Energy released in nuclear fusion
Research into controlled fusion, with the aim of producing fusion power for the production of electricity, has been conducted for over 60 years. It has been accompanied by extreme scientific and technological difficulties, but has resulted in progress. At present, controlled fusion reactions have been unable to produce break-even (self-sustaining) controlled fusion reactions…

Photo : High-temperature plasmas produced by the Large Helical Device (LHD) We currently use fossil fuels such as coal, petroleum and natural gas along with nuclear power to satisfy the energy requirements of our highly technology-oriented society. Fossil fuels are a limited resource, which should primarily be used as raw materials. Many problems still remain to be solved regarding…

Lockheed Martin claims that it has made a breakthrough in nuclear fusion technology that means it can build a truck-sized fusion reactor to deliver renewable energy to the masses within just 10 years. Nuclear fusion is the type of reaction that powers the Sun and hydrogen bombs. It works by getting two atoms to join together to form one (like the Spice Girls song), releasing…

Project estimates are tough for every project manager and doing it well is often the difference between consistent success and frequent failure. Let’s look at some of the fantasies surrounding project estimates and then how to do it right. Project Estimating Main Page In the real world, estimating a project’s duration and cost is a high stakes game. The client or executive…

Matter is usually defined as anything that has mass and volume, meaning that it takes up space. Matter is also sometimes defined as a general term for the substance that makes up all observable physical objects. Humans, rocks, air, atoms, and neutrons are all examples of matter. In contrast, massless particles, such as photons of light, are not considered matter, because they…

In a wide expanse of space, gravity drew dust and gas together to create the young solar system. The sun formed first from the vast material, with the planets close behind. But how did a sea of swirling particles become the brightest star in our sky? The Sun: Our Perfectly Average Middle Aged Star Credit: Space.com Although it may look empty, space is filled with gas and dust…
