Jet plane to fly on algae-based fuel by 2010? Europe’s algae bloom aims for feasible alternative to fossil fuel
(quote)
"It's exciting because it's achievable," says Peter van den Dorpel, as he looks over the big plastic tubes full of various shades of green algae. His company has designed, produced and marketed the crop in its bid to be the first to provide the aviation industry with a feasible alternative to fossil fuel. In an enormous greenhouse near Roosendaal in the south of The Netherlands, most of the greenhouse is growing tomatoes with impressive efficiency, with one corner dedicated to the cultivation of algae - in a similarly efficient way, according to Mr van den Dorpel. "It's actually like growing tomatoes; the algae need similar things," he says.
This crop uses the warmth, light and a steady feed of carbon dioxide and nutrients to reproduce faster than any other plant on earth. The amount of algae in these tubes can double daily. And that is both the attraction and the problem with algae as a commercial crop. What Algae-Link's system claims to crack, possibly for the first time, is the problem of clogging. A patented internal cleaning system keeps the set-up harvesting twenty-four hours a day.
Royal giggles and Google Doodle - Queen Elizabeth II visits Google's UK headquarters, view laughing baby video
(quote)
LONDON (AP) - She sent her first e-mail in 1976. She has her own Web site. And on Thursday, Queen Elizabeth II uploaded video to YouTube during a visit to Google's British headquarters. The company celebrated the queen's visit by creating a special version of its google.co.uk home page, which featured a silhouette of her head as the second "G" and a regal crown atop the "E" in their logo.
The queen, 82, herself has a presence on YouTube - she launched the Royal Channel in December. There are 54 videos on the channel, which range from the Queen's 1957 Christmas message to a day in the life of Prince Charles. On Thursday, she uploaded archive footage to the channel of a 1969 reception at Buckingham Palace for British Olympians. The monarch has reigned since 1952. According to the Buckingham Palace Web site, the queen sent her first e-mail from a computer on an army base, well before the widespread use of the Internet.
At top of Earth, Arctic ice shrunk by 25%, left islandlike ice cap surrounded by open water, 181 Alaskan villages face erosion
(quote)
This summer, for the first time, both the fabled Northwest Passage through the upper reaches of North America and the Northern Sea Route above Russia opened up, apart from drifting ice. Overall, the expanse of Arctic sea ice was the second smallest in the 30 years of monitoring (summer 2007 was the smallest), and that left an islandlike polar ice cap surrounded by open water. In just the past five years, summer ice has shrunk by more than 25 percent, and so has its average thickness. One consequence of this change is that much of the sun's heat formerly reflected back out to space by the ice sheets is now being absorbed, entrenching the warming process. The acceleration of the ice melt is outstripping earlier predictions of a basically ice-free Arctic summer by mid- or late century. NASA climate scientist H. Jay Zwally now anticipates that most of the Arctic will lose summer ice in only five to 10 years. "We appear to be going through a tipping point," he says.
Senseless overfishing - world's marine fisheries losing $50 billion each year
(quote)
The world's fishing fleets are losing billions of dollars each year through depleted stocks and poor management, according to a UN report. The World Bank and the UN Food and Agriculture Organization (FAO) calculate the losses at $50bn per year. Half the world's fishing fleet could be scrapped with no change in catch.
The report was launched at World Bank headquarters in New York and has been debated here at the World Conservation Congress in Barcelona, Spain. Entitled The Sunken Billions: Economic Justification for Fisheries Reform, it argues that reforming the way fisheries are managed could restore stocks and build profits. "There are two reasons why we are experiencing the huge loss," said Rolf Willman, a senior fisheries planning officer at FAO and one of the report's authors. "One is that global fish stocks are much lower than they could be, so it is harder to catch the amount of fish that we could. "If stocks were higher we could catch the same amount at lower cost. The second reason is that where fishing is poorly regulated, we have much greater harvesting capacity than we need," he told BBC News. read more »
37th Annual Albuquerque International Balloon Fiesta marks 225th anniversary of first manned balloon flight
(quote)
Launched in 1972, the Albuquerque balloon festival draws enthusiasts from all over the world. This year marks the 225th anniversary of hot air balloon flights, with participants representing 42 states and 24 countries. Ballooning has come a long way from the first "flying machines" in France in 1783, which flew a duck, a rooster and a lamb in a smoke-filled balloon. The first human passengers were carried 3,000 feet on November 21, 1783.
Amongst the most popular events is a mass ascension, in which all participants rise into the sky in two waves. During the Dawn Patrol, above, pilots take off before sunrise and appraise wind conditions for the others. The festival lasts nine days. This year it runs from October 4 through October 12. Albuquerque has a long association with ballooning, going back more than a century.
Because of a local wind phenomenon known as the "Albuquerque Box," the area is ideally suited to a balloon festival. In October of every year, the wind follows a predictable pattern, blowing northerly at higher altitudes and southerly at lower altitudes, allowing for a smooth navigation.
Trillion? US national debt clock in Times Square runs out of digits for the first time as debt exceeds $10 trillion
(quote)
The US government's debts have ballooned so badly the National Debt Clock in New York has run out of digits to record the spiraling figure. The digital counter marks the national debt level, but when that passed the $10 trillion point last month, the sign ran out of digits for the first time.
The clock, located in Times Square, shows the amount of money owed by the US government. It was created by the late Manhattan real estate developer Seymour Durst, who put the sign up in 1989 to call attention to what was then a $2.7 trillion debt. The clock's owners say two more zeros will be added, allowing the clock to record a quadrillion dollars of debt.
For the time being, the Times Square counter's electronic dollar sign has been replaced with the extra digit required. For its part, the digital dollar symbol has been supplanted by a cheaper version - perhaps a sign of the times for the American economy.
Some economists believe the $700bn bail-out plan for ailing US financial institutions could send the national debt level to $11 trillion.

Getting worse: half of mammals in decline, 1 in 4 faces extinction; conservation can bring species back
(quote)
BARCELONA, Spain, October 6, 2008 (ENS) - The world's mammals are in the grip of an extinction crisis, with almost one in four at risk of vanishing forever, according to the latest scientific assessment revealed at the International Union for the Conservation of Nature's World Conservation Congress, which opened Sunday in Barcelona.
The new study conducted for the IUCN Red List of Threatened Species for the first time assessed all of the 5,487 mammals on Earth and found that at least 1,141 of them are known to be threatened with extinction. At least 76 mammals have become extinct since the year 1500.
The real situation could be much worse as 836 mammals are listed as Data Deficient. With better information, scientists may classify even more species as being in danger of extinction. "Within our lifetime hundreds of species could be lost as a result of our own actions, a frightening sign of what is happening to the ecosystems where they live," said Julia Marton-Lefèvre, IUCN director general. read more »
