PepsiCo’s “green” bottle is 100 percent recyclable and far surpasses existing industry technologies. The bottle is made from bio-based raw materials, including switch grass, pine bark and corn husks. In the future, the company expects to broaden the renewable sources used to create the “green” bottle to include orange peels, potato peels, oat hulls and other agricultural byproducts from its

In renewable power generation the wind energy has been noted as the most rapidly growing technology; it attracts interest as one of the most cost-effective ways to generate electricity from renewable sources. Because of some challenges such as conventional energy sources consumption, pollution, global climate change and security of energy supply, significant efforts have been made to develop renewable energy

Today through Wind Volt-Amp-Reactive (“WindVAR”) electronics, voltage is controlled and regulated in real-time. Similar to conventional utility generator, WindVAR supplies reactive power to the grid at the time its needed. in a fraction of a second , regulating system voltage and stabilizing weak grids. With the ability to supply reactive power to the grid Wind VAR opens the door to

Wind energy is the world’s fastest-growing energy technology. It is a clean energy source that is reliable, efficient, and reduces the cost of energy for homeowners, farmers, and businesses. Wind turbines can be used to produce electricity for a single home or building, or they can be connected to an electricity grid for more widespread electricity distribution. They can even

It is common practice to size the machine elements, so that the maximum design stress is below the UTS (Ultimate Tensile Stress) or yield stress by an appropriate factor – the Factor of Safety, based on UTS(Ultimate Tensile Stress) or Yield Strength. The factor of safety also known as Safety Factor, is used to provide a design margin over the

When an element is stretched in one direction, it tends to get thinner in the other two directions. Hence, the change in longitudinal and lateral strains are opposite in nature (generally). Poisson’s ratio ν, named after Simeon Poisson, is a measure of this tendency. It is defined as the ratio of the contraction strain normal to the applied load divided

Finite Element Analysis (FEA) is a computer simulation technique used in engineering analysis. It uses a numerical technique called the finite element method (FEM). In this, the object or system is represented by a geometrically similar model consisting of multiple, linked, simplified representations of discrete regions — finite elements. Equations of equilibrium, in conjunction with applicable physical considerations such as

What are Plastics? Plastics are a material that is made up mainly of macromolecules, that can be made fluid by the action of heating and pressurizing, and that can be processed into end products with any useful shape you want to make. Classification of Plastics Plastics can be classified into: 1. Thermoplastics and Thermo sets 2. Amorphous Thermoplastics and Crystalline

Plastics are excellent materials with unique and very useful properties. You can produce just about anything you can imagine using plastics. Characteristics of Plastics History Of Plastics: 1. Before Plastics—Age of the Natural Resins Rubber—Tough elastic substance (light cream or dark amber colored) from the milky juice (sap) of rubber tree Ebonite—Hard black rubber; natural rubber + sulfur Gutta-Percha—Dark brown
