OpenStar Technologies are developing levitated dipole reactors for fusion energy generation. Fusion has been coined as the holy grail of energy, unleashing immense amount of energy without the long-term waste suffered by other nuclear processes. OpenStar’s concept is inspired by the same magnetic fields protecting our planet from harmful cosmic particles and presents a safe, stable approach to confining super-heated plasma’s. With decades of research and experimentation to build upon, the team is informing the clean energy revolution with each iteration of their machine. Their pathway projects grid-scale reactors ready to deploy by the early 2030’s, a feat which could power homes, businesses, and combat our dependency on fossil fuels.

Made right here in New Zealand, Future Post transforms 100% recycled waste plastic into durable, long-lasting fence posts, garden beds, and outdoor products.  Designed and tested by farmers, these posts won’t rot, split, or leach chemicals.  Helping solve our plastic waste problem, this sustainable alternative to traditional timber, is creating a cleaner, greener future. Future Post is proud to showcase Kiwi innovation and our ever growing addition to the circular economy, at the Blue & Green Technology – CleanTech Expo!

Azura Wave Power (“Azura”), is a wave energy technology development company, whose core technology is a100kW wave energy device. Each device extracts the energy from ocean waves and converts it into electricity. This core technology has two unique customer applications:

Land-based microgrids. The Azura device has integrated battery storage. When connected to a microgrid system, wave energy generation with storage helps mitigate the intermittency from solar and/or wind generation.

At-sea Desalination. The Azura wave device can also be configured with an integrated reverse osmosis (RO) unit for at-sea freshwater production.

Azura’s parent company is Energy Hydraulics Limited (EHL), based in New Plymouth, New Zealand.

DNADRV (DNA Drive) is a pioneering community science initiative that transforms everyday car travel into a tool for environmental discovery. It invites the public and organisations to swab their vehicle license plates before and after driving, capturing environmental DNA (eDNA) from insects, fungi, bacteria and plant material – turning insect splatters into biodiversity data. The project capitalizes on “waste matter”, as the buggy-grim typically removed when cleaning and destined for drains, is collected.

With a goal of collecting thousands of samples, DNADRV is not only advancing scientific research but also democratizing it – empowering citizens to choose where and when they think it is important to take sample while contributing to large-scale ecological research. These samples, paired with GPS data and machine learning, will help map species distribution across the country, offering insights into ecosystem health, biosecurity, and climate change impacts. At the intersection of environmental, social, and economic challenges, DNADRV transforms everyday human behaviour into actionable ecological data.

DNADRV highlights how low-cost, scalable technologies can revolutionize biodiversity monitoring and foster public engagement in conservation. It has also been successfully introduced to the classroom. The project is a compelling example of how innovation can emerge from the most unexpected places – even the front of your car.
