TL;DR: In this article , a case study of fuel cells, particularly solid oxide fuel cells for their fuel-to-energy conversion ratio and close to no emissions, is presented to find a powerful and efficient propulsion system that runs on renewable resources, which can drastically reduce the price per ticket and make air travel much more economical and environmentally clean.
Abstract: According to the International Air Transport Association (IATA), the industry has improved its record of fuel efficiency: Fuel burned per passenger per kilometer has dropped by half since 1990. This case study aims to find a powerful and efficient propulsion system that runs on renewable resources. We’ll dive deep into the study of fuel cells, particularly solid oxide fuel cells for their fuel-to-energy conversion ratio and close to no emissions. This study will help us understand what fuel cell design, where it’ll be installed, materials of the cathode, and anode. Different materials for electrolytes will be compared to analyze each of their impact on a flight’s performance which can drastically reduce the price per ticket and make air travel much more economical and environmentally clean. What storage method will be preferred for space efficiency, more capacity to reduce travel time by fueling just once, and to keep hydrogen safe from igniting itself. Fuel cells are still a work in progress due to their lack of instant power, so engineers combined them with a gas turbine creating a hybrid setup that achieves an amazing efficiency. Airlines such as Airbus, Eviation, and Zunum Aero are working on all-electric aircraft (AEA) where their planes are powered by hydrogen fuel cells.

TL;DR: In this paper , an alternative green power generation system which uses the weight and momentum of passing vehicles to produce electricity to save "waste" power is presented. But the main objective of this article is to analyze the alternative green energy generation system, which uses struts to restore the bumps to their original location.
Abstract: AbstractDue to the rapidly increasing emissions of fossil fuels and the limited amount of power currently available, renewable power generation is an essential need of time. The main objective of this article is to analyze the alternative green power generation system which uses the weight and momentum of passing vehicles to produce electricity to save “waste” power. This design uses struts to restore the bumps to their original location, A slider-crank mechanism converts reciprocatory action into rotatory action and a gear which transmits power. Speed breakers are a versatile and cost-effective alternative that may be installed under the railroad with minimum modifications.KeywordsPower generationSpeed generationElectricityConnecting rodStrutBumpsDisc crankKinetic powerMechanical powerVehicle

TL;DR: The potential for extensive application of cast composites is very large in India, especially in the areas of transportation, energy and electromechanical machinery; the extensive use of composites can lead to large savings in materials and energy, and in several instances, reduce environmental pollution as mentioned in this paper.
Abstract: This paper reviews the world wide upsurge in metal matrix composite research and development activities with particular emphasis on cast metal-matrix particulate composites. Extensive applications of cast aluminium alloy MMCs in day-to-day use in transportation as well as durable good industries are expected to advance rapidly in the next decade. The potential for extensive application of cast composites is very large in India, especially in the areas of transportation, energy and electromechanical machinery; the extensive use of composites can lead to large savings in materials and energy, and in several instances, reduce environmental pollution. It is important that engineering education and short-term courses be organized to bring MMCs to the attention of students and engineering industry leaders. India already has excellent infrastructure for development of composites, and has a long track record of world class research in cast metal matrix particulate composites. It is now necessary to catalyze prototype and regular production of selected composite components, and get them used in different sectors, especially railways, cars, trucks, buses, scooters and other electromechanical machinery. This will require suitable policies backed up by funding to bring together the first rate talent in cast composites which already exists in India, to form viable development groups followed by setting up of production plants involving the process engineering capability already available within the country. On the longer term, cast composites should be developed for use in energy generation equipment, electronic packaging aerospace systems, and smart structures.

TL;DR: In this article, the authors summarized the development of the design concept of high damping composite materials and the investigation of their fabrication and properties, including mechanical and damping properties, and suggested a new design concept where the hard ceramic additives exhibit high vibration damping capacity at room temperature owing to the stress-induced reorientation of high density point defects in the ceramic phases and the high stiffness of the composite comes mainly from the ceramic phase.
Abstract: Nowadays it is commonly considered that high damping materials which have both the good mechanical properties as structural materials and the high damping capacity for vibration damping are the most direct vibration damping solution. In metals and alloys however, exhibiting simultaneously high damping capacity and good mechanical properties has been noted to be normally incompatible because the microscopic mechanisms responsible for internal friction (namely damping capacity) are dependent upon the parameters that control mechanical strength. To achieve a compromise, one of the most important methods is to develop two-phase composites, in which each phase plays a specific role: damping or mechanical strength. In this review, we have summarized the development of the design concept of high damping composite materials and the investigation of their fabrication and properties, including mechanical and damping properties, and suggested a new design concept of high damping composite materials where the hard ceramic additives exhibit high damping capacity at room temperature owing to the stress-induced reorientation of high density point defects in the ceramic phases and the high damping capacity of the composite comes mainly from the ceramic phases.
