Generally speaking, there are two types of insulaton that can be used in attics: rolled batting and loose-fill insulation. A third type of insulation is spray foam insulation and it is very good in sealing cracks and joints that traditional fiberglass or cellulose insulation can’t get to.  Though installation costs can differ, loose-filled insulation is usually cheaper to install, and if done correctly will provide better insulation for the home.  There are 3 types of  this type of attic insulation:rock wool, cellulose, and fiberglass.  Each type has advantages and disasadvantages but the net result is that basically they all provide similar insulating ability. The difference is in actually how easy or difficult it is to do it yourself.

Most home improvement retailers in your area will have knowledgeable sales people who can assist you in picking out the right types and amounts of attic insulation that you will need for your home.  Also, there are specialty online websites that give many consumer details on the best choices to save energy and money.
