    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 : e need to get real about both global warming and the fact that oil supply is only ever going to diminish in future. To me, these are the biggest problems we face and should be accorded governmental priority accordingly. For a variety of reasons I don't see that happening. Maybe we need to wait until our reefs are bleached, Cane Toads hop around Martin Place like they do already in Brisbane, and fuel has reached $200/barrel for the penny to drop! What a shame.

    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 : ence 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.

    • thenden commented : r, and more humid, because of global warming. Meaning - people will need increasing amounts of AC to live well. As I come from the country of Norway, which usually is cold, but sometimes is somewhat warm, I know a little about ACs, as we use them for pumping heat inside, to save electricity. (1kW of electric power can move up to 4kW of heat, reducing energy consumption down to 1/4 with heat pumps) Because our temperatures can go down to -20, even to -40 and lower in the winter, thus our building codes are very strict about insulation in the walls to keep the heat inside. In the summer, those who have heat pumps, can run them as regular ACs, as a "bonus", as even 28-29 degrees celsius and strong sun can be hot for us farangs... However the insulation can work the other way around, to keep the heat _outside_! I have never seen this way of saving energy being discussed anywhere, however insulating a house in a hot country, will save a lot of energy, because you will lessen the need for AC to keep the inside cold, _a lot_! I notice that just one room in a typical two floor house in a gated community, meaning - house very nice after thai standard, needs one AC per room to keep cold. And when you turn the AC off, the room will get warm in less than 10 minutes, because there is no insulation in the walls. Eg. the temperature will rise from perhaps 24 to 30 degrees in just 10 minutes! In Norway, say if the electric power goes out, and the house has no furnace or oil burner, only electric heating, and it is for example -10 celsius outside, it would probably take 4-5 hours before the 22 degree inside temperature drops about the same, about 6 degrees. With variations due to type of house, of course, condo vs big house, old house, new house etc. Anyway, shorter power cuts are never a problem regarding the loss of heat inside, while here in Thailand, only a few minutes without power, and you will be sticky and hot! Typically only 1-2 heat pumps are enough to heat a large villa house in Norway, though some regular electric panel owens are used as backup, because the heat pumps will not work so well when the temperatures outside goes down to -20C typical in the coldest 1-2 months of the winter. Meaning - if a house in Thailand or any other hot country was insulated as well as in Norway (10-15 cm of glass or stone wool inside the wall), only maybe one large AC, with help of a ventilation system, would be enough to cool down one house! The windows obviously should be two or three layers insulating ones also, but that would depend on if you need to look outside much or not, because insulating windows are very expencive, while stone wool is cheap, anyway some sort of film to reflect sunlight would be advisable, so the windows don't leak too much infraread radiation into the house. If every house could use only one - 1 - AC instead of one per room, perhaps 4-5 ACs in a large family, it would mean a HUGE energy saving for not only Thailand, but any warm or hot country on the planet, and lessen the need for more power plants considerably, probably eliminate the need whatsoever! (Additionally, scientists believe that the eruption of a supervulcano, is the less rarest of all threats towards the humanity, rarer than asteroids. Not unthinkable in a period of say, 100 years. Meaning, having a well insulated house, and an AC, which also can be made to work as a heat pump, will be helpful, if the temperature ever should happen to sink to low levels even in a hot country, until the atmosphere clear up again in a few years.)

    cool kids and their motorbikes, new trend !?!

    By pachangamac042, Created on: 28/11/2008, Last updated on: 12/02/2009

    » There is a brand new trend in the village I stay up here near Chaiyaphum. Young people strip their motorbikes of everything “you don’t really need” like; lights, protections, exhaust pipes, silencers, mirrors and so on and then go on the streets an “do the monkey” on their bikes, specially...

    • Sean Moran commented : Certainly does defy logic in the context of multitasking operations at those sorts of decibels, but motivation itself is compromised by the removal of a tuned length extractor (US Eng. header) from a high-compression engine as well ?!? It's meant to be built at a certain length and radius so that a sine wave between the exhaust valve and the end of the pipe actually assists the rate of pollution and resultant global-warming as the valve opens over each cycle. It's not going to make the bike any quicker to remove the exhaust unless it's blocked up with buffalo turds or something. Logic and Chaiyaphum might be a bit of a chin scratcher though. Lonely Planet 2004 if I remember, mentioned that most Thai mattayom students couldn't pin the Chaiyaphum tail on the elephant's head. I used to use it on classroom know-it-alls all the time and three times out of four they won't get it until you draw the regions and add in Petchabun. Only driven through once and had lunch on the way back the next day. Very peaceful sort of place by the look of it. Have you heard any new hit songs on the radio about someone riding around on a motorbike with no muffler installed? Maybe it's the latest Lydia song behind the craze?

    Climate change

    Learningpost, David Canavan, Published on 05/01/2010

    » You will struggle to find anyone who has not heard the terms "climate change", "global warming" and "greenhouse effect". Recently, there was a climate change conference in Copenhagen. It was attended by many world leaders, who sadly didn't achieve much in the way of future reductions of carbon emissions. But what exactly is climate change? Let's explore the question.

    Why the Y2K threat was very real

    » To this day I still sometimes read about the Y2K bug and how it was a hoax. I sometimes see it likened to all manner of conspiracies. So here is the truth. I was involved in the Y2K mitigation program and it was a real issue. Jan 1, 2001 and other dates like 2010 were real issues and in fact they are still having an effect today.
