Many experts believe fusion energy is the future of limitless clean energy - and one Wellington-based team aims to help New Zealand access this.

OpenStar Technologies is working on a 'levitated dipole' fusion reactor prototype, designed to recreate the process where hydrogen atoms 'fuse' to make helium and release energy. 

Founder Dr Ratu Mataira was drawn to the possibilities that come with fusion energy.

"Fusion has the advantage of being incredibly useful, and the challenge of our time is climate change. So we need to continue to look at every possibility to help fight that challenge, and I think fusion is one of those options."
