Ken Cole, a Milwaukee-based psychologist and surfer, is working with engineering professors to create the world’s first surfboard product of leaves. And he’s hoping that by this summer season, he’ll be using the chilly waves of Lake Michigan on his bio-based board.
Cole’s journey to shaping surfboards with sustainable, unhazardous supplies started in 2018. After years of feeling that the board beneath his ft was interrupting the distinctive reference to nature that browsing gives, he determined to design his personal.
Utilizing his storage as a workspace, he began handcrafting boards with sustainability in thoughts, utilizing as many natural and eco-friendly supplies of their building as potential. And Greenhouse Surfboards was born. The model’s been making customized surfboards ever since.
However that is the primary time that Cole has used leaves as the first materials for certainly one of his surfboards. And he’s received excessive hopes for the tip consequence.
Greenhouse Surfboards: How They’re Made
Industrial factories crank out surfboards in simply minutes. In Cole’s workshop at Greenhouse Surfboards, each one he makes takes roughly 20 hours. He sculpts his creations utilizing jute, basalt, hemp, bioresin, and repurposed wooden, as a substitute of fiberglass or carbon, which is used on most traditional surfboards.
For the art work, Cole fastidiously lays out items of jute and strips of material from espresso baggage given to him by Al Liu at Colectivo Espresso Roasters. The look is immediately recognizable and offers his boards a basic, natural type of really feel.
However the issue he’s by no means been capable of work round is on the core of his craft. Actually, the core of surfboards is constructed from polyurethane (PU) foam, and his boards are not any completely different. Regardless of all of the natural supplies Cole makes use of within the outer layers of the boards, PU foam nonetheless accounts for 97% of their mass.
“I acknowledged the restrictions in sustainability when you’ve got a surfboard with a foam core,” Cole stated. “And we’re at a spot the place the established order received’t work on the subject of the setting. We simply can’t proceed to depend on petroleum-based merchandise.”
So Cole continued looking. He needed a solution — an answer that enable him to switch PU foam with one thing natural. It must be light-weight. However it might additionally want to carry stability. And it must be extraordinarily buoyant.
The board maker thought-about a number of alternate options. However then one evening, he stumbled upon a rubbish can crammed with bio-based disposable dinner plates and his world modified.
Leaving PU Behind
Cole was visiting a buddy who based the eco-dishware firm Patra, a model that makes dinnerware out of palm leaves. And when Cole seen some discarded Patra plates within the trash, he began rifling by way of them. He was blown away by the pure materials’s energy and flexibility.
He questioned whether or not it may work to make surfboards out of it as nicely.
Cole then reached out to professors on the Milwaukee College of Engineering (MSOE) who specialised in composite supplies. They helped him gauge the potential for utilizing palm leaves in surfboards.
Collectively they checked out analysis and information on the traits of different leaf-based composites, akin to jute and hemp. A number of case-study objects had been created from the palm leaf-based composite, together with the world’s first “skateboard product of leaves.” And it labored amazingly — the deck was sturdy, smooth-rolling proof of the pure materials’s structural capabilities.
Cole was gaining confidence that palm leaves would be capable of maintain the standard use of a surfboard.
The Subsequent Evolution of Leaf Boards
The mission to construct a greater board gained much more momentum when Cole related with Ted Burdett and the Nice Lakes Surf Craft Undertaking (GLSCP).
“Our purpose is to have fun the inventive work of surf craft shapers who deal with constructing craft for the Nice Lakes,” stated Burdett, a professor on the College of Illinois Chicago College of Industrial Design. “Ken Cole was one of many shapers we had been all conscious of earlier than the challenge started, having seen his stunning boards on Instagram … Ken’s work with regionally sourced, various supplies appeared to align with our thesis.”
The GLSCP group has been offering help within the technical sides of building and computer-aided design and computer-aided manufacturing know-how. Burdett is at present constructing a digital mannequin of the palm leaf board utilizing these instruments.
Burdett explains how the pure composite will be fashioned right into a flat materials — or cold-molded into types with compound curvature. Cole’s palm leaf surfboard will use each.
Paired with a bio-based thermoset resin, the consequence will likely be a powerful and superbly engineered materials.
“We’re type of sharing our abilities,” Cole stated. “Mine is the imaginative and prescient, the thought of the idea, the method. Working with MSOE and now Ted Burdett, it’s a novel collaboration between myself and two establishments.”
Design
As for the design of the surfboard-in-progress? Burdette is modeling it after certainly one of Cole’s unique Greenhouse Surfboards creations: a 9-foot-6-inch single-fin pig longboard.
“Utilizing [Ken Cole’s] kind, I’m constructing a digital mannequin in Fusion 360 utilizing a board modeling technique I developed by way of the pandemic,” Burdett explains. “Whereas the interior construction of the surfboard is just like designs of the late Nineteen Twenties, the rail-building technique is considerably new. Impressed by war-time picket boat building by way of a way referred to as ‘chilly molding,’ the rails will likely be molded right into a hole form — yielding a ton of energy with much less weight.”
Palm Leaf Board: Obtainable within the Future (Possibly)
For these questioning once they’ll be capable of get their arms (and ft) on an all-natural surfboard, time will inform. The scalability of this board and the supplies it’s made out of stays to be seen. However Cole hopes to be using his prototype by this coming summer season.
Till then, this idea will proceed to encourage folks. It’s illuminating the eco-potential of latest supplies and sparking extra concepts in sustainable design and manufacturing.
Engineers like Burgette have an interest, not solely in how palm leaves carry out as a surfboard but additionally in how they could work for different functions as nicely.
“If [this material] will be fashioned into a powerful but gentle craft that may glide by way of waves, it will possibly simply carry the load of an individual as furnishings,” Burdett says. “If it will possibly endure the frigid waters of the Nice Lakes throughout winter classes, clearly it will possibly turn out to be a sturdy part in objects for transportation.”
Cole, too, is optimistic in regards to the future makes use of of his patented eco-friendly materials.
“A surfboard is only one factor,” he stated. “Each little effort, each little shift in a special route, retains us right here on this planet slightly bit longer.”
