The current AI race has reached a bottleneck that can be relieved only by new sources of electrical generation. Read more ...

Modern re-run shows that Arthur Ruhlig’s conclusions, which probably influenced early thinking about fusion energy, were ...

An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...

They have discovered that gamma rays, produced during the deuterium-tritium nuclear reaction, can serve as a precise and alternative means of measuring the power output of new fusion reactors.

Deuterium (heavy hydrogen), for instance, has one proton and one neutron in its nucleus. When two deuterium nuclei are fused together, they form a helium nucleus (two protons and two neutrons ...

Many heavy atoms form from a supernova explosion, the remnants of which are shown in this image. NASA/ESA/Hubble Heritage ...

Google has agreed to purchase 200 megawatts of fusion energy from Commonwealth Fusion Systems (CFS). That's assuming, of ...

Deuterium/helium-3 fusion creates far fewer radioactive neutrons. However, creating and sustaining such a reaction is much more challenging than conventional deuterium/tritium.

Notably, the method used by this team to measure the gamma-ray-to-neutron branching ratio could also be adapted and applied to other fusion reactions that do not produce neutrons, such as proton ...

Theoretically, a deuterium/helium-3 fusion reaction would liberate 164.3 megawatt-hours of energy per gram of helium-3 – and crucially, neither the helium-3 or its reaction products are ...
