  • Solar power plant plans move ahead in California

    After a long drought, large-scale solar power is getting closer to returning to the U.S. desert. The California Public Utilities Commission on Thursday gave the green light to power purchase agreements which two utilities have with solar power project ...


  • Mirrors in Dawn Dusk Orbit for Low-Cost Terrestrial Solar Electric Power in the Evening

    Herein, a constellation of mirror satellites in a dawn dusk polar orbit is desciibed with the mirrors deflecting sunbeams down to terrestrial solar electric power fields producing additional solar energy in the early morning and evening hours. A specific mirror satellite design is described where each satellite is comprised of a lightweight thin aluminized mirror membrane stretched flat by three ...

  • Parabolic Trough or Solar Tower? A technology decision

    Securing cost reductions and carving out routes to grid parity remains as ever the most pressing issue for the CSP industry. At the crux of this pursuit is understanding the associated costs of the CSP technologies themselves, whether it be Parabolic Trough, Solar Tower, Linear Fresnel or Dish Sterling. Delving even deeper, the ability to identify and successfully implement cost reduction ...

  • Charting economic climate

    The economic climate affects our day-to-day lives. Work activities are intricately interconnected with social well-being which in turn effects family harmony and trickles on down to impact personal wherewithal. Still, 'climate' is what it is. There is nothing any of us alone can do about it. At the same time, however, how we think about it tends to shift the reality we experience day to day. ...
