    Solar Power

    By Anonymous, Created on: 29/03/2005, Last updated on: 31/03/2015

    » I dont understand why Thailand is not using the sun which is there 365 days/year. Can anybody tell me ? I am in the process of building a house but when it comes to solar energy i might have to import myself to only then be confronted with a high import tax on such products. And that while closing...

    • Anonymous commented : This forum looks like it's got some well informed individuals on it so I felt I needed to contribute. I have just bought a house in Nakhorn Prathom; it is fairly big and it is on a rai of land which gives me reason to believe there are numerous possibilities for using solar energy. The house is also raised up with a four foot gap under it i.e. in the shade all of the time. Could anyone give me soem straight forward advice as to how best utilize solar power. Also i could do with some approximate prices. Thanks all. Kaya

    • Anonymous commented : It appears that scalable solar energy may be here already. Nanosolar in San Jose California is claiming their thinfilm printed solar sheets can be purchased ata cost of 99 cents- US per watt. If this is the case you have the beginnings of the great energy revolution. With that kind of cost it would be ideal for homeowner to power both his home and his vehicle with solar electricity. Utilities could even provide hydrogen as fuel at reasonable prices by splitting it from seawater. The US in particular is sick of dealing with OPEC. It costs us over a billion dollars a day to try to maintain the continuance of that supply and what do we get-higher and higher prices from countries that continue to oppress their own people. Yep- scalable solar is coming.

    Nuclear Power for Thailand

    By Anonymous, Created on: 04/09/2007, Last updated on: 09/07/2014

    » The Prime Minister has explained the plan for a nuclear power plant to produce energy for Thailand and help Thailand move away from reliance on oil and gas. Thailand is a net importer of energy, getting much of its energy from the middle east at a huge cost to the country. Added to that the use of...

    • Wizard commented : To Thailand Minister Of Power Why I like Geo Thermal and Makes me exited when I wake up each day. Geothermal energy - natures heat from the earth - it is free and todays energy markets it beats the door down on environmental and economic advantage over fossil and nuclear energy sources. Geo Thermal Heat from the earth can be used as the biggest energy source in the modern World, from large Offshore power stations to small and relatively simple pumping systems. My Panda 1 design for 2500MW or enough power for large city of 1 million homes. This heat energy, geothermal renewable at source, can be found almost anywhere—as far away as remote deep wells in China and Indonesia and as close as the soil in our Garden. Tapping geothermal energy is an affordable and sustainable solution to reducing our dependence on fossil fuels, and the global warming and public health risks that result from their use. I wish that all Governments of this World would Try to take onboard for the benefits of the Country they serve and stride in new paths of Renewable HP Steam producing Generation investments. Three different types of power plants - dry steam, flash, and binary - are used to generate electricity from geothermal energy, depending on temperature, depth, and quality of the water and steam in the area. In all cases the condensed steam and remaining geothermal fluid is injected back into the ground to pick up more heat. In some locations, the natural supply of water producing steam from the hot underground magma deposits has been exhausted and processed waste water is injected to replenish the supply. Most geothermal fields have more fluid recharge than heat, so re-injection can cool the resource, unless it is carefully managed. Dry Steam Power A dry steam power plant uses dry steam, typically above 235°C (455°F), to directly power its turbines. Dry steam is steam that contains no water droplets. All of the molecules are in a gaseous, as opposed to liquid, state. Dry steam plants are used where there is plenty of steam available that is not mixed with water. This is the oldest type of geothermal power plant and is still in use today. Dry steam plants are the simplest and most economical of geothermal plants. However, they emit small amounts of excess steam and gases. The geothermal plants at The Green land Geysers are dry steam plants. Flash steam Flash steam power use hot water above 182 °C (360 °F) from geothermal reservoirs. The high pressure underground keeps the water in the liquid state, although it is well above the boiling point of water at normal sea level atmospheric pressure. As the water is pumped from the reservoir to the power plant, the drop in pressure causes the water to convert, or "flash", into steam to power the turbine and or generators. Any water not flashed into steam is injected back into the reservoir for reuse. Flash steam plants, like dry steam plants, emit small amounts of gases and steam. Flash steam plants are the most common type of geothermal power generation plants in operation today. Binary-cycle The water used in binary-cycle power plants is cooler than that of flash steam plants, from 107 to 182 °C (225-360 °F). The hot fluid from geothermal reservoirs is passed through a heat exchanger which transfers heat to a separate pipe containing fluids with a much lower boiling point. These fluids, usually Iso-butane or Iso-pentane, are vaporized to power the turbine. The advantage to binary-cycle power plants is their lower cost and increased efficiency. These plants also do not emit any excess gas and, because they use fluids with a lower boiling point than water, are able to utilize lower temperature reservoirs, which are much more common. Most geothermal power plants planned for construction are binary-cycle. Main Advantages Geothermal energy offers a number of advantages over traditional fossil fuel based sources. From an environmental standpoint, the energy harnessed is clean and safe for the surrounding environment. It is also sustainable because the hot water used in the geothermal process can be re-injected into the ground to produce more steam. In addition, geothermal power plants are unaffected by changing weather conditions. Geothermal power plants work continually, day and night, making them. a fantastic proposition to investors and from an economic view, geothermal energy is extremely price competitive in some areas and reduces reliance on fossil fuels and their inherent price unpredictability. It also offers a degree of scalability: a large geothermal plant can power entire cities while smaller power plants can supply more remote sites such as rural villages. The SPGAsia Concept is to use the old wellhead Platforms and Refurbish the old well bore hole with Heat resistance liner and introduce Topside Control in its Harness and Steam Process insure the safety of the sea water returns back to the Sea clean and Risk free. Typical costs are 400M/700M for each Plant offshore Gary B Edwards Managing Director Member International Geo Thermal Consultants Subsea Power Group Asia Co.,Ltd

    A small price to pay

    Database, Published on 20/01/2010

    » Your TOT board put huge red Xs across all the recent auctions and three billion baht worth of contracts to build a fibre-optic network for broadband Internet, and vowed to call new contracts; the decision followed remarks by Prime Minister Abhisit Vejjajiva over the high prices of some of the bids, and your TOT will be certain to write new terms of reference for new auctions; the rather complicated auction was run in portions, for various parts of the country, but luckily for TOT turned out to total 3.03 billion baht, a full 0.01 billion below the budget; now they will have to do it all again, and despite what Mr Abhisit says, prices do go up, don't they?

    Dysfunctional campaign

    Database, Published on 03/02/2010

    » Prime Minister Abhisit Vejjajiva announced that he expects third generation phone service before New Year's Eve; he then announced why there probably won't be any; in a speech to mark the fifth anniversary of the Magnificent Seven National Telecommunications Commission, Mr Abhisit set out the conflicting criteria he expects to see in Asia's last, most dysfunctional 3G campaign: service before the end of the year after fair bandwidth auctions that favour small Thai telecom operators; on one hand, "3G services can no longer be postponed," he insisted, but on the other, the NTC must bias bidding to favour a more competitive structure; the English translation of this speech: DTac of Norway and AIS of Shingapore have way too much market power now and 3G contracts must show that.

    Magic numbers

    Database, Published on 11/08/2010

    » A little over a month before companies are expected to fork over containers of cash at an auction, the actual rules for the sale of 3G licences are still unclear; the Magnificent Seven have insisted they will take up the gavel in the last week of September (Prime Minister Abhisit Vejjajiva said it would be on Sept 24) to auction three licences, supposedly worth 12 billion baht or some other invented number; but the National Telecommunications Commission (NTC) apparently isn't actually selling use of the bandwidth to the winning mobile phone companies, but just narrow permission to use it for 3G, meaning that 4G and so on are unknowns; in addition; the NTC's vague threats to keep out foreign companies has sent the bidders into a tizzy; the main question is whether the threat applies to current firms such as AIS of Shingapore and Dtac of Norway - or just Singapore Telecom, or what?
