The singlet fission experiment captured energy with high efficiency. (Kyushu University) Scientists are always pushing the boundaries of solar cell efficiency – how much of the available sunshine gets ...

This article was originally published on The Conversation. Read the original article. Over Christmas vacation in 1938, physicists Lise Meitner and Otto Frisch received puzzling scientific news in a ...

Nuclear fission is a substantial part of the world’s energy mix, but out in the broader universe, fission is much harder to come by. Now, a new study from Los Alamos National Laboratory and North ...

A clear comparison of nuclear fission and fusion, explaining how each process releases energy and why scientists are studying ...

Can we have our cake and eat it too? Can we have a non-thermal nuclear propulsion minimizing waste heat? * Yes. By making the fuel into dust. There is the original dusty fission fragment version.

Deep Fission is betting that the safest place for a nuclear reactor is not behind thicker concrete walls but a mile beneath our feet. The California startup wants to sink compact power plants into ...

Novel propulsion ideas for moving around space seem like they're a dime a dozen recently. Besides the typical argument between solar sails and chemical propulsion lies a potential third way—a nuclear ...

Russian scientists have published a concept for a new kind of nuclear reactor. It’s a hybrid reactor, meaning it includes both fusion and fission, and it runs almost exclusively on thorium instead of ...

More than 110 countries and countless companies have pledged to reach net-zero emissions by 2050, but can they get there with existing technologies? Probably not. But the net-zero equation is complex.
