New environmental rules are making ocean shipping more expensive. Commodities giant Cargill is betting a return to sail power could cut its fuel costs by 30%.

BAR TechnologiesThe commodities giant Cargill will launch the first ocean-going tankers fitted with BAR Technologies' "wing sails" by 2022.

The new sails, which look more like giant lint brushes than anything an old-school sailor would recognize, are the product of a UK engineering company headed by a pair of veterans of McLaren's F1 team. "WindWings enables a 30% cut in heavy marine fuel oil, and therefore emissions, for vessels now," Cooper said.

It will take at least a decade for the industry to decide which sustainable fuel to opt for and build the required port, supply, and storage infrastructure to supply a new fleet of ships. So it is desperate for solutions that cut emissions in the next few years. WindWings were designed using computer modeling and simulations, including advanced optimization that uses neural-network training and computational fluid dynamics.
