As observed in day-to-day life, driving on a bumpy road generates vibrational energy in an automobile which is then dissipated by the shock absorbers. But lately, as we progress into the energy-depleting, energy concern awake era, energy efficiency has been a serious concern within the automobile manufacturing industry since the production within the 1900s, researchers realized that the energy dissipated in traditional hydraulic shock absorbers is merit being recovered only within the middle of 1990s. Unlike traditional suspension systems which suppress the vibrations by dissipating the vibration energy into waste heat, the regenerative suspension with energy harvesting shock absorbers can convert the traditionally wasted energy into electricity. Several different techniques followed for the energy harvesting are listed and Two main devices namely rotary and linear electromagnetic generators are analyzed for comfort and handling, body acceleration with and without a generator, and also attempts is made to enunciate the importance of energy conservation techniques in an automobile.

The main aim of the study is to analyze the heat transfer through the clay brick walls of the residential building to find out the dominant mode of heat transfer and incorporate various materials in the wall to reduce heat loss and increase energy efficiency. The transient thermal analysis was performed using the finite element method, and by employing a CFD program focused on heat transfer processes. Later, two models of building wall fragments incorporating the Phase change materials were developed to identify the optimal position of the PCM layer inside the wall and to investigate the role of PCM on the heat transfer rate. Insulation was done with the different types of plywood and finite element simulation was performed to study the change in heat transfer rate. Inserting plywood into the sandwich material with Chinese plywood can reduce the heat transfer content.

Origami, the art of paper folding, is often associated with Japanese culture. Implementing- ing origami into products that make lives easier and that achieve desirable attributes is the main aim of the origami-adapted design process. A thin-walled tube such as a trapezoid origami crash box is one such energy absorption device derived from origami. The surface of this tube is pre-folded to develop an origami pattern that is delicately designed which gives rise to an interesting- ing structure on the surface of a square tube. Geometric, compliance, and comparative analysis are made and the two extreme designs, Trapezoidal and Diamond origami crash boxes are compared for their energy absorption capability.

Carbon nanotubes (CNTs) are one-dimensional tubular structures of carbon that have attracted much attention due to their potential to be used in various fields like energy storage/conversion devices, biosensing devices, drug delivery systems to name a few. Their excellent electrochemical properties like electron mobility, electrical and thermal conductivity, and high surface area make them good material for use in energy storage and conversion materials. The most promising research in the synthesis and applications of CNTs toward energy conversion and storage is highlighted along with limitations faced in mass production.

Added substance Manufacturing (AM) of metallic designs is a warm cycle of layer by layer metal added substance fabricating measure produces parts straightforwardly from 3D CAD models. In this assembling interaction confined electrochemical affidavit joins with the added substance producing technique to make metal parts at room temperature. In this paper, the attainability of Mask-less Electrochemical Additive Manufacturing (ECAM), as a non-warm interaction is considered. Layer by layer testimony has been finished utilizing the electrochemical tips to make nickel microstructures. All the while beat wave qualities and their impacts on affidavit have been considered. Confined electrodeposition (LED) was investigated as an AM the interaction with high power over measure boundaries and yield boundaries. The confinement of electrodeposition is completed by utilizing Ultra microelectrodes (UME) and low tossing power electrolytes. Variety in some cycle boundaries, for example, voltage and terminal hole are found to have a high impact on yield boundaries like thickness. The reproductions can anticipate the yield width of affidavit of analyses with a blunder of 8- 30%, so it can possibly apply as an added substance-producing strategy of complex three-dimensional (3D) parts on the microscale.
