Society is dependent on transport systems, not only to meet its daily needs with short journeys but also to meet their arising needs with longer distances. The ability to connect remote regions and the trip duration makes the aircraft a mode of transport for distant travel. However, it impacts greenhouse gas production. The survey for new ways to reduce greenhouse gas emissions emerges from the contribution of energy harvesting systems. Energy harvesting technology has been presenting prosperous solutions and applications in road pavements. Due to the similarity between road pavements, this paper addresses state-of-the-art technologies for airport pavements and road pavements, aiming to analyze which ones can be developed for application in airport pavements. An analysis is presented not only for the density, efficiency, and energy generation, but also for each energy harvesting technology’s implementation and technology readiness level. The photovoltaic technology, to be incorporated into airport pavements, will allow sustainable energy generation dependent on the airport location. The hydraulic/pneumatic technology, to be incorporated into the airport pavements, will generate electrical energy based on aircraft movement.

Supersonic Flutter

The harvesting of electrical energy generated from the flutter phenomenon of a plate wing is studied using the quasi-steady aerodynamic theory and the finite element method. The example of supersonic flutter structure comes from sounding rockets’ wings. Electrical energy is harvested from supersonic flutter by using piezoelectric patches and switching devices. In order to evaluate the harvesting performance, we simulate flutter dynamics of the plate wing to which piezoelectric patches are attached. We demonstrate that our harvesting system can generate much more electrical energy from wing flutter than conventional harvesting systems can. This flutter utilization changes our perception to a useful one in various fruitful applications from a destructive phenomenon.

Physical Comfort

The current building is expected to provide physical comfort, such as room comfort, temperature, sound and lighting. Some equipment is needed that requires electrical energy to provide physical comfort. Like a room cooling device to provide thermal comfort, a room lamp to provide lighting comfort. The ITERA building built by the City Government of Bandar Lampung has high solar energy potential. While the electricity source still uses diesel fuel. The potential for solar energy radiation is used to become electrical energy by using glass windows as the foundation for installing solar energy harvesting systems using solar PV.

Abstract Wireless Sensor Networks (WSNs) have existed for many years and had assimilated many interesting innovations. Advances in electronics, radio transceivers, processes of IC manufacturing and development of algorithms for operation of such networks now enable creating energy-efficient devices that provide practical levels of performance and a sufficient number of features. Environmental monitoring is one of the areas in which WSNs can be successfully used. At the same time this is a field where devices must either bring their own power reservoir, such as a battery, or scavenge energy locally from some natural phenomena. Improving the efficiency of energy harvesting methods reduces complexity of WSN structures. This survey is based on practical examples from the real world and provides an overview of state-of-the-art methods and techniques that are used to create energyefficient WSNs with energy harvesting.

Demand for green energy is in tremendous growth in the last decade. The continuous growth in production of portable RF systems increase the consumption of batteries and electrical energy. Batteries and conventional electrical energy increase the environmental pollution. Compact wideband efficient antennas are crucial for energy harvesting commercial portable sensors and systems. Small antennas have low efficiency. The efficiency of 5G, IoT communication and energy harvesting systems may be improved by using wideband efficient antennas. Ultra-wideband portable harvesting systems are presented in this chapter. This chapter presents new Ultra-Wideband energy harvesting system and antennas in frequencies ranging from 0.15GHz to 18GHz. Three wideband antennas cover the frequency range from 0.15GHz to 18GHz. A wideband metamaterial antenna with metallic strips covers the frequency range from 0.15GHz to 0.42GHz. The antenna bandwidth is around 75% for VSWR better than 2.3:1. A wideband slot antenna covers the frequency range from 0.4GHz to 6.4GHz. A wideband fractal notch antenna covers the frequency range from 6GHz to 18GHz. Printed passive and active notch and slot antennas are compact, low cost and have low volume. The active antennas may be employed in energy harvesting portable systems. The antennas and the harvesting system components may be assembled on the same, printed board. The antennas bandwidth is from 75–200% for VSWR better than 3:1. The antennas gain is around 3 dBi with efficiency higher than 90%. The antennas electrical parameters were computed by using 3D electromagnetic software in free space and in vicinity of the human body. There is a good agreement between computed and measured results.

There are several small energy sources that can be exploited to provide useful energy: small temperature differences, mechanical vibrations, flow variations, latent exhausts are just some examples. The recovery of such common and small energy sources, usually wasted, for example with the conversion into useful amounts of electrical energy, is called energy harvesting. Energy harvesting allows low-power embedded devices to be powered from naturally-occurring or unwanted environmental energy (e.g. pressure or temperature difference). The main aim in the last years of researches in such field, was the increasing of the efficiency of such components, with a higher power output and a smaller size. At present, a wide range of systems incorporating energy harvesters are now available commercially, all of them specific to certain types of energy source. Energy harvesting from dissipation processes such as fluid lamination is a challenge for many different applications. In addition, control valves to dissipate overpressures are common usage of many plants and systems. This paper surveys the market opportunities of such harvesting systems, considering the trade-offs affecting their efficiency, their applicability, and ease of deployment. Particular attention will be devoted to small energy harvesters than can exploit small expansions, such as from lamination valves or to systems that can feed mini sensors from small pressure drops, promising compactness, efficiency and cost effectiveness.

Hydrogen, reacting with oxygen, is a very energetic, non-polluting fuel. Can it be used as a fuel for gas turbines? Two successful and significant examples of its use are reviewed. Surplus renewable electrical energy from solar and wind could be used for electrolysis of water to produce hydrogen to power gas turbine power plants. Serving as a means of energy storage, the hydrogen could be kept in caverns. It could also be added directly to natural gas pipeline systems serving gas turbine power plants, thus reducing greenhouse gas production.
