He has a background as civil engineer and geoscientist. He has worked mainly within the oil and gas industry from the mid 1980s. He has written some few fictional novels as well as author of some professional litterature within oil and gas sector, he is now an editor of some web sites, mainly within the travel business.
Use the natural heat storage capacity of the earth or ground water to provide energy efficient heating and cooling
Geothermal heating and cooling equipment is readily available in the marketplace and can be installed by any qualified contractor. The process is two-fold in that it involves installing the indoor unit and method of delivery, whether forced hot air or hydronic, and the outside pipe loop. Loop installation can be planned concurrently with other construction activities, so the overall construction schedule should not be affected by choice of system. Some loops will require an additional permit. Geothermal equipment can be installed with equal ease in both new construction and remodeling projects.
The initial cost of a geothermal heat pump system varies greatly according to local labor rates, lot geology and size, type of system installed, and equipment selected. So, geothermal heat pump systems are more costly to install than air source heat pumps. For either system, the cost of installed ducts should be identical. Equipment costs can be 50-100% more expensive for a geothermal heat pump system when the circulating pump, indoor tubing, and water source heat pump are considered. This 50-100% premium translates to $1,000 - $2,000 for the equipment that supplies a 3-ton system.
The ground loop is generally the most expensive component of a geothermal heat pump system and is highly dependent on local labor rates and drilling conditions. An installed ground loop stubbed out in a home can cost between $1,000 and $3,000 per installed ton. Overall, one could expect to pay between $4,000 and $11,000 more for a 3-ton GHP system than for an air source heat pump system.
Geothermal heat pumps offer high efficiency and low operating cost. According to the EPA, geothermal heat pumps can save homeowners 30 to 70 percent on heating and 20 to 50 percent on cooling costs over conventional systems. This information, as well as, reports that have been made by builders who monitor their in-place systems indicate that heating and cooling savings can range between $358 and $1,475, annually.
Geothermal heat pumps offer high efficiency and low operating cost. According to the EPA, geothermal heat pumps can save homeowners 30 to 70 percent on heating and 20 to 50 percent on cooling costs over conventional systems. Geothermal heat pumps provide a high level of occupant comfort. There is a potential for utility bill savings, and many local utility companies provide incentives for investing in geothermal heat pumps.

Free Power Blueprint - Ronald Bronson Free Power Blueprint Review
By: Sally Jensen | 03/01/2010Ronald Bronson, an alternative energy enthusiast, has created a complete easy-to-follow kit so that you can easily create and set up your own free energy machine which works at zero point. The Free Power Blueprint kit is going to show you how to build a magnetic free energy generator, which is a device that increases energy efficiency and propels itself perpetually by using a series of magnets. This device, when properly implemented, can power your whole household for free.
Free Power Blueprint - Zero Point Free Energy
By: Sally Jensen | 03/01/2010Zero point free energy is the energy that remains when all other energy is removed from a system. It was used a hundred years ago to power cars. Now, it has re-emerged as a central part of the search for free energy. This includes three revolutionary technologies: wireless transmission of electricity, free electrostatic energy, and passive electrical propulsion.
Free Power Blueprint - Zero Point Energy Field Manipulator
By: Sally Jensen | 03/01/2010The zero point energy field manipulator or the gravity gun is a tractor beam of sorts that is able to pick up objects and manipulate them. It was originally designed for handling hazardous materials, but was primarily used for heavy lifting. The gravity gun can also use zero point to repulse objects held in its field, propelling them at high speeds, and effectively turning everyday objects into weapons.
Best Free Power Blueprint Download Review
By: Jason Ricks | 03/01/2010Do you want to learn about a suppressed method for generating absolutely free electric energy? If yes, then Ronald Bronson will teach you how. He will guide you step-by-step and teach you everything you need to know in order to create a magnetic free energy generator.
Zero Point Energy Generators - Free Power Blueprint
By: Jason Ricks | 03/01/2010Zero point energy generators make use of magnets to utilize energy. As we all know, magnets have a field that has power and unlike other forms of alternative energy, they do not need any input to produce power. Magnets have two opposite poles which will either attract or repel with another. When the magnets attract and repel each other, they create continual motion. This motion is called perpetual motion because it will generate power without ever stopping. It will generate an unlimited amount o
Tapping The Zero Point Energy - Free Power Blueprint
By: Jason Ricks | 03/01/2010Tapping the zero point energy is becoming more and more popular nowadays. In physics, the zero point energy is the lowest possible energy that a quantum mechanical physical system may have and is the energy of the ground state. It is the energy that remains when all other energy is removed from a system.
How to Create a Powerful Artificial Brain!
By: Said Benrida | 03/01/2010I hear a lot about artificial intelligence in computer sciences and their power. But still we can’t trust that intelligence because it can’t understand and find solutions to any problem neither answer like a human does. What about creating a powerful artificial brain that we can trust, it can understand, find solutions to all problems, execute any order and answer like a human can do, even better? Then let’s try so.
How to Create an Infinite Source of Water!

VIRUS MAKES CALL BY ITSELF ON CELLPHONES - A NEW WAVE OF ATTACKS TO COME
By: Stig Kristoffersen | 20/11/2009 | Cell PhonesAn increase in virus attacks has been seen globally in October 2009, and it is only the beginning. I warned about virus on the smart phones to become a growing problem as early as in May 2009. The attacks so far have been less malicious than just to prove that the cellphones are vulnerable to attacks through various ways. The fact that the cellphones are less protected than the PC's makes us believe what we see now is only a beginning. You should begin to check your phone bill more closely now

GOOGLE AIM FOR FASTER INTERNET WITH NEW PROTOCOL CALLED SPDY - REPLACING HTTP?
By: Stig Kristoffersen | 14/11/2009 | InternetGoogle development team has launched the news about a new communication protocol called SPDY - short for SPEEDY. They claim this will speed up the internet twice of the exisiting level with the traditional HTTP protocol. Google does not say SPDY will replace HTTP, but rather supplement it, and that SPDY is a layered application based on the HTTP protocol, only disregards some aspects of this pioner protocol HTTP.
WATER FOUND ON THE MOON - HUMAN FLIGHT TO MARS NEXT?
By: Stig Kristoffersen | 14/11/2009 | News & SocietyNASA claim they have found ice on the moon with their latest satellite LCROSS launched in June 2009. The impact its rocket Centaur and itself, have given the space scientists proof of ice in the impact crater of Centaur. This could be a milestone for space researchers as it would pave the path for human space travels to Mars within a decade.
