28 Green Power Generations and Environmental Monitoring Systems …

production of electricity was 2.7 W at 12.2 Hz with a temperature difference of 674 K.
The power generation efficiency, however, is very low.
Since it turns out that a thermal loss becomes large when the temperature of a
heating head becomes high, to improve power generation efficiency, it is necessary
to generate at low temperatures.
Substances evaporated below 40 °C that are used in binary power generation
(geothermal power generation: e.g., power generation using Bentan: boiling point
36 °C., Ammonia: lower temperature) enables power generation at a considerably
lower temperature. When such a device is attached to the front of a parked car in
summer, the heat of sunlight is taken away to generate electricity that can keep the
car interior cool.
Moreover, by using transparent DEs, there is no more discomfort and power can
be generated by using the temperature difference between the human body/animal
and the external temperature, enabling the recovery of some of the electricity used.
Within the lab, we are developing flexible DE generators. It is becoming possible to
make a flexible generator attached to clothes or tree leaves.
28.3.2 Efficient Consumption of Energy Within Smart Cities
Smart grids are not only efficient for the operation of power plants and power grids,
but also for the installation of power generation facilities in places such as homes,
offices and factories where power can meet the needs of those users. This means that
a decentralized DE energy supply system not relying solely on conventional large
power plants has to be built. The point is that it is important to use the device that
stores power in the middle (EV battery, battery for cogeneration or electric double
layer capacitor using DE) as efficiently as possible.
Figure 28.12 shows sites where power generation using DEs is possible and
conceptual rendering of the generation systems. Those are divided into two types:
(1) DE power generation systems in which the obtained electric power is consumed
locally and (2) ultra large DE generation systems installed in the ocean.
(1) DE power generation system in which obitained electric power cosumed in
locally:
(a) Wind Power Generators on tops of buildings (Chiba et al. 2007b; Chiba
and Waki 2011)
(b) Water Mill Generators (Chiba 2007a)
(c) Waste energy Generators (Chiba and Waki 2011)
(d) Drain Generators (Chiba and Waki 2011)
(e) Wind Power Generators for Personal Houses (Chiba and Waki 2011)
