Home Solar Power
The Radiant Energy emitted by the Sun is the greatest source of energy that the earth has. The only problem has been our inability to harness this energy since it is not a concentrated source of energy. But since the earth is constantly being engulfed in it, man has attempted to tap into this source of essentially free energy. With the development of Solar Cell Technology, and the evolution of Solar Cell Technology that has occurred over the last 30 or so years homeowners can now tap into this vast energy resource saving themselves money while reducing their Carbon Footprint.
Photovoltaic Technology
The creation of the Solar Cell made it possible for us to tap into the enormous amounts of solar energy that the Sun emits to produce electricity. Initially Solar Cells which were Selenium based were not very efficient but hinted to the possibilities of the technology if better materials could be found. When Silicon Solar Cells made their debut, the viability of converting Light into electricity now became a useful but expensive means for generating electricity from light. In the early days of Silicon based Solar Cells the efficiency of Solar Cells was about 10 percent. With the advent of Amorphous and Polymorphic Solar Cells efficiencies are now close to 41%.
How Do Solar Cells Work
Let us first define what a Solar Cell is. Electricity can be created by generators, chemicals, heating of dissimilar metals and by direct conversion of Sunlight. The Silicon Solar Cell is an electronic device that uses two types of Silicon to produce electricity strikes the material. This is possible because Photovoltaic Cells take advantage of the Particle Nature Of Light. Light has two properties Waves & Particles and the particle nature of light which is called the Photon the excitation element of a Solar Cell.
As Photons strike the Silicon Material current flows producing electricity; without getting to technical I’ll explain the conversion process that takes place when light strikes a Solar Cell.
A Silicon Solar Cell is not pure Silicon, Pure Silicon is a poor conductor of electricity as a result impurities are added (referred to as doping) to allow for the free movement of electrons which results in current flow. When these impurities are added
1000
to the Silicon extra electrons are added to the material that are easily knocked loose by Photons hitting the Silicon.
Now as many may know for there to be current flow, you need an anode and cathode. This is accomplished in a Silicon Solar Cell by doping some Silicon with N-Type material like Phosphorus and P-Type material like Boron.
When the P and N doped materials are in close proximity we now have a circuit that will generate electricity when a Photon strikes the Solar Cell. By combining lots of Solar Cells in parallel and series we are able to create an array of Solar Cells that will produce the voltage and current that you require to power your electrical devices.
Since we can stack many Solar Cells together we can develop Solar Panels of any size to generate enough power to supply the electricity needs of a home. Though Solar Panels at one time were very expensive and beyond the reach of homeowners; over the last ten years prices for Solar Cell panels have dropped dramatically. Thus making it affordable for homeowners to use them to generate electricity for their homes.
Better yet for those that like to do things themselves you can assemble your own Solar Panels and save a bundle while seeing a faster return on your investment. For instance a Do-It-Yourself individual can assemble a Solar Panel for about $200 which saves you a few thousand over a commercial Solar Panel.
For homeowners who want to invest in Green Technologies like Solar & Wind the Federal and Local Government offers Tax Credits and Subsidies. This means that an investment in Green Technology puts money in your pocket, ups your homes value and reduces your dependence on polluting Fossil Fuels the Polluting Fossil Fuels that are responsible for Global Warming.
Final Thoughts
Solar Energy, our most plentiful renewable energy is non polluting unlike the current mix of Carbon Based Fossil Fuels and is available to us for as long as the Sun continues to shine. Fossil Fuels on the other hand are obtained from deposits laid down millions of years ago are a finite resource that won’t last forever.
As the technology continues to improves and Solar Cell efficiencies continue increase the cost of implementing Solar Energy Technology will drop even more than they are today. This can not be said of Fossil Fuels; if 2008 is an example of what’s to come Fossil Fuels will become more expensive as demand for them increases and their availability becomes scarce.

So do you want to know about photovoltaic solar cells?
I understand how a lot of people use or want to use solar energy to power their home. For those of you who are using it then you already know this, and for those of you who are considering it, I can tell you it is very effective, and it saves a lot of money.
Photovoltaic cells, are called so because they are made of photovoltaic material, they are also known as solar cells. These cells are used to capture solar radiation, in other words, the sunlight and convert it into electricity.
All solar panels are made from photovoltaic cells, that is why they are called photovoltaic panels. The only difference is that these cells can be made with various methods and technologies.
Get this- Photovoltaic production is the fastest growing energy technology in the world, it has been increasing by an average of 48 percent each year since 2002.
In the past few years new innovative techniques have been created to enhance the production of solar cells and to make them more affordable.
Do you know how traditional solar panels look like? You must have seen them on some roof tops, right?
Well, the ones you usually see are the old generation of panels; solar panels are now made with much more advanced technology that can integrate the Photovoltaic cells in different material.
Here are some examples of the new Photovoltaic cells:
1- Thin film solar cells
2- Printed solar cells
3- Solar roof tiles
4- Shingles
Warning: The best method to convert energy from the sun into electricity is by using photovoltaic cells.
Photovoltaic cells are the main component of any solar panel!

Positional Cloning Approach Expedites Gene Hunts
For most scientists, searching for a disease gene means years of laboring over the mapping, cloning, and sequencing processes and considerably less time actually studying the gene and its function.
But this should soon change. A new approach called “positional candidate” is rapidly coming of age and should streamline the process of identifying disease genes within the next few years.
Based on the growing body of genome resources, the positional candidate strategy lets researchers combine information about a gene’s chromosomal location with increasingly detailed genetic and physical maps, allowing for easier identification of a potential causative gene.
According to the latest data, positional candidate studies already have led to the identification of over 50 disease genes. Commenting recently in Nature Genetics, NIH National Center for Human Genome Research Director Francis Collins stated that this more efficient approach is a major reason that positional cloning is moving from the “perditional to traditional” way of finding disease genes.
Strategy Saves Time
One of the most intriguing uses of the positional candidate strategy is the recent identification of the gene causing achondroplasia (ACH), a common form of dwarfism.
The ACH gene story began in 1991 during the marathon race for the gene responsible for Huntington’s disease. That year, a group at the University of California, Irvine, reported that it had isolated an interesting cDNA that mapped to the middle of the chromosome 4 subregion possibly containing the Huntington’s gene.
This was exciting news. The group, led by John Wasmuth, and other members of the Huntington’s Disease Collaborative Research Group had spent nearly 8 years stalking the Huntington’s gene in an initiative that Science once described as “a nightmare of false leads, confounding data, and backbreaking work.”
The backbreaking work went on. Later studies failed to show that the gene, called FGFR3, played any role in Huntington’s. Having already deposited the nucleotide sequence for FGFR3 in GenBank ™, Wasmuth’s group continued to search along the tip of chromosome 4.
The Irvine scientists did not realize it at the time, but this work with the FGFR3 gene would give them a head start later in the hunt for the gene involved in ACH.

/>
Last year, three laboratories reported that linkage studies had localized the ACH gene to a 2.5-Mb stretch on the tip of chromosome 4, the region where the FGFR3 gene resides. This time, investigators had no need to construct clones of the DNA region or design complex disequilibrium studies. With the sequenced FGFR3 gene as their candidate, they acquired patient DNA samples and developed PCR primers to test for possible mutations.
Within a matter of weeks, the Irvine scientists got their answer: 15 of 16 people with ACH had the same point mutation in the FGFR3 gene.
Positional Candidate Strategy Becoming Widely Used
The positional candidate approach relies on a three-step process that saves time and effort: (1) localizing a disease gene to a chromosomal subregion, generally by using traditional linkage analysis; (2) searching databases for an attractive candidate gene within that subregion; and (3) testing the candidate gene for disease-causing mutations.
Not so long ago, accessing a database of mapped genes seemed as futuristic as boarding the Starship Enterprise. With the tremendous progress in mapping human and mouse genomes and improving gene-discovery techniques, the positional candidate strategy already has amassed an impressive list of gene discoveries.
Since 1990, scientists have used this approach to find genes implicated in such conditions as Marfan syndrome, inherited nonpolyposis colon cancer, retinitis pigmentosa, long QT syndrome, Jackson-Weiss syndrome, Crouzon syndrome, Alzheimer’s disease, and several others. As impressive as this list is, recent international mapping initiatives promise to put many more human genes on the map during the next few years and make positional candidate investigations even more successful.
In February of this year, Washington University and the pharmaceutical company Merck, Sharpe, and Dohme announced the first publicly available installment of 15,000 ESTs. Launched last summer, this ambitious effort is expected to process about 200,000 cDNAs over the next 18 months. Lawrence Livermore National Laboratory is arraying clones from a cDNA library generated at Columbia University.
Meanwhile, an international EST consortium is being coordinated at the Sanger Centre. It includes the Stanford University Genome Center, Wellcome Trust Centre for Human Genetics, Genethon, Washington University, University of Cambridge, and Whitehead Institute Massachusetts Institute of Technology. These groups joined forces to begin mapping 70,000 ESTs to 0.5-Mb intervals or better. To help speed this important initiative along, The Institute of Genomic Research donated primers for 15,000 ESTs.
Looking to the Future
Still, several challenges remain before positional candidate strategies become firmly entrenched. One concern is the need for a more comprehensive database of mapped genes. Although well over 4000 genes have been mapped, tens of thousands more must be identified to fill in blanks in the human genome.
At the same time, standard positional cloning efforts usually result in candidate intervals of 0.5 to 5 Mb, but mapping cDNAs to traditional somatic cell hybrids or by using FISH usually will not achieve this degree of resolution. Large-insert clone libraries or radiation hybrids may be needed to provide the necessary resolution.
Despite these challenges, both of which are now being addressed successfully, most experts are encouraged by the short-term success of positional candidate studies. “With all the cDNA activity alone, it seems likely that more than half the human transcripts will be placed on the human genome map in the next 18 months,” predicted Collins. “The effect on the success rate of the positional candidate approach should be profound.”

So do you want to know about the thin film solar panel? I understand how a lot of people want to use solar energy to power their homes. Solar panels are a viable solar energy source, both environmentally and economically.
I am a green person myself; I use solar systems to power my own home. And guess what?
I was able to save a lot of money on my electricity bill, and so can you!
Now let me ask you a question- You all know the traditional thick panels, right?
Of course, you do. Most of you have seen these on many roof tops.
Get this- Thin film solar panels are the newer, thinner type of panel that has the potential to make solar energy much more affordable.
Thin panel versus thick panel
The main reason why solar units have not been widely affordable in the past is because thick panels are made of expensive materials, and they cost much to manufacture.
On the other hand, thin panels are made of much cheaper materials, and the cost of production is almost 3 times less than that of the first generation of panels, which means that they are much more affordable.
Thin film also means that the solar cell is smaller, lighter weight, and more flexible than traditional cells. Thin systems pack more wattage in less space.
Unlike thick panels that need a steel structure to hold them in place, thin film solar panels can be integrated into the roof or wall itself.
Warning: Thin film panels are very practical to use, there are small portable solar units that can be carried with you anywhere you go.
With new thin film solar panels the price of solar systems is coming down!
You can see available thin panels on the market by clicking here
You can still buy the components from your local hardware and do it yourself.

How may the Solar System effect our lives in the future?
Earth is part of the Solar System. It provides everything that allows us to exist. That isn't expected to change until the Sun begins its expansion to a red giant in about 1.1 billion years.
“When the Sun does begin to bloat up, it will go quickly, sweeping through the inner Solar System in just 5 million years. It will then enter its relatively brief (130 million year) helium-burning phase. It will expand past the orbit of Mercury, and then Venus. By the time it approaches the Earth, it will be losing 4.9 x 1020 tonnes of mass every year (8% the mass of the Earth).
But the habitable zone will be gone much sooner. Astronomers estimate that will expand past the Earth's orbit in just a billion years. The heating Sun will evaporate the Earth's oceans away, and then solar radiation will blast away the hydrogen from the water. The Earth will never have oceans again. It will eventually become molten again.
One interesting side benefit for the Solar System. Even though the Earth, at a mere 1.5 astronomical units, will no longer be within the Sun's habitable zone, much of the Solar System will be. The new habitable zone will stretch from 49.4 AU to 71.4 AU, well into the Kuiper Belt. The formerly icy worlds will melt, and liquid water will be present beyond the orbit of Pluto. Perhaps Eris will be the new homeworld.”
