A team from Eindhoven University of Technology in Eindhoven, Netherlands have developed a four-seater vehicle that is made from bio composites.
They wrote on their website: "Lina is a four-seat electrical city car. Lina weighs only 300 kilograms, making her a very efficient car. This weight is realised using an innovative structural bio composite material made from flax.
"This material has a structure that is comparable with carbon fiber, but more than 90 percent biological. A sandwich panels is created by pressing two composite sheets against a 95% biological honeycomb PLA. These sandwich panels will be combined to form Lina's chassis."
The car runs off a battery pack can be unlocked using a person's smartphone.
They added: "Lina will use a redesigned battery pack from Nova, enabling easy battery swapping and the possibility to use new batteries technologies. Another feature making Lina future proof is the NFC tags in her doors.
"Lina can be unlocked with your smartphone. This enables the car to recognize the user and adapting to the user's personal settings like a music playlist or phone contacts. This feature makes Lina perfect for car sharing services.
"Lina is the next step to what we think is the car of the future. Sustainable materials, efficient drivetrain and still practical due to its four seats and small dimensions."
The car hasn't been approved to go on the road yet as it will just disintegrate if it crashes.
