Since scientists first demonstrated nuclear power 70 years ago, the second stage of nuclear power has remained just beyond our fingertips: nuclear fusion power. While promising, the ETA on the technology required to develop and build viable nuclear fusion has remained decades away. Until now. Probably. A company claims to have hit a critical milestone in the development of a new technology capable of generating power from nuclear fusion, according to a recent press release. Called TAE Technologies, the fusion energy developer claimed its reactors might generate energy at commercial scales by the end of the 2020s — using a novel ability to produce stable plasma at temperatures topping 50 million degrees Celsius. For comparison, this is more than twice the temperature of the core of the sun!
