Energy recovery time

As of this writing, it has not been possible to use the seismic data which defines the volume of the reservoir to also determine the joint stmcture. Extended flow testing is the most direct measure of the efficiency and sustainabiUty of energy recovery from the reservoir. The use of chemical tracers in the circulating fluid can also provide valuable supporting data with regard to the multiplicity of flow paths and the transit time of fluid within the reservoir (37). 

There is an important feedback factor which cannot be properly evaluated at this time. It concerns future municipal investment in a specific waste control system. This could result in legislation controlling the input of important potential waste materials to the municipality. For example large capital investment in a heat/energy recovery system based on incineration might induce legislative restrictions on low calorific materials like metals and glass. 

Notice the intermediate in the reaction of citrate synthase (fig. 13.7). Do you think at some time in the future evolution will produce a variety of citrate synthase that recovers the energy in the thioester, analogous to the production of GTP (ATP) by succinate thiokinase (page 291) Would this energy recovery have any effect on the thermodynamics of the tricarboxylic acid cycle ... 

We note that neither the OPCL nor the adaptive control algorithms were devised to optimize the energy of the control, but rather the recovery time. It is clear that these methods are insensitive to the initial conditions at the CA. The shapes of the control functions are, to a large extent, also prescribed by the algorithms and are not optimized. In this sense the high energy of the control functions is not a surprise the results presented serve the purpose of illustrating the main point the sensitivity of the optimal control to the shape of the control function and to the initial conditions, discussed above. 

Limited. The operating parameters (residence time, temperature, etc.) can be varied in a narrow range. Generally used to produce fuel gas for energy recovery... 

Viscoelastic foams show a stress-relaxation phenomenon, i.e., delay of complete deformation recovery after compression. These foams usually take 2 to 30 seconds to recover after 50% compression. In contrast, HR foams and conventional flexible polyurethane foams show very short deformation-recovery times, e.g., less than 1 second. This means that these foams have low viscoelasticity or small energy absorption.
