If this pans out it will be great for the commercial fishermen they take Carp grind it up and use it to replace the fly ash in concrete. It is claimed to be stronger last longer and better for the environment as fly ash has a lot of chemicals in it. May help get some of the Asian carp under some control as it does not matter the size of the Carp as it all gets ground up. Pretty Cool.
