A sea of green

"Algae is the ultimate biological system using sunlight to capture and convert carbon dioxide into fuel... I came up with a notion to trick algae into pumping more [fuel] out." Craig Venter's Synthetic Genomics partners with ExxonMobil in a $600M project to harvest biofuels from genetically engineered algae. "We have modest goals of replacing the whole petrochemical industry." [previously] "Over the next 20 years, synthetic genomics is going to become the standard for making anything. The chemical industry will depend on it. Hopefully, a large part of the energy industry will depend on it. We really need to find an alternative to taking carbon out of the ground, burning it, and putting it into the atmosphere. That is the single biggest contribution I could make."

Ten new wind turbine designs. Curious, grotesque, sculptural, beautiful, utilitarian.

What is the solar potential of your roof

Have you ever thought about putting solar panels on your roof? Would you like to know how much power you can generate and what it would cost. RoofRay is a fun site that will calculate it for you and then let you know how much it would cost and how many years you'd need to recoup your investment. You enter an address into a version of Google Maps, and then draw where you want to put the array on your preferably southern facing roof.

In Lester R.

How Africa's desert sun can bring Europe power

How Africa's desert sun can bring Europe power. A £5bn solar power demonstration project called Desertec is being developed by Trans-Mediterranean Renewable Energy Cooperation (TREC) that would send solar energy northward from African deserts. The goal is in 30 years to provide a significant fraction of Europe's electricity needs.

The Shipyard

Founded in Berkeley by artist Jim Mason, The Shipyard, a collaborative industrial arts space constructed from recycled shipping containers, has hosted numerous large-scale projects and events including a Survival Research Labs show, Power Tool Drag Races, gassification experiments and workshops, and various large-scale Burning Man projects such as 2005's Clockworks. Short documentary here (quicktime). However, relations with the city of Berkeley have been consistently tense. Recently, the city shut off the Shipyard's power, to which the Shipyard responded by going off grid. On May 8, Berkeley issued 3-day vacate and abate notice, with which the Shipyard is attempting to comply (auto-playing video).

Got power?

An alternative means towards alternative energy? Duke Energy in NC is offering its customers an opportunity to vote for alternative energy sources with their wallets starting today. While you are not really buying the Green Power directly, you are in effect subsidizing it. Is this a creative way to Go Green, or just another feel good gesture?
