Alternative Source of Energy from Nuclear Power

Alternative Source of Energy from Nuclear Power

Many researchers believe that harnessing the power of the atom in fission reactions is the most significant alternative energy resource that we have, for the fact of the immense power that it can generate.

Nuclear power plants are very “clean-burning” and their efficiency is rather staggering. Nuclear power is generated at 80% efficiency, meaning that the energy produced by the fission reactions is almost equal to the energy put into producing the fission reactions in the first place. There is not a lot of waste material generated by nuclear fission—although, due to the fact that there is no such thing as creating energy without also creating some measure of waste, there is some. The concerns of people such as environmentalists with regards to using nuclear power as an alternative energy source center around this waste, which is radioactive gases which have to be contained.

The radiation from these gases lasts for an extraordinarily long time, so it can never be released once contained and stored. However, the volume of this waste gas produced by the nuclear power plants is small in comparison to how much NOx (nitrous oxide—that is, air pollution) is caused by one day’s worth of rush-hour traffic in Los Angeles. While the radiation is certainly the more deadly by far of the two waste materials, the radiation is also by far the easier of the two to contain and store. In spite of the concerns of the environmentalists, nuclear power is actually environmentally friendly alternative energy, and the risk of the contained radiation getting out is actually quite low. With a  relatively low volume of waste material produced, it should not be a difficult thing at all for storage and disposal solutions for the long term to be developed as technology advances.

The splitting of an atom releases energy in the forms of both heat and light. Atomic power plants control the fission reactions so that they don’t result in the devastating explosions that are brought forth in atomic and hydrogen bombs. There is no chance of an atomic power plant exploding like a nuclear bomb, as the specialized conditions and the pure Plutonium used to unleash an atomic bomb’s vicious force simply don’t exist inside a nuclear power plant. The risk of a “meltdown” is very low. Although this latter event has happened a couple of times, when one considers that there are over 430 nuclear reactors spread out across 33 nations, and that nuclear reactors have been in use since the early 1950s, these are rare occurrences, and the events of that nature which have taken place were the fault of outdated materials which should have been properly kept up. Indeed, if nuclear energy could become a more widely accepted form of alternative energy, there would be little question of their upkeep being maintained. Currently, six states in America generate more than half of all their electrical energy needs through nuclear power, and the media are not filled with gruesome horror stories of the power plants constantly having problems.

The Importance of Industrial Gears Accessories

The Importance of Industrial Gears Accessories

Accessory, as we all know is a subsidiary or additional device that adds to the value or functionality of the primary or main device. Similarly, gears accessories also include the devices or equipment which enhance the efficiency and scope of operation of the industrial gears, or rather, they are even more than that. These accessories, we can say are indispensable for the proper functioning and desired outcome, in case of the industrial gears. These gears and gear accessories work together as a complete assembly or a single unit to perform various industrial tasks. Some such accessories which hold great significance in the modern context can be named as gearboxes, gear-motors, axles, transfer-cases, winches, gear-couplings, and so. The selection of gear accessories is determined by the type of gear(s) in question. Some significant types of gears accessories are mentioned below:
1) Gearbox: It is a kind of metal casing inside which a series of gears is sealed. It is considered an essential item for the gear assembly. This equipment is also known as gear-head, gear-reducer, or speed-reducer. These boxes are available in a wide range of sizes, capacities, and speed ratios. The contemporary and advanced gearboxes are generally used for the purpose of increasing the torque, and at the same time for reducing the RPM of a prime mover output shaft. They primarily come in two types, i.e., automatic and manual.
2) Gear-Motor: This equipment provides a gear reduction system. The main benefit that this accessory provides is that by employing it, the driving shaft can be directly coupled to the driven shaft. Additional gearing is required for stepping down the motor speed. In some cases belts, pulleys, or chains are also used for this purpose. Although gear-motors are used in various applications like in case erectors, box taper, hot-melt glue pumps, conveyor drives, and so, but they found their most prevalent application in the industrial robots.
3) Axle: Axle is a metal shaft, usually fabricated from steel on which the locomotive wheels are mounted. Besides holding the wheels on the gauge, this equipment transfers the load from the axle-boxes to the wheels. Automobiles are usually equipped with the front or rear split axle. Each driven wheel is attached to an individual shaft, having differential and universal joints between the two shafts. It is this differential and split axle that permits the adjacent wheels to rotate at differential speeds when the vehicle is taking a turn.
4) Winch: Winch is basically a crank with a fixed handle for providing motion to a machine. Winches are used for converting the high-speed, low force input of the handle into low-speed, high torque output at the drum. This equipment makes use of totally unconventional kind of tooth forms that are entirely different from those generally used in automobile and power transmission applications. The winches turn thousands of times in their lifetime and they never got too heated to malfunction.
5) Gear-Coupling: It is a power transmission coupling that makes use of a hub with gear teeth on the outside diameter of the input shaft. This coupling is usually fabricated from metal and requires lubrication. It is very rigid torsionally, and can produce high torque through relatively small packages. These couplings can either be directly mounted on the shaft or can be fixed with the shaft with a setscrew, depending upon the nature and type of application. Gear-couplings are basically flexible and rigid.
Given above are few of the primary types of gear accessories that are used in various industries these days. There are a lot more types of accessories and other gearing equipment. For getting comprehensive and detailed information on various types of gears, gear accessories, drives, and materials, you should visit Gears Manufacturers Marketplace.
