The first of three Siemens' H-Class gas turbines has been successfully started at Florida Power & Light Company's (FPL) Cape Canaveral Next Generation Clean Energy Center in Port St. John, Fla., USA, near NASA's Kennedy Space Center. This successful start was enabled by the Siemens full-power output testing program designed to put the turbine through many operating regimes.
First of six Siemens H-Class gas turbines undergoes startup in Florida
FPL, a subsidiary of U.S.-based NextEra Energy, Inc., serves the third most customers of any American electric utility, with approximately 4.6 million accounts, and is known for its reliable service, clean emissions profile and comparatively low rates. When FPL's state-of-the-art Cape Canaveral Clean Energy Center enters operation in 2013, it will use Siemens' highly efficient and flexible gas turbines to generate power with 33 percent less fuel per megawatt-hour than the site's previous plant. Because of this fuel efficiency, FPL expects that the new plant will more than pay for itself with fuel savings for customers estimated at more than $1 billion over its 30-year operational life.
Three more units of the model SGT6-8000H gas turbine will also be installed at a similar new plant under construction in Riviera Beach, Fla., USA. That project, FPL's Riviera Beach Next Generation Clean Energy Center, is scheduled to enter operation in 2014.
The SGT6-8000H is the scaled 60-Hz version of Siemens' successful SGT5-8000H gas turbine, which made power plant history in May 2011. Installed in a combined-cycle power plant configuration at Irsching Power Station in Bavaria, Germany, the SGT5-8000H achieved world-record efficiency of 60.75 percent. The SGT6-8000H is designed to 274 MW output of electric power, and is likewise capable of reaching efficiencies topping 60 percent in combined-cycle operation, which FPL's Cape Canaveral and Riviera Beach plants will employ.
"Clean and efficient power generation is one of the most important milestones on the road to a new, more sustainable age of electricity. The H-Class is a landmark in engineering and energy efficiency. Since its initial startup at the Irsching Power Station in Germany, this new machine has run extremely successfully for more than 18,000 operating hours. The 60-Hz version will contribute significantly to clean power generation in Florida and serve as yet another example of FPL's leadership among U.S. utilities," said Roland Fischer, CEO of the Fossil Power Generation Division of Siemens Energy.
"By significantly reducing the amount of fuel we need to burn to generate electricity, Siemens' fuel-efficient turbine technology will help us continue to provide our customers with reliable, clean power at the lowest typical electric bills in the state," said Mark Lemasney, plant general manager of FPL's Cape Canaveral Next Generation Clean Energy Center. "The successful test-fire is an exciting milestone for this important investment, and we look forward to continuing to work with Siemens as we prepare the plant to enter operation next year."

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
