Abstract: An apparatus for drying or conditioning bulk solids, includes a housing including an inlet for receiving the bulk solids, and an outlet for discharging the bulk solids, a plurality of spaced apart heat transfer plates assemblies disposed in the housing between the inlet and the outlet for passage of the bulk solids that flow from the inlet, through spaces between the heat transfer plates, and a sweep gas delivery system for the flow of sweep gas in a first direction across the direction of flow of the bulk solids. The sweep gas delivery system includes at least one valve for reversing the flow of the sweep gas from the first direction to a second direction, opposite to the first direction.

Abstract: The scarcity of fresh water for human consumption and agricultural irrigation is an ongoing problem affecting billions of people. This problem is only getting worse with growing human populations, pollution and global warming. Relying on underground sources of fresh water is not a viable long-term solution. I propose to solve the problem of fresh water scarcity with a new kind of desalination method. This desalination method is comprised of recycled materials thereby reducing the amount of pollution in the world. This desalination method uses no other power sources other than solar energy. The usage of recycled materials and renewable energy sources thereby ensures that this desalination method is a low cost way of transporting seawater and converting it into fresh water.
