Nuclear fusion is pure solar energy. Deep within a star, the atomic nuclei of light elements fuse, generating vast amounts of energy in the process. For a long time now, scientists have wanted to use such fusion power here on earth, because it promises to provide us with a virtually inexhaustible source of clean energy.
The new shape of fusion: Two experimental fusion reactors, MAST outside Oxford and NSTX outside Princeton, are being upgraded to test whether their round shape is more effective at confining burning plasma than the doughnut shape of ITER and other tokamaks. | Science/AAAS | News
California’s Tri Alpha Energy company claims fusion breakthrough, by continuing progress toward a viable alternative fusion reactor. Fusion reactors reach hydrogen atoms at high temperatures, like these on the Sun. Tri Alpha heats their sample with hydrogen and boron, up to 10 million degrees Celsius (18 million degrees Fahrenheit). more....
The world's largest bid to harness the power of fusion has entered a "critical" phase in southern France. The Iter project at Cadarache in Provence is receiving the first of about one million components for its experimental reactor. Dogged by massive cost rises and long delays, building work is currently nearly two years behind schedule.
