Would it make sense to place a turbine (similar to those used in dams) at the bottom of a grain elevator? I live in Alberta Canada and every year about 16 billions pounds of grain is harvested. A large portion of this grain is stored in very tall grain elevators. The grain then “drains” into train cars to be transported. This seems as though a lot of potential energy is wasted as grain is draining into train cars. So, would it work to put a turbine that spins when the grain drains into the train cars? As I see it even if the energy produced was used to help power the grain elevator it would help to reduce the environmental footprint and cost associated with running a grain elevator.

I should add that wheat is the most common crop farmed in Alberta.

Is there any reason that wheat would not flow through a turbine?

Any insight will be immensely appreciated!
