Available to synthetic biologists are a wide range of genetic devices. Many of these devices are able to either sense or alter local conditions. The ability to sense a multitude of inputs combined with diverse outputs could enable engineered organisms that interact with their environment in new and complex ways. Currently the complexity of such systems has been limited by our ability to integrate several inputs into a desired output.Simple combinational logic functions, containing 1 to 3 logic gates, have been constructed in Escherichia coli, but more complex logic networks are needed to fully exploit the opportunities presented by these sensors and actuators. Use of genetic logic gates is constrained by the specific molecular interactions that are used to implement each gate. These interactions involve diffusible molecules that can move within the cytoplasm of the cell and therefore are not spatially separated from other gates. To make larger logic blocks, sets of gates that use unique molecular interactions with minimal crosstalk are required.

A conceptual definition and performance evaluation of a 100 megawatt (MW) hybrid  photovoltaic/thermal electric power plant has been carried out. The concept  utilizes the ability of gallium arsenide photovoltaic cells to achieve high  conversion efficiency at high incident fluxes and elevated temperatures. Solar  energy is focused by a field of steerable mirrors (heliostats) onto a tower  mounted receiver whose outer surface is covered with gallium arsenide  (AlGaAs/GaAs) solar cells and whose inner surface is a water boiler. The solar  cells convert a fraction of the incident radiation into electrical energy, and  the remaining energy is extracted at approximately 200 exp 0 C and used to power  a Rankine cycle turbine generator (bottoming cycle). Water is used as the solar  cell array coolant, as the thermodynamic working fluid, and as the thermal energy storage medium. Parametric studies were conducted to select conceptual  design parameters and operational characteristics which imply the lowest  levelized busbar electric energy costs. Parameters varied were collector area, condenser surface area, fan power, ambient temperature, and electric and thermal energy storage capacities. The report describes the concept, outlines the design analysis method, summarizes the parametric study results, and defines the selected plant configuration. The lowest levelized busbar electric energy generation cost, 70 mills/kilowatt-hr., was achieved with a relatively small collector area, 0.8 x 10 exp 6 square meters, and no stored energy. A rough comparison of this combined power plant with a similar photovoltaic plant, operated at lower solar cell temperature and with no bottoming cycle, showed the busbar cost of electricity (BBEC) from the combined system to be approximately 9lower.
