Abstract: A new approach for desalination and purification of sea water using refrigeration units is suggested which seems promising to provide high quantities of drinkable water with reasonable cost. The apparatus uses compression refrigeration system to provide heat at the condenser to partially evaporate the intake sea water and uses evaporator at the other side to condense the produced water vapor back to clean drinkable water. A heat recovery heat exchanger captures the heat left in the returning sea water and delivers it to the fresh intake sea water to improve the efficiency and performance. The system can be designed using different refrigerants with some providing higher efficiencies and coefficients of performance. A typical desalination system using this approach shows in theory a production of about 3.6 trillion gallons of potable/drinkable water per year with only about 100 MW electric power installed. Equivalent electrical energy (kWh/m3) consumed by different methods has been reported about 13.5-25.

Abstract: Methods and devices for interacting with information using a computing device. A plurality of nodes in a database may be created and stored on a non-transitory computer readable medium and accessible by a processor. Each node may have at least one data element and be linked to at least one other of the plurality of nodes such that the link reflects a relationship between the data elements referenced by the linked nodes. A plurality of information areas may be displayed, each displaying information stored in one of the data elements and positioned relative to the plurality of information areas based on the relationship. The plurality of information areas may be positioned such that a final portion of information displayed in a first information area in a sequence is aligned with an initial portion of information displayed in a subsequent information area in the sequence.
