This video offers a fresh look at bio fuel production.  In the past, significant manual labor and fuel heavy fossil fueled mechanical labor was required to produce a useable quantity of bio fuel.  Also, many are against the idea of using fuel for food, claiming it has globally driven the price of food up.  It seems as though this is a solution to mass production of renewable bio diesel.   Here  the sun is the main energy used to produce this raw fuel.  

Things to Think About:  This reduces the required fuel using machinery to create it, but is the byproduct of burning this fuel ecological?  Does this process really have the potential to supplement fuel requirements for the world? Is there a better Bio fuel?
