Challenge
How do you keep 760 parabolic troughs holding 182,000 curved mirrors precisely tracking and focusing the sun's energy within 0.1 degree, even in 40 mile per hour winds?

Solution
Let's create a more powerful, rugged rotary motion control system. A system that can withstand high winds, not to mention backlash within the actuator — thanks to a "clutching" action inherent in hydraulic systems with pressure-relief valves. A system, according to Woodie Frances, Parker product manager for hydraulic rotary actuators, that can "help deliver maintenance-free operation for more 20 years."

So, what are you waiting for? Let's get moving. After all, together, we can design the kind of reliable, green technology systems solutions that won't just move your business forward--they'll move the world forward.

Just the Facts
Acciona Nevada Solar One™

• Located just outside Las Vegas in Boulder City, Nevada
• World's third-largest solar-energy field
• 64-MW solar thermal power plant
• 300 acres
• Generates approximately 129 million kW-hr of electricity annually
• Enough to power 14,000 homes
• Renewable energy alternative with no fossil-fuel emissions
• Largest solar plant of its kind built in the U.S.A. in more than 16 years

And How About Some Fun Facts?

• The amount of solar energy intercepted by the Earth every minute is greater than the amount of energy the world uses in fossil fuels each year (Renewable Energy. February 20, 2009)
• Tropical oceans absorb 560 trillion gigajoules (GJ) of solar energy each year, equivalent to 1,600 times the world's annual energy use (Renewable Energy. February 20, 2009 )
  
• Over the course of a year, Europe consumes only .6% of the unused solar energy falling in the desert. Lubbadeh, Jens. "Can Desert Solar Supply Europe's Energy?" BusinessWeek. May 1, 2008. February 13, 2009 )
