Bid to classify cloud formation
2009-06-02, BBC News
http://news.bbc.co.uk/2/hi/uk_news/england/somerset/8077787.stm

A cloudspotter from Somerset believes he has identified a new type of cloud. Gavin Pretor-Pinney, from Somerton, who also founded the Cloud Appreciation Society, wants recognition for what he has named the asperatus cloud. He said: "It looks quite violent - as if you are looking up from underneath the turbulent surface of the sea." Weather forecaster Michael Fish told BBC Radio 4's Today programme he thinks it is caused by a mixing of two air masses or the bottom of a storm cloud. Mr Pretor-Pinney, who wrote the Cloudspotter's Guide ... asked his cousin - who is a Latin teacher - for a word that means choppy or turbulent that is used to describe the sea to name the cloud after. "Asperatus comes from the Latin verb aspero meaning 'to roughen up' or 'agitate'," he said. "It was used by the poet Virgil to describe the surface of a choppy sea." Mr Fish said he was "quite amazed" by pictures showing clouds fitting Mr Pretor-Pinney's asperatus description. “There has been no change to the classifications of clouds since 1953 and maybe this should be considered now. I can offer two explanations - they are either the mixing of two air masses - very warm humid air and and very cold dry air and it is like oil and water - it doesn't mix. These clouds could be formed at the boundary of these two air masses. Or ... they could be the turbulent underbelly of one of the huge thunder clouds." Mr Pretor-Pinney said the pictures were sent in by cloud society members from all over the world and some of them said there was no storm activity or heavy precipitation in the area at the time.

Note: How strange that a new type of cloud is now appearing. What changes could be causing this new formation? For more photos of these most unusual new clouds, click here. Or visit the Cloud Appreciation Society, founded by Mr. Pretor-Pinney.

Wauseon plant to open Monday for 110-mpg car engines
2009-05-30, Toledo Blade (Toledo, OH's leading newspaper)
http://www.toledoblade.com/apps/pbcs.dll/article?AID=/20090530/BUSINESS03/905...

The man who drove his 20-year-old Mustang from Napoleon, Ohio, to Las Vegas and back last year on 39 gallons of fuel will open his first manufacturing facility Monday to allow others to get 110 miles per gallon. Doug Pelmear, owner of Horse Power Sales.net Inc. and Hp2G LLC, will hold an open house ... in Wauseon to begin manufacturing his revolutionary engine. The factory ... will be tooled to initially turn out 20 of Mr. Pelmear's custom engines per day with one shift of 25 workers. A Decatur, Ind., specialty car company, Revenge Designs Inc., has contracted with Mr. Pelmear to purchase 2,000 engines for use in a new vehicle it plans to unveil at the end of this year at the Los Angeles International Auto Show. The vehicle is to be called the Revenge Verde Super Car, which will use Mr. Pelmear's 400-horsepower engine and its 500 foot-pounds of torque to travel up to 200 mph and get 110 mpg - though admittedly not at the same time. "The engine is going to be a really great partnership with the car," explained Emily Levault, a spokesman for Revenge Design. "The idea behind this was to give people what they want while putting people back in their jobs." Ms. Levault said the Verde will be introduced as both a left and right-hand drive, so that it can be marketed around the world. Mr. Pelmear has said that he employs more precise tolerances and manufacturing techniques to decrease heat and energy loss and increase the efficiency of the internal combustion engine. He said he has more than quadrupled the industry average engine efficiency of about 8 percent.

A climate solution that's out of this world
2009-05-14, New York Times
http://www.nytimes.com/gwire/2009/05/14/14greenwire-a-climate-solution-thats-...

One of the newest energy lobbyists claims he has the answer to climate change: spaceships. The government has in its possession "extraterrestrial vehicles," lobbyist Stephen Bassett said. As in flying saucers. Imagine the power source, he said, behind a 30-foot wide saucer that weighs the same as a tractor-trailer yet hurtles through galaxies at 20,000 miles per hour. "What is the energy system operating that craft?" Bassett said. "They're not burning kerosene." Bassett ... is working for free as a lobbyist, representing the Hawaii-based Exopolitics Institute, an educational organization which describes itself as "dedicated to studying the key actors, institutions and political processes associated with extraterrestrial life." Bassett said he is less lobbyist and more political activist. "The UFO phenomenon is real," Bassett said. "The E.T. extraterrestrial presence is real." Bassett's been lobbying about seven months, targeting the science and technology, and defense and aviation angles. He added energy to his portfolio in a Senate filing last week. He has spoken to lawmakers in the past, Bassett said, but he's writing off lobbying Congress for now, calling the extraterrestrial issue "the third rail" of politics. Besides, he and other believers have a bigger name on their list. "Knowing that Congress could not act," Bassett said, "what we did was focus on the executive branch, the White House." Those who believe the truth is out there have been waiting for someone like President Obama to come clean about the government hiding information on extraterrestrials, Bassett said.

Note: What's highly unusual about this article is that there is not a note of ridicule. This may be a first for a UFO article in the New York Times.

A Battle to Preserve a Visionary’s Bold Failure
2009-05-05, New York Times
http://www.nytimes.com/2009/05/05/science/05tesla.html

In 1901, Nikola Tesla began work on a global system of giant towers meant to relay through the air not only news, stock reports and even pictures but also, unbeknown to investors such as J. Pierpont Morgan, free electricity for one and all. It was the inventor’s biggest project, and his most audacious. The first tower rose on rural Long Island and, by 1903, stood more than 18 stories tall. Tesla, who lived from 1856 to 1943, made bitter enemies who dismissed some of his claims as exaggerated, helping tarnish his reputation in his lifetime. Today, his work tends to be poorly known among scientists, though some call him an intuitive genius far ahead of his peers. He was widely celebrated for his inventions of motors and power distribution systems that used the form of electricity known as alternating current, which beat out direct current (and Thomas Edison) to electrify the world. Around 1900 ... inventors around the world were racing for what was considered the next big thing — wireless communication. [Tesla's] own plan was to turn alternating current into electromagnetic waves that flashed from antennas to distant receivers. The scale of his vision was gargantuan. Investors, given Tesla’s electrical achievements, paid heed. The biggest was J. Pierpont Morgan, a top financier. He sank $150,000 (today more than $3 million) into Tesla’s global wireless venture. But Morgan was [eventually] disenchanted. Margaret Cheney, a Tesla biographer, observed that Tesla had seriously misjudged his wealthy patron, a man deeply committed to the profit motive. “The prospect of beaming electricity to penniless Zulus or Pygmies,” she wrote, must have left the financier less than enthusiastic.

Note: This article underplays a number of things about Tesla. Morgan stopped funding him primarily because he eventually realized that there would be no way to charge for the electricity Tesla was generating. If successful, electricity would be available virtually for free to those supplied by his tower. Tesla was then shunned by the power elite and his rightful claim as inventor of the radio (not Marconi) was erased in the history books. As stated on the PBS website, "It wasn't until 1943 — a few months after Tesla's death — that the U.S. Supreme Court upheld Tesla's radio patent number 645,576."

Cold Fusion Is Hot Again
2009-04-19, CBS News
http://www.cbsnews.com/stories/2009/04/17/60minutes/main4952167.shtml

Twenty years ago it appeared, for a moment, that all our energy problems could be solved. It was the announcement of cold fusion - nuclear energy like that which powers the sun - but at room temperature on a table top. It promised to be cheap, limitless and clean. Cold fusion would end our dependence on the Middle East and stop those greenhouse gases blamed for global warming. It would change everything. But then, just as quickly as it was announced, it was discredited. So thoroughly, that cold fusion became a catch phrase for junk science. Well, a funny thing happened on the way to oblivion - for many scientists today, cold fusion is hot again. "We can yield the power of nuclear physics on a tabletop. The potential is unlimited. That is the most powerful energy source known to man," researcher Michael McKubre told 60 Minutes correspondent Scott Pelley. McKubre says he has seen that energy more than 50 times in cold fusion experiments he's doing at SRI International, a respected California lab that does extensive work for the government. McKubre is an electro-chemist who imagines, in 20 years, the creation of a clean nuclear battery. "For example, a laptop would come pre-charged with all of the energy that you would ever intend to use. You're now decoupled from your charger and the wall socket," he explained. The same would go for cars. "The potential is for an energy source that would run your car for three, four years, for example. And you'd take it in for service every four years and they'd give you a new power supply," McKubre told Pelley.

2,757.1 MPG Achieved at 2009 Shell Eco-marathon Americas
2009-04-19, CNBC News
http://classic.cnbc.com/id/30287740

Distance, not speed, was the goal this weekend on the track at the 2009 Shell Eco-marathon Americas(R), a challenge for students to design, build and test fuel-efficient vehicles that travel the farthest distance using the least amount of fuel. This year, more than 500 students from North and South America were on hand to stretch the boundaries of fuel efficiency. So who came out on top? The student team from Laval University, with an astonishing 2,757.1 miles per gallon, equivalent to 1,172.2 kilometres per liter, won the grand prize in the "Prototype" category. And in the "UrbanConcept" category - new to the Americas event this year - the team from Mater Dei High School took the grand prize by achieving 433.3 mpg, equivalent to 184.2 km/l. With 44 participating teams at track competition was steep. This year's challenge brought together a number of returning teams determined to beat the 2,843 mpg (1,208 km/l) record set by Mater Dei High School (Evansville, Ind.) in 2008, combined with a number of new teams adding fresh innovation and vehicle designs to the competition. "The Shell Eco-marathon is a platform for students to let their imaginations run wild," said Mark Singer, global project manager for the Shell Eco-marathon. "By encouraging these students to build vehicles with greater energy efficiency, we hope this will help inspire others; and together we can find solutions that will help meet the global energy challenge."

Note: Why so little media attention to this most exciting race for top gas mileage? And if high school students can build a car that gets over 2,500 mpg, what's up with Detroit? Could big business be suppressing, or at the very least ignoring these inspiring inventions?

China Vies to Be World’s Leader in Electric Cars
2009-04-02, New York Times
http://www.nytimes.com/2009/04/02/business/global/02electric.html?partner=rss...

Chinese leaders have adopted a plan aimed at turning the country into one of the leading producers of hybrid and all-electric vehicles within three years, and making it the world leader in electric cars and buses after that. The goal, which radiates from the very top of the Chinese government, suggests that Detroit’s Big Three, already struggling to stay alive, will face even stiffer foreign competition on the next field of automotive technology than they do today. To some extent, China is making a virtue of a liability. It is behind the United States, Japan and other countries when it comes to making gas-powered vehicles, but by skipping the current technology, China hopes to get a jump on the next. The United States has been a laggard in alternative vehicles. G.M.’s plug-in hybrid Chevrolet Volt is scheduled to go on sale next year, and will be assembled in Michigan using rechargeable batteries imported from LG in South Korea. China’s intention, in addition to creating a world-leading industry that will produce jobs and exports, is to reduce urban pollution and decrease its dependence on oil, which comes from the Mideast and travels over sea routes controlled by the United States Navy. Beyond manufacturing, subsidies of up to $8,800 are being offered to taxi fleets and local government agencies in 13 Chinese cities for each hybrid or all-electric vehicle they purchase. China wants to raise its annual production capacity to 500,000 hybrid or all-electric cars and buses by the end of 2011, from 2,100 last year.

A lesson for Detroit - Tata Nano
2009-03-31, San Francisco Chronicle (San Francisco's leading newspaper)
http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2009/03/30/EDTK16PF19.DTL

Don't dismiss the Nano as a small, poor man's car that will cause a mere ripple on the world market. The Nano is a radical innovation, with the potential to revolutionize automobile manufacturing and distribution. The tiny Nano incorporates three innovations, which together make it huge. First, the Nano uses a modular design that enables a knowledgeable mechanic to assemble the car in a workshop. Thus, Tata can outsource assembly to independent workshops that can then assemble the car on buyers' orders. This innovation not only removes costly labor from the manufacturer's side but also allows for distributed entrepreneurship on the dealer's side. Second, the low cost of the Nano comes from a combination of its no-frills design and its use of numerous lighter components, from simple door handles and bulbs to the transmission and engine parts. The lighter vehicle enables a more energy-efficient engine that gets 67 miles to the gallon. Third, at just 122 inches long, the Nano is one of the shortest four-passenger cars on the market, yet it allows for ample interior space. These innovations have enabled Tata to introduce the Nano at a base price of $2,000. The low price has triggered worldwide interest in the car and a surge of orders, even in a struggling auto market. The Nano has the potential of flourishing despite the recession or softening its sting because of its extraordinary low price. It's a radical innovation precisely because it is a poor man's car.

Torture tests say battery power's hardly nerdy
2009-03-30, Boston Globe
http://www.boston.com/business/technology/articles/2009/03/30/torture_tests_s...

Bill Dubé gets giddy when he talks about batteries and speed. After all, his 500-horsepower Killacycle electric motorcycle goes from 0 to 60 miles per hour in under a second. He claims it is the fastest electric vehicle on the planet. In October, the Killacycle traveled a quarter mile in 7.89 seconds, topping out at 174 mph, a record. Dubé, 56, an engineer and Rhode Island native whose day job is designing air chemistry instruments at the University of Colorado, is the bike's designer, owner, and builder. He is out to prove that electric vehicles do not have to be "nerd-mobiles." At the heart of electric vehicles like the Killacycle are the batteries. A123 Systems Inc., based in Watertown, sponsors the Killacycle and provides its battery. Dubé read about A123's lithium-ion battery technology in 2003 and decided to approach company officials. He thought drag racing was a great way to torture-test the company's innovative battery cells. "I told them I'll take the battery cells out to the drag strip and set a world record," he said. Electric-vehicle racing hit the start line about 15 years ago, when pioneers like Dubé began building the machines. "Bill is quite amazing and does pretty good promoting electric-vehicle racing in general," said Mike Willmon, president of the National Electric Drag Racing Association, based in Santa Rosa, Calif. The mission of the group, whose membership stands at 100, is to increase public awareness about the performance side of electric vehicles.

Navy scientist announces possible cold fusion reactions
2009-03-23, Houston Chronicle (Houston's leading newspaper)
http://www.chron.com/disp/story.mpl/front/6333164.html

A U.S. Navy researcher announced today that her lab has produced “significant” new results that indicate cold fusion-like reactions. If the work by analytical chemist Pamela Mosier-Boss and her colleagues is confirmed, it could open the door to a cheap, near-limitless reservoir of energy. Devising a fusion-based source of energy on Earth has long been a “clean-energy” holy grail of physicists. A small group of scientists has [tried] to produce fusion reactions at low temperatures. If such experiments did produce fusion reactions, they would generate highly energetic neutrons as a byproduct. These are what Mosier-Boss says her San Diego-based group has found. “If you have fusion going on, then you have to have neutrons,” she said. “But we do not know if fusion is actually occurring. It could be some other nuclear reaction.” Today’s announcement is based partly on research published by Mosier-Boss’ group last year in the journal Naturwissenschaften. The announcement may turn heads, given its stage at the American Chemical Society’s big meeting and the fact that the organization promoted it to science journalists in advance. “It’s big,” said Steven Krivit, founder of the New Energy Times publication, which has tracked cold fusion developments for two decades. “What we’re talking about may be more than anybody actually expected,” he said. “We’re talking about a new field of science that’s a hybrid between chemistry and physics.”

Cooking with the power of the sun
2009-03-13, KSL-TV (Salt Lake City NBC affiliate)
http://www.ksl.com/?nid=148&sid=5845295

People are looking for ways to trim budgets and cut down on energy use. There's a product heating up in Utah that does just that. It even helps a good cause. Don't underestimate the power of cooking with the sun. LaRue Howells first bought a Global Sun Oven a year ago to be prepared for an emergency, but now she uses it a few times a week, all-year round and shares her knowledge with members of her church. Howells said, "I can grab the solar oven and some food and take off if I needed to, and it's wonderful to have." She baked bread for us. The temperature outside was in the low 40s. "We baked bread when it was 17 degrees outside," she said. "The temperature outside isn't the issue, it's the sun." To control the heat of the oven, you adjust the angle of the oven to the sun. If you want to reduce the heat, you angle it away from the sun. One-third of the Sun Ovens sold in the U.S. are sold in Utah. Joe Crane, with Kitchen Kneads, said, "Just being prepared, self-sufficient brings a lot of peace of mind to people." Crane started to sell them nearly a year ago. "Temperature makes no difference," he said. "I've cooked at 5 below to 90 degrees in the summer time." All you need is sun, and cook times aren't much longer than with a conventional oven. As useful as we might find them, Sun Ovens are life sustaining in developing countries looking for solutions to deforestation and energy deficiency. Domestic sales help pay for ovens in Afghanistan, Nepal and South Africa. They cost around $300. Sun Ovens [use] no electricity and [burn] no fuels, meaning no emissions.

Oil producers running out of storage space
2009-03-03, MSNBC/Associated Press
http://www.msnbc.msn.com/id/29495753

Supertankers that once raced around the world to satisfy an unquenchable thirst for oil are now parked offshore, fully loaded, anchors down, their crews killing time. In the United States, vast storage farms for oil are almost out of room. As demand for crude has plummeted, the world suddenly finds itself awash in oil that has nowhere to go. It’s been less than a year since oil prices hit record highs. But now producers and traders are struggling with the new reality: The world wants less oil, not more. And turning off the spigot is about as easy as turning around one of those tankers. So oil companies and investors are stashing crude, waiting for demand to rise and the bear market to end so they can turn a profit later. Meanwhile, oil-producing countries such as Iran have pumped millions of barrels of their own crude into idle tankers, effectively taking crude off the market to halt declining prices that are devastating their economies. Traders have always played a game of store and sell, bringing oil to market when it can fetch the best price. They say this time is different because of how fast the bottom fell out of the oil market. “Nobody expected this,” said Antoine Halff, an analyst with Newedge. “The majority of people out there thought the market would keep rising to $200, even $250, a barrel. They were tripping over each other to pick a higher forecast.” Now the strategy is storage. Anyone who can buy cheap oil and store it might be able to sell it at a premium later, when the global economy ramps up again.

Electric motor polarizes opinion
2009-02-28, Toronto Star
http://www.thestar.com/News/Ontario/article/594471

Thane Heins ... has invented a technology that he says will put out more energy than it consumes. His invention, he boldly claims, offers a way to make electric cars that can travel hundreds of kilometres from the energy in a small, inexpensive battery. The Star first profiled Heins and his controversial invention a year ago. In a nutshell, he had figured out a way to eliminate the electromagnetic friction that typically limits the performance of an electrical generator – an effect known as “Back EMF.” Not only that, but he also learned how to redirect that magnetic energy so that, instead of causing resistance, it gave an electrical motor connected to the generator a significant boost. The result, as far as Heins was concerned, violated Lenz’s law or what’s often called the law of diminishing returns. For many, that equates to a perpetual motion machine, an impossible claim in the conventional field of physics. Within no time the story spread globally across the Internet, became chatter on blogs, and triggered a flood of email to this reporter’s inbox – some praising Heins for his determination, others calling the Star irresponsible for giving credibility to his claim. The story, love it or hate it, was the second-most read article on TheStar.com in 2008. Much has happened over the past 12 months. Through his Ottawa-based company Potential Difference Inc., Heins has been in serious talks with a designer of small wind turbines in Montreal, a senior engineer from a large utility in Turkey, and a small manufacturer of electrical equipment in Toronto.

Solar Panel Drops to $1 per Watt: Is this a Milestone or the Bottom for Silicon-Based Panels?
2009-02-26, Popular Mechanics
http://www.popularmechanics.com/science/research/4306443.html

A long-sought solar milestone was eclipsed on Tuesday, when Tempe, Ariz.–based First Solar Inc. announced that the manufacturing costs for its thin-film photovoltaic panels had dipped below $1 per watt for the first time. With comparable costs for standard silicon panels still hovering in the $3 range, it's tempting to conclude that First Solar's cadmium telluride (CdTe) technology has won the race. But if we're concerned about the big picture (scaling up solar until it's a cheap and ubiquitous antidote to global warming and foreign oil) a forthcoming study from the University of California–Berkeley and Lawrence Berkeley National Laboratory suggests that neither material has what it takes compared to lesser-known alternatives such as—we're not kidding—fool's gold. Even if the solar cell market were to grow at 56 percent a year for the next 10 years—slightly higher than the rapid growth of the past year—photovoltaics would still only account for about 2.5 percent of global electricity, LBNL researcher Cyrus Wadia says. "First Solar is great, as long as we're talking megawatts or gigawatts," he says. "But as soon as they have to start rolling out terawatts, that's where I believe they will reach some limitations." Even the current rate of growth won't be easy to sustain. Despite the buck-per-watt announcement, First Solar's share price plummeted more than 20 percent on Wednesday, thanks to warnings from CEO Mike Ahearn about the effect of the credit crisis on potential solar customers—as much as 10 to 15 percent of current orders might default.

Note: Solar energy costs have dropped consistenly and steadily over the past 30 years. In the late 1970s solar energy cost $100 per watt. The price will almost certainly continue to drop. The San Francisco Chronicle reported in 2005 that "the electricity currently provided by utilities ... averages $1 per watt." Why isn't it being trumpeted loudly worldwide in the media that solar energy is reaching parity with traditional energy sources? Could it be that powerful interests don't want solar energy to be competitive with oil and nuclear?

Exxon Mobil sets record with $45.2 billion profit
2009-01-30, Miami Herald/Associated Press
http://www.miamiherald.com/business/nation/story/879748.html

Exxon Mobil Corp. ... reported a profit of $45.2 billion for 2008, breaking its own record for a U.S. company. The previous record for annual profit was $40.6 billion, which the world's largest publicly traded oil company set in 2007. The extraordinary full-year profit wasn't a surprise given crude's triple-digit price for much of 2008, peaking near an unheard of $150 a barrel in July. Since then, however, prices have fallen roughly 70 percent amid a deepening global economic crisis. In the fourth quarter alone crude tumbled 60 percent, prompting spending and job cuts in an industry that was reporting robust, often record, profits as recently as last summer. Irving, Texas-based Exxon said net income slid sharply to $7.8 billion, or $1.55 a share, in the October-December period. That compared with $11.7 billion, or $2.13 a share, in the same period a year ago, when Exxon set a U.S. record for quarterly profit. It has since topped that mark twice, first in last year's second quarter and then with earnings of $14.83 billion in the third quarter. Revenue in the most-recent quarter fell 27 percent to $84.7 billion. The industry went into retrenchment toward the end of the year with demand falling. The company, which produces about 3 percent of the world's oil, said overall output fell 3 percent in the most-recent period. For the full year, Exxon Mobil's massive profit amounted to $8.69 a share, versus $7.28 a share a year ago.

Note: How can it be said that this record-breaking profit "wasn't a surprise," when ethically we would all expect the oil companies not to gouge consumers world-wide at the time when oil prices were artificially driven to record highs? Why should the oil companies be allowed to rake in huge profits causing the vast majority of us to suffer even greater losses at the gas pump? This is generally called gross profiteering. Shouldn't these "windfall profits" be taxed away?

No Furnaces but Heat Aplenty in ‘Passive Houses’
2008-12-27, New York Times
http://www.nytimes.com/2008/12/27/world/europe/27house.html?partner=rss&emc=r...

From the outside, there is nothing unusual about the stylish new gray and orange row houses in the Kranichstein District. But these houses are part of a revolution in building design: There are no drafts, no cold tile floors, no snuggling under blankets until the furnace kicks in. There is, in fact, no furnace. In Berthold Kaufmann’s home, there is, to be fair, one radiator for emergency backup in the living room — but it is not in use. Even on the coldest nights in central Germany, Mr. Kaufmann’s new “passive house” and others of this design get all the heat and hot water they need from the amount of energy that would be needed to run a hair dryer. “You don’t think about temperature — the house just adjusts,” said Mr. Kaufmann. His new home uses about one-twentieth the heating energy of his parents’ home of roughly the same size, he said. The concept of the passive house, pioneered in this city of 140,000 outside Frankfurt, approaches the [energy efficiency] challenge from a different angle. Using ultrathick insulation and complex doors and windows, the architect engineers a home encased in an airtight shell, so that barely any heat escapes and barely any cold seeps in. That means a passive house can be warmed not only by the sun, but also by the heat from appliances and even from occupants’ bodies. And in Germany, passive houses cost only about 5 to 7 percent more to build than conventional houses. New passive houses use an ingenious central ventilation system. The warm air going out passes side by side with clean, cold air coming in, exchanging heat with 90 percent efficiency.

Survey: Oil May Lose Top Rank as Cheapest Energy
2008-12-10, ABC News/Associated Press
http://abcnews.go.com/Business/wireStory?id=6432204

Over the next 20 years or so, oil and natural gas will lose top ranking as the world's most affordable energy sources, according to a survey of energy executives. Deeper wells in more inhospitable places, both political and geological, have altered presumptions of doing business in the oil patch. Nearly three out of four executives and managers surveyed last month by Deloitte LLP said oil and gas are the cheapest available energy sources for now, though only 23 percent believe that will be the case in 25 years. The sampling revealed a growing concern about the sustainability of oil and natural gas in the coming years. Future sources of fossil fuels, the cost of producing them and the price consumers will pay are some of the biggest uncertainties facing the industry. "Clearly, the oil and gas professionals involved in our survey are starting to think about the nation's transition to renewable energy and other alternative fuels," said Gary Adams, vice chairman of Deloitte's oil and gas practice. Of the executives interviewed by Deloitte, 53 percent said they think the U.S. could run out of reasonably priced oil within the next quarter century, and 56 percent said the world is likely to face the same scenario in the next 50 years. Three out of four said shifting away from the nation's reliance on fossil fuels for transportation needs is an appropriate goal for the country, yet most think the best alternative right now is natural gas. About 30 percent said electric plug-in vehicles are the most promising alternative.

Ocean currents can power the world, say scientists

A revolutionary device that can harness energy from slow-moving rivers and ocean currents could provide enough power for the entire world, scientists claim. The technology can generate electricity in water flowing at a rate of less than one knot - about one mile an hour - meaning it could operate on most waterways and sea beds around the globe. Existing technologies which use water power, relying on the action of waves, tides or faster currents created by dams, are far more limited in where they can be used, and also cause greater obstructions when they are built in rivers or the sea. Turbines and water mills need an average current of five or six knots to operate efficiently, while most of the earth's currents are slower than three knots. The new device, which has been inspired by the way fish swim, consists of a system of cylinders positioned [horizontally] to the water flow and attached to springs. As water flows past, the cylinder creates vortices, which push and pull the cylinder up and down. The mechanical energy in the vibrations is then converted into electricity. The scientists behind the technology, which has been developed in research funded by the US government, say ... the technology would require up to 50 times less ocean acreage than wave power generation. The system, conceived by scientists at the University of Michigan, is called Vivace, or "vortex-induced vibrations for aquatic clean energy".

The 10 big energy myths
2008-11-27, The Guardian (One of the U.K.'s leading newspapers)

There has never been a more important time to invest in green technologies, yet many of us believe these efforts are doomed to failure. What nonsense. Myth 1: solar power is too expensive to be of much use. In reality, today's bulky and expensive solar panels capture only 10% or so of the sun's energy, but rapid innovation in the US means that the next generation of panels will be much thinner, capture far more of the energy in the sun's light and cost a fraction of what they do today. Myth 2: wind power is too unreliable. Actually, during some periods earlier this year the wind provided almost 40% of Spanish power. Parts of northern Germany generate more electricity from wind than they actually need. Northern Scotland, blessed with some of the best wind speeds in Europe, could easily generate 10% or even 15% of the UK's electricity needs at a cost that would comfortably match today's fossil fuel prices. Myth 3: marine energy is a dead-end. This year we have seen the installation of the first tidal turbine to be successfully connected to the UK electricity grid in Strangford Lough, Northern Ireland, and the first group of large-scale wave power generators 5km off the coast of Portugal, constructed by a Scottish company.

Note: The remaining energy myths treated in this article are: Myth 4: nuclear power is cheaper than other low-carbon sources of electricity. Myth 5: electric cars are slow and ugly. Myth 6: biofuels are always destructive to the environment. Myth 7: climate change means we need more organic agriculture. Myth 8: zero carbon homes are the best way of dealing with greenhouse gas emissions from buildings. Myth 9: the most efficient power stations are big. Myth 10: all proposed solutions to climate change need to be hi-tech. For lots more on exciting new energy technology developments from reliable sources, click here.

Legislators taking hard look at oil trading

For a few months this summer, the oil market speculator ... helped push oil prices steadily higher, shattering records that had lasted for decades. As oil topped $145 per barrel, Congress started looking for ways to rein the speculators in. Then oil prices plunged, and interest in the issue fizzled. But that may soon change. "This will remain an issue," said Sen. Byron Dorgan, D-N.D., who introduced oil market legislation this year. "Because when the price of oil has gone from $50 to $147 and back, it's clear to me and everyone else that this has nothing to do with supply and demand. It has to do with speculation." Among possible changes, Congress may try to assert more authority over unregulated oil swaps that don't take place on any formal market. Many factors helped shove prices higher, including the growth of China's economy and the decline of the American dollar. But oil kept rising even as gasoline sales fell in the United States, the world's largest oil consumer. That wouldn't have happened if supply and demand really were driving the market, many analysts say. "The entire move from $70 (per barrel) to $147 was people fleeing the dollar and looking at oil as an asset class," said Amy Myers Jaffe, an energy research fellow at Rice University's Baker Institute. "It was speculators, so when they exited the market, we went right back to $70." Speculators are investors who trade in oil or other commodities strictly as a financial investment. They include hedge funds and investment banks as well as retirement funds.
