Wind Direction Forward

Wind-Energy - A Revitalized Pursuit was issued by Sandia Laboratories in 1974.  This report discusses challenges of the “energy crunch” and the U.S. goal to maintain high standards of living by developing “promising energy sources that are (1) vast, (2) environmentally acceptable, and (3) economically competitive.”  The authors felt that wind energy was a feasible solution. 

Devising ways to efficiently harness the wind is an ongoing pursuit of scientists around the world.  The wind mills of the past have evolved into high-tech wind turbines, governed by complex computer systems.  These control systems continue to be more and more important as turbines become larger, with more flexible and lighter components.  Advanced controls are necessary to prevent damage and possible malfunction of the turbines.  Facilities for testing new control systems at the National Wind Technology Center are described in the fact sheet Advanced Wind Turbine Controls Reduce Loads

Energy in the Forecast

Wind Power Map

If you can accurately predict the weather, you may be able to predict how much energy can be generated from wind turbines.  That was one objective of the “Great Plains Wind Energy Transmission Development Project,” completed in 2011, to “develop a wind energy forecast system, and demonstrate its efficacy in scheduling power output from wind farms in the Great Plains.”  The forecasting system described in the report was comprised of three elements, a software component using various weather prediction models, a wind energy output model, and a graphical user interface.

Detailed wind resource maps, provided by the Wind Powering America Initiative, are another tool for demonstrating wind resource potential and removing some of the guesswork from wind energy prediction. 

You can read more about the wind, weather, and turbine dynamics in OSTI Collections: Wind Power, and link to many other research reports delving deeper into a range of topics related to wind energy.

Manipulating Matter on a Molecular Scale

Science Communications

Number of quantum dots

Nano=one billionth

Nanotechnology=the manipulation of matter on an atomic and molecular scale 

DOE scientists are working to identify immediate and future ways to utilize this precision science.

Check out Nanoscience and Nanotechnology: From Energy Applications to Advanced Medical Therapies, a video discussion of why nanotechnology is important and how it is useful in various fields, from Dr. Tijana Rajh at Fermilab.

Then watch Nanoscience at Work, Creating Energy from Sunlight, from Paul Alivisatos, Berkeley Labscientist and an authority on artificial nanostructure synthesis.

In one way current nanotechnology resembles the laser technology of the mid-20thcentury—few present uses but extreme promise, if the technical obstacles can be overcome.  Recent patents available through the OSTI DOepatents database provide a sample of both the potential and the challenges of making use of nanotechnology.

Fuel Cell Car

Hydrogen fuel cells are being widely tested as a potential for meeting future transportation needs.

In the technical report, Controlled Hydrogen Fleet and Infrastructure Demonstration and Validation Project, available from the Information Bridge, the U.S. Department of Energy, Mercedes-Benz & Research Development, North America (MBRDNA), Chrysler, Daimler, Mercedes-Benz USA (MBUSA), BP, DTE Energy and Next Energy endeavor to substantiate fuel cell technologies for infrastructure and transportation as well as evaluate technology and commercial market suitability. Tests were performed through the operation and fueling of hydrogen fuel cell vehicles in practical situations, including variations in climate, topography, and driving conditions.

The Team deployed 30 GEN I and 20 GEN II fuel cell vehicles to over 37 customers located in various regions in the United States, which provided real-world lessons for the future of the overall program. This report and many others are available on this topic…find them at the DOE Information Bridge.
