One of the more interesting concepts on display at the Melbourne Motor Show has been designed by a chap who sees seaweed in the future automotive landscape.

The design of the Toyota 1/X (pronounced “one-Xth”) envisages a future made of hybrid-powered cars with a fraction of the environmental footprint of even the cleanest cars on the road today.


Mr Kaida said that while the 1/X – first unveiled at the Geneva Motor Show last year – uses materials such as carbon-fibre reinforced plastic, he sees a time when even these high-tech materials will be superseded by plant-based materials.

"We used light-weight carbon-fibre reinforced plastic throughout the body frame for its superior collision safety - but that material is made from oil," Mr Kaida said.

"In the future, I'm sure we will have access to new and better materials, such as those made from plants - something natural, maybe something like paper.

"In fact, I want to create such a vehicle from seaweed because Japan is surrounded by the sea. This is my dream."

Interior space in the 1/X is similar to the current model Prius, but the catch is that the 1/X is super light. Overall weight – 420kg – is just one-third of other vehicles in the same class.

The 1/X is powered by a 500cc engine, that can be charged from a regular power point.

Its designers believe a fuel economy twice as efficient as the Prius’ can be achieved by combining a plug-in hybrid powertrain with flexible fuel technology using a mixture of ethanol and petrol.
