Renault/Lovegrove Studio Twin'Z concept

The Renault Twin'Z concept is a collaborative project with British designer Ross Lovegrove, filling the fifth stage in Laurens van den Acker's 'lifecycle' – Play. It's currently on display at the Milan Salone. Essentially previewing the all-new, rear-engined Twingo co-developed with Daimler, the Twin'Z takes this relatively humble city car and, thanks to the input of Lovegrove, it appears to have taken on an organic nature, which shouldn't be unexpected to those familiar with his work.

Algae-powered street lights eat CO2

Algae powered street lighting (great Photoshop) A French biochemist – Pierre Calleja – has developed a street lighting system using micro algae that absorbs CO2. The need to reduce CO2 in the atmosphere is contentious - to say the least – but as long as governments use CO2 as a stick to beat motorists and empty their bank accounts it’s sensible to look at ways of ‘balancing’ the CO2 emissions of cars. French biochemist Pierre Calleja thinks he’s come up with a solution that would neutralise CO2 emissions from cars by cancelling it out with his micro-algae lighting.

Toyota Camatte 57s concept

You may remember last year we reported the unveiling of a customizable, modular little concept car called the Toyota Camatte at the Tokyo Toy Show. This year Toyota has returned with an updated version called the Camatte 57s with more scope for families to personalize their space-framed little machines with a total of 57 external panels (as its name suggests) as well as the removal of the roof which apparently "adds to the fun factor and allows everyone on board to enjoy the colorful exterior they have created". Like last year's car the driving position can accommodate both adults and children with gown-ups sat in the right rear seat able to intervene should the infant pilots go astray.
