Photosynthesis: Photosynthesis is the process by which plants, some bacteria, and some protists use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the “fuel” used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. They release molecular oxygen and remove
Polymer electrolyte membrane (PEM) fuel cells—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. PEM fuel cells use a solid polymer as an electrolyte and porous carbon electrodes containing a platinum catalyst. They need only hydrogen, oxygen from the air, and water to operate and do
The Wind up battery 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 easy and being that it is totally portable and independent
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 effluent. Biogas fuel is a flammable substance
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. Using only 3 percent of the sunlight that reaches
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 and economic promise. With few adverse environmental impacts
