OriginOil Unveils Layered-Growth SystemMay 25, 2010 - renewableenergyworld.com
OriginOil Inc. this week unveiled a new direct-solar growth design that the company said uses growth layers to harness solar energy more effectively than existing pond systems, while reducing the real estate required.
The resulting system may be 10 to 20 times more efficient than single-layer systems.
"Algae ponds and channels are great for tapping the sun's energy, but they require vast amounts of land," said Riggs Eckelberry, OriginOil's CEO. "We simply stacked the algae layers to multiply the benefits of 'free' solar energy. The result is an ideal mix of sustainable growth and industrial-grade concentration."
The new design uses an array of lenses to direct solar radiation from the top through a system of algae channels. Algae culture is pumped continuously to the top of the array and then trickles down through the layers, ensuring equal exposure. Tapping units at the end of the stack capture valuable gases.
