Nanofluidic entropic traps, comprising alternating thin and thick regions, sieve small molecules such as DNA or protein polymers and other molecules. Being self-unfruitful, the present variety requires cross pollination from an apricot, interspecific, or plum that blooms during the mid to late season. The fuel cell system comprises hydrogen fuel, a CO removal system based upon non-Faradaic electrochemical modification of catalyst activity, and a fuel cell stack. Light waves transmitted through the first optical element are selectively transmitted through to or reflected away from the second optical element as a function of wavelength and the separation distance D. The modified roof panels interconnect with the standing seams of the regular roof panels. The analyzing apparatus estimates a gas turbine output by calculating the difference between the estimated steam turbine output and the total output of the turbine plant.
