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.

    CATCHING MORE WIND

    Wind turbine system recycles 'spillage' to improve energy efficiency

    Scott Shrage, September 17, 2015 (PhysOrg)

    “...[A prototype system showed wind turbine efficiency can be improved more than 18 times the estimated monthly energy use of the average American household by capturing and storing surplus energy for later use as electricity [according to a new paper by University of Nebraska-Lincoln doctoral candidate Jie Cheng]…The system would also marginally cut total energy costs while significantly reducing fluctuations in power generation…Physicists have shown that only 59.3 percent of the kinetic energy from wind can be captured by a rotor, with modern wind turbines designed to approach this limit…[but when wind exceeds their] speed threshold, turbines adjust their blade angles to maintain a constant energy output and prevent potential mechanical damage. The resulting ‘mechanical spillage’ means that turbines fall well short of utilizing their full capacity…[Cheng's system directs] the spillage to an air compression tank, where the excess energy remains until wind speeds dip enough to pull the turbine back beneath its optimal capacity. At that point, the tank kicks in to regenerate the electricity…” click here for more
