Compressed Air Car
A compressed-air car is a compressed-air vehicle fueled by pressure vessels filled with compressed air. It is propelled by the release and expansion of the air within a motor adapted to compressed air. The car might be powered solely by air, or combined (as in a hybrid electric vehicle) with other fuels such as gasoline, diesel, or an electric plant with regenerative braking. Compressed-air cars utilize a thermodynamic process. Air cools when expanding and heats when compressed. Thermal energy losses in the compresser and tankage reduce the capacity factor of compressed air systems. Isothermal compressed air energy storage ICAES plants can store energy with up to four times the energy per volume (capacity factor) of lithium-ion batteries. The capacity factor can reach up to 3.6 MJ/m3 In 2020, Dr. Reza Alizade Evrin of Ontario Tech University developed an isothermal compressed air vehicle. This prototype used low pressure air tanks and exhaust air recovery to power a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Compressed Air Vehicle
A compressed-air vehicle (CAV) is a transport mechanism fueled by tanks of pressurized atmospheric gas and propelled by the release and expansion of the gas within a pneumatic motor. CAV's have found application in torpedoes, locomotives used in situations where standard locomotives are a hazard, and early prototype submarines. Compressed-air vehicles operate according to a thermodynamic process where air cools down when expanding and heats up when being compressed and those are thermal energy losses that drain the capacity factor, however with the recent developments in isothermal compressed air energy storage ICAES plants, compressed air storage has reached 4 times the capacity factor of lithium-ion batteries with 2.7Mj/kg or 3.6Mj/m3 and in 2020 there has been developments in ICAV car or isothermal compressed air vehicle published by Dr. Reza Alizade Evrin from Ontario Tech University with a first prototype that uses low pressure air tanks and exhaust air recovery to powe ...

Hydraulic Pump
Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy Fluid statics or hydrostatics is the branch of fluid mechanics that studies the condition of the equilibrium of a floating body and submerged body " fluids at hydrostatic equilibrium and the pressure in a fluid, or exerted by a fluid, on an imm ... i.e. flow, pressure). It generates flow with enough power to overcome pressure induced by the load at the pump outlet. When a hydraulic pump operates, it creates a vacuum at the pump inlet, which forces liquid from the reservoir into the inlet line to the pump and by mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system. Hydrostatic pumps are positive displacement pumps while hydrodynamic pumps can be fixed displacement pumps, in which the displacement (flow through the pump per ...

Air Compressor
An air compressor is a pneumatic device that converts power (using an electric motor, diesel or gasoline engine, etc.) into potential energy stored in pressurized air (i.e., compressed air). By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. When the tank's pressure reaches its engineered upper limit, the air compressor shuts off. The compressed air, then, is held in the tank until called into use. The kinetic energy provided by the compressed air can be used for a variety of applications such as pneumatic tool as it is released air and the tank depressurizes. When tank pressure reaches its lower limit, the air compressor turns on again and re-pressurizes the tank. An air compressor must be differentiated from a pump because it works for any gas/air, while pumps work on a liquid. Classification Compressors may be classified according to the pressure delivered: # Low-pressure air compressors (LPACs), which have ...

Renewable Energy
Renewable energy is energy that is collected from renewable resources that are naturally replenished on a Orders of magnitude (time), human timescale. It includes sources such as Solar power, sunlight, wind power, wind, the movement of Hydropower, water, and geothermal energy, geothermal heat. Although most renewable energy sources are sustainable energy, sustainable, some are not. For example, some biomass sources are considered unsustainable at current rates of exploitation of natural resources, exploitation. Renewable energy often provides energy for electricity generation to a grid, space heating, air and water heating/air conditioning, cooling, and stand-alone power systems. Renewable energy technology projects are typically large-scale, but they are also suited to rural and remote areas and Renewable energy in developing countries, developing countries, where energy is often crucial in Human development (humanity), human development. Renewable energy is often deployed toge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Additive Manufacturing
3D printing or additive manufacturing is the construction of a three-dimensional object from a CAD model or a digital 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, with material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer. In the 1980s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and a more appropriate term for it at the time was rapid prototyping. , the precision, repeatability, and material range of 3D printing have increased to the point that some 3D printing processes are considered viable as an industrial-production technology, whereby the term ''additive manufacturing'' can be used synonymously with ''3D printing''. One of the key advantages of 3D printing is the ability to produce very complex shapes or geometries that would be otherwise impossible to construc ...

Numerical Control
Numerical control (also computer numerical control, and commonly called CNC) is the automated control of machining tools (such as drills, lathes, mills, grinders, routers and 3D printers) by means of a computer. A CNC machine processes a piece of material (metal, plastic, wood, ceramic, or composite) to meet specifications by following coded programmed instructions and without a manual operator directly controlling the machining operation. A CNC machine is a motorized maneuverable tool and often a motorized maneuverable platform, which are both controlled by a computer, according to specific input instructions. Instructions are delivered to a CNC machine in the form of a sequential program of machine control instructions such as G-code and M-code, and then executed. The program can be written by a person or, far more often, generated by graphical computer-aided design (CAD) or computer-aided manufacturing (CAM) software. In the case of 3D printers, the part to be print ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circular Industry
A circular economy (also referred to as circularity and CE) is a model of production and consumption, which involves sharing, leasing, reusing, repairing, refurbishing and recycling existing materials and products as long as possible. CE aims to tackle global challenges as climate change, biodiversity loss, waste, and pollution by emphasizing the design-based implementation of the three base principles of the model. The three principles required for the transformation to a circular economy are: eliminating waste and pollution, circulating products and materials, and the regeneration of nature. CE is defined in contradistinction to the traditional linear economy. The idea and concepts of circular economy (CE) have been studied extensively in academia, business, and government over the past ten years. CE has been gaining popularity since it helps to minimize emissions and consumption of raw materials, open up new market prospects and principally, increase the sustainability of ...
