After years of warning the world about global warming and its dire consequences, Al Gore, the Nobel Prize winner, has finally taken the next, logical step. He is proposing a solution.

All major technologies for generating electric power from renewable energy sources are in various stages of development. Installations using wind power, solar energy, geothermal heat, and marine power have been started up and are slowly gaining a measurable foothold. At present, coal fired power plants generate the least expensive electricity. Therefore, market forces will never lead to the shutdown of the most egregious greenhouse gas emitters.

We must also be aware that it will be very difficult to satisfy our growing electricity demand by building only windmill farms, solar plantations, and geothermal power plants. Initially, the capital costs of these plants will be high, risks for meeting rated output will be well above average, and elevated maintenance costs will be a common experience.

Electric power is a fleeting commodity and we have not yet developed technologies that are capable of storing large amounts of electric energy.It seems unavoidable that nuclear power generation must assume a more substantial role during the next decades. Nuclear power has become safer and public resistance to nuclear power plants is slowly receding. Nuclear power plants can be installed faster once we begin to rely more on standardized reactor designs.

Nuclear reactors with smaller capacities need to be built as replacements for coal fired plant boilers.Huge amounts of capital and much time can be saved if existing coal plants can be retrofitted with steam produced in nuclear reactors to replace coal fired boilers.

Retrofit reactors should become available in a very few, standardized designs and in sizes that fit up with the predominant sizes of coal fired boilers in use. While the US will be replacing, retrofitting, or shutting down its fossil fuel fired plants, it is an opportune time to prepare the US to regain its independence from foreign oil imports.Very soon, such activity can save the US more than one trillion dollars annually. Past experience shows that petroleum prices and consumption of transportation fuels will maintain their unstoppable growths. Ideally, the world will keep its oil refineries operating and will preserve the huge distribution systems that deliver high quality liquid fuels to all corners of the world. Replacement of transportation fleets, oil refineries, and liquid fuel distribution systems will cost too much and may break the economies of even the richest countries.

To protect against such looming, economic disasters, the US must take the lead and learn how to produce petroleum substitutes from biomass. Recent events have taught us that we must never again abuse arable lands to make ethanol or diesel from food crops.

Arid lands are abundant. Best of all, making petroleum substitutes from renewable biomass sources will not have to cost more than $50 per barrel.Building plants for the domestic production of electric power and of transportation fuels from renewable energies will make the US strategically more secure, will make us economically stronger, will reduce global greenhouse gas emissions by one quarter, will create a huge number of jobs, and will pay for itself by producing large, domestic revenues for many decades to come.

Dr. Hemsath recently published the book: CLIMATE CHANGE – GOLD RUSH OR DISASTER? For 50 years he has worked as scientist, process engineer, Corporate Vice President of R&D, Company President, CEO, and Inventor. He holds more than 60 US Patents. He is working on a new book: “THE SOLUTION FOR ENDING GLOBAL WARMING AND CLIMATE CHANGE”. Go to http://www.thermalexpert.com. The US must lead the world by example. No other country has the capabilities and the resources to rebuild its energy supply systems.

Many are taking a fresh look at geothermal energy. Geothermal energy is nothing new, no more so than many of the so-called renewable energies. Iceland has been powering their nation and heating homes for almost four decades with geothermal energy and heat. The perception may be that geothermal fields exist only in famously volcanic areas such as Iceland. And, there are geothermal power plants all over the world producing clean energy to millions of people including, Africa, Australia, New Zealand, Chile, Russia, the UK and the US, just to name a few. But that seems to be changing. This is due to many factors but the primary reason is the obvious one and the elephant in living room – global warming. Scientists have been warning people and policy makers for quite some time now but many weren’t listening. It seems that people are finally listening and, the search for alternative energy sources is in full swing.

Hydropower, solar, wind power, bio fuels, tidal and nuclear all have their up sides and down sides, some more than others. The advantages of geothermal are many: they deliver low cost electricity, produce very low emissions, are unaffected by changing weather, provide a continuous power supply (base load). And, geothermal power plants are scalable, meaning they can produce power for a small town or a large city depending on the size of the geothermal field and generating capacity of the plant. There are disadvantages of course. Geothermal power plants deal in very corrosive fluids which require special handling, these power plants do emit low levels of carbon dioxide, sulfur, nitric oxide and geothermal hot water can contain trace amounts of heavy metals such as mercury. But there are techniques and technologies that exist today that can mitigate most of these issues down to a negligible figure. But, the counter-argument is that very careful consideration must be given as to the potential of a field and that the size of the generating plant must not be too large as to sap the reserve.

This new technology is called Kalina and it is an advancement to the binary cycle geothermal plants in that it uses an ammonia and water mixture to produce steam to drive the turbines. Ammonia is used because it has a much lower boiling point than water. The Binary cycle type plants, in general produce much less emissions by use of a heat exchanger wherein the hot water from the ground heats a secondary fluid like isobutane, or in the case of Kalina, an ammonia mixture, which is vaporized to drive the turbine.

The bottom line is I believe we are going to be hearing a lot more renewable energy development in the coming years and that geothermal energy and geothermal power plants will be the hot technology. The potential is vast, the technology exists and the time is now. – David Brooks

Stable hardwood floors should neither be put in over a concrete slab nor beneath floor degree due to excessive moisture sensitivity. Unpleasant gaps seem when moisture dries and the floors contract within the winter heating months. The flooring increase and gaps disappear during summers. The wooden planks may buckle or cup because of excessive moisture. In view of those information, enough space ought to be left for expansion and wooden ought to be acclimated. Nail-down installations are most appropriate for these floors. The possibility of re-coating and refinishing increases the life and appearance of solid hardwood floors. Typically strong hardwood floors are made up of ash, maple, red oak and white oak.

Solid wood floorings are divided into three sub classes: strip flooring, plank flooring and parquet flooring. Thickness of strip flooring varies between 5/sixteen inch and ¾ inch. Obtainable widths are 1 ½ inch, 2 inch and a couple of ¼ inch. Though plank flooring is offered in thicknesses, width can range between 3 inches and eight inches. Parquet flooring has geometrical patterns which are created with wooden slats.

Hand-scraped hardwood floors are hand crafted. Character markings on handscraped hardwood flooring (hand sculptured floors) are a unique feature. These floors supply the best finishes for either the fashionable world look or the previous reclaimed wooden ground look. Both engineered and solid hand sculpted floors are sold. Beautiful handscraped hardwood flooring are very expensive. Engineered handscraped hardwood flooring are greatest suited for a construction erected on a concrete slab and in high humidity conditions. A number of corporations additionally market distressed hardwood flooring that has machine made markings in contrast to hand made markings in handscraped hardwood floor. Handscraped flooring is costlier than distressed model, however each floorings provide a rich look.

Hardwood floors should be cleaned with merchandise advisable by the manufacturer. Common use of a vacuum cleaner will clear filth, mud, grit and small stones that will spoil the finish. Welcome mats at the entrance for wiping feet before walking on the floor are of great assist in protecting the finish. When choosing furniture for you residence, do not purchase merchandise with sharp steel or wood legs to forestall denting and scratching. Use of furnishings coasters or felt protectors for all legs will stop scratching. Non-staining and wide rubber cups are a should for heavy gadgets like piano. The usage of a paste wax on the hardwood ground with a polyurethane finish damages the finish. Spills on hardwood flooring need quick attention. Clear them with a paper towel or damp white cloth and dry the area.
