Datsun set to launch new car on July 15

Datsun -- that's right we said Datsun -- revealed teaser sketches on Tuesday of its first new generation car, which will be unveiled in New Delhi, India on July 15. Normally we don't go much for teasers, but when it's a “new” car brand, we take notice. Datsun operated worldwide starting in 1914, until the last badge was peeled off a car in 1986, being replaced by Nissan.

Koenigsegg Agera & Agera R 2012 updates

The Agera & Agera R get a raft of tweaks for 2012 Koenigsegg has revealed improvements to the Agera and Agera R for 2012, which will debut at Geneva next week. We’re not sure just how many Koenigsegg Agera R models have actually been built and delivered (or the standard Agera R, for that matter), but however many it is it’s not more than a handful. Still, standing still means going backwards – whether you’ve built a single car or a million – so Christian von Koenigsegg and his men in the snow in a shed in Sweden have been busy putting the Agera and Agera R at the cutting edge for 2012 models.

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.
