Gleanings from the web and the world, condensed for convenience, illustrated for enlightenment, arranged for impact...

While the OFFICE of President remains in highest regard at NewEnergyNews, this administration's position on climate change makes it impossible to regard THIS president with respect. Below is the NewEnergyNews theme song until 2020.

The challenge now: To make every day Earth Day.

    WIND READY TO GO GIGANTIC

    Sandia National Laboratories: A 50-MW turbine requires a rotor blade more than 650 feet (200 meters) long, two and a half times longer than existing wind blades

    January 28, 2016 (Network World)

    “US researchers at Sandia National Laboratories say they are working on a design for gigantic wind turbine blades that are longer than two football fields which could support 50-megawatt-- more than six times the power output of the largest current turbines --offshore wind farms in the future…[M]ost US wind turbines produce power in the 1- to 2-MW range, with blades about 165 feet (50 meters) long, while the largest commercially available turbine is rated at 8 MW with blades 262 feet (80 meters) long. A 50-MW turbine requires a rotor blade more than 650 feet (200 meters) long, two and a half times longer than any existing wind blade…Such exascale blades could be cost-effectively manufactured [and transported] in segments…The exascale turbines – called Segmented Ultralight Morphing Rotors (SUMR)-- would be positioned downwind, unlike conventional turbines that are configured with the rotor blades upwind of the tower…” click here for more
