OpenStar Technologies is a company based in Wellington, New Zealand, that is developing a nuclear fusion power reactor. It aims to build a series of devices that lead to a model able to supply electricity to the grid by the 2030s. While research has been conducted on fusion power for decades, no one has ever made a reactor capable of supplying electricity on a commercial scale. Worldwide, there are about 45 companies developing nuclear fusion reactors.
