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.

Jeep uncovers the 2012 Grand Cherokee SRT8 packing 465 hp

Following a one-year hiatus, Jeep is returning the fire-breathing Grand Cherokee SRT8 to the lineup for 2012, which made its world debut at the New York Auto Show. Central to the changes is a new 6.4-liter Hemi V8 engine producing 465 hp and 465 lb-ft of torque--a 45-hp and 45-lb-ft improvement over the outgoing 6.1-liter unit. Jeep says the SRT8 is good to hit 60 mph in 4.8 seconds, cover the quarter-mile in the mid-13-second range and reach a top speed of 155 mph.

Peugeot Exalt Concept: OFFICIAL

The Peugeot Exalt Concept (pictured) now officially revealed We had the first photo of the Peugeot Exalt Concept earlier in the week, but now Peugeot has caught up with that reveal and released a gallery of photos of the Exalt and details too. With strong design hints from Peugeot’s Onyx Concept – like the long bonnet, short overhangs, bold wheel-arches and crisp lines – the Exalt appears to be a five-door hatch even though it looks like a four-door swoopy coupe. Peugeot has hand-made the bare metal body panels of the Exalt and covered it in part with a ‘Shark Skin’ material which is said to improve aerodynamics and fuel consumption.
