Algae: 'The ultimate in renewable energy'
"Algae is the ultimate in renewable energy," Glen Kertz, president and CEO of Valcent Products, told CNN while conducting a tour of his algae greenhouse on the outskirts of El Paso.
Kertz, a plant physiologist and entrepreneur, holds about 20 patents. And he is psyched about the potential algae holds, both as an energy source and as a way to deal with global warming.
"We are a giant solar collecting system. We get the bulk of our energy from the sunshine," said Kertz.Algae are among the fastest growing plants in the world, and about 50 percent of their weight is oil. That lipid oil can be used to make biodiesel for cars, trucks, and airplanes.
Most people know algae as "pond scum." And until recently, most energy research and development projects used ponds to grow it.
