摘要

Recent collaborations in air power include Cargill's partnership with SkySails and Wessels' with Enercon; however Finland based Norsepower CTO Jarkko Vainamo and CEO Tuomas Riski reckon their product is leading the pack and offers a cost effective solution that fits in with vessels' existing technology. Discussions with new potential customers are going on all the time, says Tuomas Riski.
