In nuclear fusion milestone, Japan unveils the world's largest reactor

The system is an important step forward to harnessing fusion as a clean energy source
Forward-looking: Fusion differs from fission, which is used in nuclear power plants, and it is based on the same principle that powers the Sun and stars as the hydrogen nuclei fuses into helium, releasing light and heat. Also, unlike nuclear power, fusion is intrinsically safe in that the reaction stops when the fuel supply or power source is shut down. Nor does it generate high-level long-lived radioactive waste.

Silicon-perovskite solar cells are on the verge of revolutionizing power generation efficiency

Forward-looking: Traditional solar power cells are based on a silicon semiconductor compound, which is known to have a theoretical maximum efficiency of 29 percent in converting sunlight into electric energy. However, by incorporating a second perovskite layer onto the base silicon layer, solar cells have the potential to surpass this efficiency threshold in the near future.
