The Rebirth of Newer Better Modern America Cities
The Idea of Harnessing and using Geo Thermal Energy in Major Cities across the U.S. is knocking on our door.
Can President Donald Trump inspire Americans to; Dear to Dream Big and Make America Great Again?
For centuries,; people around the globe have utilized the earth’s natural resources’ known as Geo Thermal Energy, along with other green and renewable natural energy such as wind and solar in various ways.
In recent decades there has been much buzz and interest in developing, harnessing, and using green energy. While solar and wind seems to have taken the lead and drawn the most interest, I feel we’ve overlooked what just may be the best and most practical Green energy of all “Geo Thermal Energy”. Wind and Solar Energy have their place, but I don’t feel they are any match for the potential of what Geo Thermal can do.
I’ve long been a fan of Geo Thermal energy, and intrigued by the Idea of harnessing the earths’ natural geo thermal energy and using it to create modern model 21st century cities throughout America. Take a moment and envision the landscape of America with numerous major cities and urban centers leading world through the 21st century and beyond with the use of this completely environmentally friendly renewable green energy; and America once again being that shining city on the hill to guild the rest of the world into a better tomorrow. The idea is not all that farfetched.
This Geo Dream Project, as I like to call it; if undertaken would be a huge stimulus and boost for the American economy and would create millions of jobs and put millions of American workers, back to work. It’s a no brainer and a win, win, win, idea and plan; and when finished would be capable of harnessing the Geo thermal energy that that lays beneath our feet. The result being many of our large cities and urban centers would be transformed into Green Cities, by using an energy form for HVAC heating and cooling comfort systems that is completely environmentally friendly.
Lets get you up to speed on the basic idea of what exactly Geo Thermal Energy is and how it works.
Our earth absorbs and retains, and stores much of the heat radiated from our sun. Below the frost line of the surface of the earth; lays an enormous reservoir of a clean, natural, environmentally friendly source of energy called GEO THERMAL (Geo meaning earth, Thermal meaning heat). And it’s just sitting there largely ignored, and untapped. If America committed to harnessing this natural wonder, the rewards of economic growth, prosperity and the stimulus it would provide for our economy would by an enormous asset and benefit for American workers.
There are two basic types of systems used to mine and harness Geo thermal energy: E.G.E.O, & GEO. The basic difference between Geo and E.GEO is that E.GEO (“ENGINEERED GEO THERMAL ENERGY”) is used to create electricity and generally involves Hydraulic fracturing, and the use of high pressure injection wells. Geo on the other hand uses what is known as Geo thermal open and closed piping systems and utilizes heat pumps, and heat exchanges, to create H.V.A.C. heating and cooling comfort systems. (Generally in commercial and residential settings and buildings) and does not require hydraulic fracturing. See example below.
Uses geothermal heat pumps to harness the steady temperatures just underground to heat and cool buildings, cleanly and inexpensively. There are two main types of Geo Thermal heat pump ground systems The Closed Loop System, and the Open system.
The Photos in this piece along with the explanation below is an excerpt borrowed from the Energy.Gov web site ( https://energy.gov/energysaver/geothermal-heat-pumps )
Most closed-loop geothermal heat pumps circulate an antifreeze solution through a closed loop — usually made of plastic tubing — that is buried in the ground or submerged in water. A heat exchanger transfers heat between the refrigerant in the heat pump and the antifreeze solution in the closed loop. The loop can be in a horizontal, vertical, or pond/lake configuration.
One variant of this approach, called direct exchange, does not use a heat exchanger and instead pumps the refrigerant through copper tubing that is buried in the ground in a horizontal or vertical configuration. Direct exchange systems require a larger compressor and work best in moist soils (sometimes requiring additional irrigation to keep the soil moist). Because these systems circulate refrigerant through the ground, local environmental regulations may prohibit their use in some locations.
This type of installation is generally most cost-effective for residential installations, particularly for new construction where sufficient land is available. It requires trenches at least four feet deep. The most common layouts either use two pipes, one buried at six feet, and the other at four feet, or two pipes placed side-by-side at five feet in the ground in a two-foot wide trench. The Slinky™ method of looping pipe allows more pipe in a shorter trench, which cuts down on installation costs and makes horizontal installation possible in areas it would not be with conventional horizontal applications.
Large commercial buildings and schools often use vertical systems because the land area required for horizontal loops would be prohibitive. Vertical loops are also used where the soil is too shallow for trenching, and they minimize the disturbance to existing landscaping. For a vertical system, holes (approximately four inches in diameter) are drilled about 20 feet apart and 100 to 400 feet deep. Into these holes go two pipes that are connected at the bottom with a U-bend to form a loop. The vertical loops are connected with horizontal pipe (i.e., manifold), placed in trenches, and connected to the heat pump in the building.
If the site has an adequate water body, this may be the lowest cost option. A supply line pipe is run underground from the building to the water and coiled into circles at least eight feet under the surface to prevent freezing. The coils should only be placed in a water source that meets minimum volume, depth, and quality criteria.
This type of system uses well or surface body water as the heat exchange fluid that circulates directly through the GHP system. Once it has circulated through the system, the water returns to the ground through the well, a recharge well, or surface discharge. This option is obviously practical only where there is an adequate supply of relatively clean water, and all local codes and regulations regarding groundwater discharge are met.
Hybrid systems using several different geothermal resources, or a combination of a geothermal resource with outdoor air (i.e., a cooling tower), are another technology option. Hybrid approaches are particularly effective where cooling needs are significantly larger than heating needs. Where local geology permits, the “standing column well” is another option. In this variation of an open-loop system, one or more deep vertical wells is drilled. Water is drawn from the bottom of a standing column and returned to the top. During periods of peak heating and cooling, the system can bleed a portion of the return water rather than reinjecting it all, causing water inflow to the column from the surrounding aquifer. The bleed cycle cools the column during heat rejection, heats it during heat extraction, and reduces the required bore depth.
So there you have it; the basic idea of GEO Thermal Energy systems.
Consider for a moment, cities like Boston or New York utilizing various closed loop Geo thermal ground and pond loop systems throughout those cities water ways, harbors, airports and the underground tunnel systems that host our metropolitan transit and subway systems as the main source of energy for HVAC heating and cooling comfort systems in numerous commercial and government buildings throughout those cities landscapes across the U.S.
By using a continuous closed loop system that travels through the cities lakes, harbors, Airports, and underground tunnels that our transit and subway systems use, a number of zones could then be established that could then be tapped into the main loop system to create a number of HVAC Zones for the heating and cooling comfort systems in a huge number of commercial and government buildings.
Think of it in terms of your own home hydrothermal baseboard heating system. The only difference is that the source is a clean renewable GEO Thermal Energy vs. a boiler or furnace that burns fossil fuels such as Natural gas or Oil.
A simple geo thermal heating and cooling system that would deliver massive amounts of energy to heat and cool entire cities; that would be Huge and awesome: Don’t you think?
A simple horizontal pond and closed loop system of some type of non corrosive plastic tubing laid on the floor of harbors and waterways and then connected and extended into the underground transit and subway systems; Which could then be transferred via heat pumps and heat exchange’s for HVAC heating and cooling comfort systems throughout the city for various commercial and government buildings in the area.
The result: A reconstruction and modernization of America’s metropolitan harbors, water ways, transit and subway systems with an additional Geo thermal closed loop system attached that could be used as a clean, environmentally friendly, renewable green energy that will carry America through and beyond this new millennium.
I thought this to be a great topic to discuss and analyze. It has huge potential and benefits for America’s economy and future and would love to hear your thoughts and ideas on this topic.
In my next post on this Topic I will give more detail on how exactly Geo thermal heat pumps and heat exchange’s work, function and provide the required energy needed to supply Buildings with HVAC heating and cooling comfort systems.
Peace to All
Over & out!
