I have read the ASP ( Aquatic Species Program) report about growing Algae and have it processed to be used as a feedstock for Biodiesel . Given that 60% of the body mass of algea is usable oil as compared to only 15% at best from any land grown plant source. My question is what process can be used to EXTRACT the oils from the algae in an efficient manner. I know you can grow Algae in a Brackish water enviroment and I feel that this is a much more reliable and easer way to renew our resource with less impact on the enviroment .. ( no fertilizer- chemicals - added energy to harvest and transport byproducts to industry) With Algea farms you can used Captured CO2 and bubble it into the water stream and have the algae produced . There is a Patented enzyme to help increase production levels. But like everything that works too well it is pushed aside & Further research was stopped in the mid 80's ...go figure... Well I feel the need for Algae production on a large scale is once again in need for more development and to have a assessable & usable product in the Biodiesel Industry.. I wanted to know if any of the members here can help me or direct me to information / equipment that could do this process of pressing out the usable oils from Algae?
