Need a weekend project around the house? Mark Suppes, web developer by day, has built his own nuclear fusion reactor in a Brooklyn workspace. It kind of makes that project car you’ve got rusting in the garage seem lame by comparison.
America may have taken her first steps in what is sure to be a long, incremental, and sometimes painful shift toward a large-scale clean energy future. Interior Secretary Ken Salazar finally approved the Cape Wind project today, allowing for the construction of 130 turbines at Horseshoe Shoal south of Cape Cod.
The project will be the first major offshore wind project backed by the federal government, and if successful it might not be the last. Salazar said today that Cape Wind is only the first of many wind projects that will dot the Atlantic coast, piping carbon-free electricity back to shore for use in public power grids.
We thought it was cool when a team of Arizona State researchers engineered genetic bombs that blow biofuel-producing cyanobacteria wide open, releasing their sweet fatty acids without intense chemical processing. But now those very same researchers have figured out how to get at those fatty acids in a far less violent manner: by genetically engineering cyanobacteria to secrete their fatty cargos directly through their cell walls.
If you fall into the niche category of eco-conscious boating enthusiast with a desire to circumnavigate the globe on a 100-feet-long catamaran, your long wait is finally over. PlanetSolar – the dream of skipper Roaphael Domjan since 2004 and under construction since 2008 – was unveiled yesterday in Germany.
Scientists have been trying their best to turn algae into the biofuel of the 21st century, and now the U.S. Department of Energy (DOE) wants to put some serious muscle behind all that research. That muscle translates into $78 million of federal funding split between two biofuel consortia, according to an announcement today by U.S. Energy Secretary Steven Chu.
Real leaves are natural energy factories that can split water molecules and create hydrogen ions. Scientists have long tried to copy the molecules involved in creating hydrogen, but a Chinese team took a different tack by creating an artificial structure based on natural leaves as templates. Early tests have shown that the artificial leaves could soak up twice as much light and produce three times as much energy as the real thing, New Scientist reports.
Norwegian oil and gas giant StatoilHydro has inaugurated the world's first floating full-scale offshore wind turbine, paving the way for deep-water wind farms possessing the dual appeal of being out of sight as well as more efficient.
It’s been a few years since the race to make biofuel from algae really heated up. Today more than 50 companies are trying to find a way to affordably squeeze oil from slime, and it seems like the golden age for these tiny autotrophs.
Geobacter, a microbe that generates electricity when placed in mud and wastewater, has been evolved into a far more productive strain, as part of a new University of Massachusetts breakthrough that has researchers thinking of new fuel cell designs.
Science Daily says that Geobacter is about 3-5 nanometers in diameter, which is about 20,000 times finer than a human hair. Geobacter is known for its ability to transfer electrons, which enables it to "extract" energy from biomass.
John B. Carnett, PopSci's staff photographer, is using the latest green technology to build his dream home. This is the first entry in his new blog tracking the build--follow along at popsci.com/green-dream
No, it's not a death ray. The folks at RawSolar are creating what looks like a very affordable solar thermal tracking dish. This is a mini version of the concentrating solar power systems you see commercially in the 25 kilowatt range.
