From the Baghdad battery to the ark lights we now know the Ancients were charged. But what about the Pyramids? The paradoxical view that the Ancient Egyptians were primitive simpletons that would spend decades of energy and effort building some of the largest and longest standing structures of the ancient world, magnificent Architectural feats with flawless geometry that would have stretched the capabilities of builders and engineers even today, all to bury some dead guy, doesn't pass logical muster. So why were they built?

Statkraft has finally opened the first ever-built osmotic power prototype. This was inaugurated 24 November 2009 and performed by Royal Highness Crown Princess Mette-Marit of Norway.
Osmotic power is a very new concept of generating green energy. Energy is produced through the natural processes when fresh water is mixed with seawater. Starkraft has conducted research in the field of osmotic power for more than a decade. This new way of producing energy is totally eco-friendly and emission-free. It has even been predicted that osmotic power can in the near future account for a substantial supply of energy.
According to StatKraft CEO & President Bård Mikkelsen, the ability to anticipate climate challenges might soon be a reality. The use of technology where electricity can be generated from simply mixing water can make the future much greener.

As small island countries fight for a climate treaty that can ensure their existence, one archipelago has taken a more technical — and more direct — approach.
The Federated States of Micronesia filed a request with the Czech Ministry of Environment for a trans-boundary environmental impact assessment of the European country’s largest coal-fired power plant.
Prunerov isn't the worst polluter in Europe. But even as the 18th largest single source of carbon dioxide emissions on the continent, its emissions are 40 times the annual emissions of all Micronesia, according to Greenpeace.
A Czech law also makes it an open target for future climate change victims like Micronesia. ...

You might think of any given coal type as having relatively uniform properties: black, hard, carbon filled, and so on. However, dangerous mineral constituent concentration do vary widely; and, emissions of toxic constituents also vary greatly depending upon the design and operation of a combustion source. For example, some coal has trace levels of fluorides, while other deposits have highly hazardous levels of toxic fluorine compounds. The same is true for mercury, for arsenic, and for uranium and its radiological decay products. Relative to the radiological hazard, anecdotal evidence has emerged in India of children suffering from exposure to radionuclides associated with coal fired electricity production.You might think of any given coal type as having relatively uniform properties: black,... more
A new type of nuclear reactor that is designed to be manufactured in a factory rather than built at a power plant could cut construction times for nuclear power plants almost in half and make them cheaper to build. That, in turn, could make it possible for more utilities to build nuclear power plants, especially those in poor countries. The design comes from Babcock and Wilcox, a company based in Lynchburg, VA, that has made nuclear reactors for the United States Navy ships for about 50 years.A new type of nuclear reactor that is designed to be manufactured in a factory rather... more
Within two years, thousands of people will be preparing their dinner and heating their homes using methane gas extracted from human waste.
The energy company behind the scheme say the 'sewage works gas' will be clean, environmentally friendly and indistinguishable from the North Sea variety.
The pilot biogas conversion plant will be built at Britain's second biggest sewage works in Manchester and could generate enough power for 5,000 homes by 2011. Other plants are expected to follow - eventually producing sewage gas for hundreds of thousands of people.
Caroline Ashton, the company's biofuels manager, said: "Sewage treatment is a 24-hour process so there is an endless supply of biogas. It is a very valuable resource and it's completely renewable.' No sh*t.
Although the gas comes from human waste, it is hygienic to use for cooking.
It gives a whole new meaning to cooking with 'natural' gas.Within two years, thousands of people will be preparing their dinner and heating their... more
When I read this article by Allison Potter it supplied me with some hope. She asks many of the questions we ask here as to how we can get the attention of our decision makers.
As is posted on my web site:-
'We face many challenges in the global community brought on by practices and lifestyle choices made collectively over the last few decades.
Some choices and outcomes we may view as out of our control, made by our political leaders and the masters of Industry and Commerce. This view has been our choice and their decisions are with our agreement.
The future will be our choice also.'

Our political MASTERS are not listening to logic.
Not only are their policies shaped by corporate manipulation, the Oil & Gas Industry the Coal Industry, the multinationals, they are guided in their flawed thinking by advisors that have corrupt self-serving agendas to promote.
In the final and ultimate socratic irony, they stumble towards their decisions as to mans future, with the economic advice of experts, that can only count to 20 by removing their shoes.
When will they start listening to logic?

Good news for the environment.
The Bush administration said Wednesday that it was abandoning its pursuit of two proposed regulations relaxing air-pollution standards for power plants, surprising both industry and environmentalists by ending its pursuit of one of the last remaining goals set out by Vice President Dick Cheney’s Energy Task Force in 2001.Good news for the environment. > The Bush administration said Wednesday that it... more
The Bush administration is moving to adopt rules that would loosen pollution controls on power plants, by judging the plants on their hourly rate of emissions rather than their total annual output, people familiar with the matter said.
Under current policy, power plants that make upgrades to operate longer and increase emissions must install pollution-control equipment.
The proposed rules, which seek to make it easier for older power plants to extend their life span and upgrade without installing costly new equipment, are tied to an hourly rate of emissions. As long as a power plant's hourly emissions stay at or below the plant's historical maximum, the plant would be treated as if it were running more cleanly, even if its total annual emissions increased as plant operators stepped up operations.

For a newly hatched striped bass in the Hudson River, a clutch of trout eggs in Lake Michigan or a baby salmon in San Francisco Bay, drifting a little too close to a power plant can mean a quick and turbulent death.
Sucked in with enormous volumes of water, battered against the sides of pipes and heated by steam, the small fry of the aquatic world are being sacrificed in large numbers each year to the cooling systems of power plants around the country.
Environmentalists say the nation's power plants are needlessly killing fish and fish eggs with their cooling systems, but energy-industry officials say opponents of nuclear power are exaggerating the losses.
The issue is affecting the debate over the future of a nuclear plant in the suburbs north of New York City, and the facilities and environmentalists are closely watching the outcome here to see how to proceed in other cities around the country. The U.S. Supreme Court is expected to rule this term in a lawsuit related to the matter.
The issue's scope is tremendous. More than 1,000 power plants and factories around the country use water from rivers, lakes, oceans and creeks as a coolant. At Indian Point plant in New York, the two reactors can pull in 1.7 million gallons of water per minute. Nineteen plants on or near the California coast use 16.3 billion gallons of sea water every day.
Most of the casualties are just fish eggs, and for many species, it takes thousands of eggs to result in one adult fish. The U.S. Environmental Protection Administration, which counts only species that are valuable for commerce or recreation, uses various formulas and says the number of eggs and larvae killed each year at the nation's large power plants would have grown into 1.5 billion year-old fish.
Environmentalists note that even fish that die before maturity contribute to the ecosystem as food for larger fish and birds, and as predators themselves on smaller organisms. But once they've gone through the power plant, they become decomposing detritus on the river bottom and have moved from the top to the bottom of the food chain, said Reed Super, an environmental lawyer specializing in the federal Clean Water Act.
"This is a really significant ongoing harm to our marine ecosystem," says Angela Haren, program director for the California Coastkeeper Alliance in San Francisco.
Technology has long existed that might reduce the fish kill by 90 percent or more. Cooling towers allow a power plant to recycle the water rather than continuously pump it in. New power plants are required to use cooling towers, but most existing plants resist any push to convert, citing the huge cost and claiming that most fish eggs and larvae are doomed anyway.

Beneath the gargantuan grey boiler towers of Schwarze Pumpe power station which pierce the skies of northern Germany, a Lilliputian puzzle of metal boxes and shining canisters is about to mark a moment of industrial history.
This mini power plant is a pilot project for carbon capture and storage (CCS) - the first coal-fired plant in the world ready to capture and store its own CO2 emissions.
Next week the pilot - an oxyfuel boiler - will be formally commissioned.
A cloud of pure oxygen will be breathed into the boiler. The flame will be lit. Then a cloud of powdered lignite will be injected.
The outcome will be heat, water vapour, impurities, nine tonnes of CO2 an hour… and a landmark in clean technology.
Because the CO2 will then be separated, squashed to one 500th of its original volume and squeezed into a cylinder ready to be transported to a gas field and forced 1,000m below the surface into porous rock where it should stay until long after mankind has stopped worrying about climate change.
This is the technology once lavishly described by the former UK Chief Scientist Sir David King as "the only hope for mankind"; and the plant operators, Vattenfall, have worked furiously for two years to get the pilot running.
"We are very proud - we think this is the future for coal," says Vattenfall's Hubertus Altmann.
They funded the 70m-euro project themselves because they wanted to lead a technology they believe solves the conundrum of providing energy security through plentiful coal supplies whilst avoiding the CO2 emissions officially blamed for climate change. ACCESS ALL AREAS
In video: Inside the CCS plant
Green-carpeted marquees are currently being furnished for the guests who will swell the applause at the grand inauguration. But big questions hang over this technology overall, particularly over where the CO2 will be stored and who will pay the high costs of building and running the CCS plants.
The EU wants to see 10-12 full-scale power plants demonstrating CO2 capture within the next few years, but although a number of other firms will soon join the race with pilot projects, no full-scale CCS coal plant has yet been commissioned.
The British government has promised a decision in October on how it will fund a full-scale CCS in the UK. It hopes to avoid landing the taxpayer with the bill, but questions over CCS funding in Europe are as yet unresolved by the European Commission and the European Parliament.

Researchers at Kyushu University in Japan are developing a large-scale at-sea power plant combining photovoltaics and windmills designed to match the output of a nuclear power reactor.
The planned plant will measure two kilometers by 800 meters and will be equipped with light-emitting diodes that shine light into the sea to promote seaweed growth, which in turn will absorb carbon dioxide and attract fish. The plant will comprise hexagonal floating units that support a length of netting on which wind-power generators and photovoltaic generators measuring six square meters will be placed.
About 200,000 photovoltaic generator units are to be placed about a meter apart on the netting, with the hexagonal units positioned at both ends. The units have a channel running through them to allow seawater to pass through. Each group of units will generate about 300,000 kilowatts of electricity, which means the generating capacity of the three planned sets will be equal to that of a nuclear power reactor.
The researchers project that the cost-to-power generation rate of the plant is between ¥70,000 to ¥140,000 per kW (US$643-US$1,287), compared to the ¥200,000 per kW (US$1,838) for constructing a nuclear power plant.

One of the country’s largest builders of coal-fired power plants will give investors detailed warnings about the risks that global warming poses to its business under a deal with New York’s attorney general.
The agreement Wednesday between the attorney general, Andrew M. Cuomo, and the company, Xcel Energy of Minneapolis, is the first of its kind in the country. It could open a broad new front in efforts by environmental groups to pressure the energy industry into reducing emissions of the greenhouse gases that contribute to global warming.
Until now, advocates have largely relied on shareholder resolutions as a way of pushing the companies to reduce their carbon dioxide output and invest more aggressively in renewable energy sources like wind or solar power.
That effort has picked up pace, according to Ceres, a coalition of investors and environmental groups, with dozens of shareholder resolutions filed during the 2008 financial reporting season.
“This really takes it another step, by making it a settlement agreement that should have an impact across the industry,” said Dan Bakal, the director of electric power programs at Ceres.
Mr. Cuomo subpoenaed Xcel and four other companies last September, seeking to determine whether their efforts to build new coal-fired power plants posed risks not disclosed to investors, like future lawsuits or higher costs to comply with possible regulations restricting carbon emissions.
The attorney general’s office is still negotiating with the four other companies — the AES Corporation, Dominion, Dynegy and Peabody Energy. But Mr. Cuomo hopes that the agreement will help persuade other companies to follow in the footsteps of Xcel, which supplies natural gas and electricity to customers in eight states. Among utilities, Xcel is one of the nation’s largest producers of greenhouse gases and a major provider of wind energy.
Many coal-fired power plants have been proposed or are under construction across the country and environmental advocates have made it a priority to reduce their impact.
“This landmark agreement sets a new industrywide precedent that will force companies to disclose the true financial risks that climate change poses to their investors,” Mr. Cuomo said in a statement. “Coal-fired power plants can significantly contribute to global warming, and investors have the right to know all the associated risks.”
The agreement represents another novel use by Mr. Cuomo of the Martin Act, a powerful tool that allows the attorney general to bring criminal as well as civil charges. Mr. Cuomo’s predecessor, Eliot Spitzer, used the law to vastly expand the office’s investigations of suspected Wall Street malfeasance.
Now Mr. Cuomo has turned it into a de facto form of environmental enforcement, too. For energy companies, including those based far from New York, he is able to claim jurisdiction because they issue securities on Wall Street.
The agreement with Xcel requires the company to analyze the likely effects on its business of current and future legislation or regulations in the states and countries where it operates and to disclose that information in its investor filings with the Securities and Exchange Commission.
Congress and many states are considering global warming legislation. Ten states stretching from Maryland to Maine, including New Jersey, New York and Connecticut, have struck a deal to cap emissions and allow trading of pollution allotments among producers.

repost this link with more creativity if you wish.
Georgia, and other states in the Southeast are learning a lesson that communities on the Hudson River in New York know well: burning coal the old fashioned way costs the river environment, not just the air.
By now, everyone's familiar with the list of pollutants that spew from coal-fired power plants, including the compounds that form ozone, smog and acid rain; those that make our fish contaminated with mercury; and those that fill the atmosphere with greenhouse gases, fueling global warming.
But coal-fired power plants -- along with nuclear and other fossil fuel plants -- also use a lot of water. Typically, this water is sucked in to a plant, used to cool condensers and then flushed back into the river or lake on whose banks the plant sits. In the process, millions of fish, fish eggs, fish larvae and other aquatic life can be killed, and heated water discharged can cause ecological problems downstream as well.
The Hudson River has been ground zero -- for 30 years -- in the fight environmentalists have waged to have old plants upgraded, and have new plants built to use minimal water. Most plants built today use a fraction of the water old plants use, but the Environmental Protection Agency has resisted ordering upgrades on older plants.
Upgrading plants is not cheap. Not by a long shot. But the drought highlights another facet of the issue: It isn't just about fish. It's about people. When drought makes water scarce, it helps if your drinking water needs don't have to compete with your electricity needs.
With 45% of our country already in some stage of drought with urbanization, pollution, and substandard infrastructure causing waste, it is not feasible to continue pushing for new coal and nuclear power plants that will waste more water and endanger marinelife. That money could be better spent on altternate energy sources that conserve water and on upgrading old plants to use less water.

This is a short statement concerning the inflated use of "Emission-free Energy" or "CO2-neutral Energy" on this side, as well as on others. Let me brake it to you:
There is absolutely no way to produce energy without setting free CO2 (or equivalent gases).
This includes renewable energies like wind, solar or water and espeacially the non-renewable atomic power.
The reason? Even for the production of a solar-panel you will need energy. This energy will presently come from non-renewable sources. The production of concrete (which is important for building dams) will produce greenhouse gases and the production of enriched uranium consumes so much energy, that it renders the whole process of power production rather uneffective. Here is a ranking of the CO2-emissions for popular types of energy producing plants:
Brown Coal 1153 g CO2 / kwh
Black Coal 949 g CO2 / kwh
Natural Gas 428 g CO2 / kwh
Water 40 g CO2 / kwh
Nuclear Power 32 g CO2 / kwh
Solar Power 27 g CO2 / kwh
Windpark 23 g CO2 / kwh
Biogas -409 g CO2 / kwh
These are figures for pure energy production (except Biogas). Some forms of Power Plant can get more productive by around 1/3rd if they produce heat at the same time (this includes Brown and Black Coal and Natural Gas). Solar Power is only productive (in CO2 terms) if produced in suitable areas (in Germany it has a footprint of about 100 g CO2 / kwh).
