Golf carts have already inspired off-road light EVs.
In Maine, meanwhile, the 50,000 tonnes of lobster shells discarded annually provided a local research team with the drive to create a sustainable alternative to existing golf tees.
First, the team pulverised the shells and mixed them with a natural binding agent and food dye. Next they developed a lab injection moulding system dedicated to processing the material with its special flow behaviour.
The resulting tees decompose within 30 days while simultaneously fertilising the ground. If manufactured at scale, they could replace their plastic or wooden counterparts. A billion of the latter are jettisoned each year in America alone.
