A U.S. brewery has found the ultimate way to hareness the energy of the Sun God - by brewing beer.

Stone Brewing annouced the upcoming installation of a 360.7kW AC (404.6 kW DC) Photovoltaic Solar System on the roof of its new brewing facility in the Escondido Research & Technology Center (ERTC). The $3.2 million dollar system will supply the brewery with a significant portion of its total electrical power—up to an anticipated 54%. According to Stone Brewing’s general contractor Hamann Construction, the system could be installed and generating electricity by February 2008, and would number in the top 12% of solar systems in the State.

Bio diesel passes US standards

Solazyme, the San Francisco based bio tech compan, has produced the first Algal-Based renewable Bio Diesel to pass American Society for Testing and Materials specifications.

Solazyme announced today that SoladieselRDTM , a microalgae-derived renewable diesel, has passed American Society for Testing and Materials (ASTM) D-975 specifications. The company claims that SoladieselRDTM is the first algal-based renewable bio diesel to meet these standards.

In a 100% blend, SoladieselRDTM has been road tested in a factory standard 2005 Jeep Liberty diesel. The fuel’s chemical composition is identical to that of standard petroleum based diesel, and SoladieselRDTM is fully compatible with the existing transportation fuel infrastructure. Having fewer particulate emissions, SoladieselRDTM also has a more desirable environmental footprint than standard petro-diesel. In addition, it meets the new ASTM ultra low sulfur diesel (ULSD) standards.

“This now marks the production of our second fuel that meets current U.S. fuel specifications and is an important validation of our proprietary process using microalgae to produce renewable fuels,” said Jonathan Wolfson, chief executive officer of Solazyme. “Solazyme’s leadership in the green fuels space will continue to grow as we now execute on our strategy for commercial launch.”

The only advanced biofuels company producing at scale, Solazyme implements a unique microbial fermentation process that allows algae to produce oil in massive vessels quickly, efficiently and without sunlight. The process can utilize many forms of non-food feedstocks, including waste glycerol and many cellulosic materials including wood chips, corn stover and switchgrass. The resulting oils can be leveraged across a wide variety of industries and applications, including fuels, edible oils and chemicals and are completely biodegradable, nontoxic and safe.

New Age for Dirigibles

Imagine gliding in a floating hotel over the Serengeti, gazing down at herds of zebra or elephants; or floating over Paris as the sun sets and lights blink on across the city as you pass the Eiffel Tower.

Such flights of fancy may one day be possible, if the dream of Jean-Marie Massaud, a French architect, comes true.

As the cost of fuel soars and the pressure mounts to reduce carbon dioxide emissions, several schemes for a new generation of airship are being considered by governments and private companies. “It’s a romantic project,” said Mr. Massaud, 45, sitting amid furniture designs in his Paris studio, “but then look at Jules Verne.”

It has been more than 70 years since the giant Hindenburg zeppelin exploded in a spectacular fireball over Lakehurst, N.J., killing 36 crew members and passengers, abruptly ending an earlier age of airships. But because of new materials and sophisticated means of propulsion, a diverse cast of entrepreneurs is taking another look at the behemoths of the air.

Mr. Massaud, a designer of hotels in California and a stadium in Mexico, has not ironed out the technical details, nor has he found financiers or corporate backers for his project — to create a 690-foot zeppelin shaped like a whale, with a luxury hotel attached, that he has named Manned Cloud.

But not all projects are as fanciful as Mr. Massaud’s. For example, a French technology start-up, Aerospace Adour Technologies, is working with the French post office to study the feasibility of transporting parcels by dirigible. Also in France, Theolia, a company specializing in renewable energy, is financing a dirigible, and plans a test flight across the Atlantic.

In Germany, Deutsche Zeppelin-Reederei, the successor to the operator of the Hindenburg, has had success with a new generation of airship it uses to transport sightseers and scientific payloads.

The trend is not entirely new. Zeppelin-Reederei carried 12,000 passengers on sightseeing tours over southern Germany last year. Aerophile, a French company that revived tethered balloons, which compete with dirigibles as carriers of passengers, advertising and scientific instruments, was founded by two young French engineers in 1993.

The aircraft industry is not exactly bracing for a dogfight. Mr. Massaud says that Emirates and Air France have expressed interest in Manned Cloud. But with top speeds of around 100 miles an hour and a maximum capacity of several dozen passengers, dirigibles are expected by most aviation experts to remain niche vessels for ferrying tourists, advertising and occasional scientific payloads.

“A dirigible is something magical,” said Jérôme Giacomoni, who was 25 when he founded Aerophile with a friend. “But most of the ideas are crazy.”

Dirigibles, he said, “are very sensitive to storms. Their size requires large landing spaces; economically they’re not feasible.”

Not yet, say dreamers like Mr. Massaud. But gasoline prices are pushing airlines to reduce the number of flights and retire older, less fuel-efficient aircraft. Aircraft manufacturers like Boeing and Airbus have responded by promising planes that use less fuel and produce less carbon dioxide.

Such concerns pushed Mr. Massaud to start thinking about dirigibles. Five years ago he worked on a design for a resort community in Palm Desert, Calif., but the result was so radical, involving tents rather than fixed buildings, that its developers balked. “They said to me, ‘You French, you’re all Communists!’ ” he said.

So Mr. Massaud conceived of Manned Cloud, a helium-filled dirigible shaped like a whale, with a cruising speed of 80 miles an hour and a cabin to accommodate 50 overnight guests and a crew of 25. “The large whales made a choice in evolution to live in harmony with their environment,” he said. “They are symbols of life in harmony with nature.”

Mr. Massaud submitted his design to the French aerospace agency, whose experts suggested he reduce the number of passengers to 15 and made other recommendations, but withheld judgment on his design’s feasibility.

“There are niches where dirigibles might still serve,” said Philippe Guicheteau, special adviser for military aeronautical systems at the agency, which goes by the French acronym Onera.
