Electroactive Polymer Artificial Muscle has two operating modes: an actuator mode and a generator mode. The actuator mode uses planar deformation of elastomers resulting from the combination of an electrostatic attractive force between electrodes on each side of the film, and a repulsive force within each electrodes, both being generated by a voltage difference applied between the two electrodes. The EPAM generator mode uses the reverse process of the actuator mode, storing the increase in electrostatic energy originating from the deformation of EPAM by an external force. Because the energy for each cycle of deformation does not strongly depend on deformation speed or frequency, a generator working under this phenomenon can harvest energy from a variety of low-frequency natural sources, such as the up and down movement of waves, the gentle movement of rivers, and the movement of human beings and animals. The movement of vehicles and buildings may also be used to generate energy.

<p>The objective of this study is to analyze, from a comprehensive perspective, the economic and environmental effects induced by constructing and operating hydrogen utilization systems presented by METI's roadmap. We focused on a marine transport system for hydrogen produced offshore, hydrogen gas turbine power generation, fuel cell vehicles (FCVs) and hydrogen stations, as well as residential fuel cell systems (RFCs). In this study, using an Input-Output Table for Next Generation Energy Systems (IONGES) with newly established renewable energies and hydrogen-related sectors, we evaluated the induced output, labor and CO₂ from construction and operation of these hydrogen technologies using a uniform approach. Initial investments in facilities based in foreign countries that produce hydrogen, transport it through organic hydride, and supply it to a power station of 1 GW capacity yield an induced production of 2.7 times. This investment can exploit a new opportunity for the utilization of unused renewable energy sources that are abundantly available in foreign countries and reduce significant CO₂ emissions. Additional investments in domestic hydrogen supply systems, FCVs, and RFCs yield an induced production of 2.6 times each. From a comprehensive point of view, the construction of a hydrogen utilization system may result in cost and CO₂ reductions.</p>

The Ionic Semiconductor has been a polymeric semiconductor that contained with some rate earth metal oxides. This semiconductor was an equipment of environment conformity type, since the environmental loading such as power consumption was remarkably small, and it was man and beast harmless. Various solvents and/or atmosphere wre given powerful reduction effect (antioxidative effect) by the convenient and safety method with the semiconductor. In the solvent and/or atmosphere the new active species were generated with the action of this semiconductor. These active species were applied in following field; (1) the battery active reinforcement agents toward various secondary batteries, (2) the power storage system based on the regeneration secondary battery, (3) the cooking oil degradation prevention system toward deep fling manufacturing process, (4) refrigeration and/or thawing system toward keep of freshness of the food and/or selective accelerated ripening, and so on. The authors report the outline of practical application examples of environmental conformity type our products and/or our systems. In addition, it is reported in this lecture that heat exchange efficiency of refrigerant are able to be improved with this semiconductor and relation technologies. The improvement effect of heat exchange efficiency is applied to air-conditioner, refrigerator, and freezing chamber. As the result, large reduction of power consumption is manifested. The obtained practical field data that these reduction effect of power consumption and development of these power consumption reduction systems are reported in detail.
