Win one of six pairs of Polaroid sunglasses

By James Popsys Competitions 30 June 2009 09:30 The summer is here and CAR Online has teamed up with Polaroid sunglasses to give away six pairs of its range-topping shades. Click here to enter our competition. Polaroid was the inventor of polarising lens technology in 1930s, so all the sunglasses we’re giving away feature polarised lenses, which deliver 100% UV protection and block glare, rather than just making things darker.

New tech suggests windowless cars are on the horizon

For years students have presented windowless car projects, explaining how the view from outside would be projected within the interior. Now an aerospace company has created the technology that could hold the key to turning the dream into a reality. Spike Aerospace's upcoming S-512 supersonic business class jet replaces its windows with high-definition screens displaying footage of the panoramic views streamed live from micro cameras on its fuselage as tests have unsurprisingly shown that passengers are a little uneasy about not being able to see outside.

Tomorrow's world: lightweight carbon composites

Once all the dust settles on The Great Battery Farce (the idea that the world's ills will be taken care of by sticking a battery in everything that moves and charging it up) we may eventually face up to the fact that the best way to move something around more economically, is to move less of it. That means making things lighter, a lot lighter. Car makers are working on it and manufacturers like Audi and Jaguar have already become masters in bringing aluminium to the mass production.
