Sentences with phrase «hydrogen fusion reactions»

Not exact matches

NIF's goal is to focus the intense energy of 192 giant laser beams on a BB - sized target filled with hydrogen fuel, fusing the hydrogen atoms» nuclei and releasing many times more energy than it took to initiate the fusion reaction.

Human male sperm and human female eggs are an - alogous to the millions of tons of inactive deuterium floating harmlessly in the ocean but combine them in a fusion reaction, they instantly become the expanding energy of the Sun found in all stars as they continuously fuse more hydrogen making the const - ituents of all human life..

This «quarksplosion» would be an even more powerful subatomic analog of the individual nuclear fusion reactions that take place in the cores of hydrogen bombs.

Scientists can already trigger limited fusion reactions in the lab and abundant (if somewhat uncontrolled) reactions in a hydrogen bomb.

If enough material, mostly in the form of hydrogen gas, accumulates on the surface of the white dwarf, nuclear fusion reactions can occur and intensify, culminating into a cosmic - sized hydrogen bomb blast.

In a basic fusion reaction, hydrogen atoms collide, creating helium and releasing energy.

A 10-fold increase in temperature would bring them into the realm of sparking reactions in conventional fusion fuel, a mixture of the hydrogen isotopes deuterium and tritium, known as D - T.

Achieving fusion — nuclear reactions that have the potential to produce copious, clean energy — requires heating hydrogen fuel to more than 100 million degrees Celsius, causing it to become an ionized gas or plasma.

The breakthrough is in magnetic confinement fusion, in which hydrogen is heated until it is a plasma 10 times hotter than the centre of the sun, and held in place by strong magnetic fields until fusion reactions occur.

According to standard models of stellar evolution, around that time the sun will largely deplete the hydrogen reserves in its core and begin to balloon as its fusion reactions migrate outward.

The electron beam heats the plasma ball, igniting fusion reactions between the hydrogen and boron; these reactions pump more heat and charged particles into the plasma.

The control of nuclear fusion — the reaction that powers stars and hydrogen bombs — would permanently solve the world's energy problems, not to mention a few geopolitical ones.

They believe that the experiments, in which laser beams power a fusion reaction, could reveal secrets of the hydrogen bomb.

In the meantime, however, the exposed core becomes a violent scene of fusion reactions among remaining hydrogen and helium nuclei, which release a torrent of energetic photons, mostly in the form of ultraviolet rays.

Long before descending into scientific infamy, Hoyle made what should have been a lasting contribution with a 1954 Astrophysical Journal paper laying out a process by which stars heavier than 10 suns would burn hydrogen and helium at their cores into heavier elements through a progressively hotter series of nuclear fusion reactions.

Within the Sun's core, nuclear fusion reactions take place, with hydrogen nuclei being fused into helium nuclei.

At the center of the Sun, where its density reaches up to 150,000 kg / m3 (150 times the density of water on Earth), thermonuclear reactions (nuclear fusion) convert hydrogen into helium, releasing the energy that keeps the Sun in a state of equilibrium.

All stars, including our sun, will eventually run out of the hydrogen gas that fuels the nuclear fusion reactions in their cores.

Currently only a tiny speck of hydrogen fuses, and for the laser approach to work, the fusion reactions would have to propagate through the rest of the hydrogen fuel.

In stars, the nuclear reactions are primarily the fusion of hydrogen nuclei to form helium nuclei.

(* Actually, the fuel consists of solidified «heavy hydrogen» — deuterium and tritium, which is hydrogen with extra neutrons that can fly off to create energy in the fusion reaction.)
