TU podcast: Interview with Sine Delta

Sine Delta is developing wind power columns without turbine blades.

In this interview from the Podcast Teknisk Sett, Tech Editor Jan Moberg in Teknisk Ukeblad speak with CEO, Steven Barratt, and Commercial Director, Mirjam Engelsvold, who explain how the bladeless design works and their path toward commercialization.

Barratt, who is also the founder of the company, had 16 years of experience in various segments of the energy industry. After holding many different roles in the oil, gas, and coal sectors, he simply wanted to move away from fossil-based solutions.

Solving the Challenges

Barratt founded Sine Delta in 2021 and designed the bladeless wind catcher, aptly named Collectricity.

“Our solution is fully sustainable. It is made from 100% recyclable materials and has no large rotating blades that cause noise or pose a danger to birds. Collectricity also requires no oils, lubricants, or large foundations,” he says.

The column-shaped design can be placed in existing wind farms. It can also be installed in, for example, harbor areas, business parks, and industrial zones.

OscillationThe technology is based on a patented mechanism that converts the column's motion in the wind into electrical energy.

“There are virtually no moving parts, except for an oscillating cable. It’s a direct transfer of movement without system losses, which optimizes efficiency,” explains Barratt.

Mirjam Engelsvold states that the product is attracting attention from both small and large players in the energy industry.

The interest, she says, is based on the product's ability to generate power, along with its low cost and environmentally friendly design.

“The next step is to develop a pilot installation. It will be up before the end of the year,” says Engelsvold.
