Hydro and thermal power Plants: Importance and Related problems Thermal power stations and hydropower plants project mainly address the current world’s energy needs. This article discusses the functioning of thermal power and hydropower plants. It also examines the problems of these two power plant types. The progress of civilisation has led to a worldwide increase…
Carbon Emissions in Transportation and Climate Change Road transport produces about one fifth of the world’s CO2, the main greenhouse gas (GHG) emissions an automobile and carbon dioxide emissions by Transport, Type. Even though the emissions decreased by 3.3% in 2012, they are 20.5% higher than the 1990 emissions. Transport is the world’s main sector…
This post addresses the topic of Electric car and Pollution, Carbon Footprint of Electric Cars v’s Gasoline, Low Emission Development Strategies, as well as the Electric Vehicles are good for the environment. Electric motor vehicles are admired, due to no harmed emissions on the path, as an economically sustainable option to fuel driven cars. …
Polymer Electrolyte Membrane Fuel Cell Polymer electrolyte membrane fuel cells (PEM) —also called proton exchange membrane fuel cells—deliver high-power density and offer the advantages of low weight and volume, compared with other fuel cells. Polymer Electrolyte Membrane fuel cells use a solid polymer as an electrolyte and porous carbon electrodes containing a platinum catalyst. They…
Wind up Battery Charger The Wind up battery charger is the endless independent source of power. It is the only tool you will need to charge your mobile phone batteries, notebook batteries, GPS or any other modern gadget which is in this information-packed world essential life companion. The use of wind up battery charger is…
Anaerobic Digestion An anaerobic digester is an air tight, oxygen-free container that is fed an organic material, such as Human Waste, animal manure or food scraps. A biological process occurs to this mixture to produce methane gas, commonly known as biogas, along with an odor-reduced effluent. Microbes break down manure into biogas and a nutrient-rich…
What is a Artificial Photosynthesis? Artificial photosynthesis is one of the newer ways researchers are exploring to capture the energy of sunlight reaching earth. Photosynthesis: Photosynthesis is the conversion of sunlight, carbon dioxide, and water into usable fuel and it is typically discussed in relation to plants where the fuel is carbohydrates, proteins, and fats….
Solar Thermal Power The principles of solar thermal power conversion have been known for more than a century; its commercial scale-up and exploitation, however, has only taken place since the mid 1980s. With these first large-scale 30-80 MW parabolic trough power stations, built in the California Mojave desert, the technology has impressively demonstrated its technological…
Compressed Air Cars “Compressed air cars” are cars with engines that use compressed air, instead of regular gas used in conventional fuel cars. The idea of such cars is greatly welcomed by people of the 21st century, when pollution caused by petrol and diesel is an extremely worrying factor. Engine and Technology in Compressed…
Mars Floating Wind Turbines The Magenn Power Air Rotor System (MARS Floating Wind Turbines) is a patented high altitude lighter-than-air tethered device that rotates about a horizontal axis in response to wind, efficiently generating clean renewable electrical energy at a lower cost than all competing systems. This electrical energy is transferred down the tether to a…
Floating Wind Turbines the Wave of the Future Four hundred huge offshore floating wind turbines are providing onshore customers with enough electricity to power several hundred thousand homes, and nobody standing onshore can see them. The trick? The floating wind turbines are floating on platforms a hundred miles out to sea, where the winds are…
Solar powered Wind Turbine Scientists from the University of Liverpool have upgraded an everyday solar powered wind turbine with innovative set of spinning solar blades. The entire team, led by Dr. Joe King, unveiled an innovative solution to perplex critics who state solar powered wind turbines are useful only while the wind is blowing. Well,…
Nano Generator to produce electricity with the pinch of Two fingers After six years of intensive effort, scientists are reporting development of the first commercially viable Nano generator, a flexible chip that can use body movements — a finger pinch now en route to a pulse beat in the future — to generate electricity. This…
Modern Wind Turbine Invented by Nikola Tesla and Mikhail Dolivo-Dobrovolsky in the late 19th century, the Squirrel Cage Induction Machine can be successfully used as generator in small scale hydro applications. Simple, robust and compact, it is ranked as the most reliable type of electric generator, mainly due to the small number of components. The…
