Looking like a set of bridge supports that were accidentally installed on a cargo ship, a new wind-driven system by startup CoFlow Jet promises to reduce ship fuel costs by up to 90% using stationary cylinders with no moving parts.
“What’s old is new again,” said Zha. “With the technological advancements of today, wind-assisted propulsion is an efficient alternative to diesel engines. And the major advantage is that it’s environmentally friendly – an effective way to decarbonize the shipping industry that’s responsible for about 3% of global greenhouse gas emissions. The shipping industry has had a tendency to resist change because diesel engines are so powerful but now, with pressure mounting, either willingly or unwillingly, it will have to change.”
1983! Can’t believe how old that is.
Cool to see how much of the focus is on conservation efforts
1933… This idea is almost 100 years old.
