Methods and apparatus are provided for more efficiently computing error checking codes such as cyclic redundancy checks. The control allows a user to place the three-way valve into one of a first ON state in which the first outlet port is in fluid communication with the inlet port, a second ON state in which the second outlet port is in fluid communication with the inlet port, and an OFF state in which substantially no fluid is allowed to exit the inlet port. Deionized water is generally to be used in making up the emulsion. Water in the first heat exchange device may be converted to steam to generate electric power.
