Typically, one sort of energy, known as “free of cost energy” is a widely discussed issue now a days. With the advent of appropriate scientific developments we can extract the energy directly from the atmosphere, and which is unlimited in supply. The discussions are mainly about its availability or non-availability, and if available the supply is unlimited or not, and if it is available the costs involved in making it available.

What it Free Energy

The discussions also involve the verification of the claims of its supporters that it would be efficient to consume resources to investigate and cultivate it, as a probable alternative energy source.

The Basic Concept

The term “free energy gadget” has multiple notations when we talk about it. One of the possible outcomes of such a gadget is that it accumulates energy from a source which is not scientifically proven, and transfers it to the other source. And off course, it is free of cost too. It may also be some sort of a machine which accumulates cost free energy or a famous uninterrupted motion vehicle. Such an uninterrupted motion vehicle as its name suggests, it will move everlastingly and will never need to be refueled. It looks beyond the reality now. But it is not beyond the reality to develop such scientific techniques which may convert energy hovering in the environment.

Scientists agree that power generation through fission reactions of atom commonly known as nuclear energy is an important alternate energy solution. This is because of its vast potential to generate power.

Efficiency of Nuclear Power Plants

Nuclear power plants consume most of their input and their performance is pretty amazing. Most preservationists show their reservations on the use of nuclear energy as a source of alternate energy source. They claim the residue material, which is in the form of radioactive gases is dangerous to environment. To address their point of concern, the efficiency of the nuclear power reactor is used as a yardstick. Nuclear power is produced at 80% efficiency, which means that output of the fission reactions is more or less equivalent to the input. This results minimal residue substances. In production of power through other sources also creates residue material. There could be no mean of power generation without leaving the residue material. Off course, there is residue material in this technology too.

Nuclear Energy-How It Works?

Tags: , , , , , , , , , , , , , , , , , , , ,


Let’s discuss first what basically nuclear energy is. Nuclear energy is a product of a fission reaction called fission. Fission is splitting of Uranium atoms and it thus yield a lot of energy. Uranium is a metal mined in various parts of the world. In 1956 the first large scale nuclear power station opened at Calder Hall in Cumbria, England. Nowadays some ships, submarines and huge cruisers are also nuclear powered.

Brief Theoretical Schematic Of Nuclear Power

Nuclear Fission produces a tremendous amount of heat which in turn is used to heat water to make steam. The steam is then used to do work in turning the turbine. The rotation of the turbine is a source to do work on the generators which in turn convert the generator energy to electric currents.

Descriptive Explanation Of Nuclear Energy Generation

Nuclear energy is made in a similar way to the fossil fuel –burning station work except that a chain reaction occurs inside a nuclear reactor and is the source of heat instead. This reactor uses uranium rods as fuel and nuclear fission generates the required amount of heat.

Nuclear fission occurs when neutrons smash into the nucleus of a uranium atom which splits roughly in half and produces heat energy. As a result of the fission of these large atoms, new, much smaller atoms are created, these being a by-product, radiation and more neutrons that are set free once the larger atom breaks.

GE And Hitachi Use Nuclear Waste As Fuel

Tags: , , , ,


Nuclear energy is the energy which is released by the nuclear reactions. It comes from splitting the of uranium and in a process which is called fission. Making use of nuclear waste is also a good idea which recently has introduced by the GE Hitachi nuclear energy. This is a joint type of committee which now makes use of nuclear waste to use it as fuel. They think that it is better to make use of the nuclear waste in creating fuel rather then wasting it.

This will also help people as a lot of fuel can be produced out of the nuclear waste.

Things To Know About Nuclear Power

Tags: , , , , ,


Nuclear power is produced by controlled nuclear reactions, which are non-explosive in nature. Commercial and utility plants currently use nuclear fission reactions to heat water to produce steam, which is then used to generate electricity. Nuclear fusion reactions are safer and generate less radioactive waste than fission. These reactions appear potentially viable, though technically quite difficult and have yet to be created on a scale that could be used in a functional power plant.

Nuclear Power – An Alternative to Fossil Fuels

Tags: , , ,


Nuclear Energy could be the next big thing to fossil fuels. According to scientists nuclear fission reaction produces massive quantities of power and if this power is harnessed well, it could mean a new dimension to energy. Nuclear plants have been built worldwide with the concept of harnessing nuclear energy for the use of military purposes as well as for other national uses. But an international consent to have nuclear power to replace fossil fuels has yet to reach the stage of development. As now there are six states in the US that have electrical energy through nuclear plants.

A small nuclear plan may generate an electrical limit of 80% which means that a single small plant equals 80% of the fossil power used to generate energy. And the other factor that supports nuclear power is its very limited waste material, which though is not a very good sign. Nuclear wastes are high radio active gases that could mean potential danger, even if it is in a small and limited amount.

Though the world had almost realized the problem of global warming but still there are some who say global warming may or may not be a problem. This “ may” in this issue is creating a lots of hurdles in taking major steps against global warming because if global warming don’t exist and the world apply too much resources to solve that problem which don’t even exist then that will be a great loss of world’s resources and billions of people will have to face then poverty.

Global Warming Solutions

On other hand if global warming problem exists and we don’t do anything about it then it will become a disastrous problem for mankind in future. So it is more important to see what steps we can take that would prove beneficial whether or not anthropogenic global warming turns out to be a problem. These steps can be termed “no regrets” policies.

How can be a “No Regrets Global Warming Policy” made? Well a global warming policy can be termed “ no regrets” as long as it:

  • When the greenhouse gases amount is reduced being emitted in the atmosphere.
  • To make less such things, prevent or reduce harm associated with global warming.
  • Providing greater capacity for dealing with problems associated with global warming.
  • Making such policies for global warming that wont affect the economy and are beneficial.

Top 10 Renewable Energy Sources

Tags: , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,


There are various environment friendly and renewable energy resources available that offer alternate source of energy and help to nullify the effects of certain forms of pollution. All these power generation techniques can be described as renewable because they are not reducing the quantity of any resources to create the energy.

Here is a list of the top 10 renewable energy resources.

# 1 – Nuclear Power

Nuclear power is obtained through any nuclear technology designed to extract usable energy from atomic nuclei through controlled nuclear reactions. Currently,  only fission nuclear method is used, though other methods might one day include nuclear fusion and radioactive decay.

The reactors heat up the water to produce steam, which is then converted into mechanical work for the purpose of generating electricity or propulsion.

Fourteen percent of the world’s electricity is produced by nuclear energy. U.S. , France, and Japan together account for 56.5% of nuclear generated electricity.

439 nuclear power reactors are in operation around the world in 31 countries. According to the figures of World Nuclear Association during 1980s one new nuclear reactor starts up in every 17 days on average, and this ratio will increase till 2015 up to one reactor every 5 days.

France gets cleanest air than any other industrialized country because of nuclear power, and also cheapest electricity in all of Europe. For reducing mass and making more energy France reprocesses it nuclear waste.

Reducing Carbon Emissions Unlikely In Near Future

Tags: , , , , , , , , , ,


According to a new study, one of the major causes of global warming, the increasing carbon dioxide emissions, cannot be stabilized unless the world’s economy collapses completely or the society successfully generates 300 giga watts of nuclear power annually.

CO2

Tim Garrett, who is an associate professor of atmospheric sciences at the University of Utah, has conducted this new study. He has said in the study that it seems unlikely that there will be any substantial near-term departure from the recently observed acceleration in carbon dioxide emission rates.

In order to stabilize the carbon dioxide emissions at current rates, approximately 300 giga watts of power, through some new non-carbon-dioxide-emitting way, is required on a daily basis.
