A car made from seaweed - why didn't we think of it sooner?
Japanese car manufacturer Toyota is planning to build a car from seaweed, and it could be in a showroom near you within ...oooh... 15 years?
According to the report in Wired: 'A kelp car is not as far-fetched as it might sound. Bioplastics are being used for everything from gift cards to cellphone cases. Demand for the stuff is expected to hit 50 billion pounds [22.7 billion kilogrammes]annually within five years.'
