Watch this 'Fast and Furious' remote control tribute

The convergence of great remote-controlled cars and super cheap video cameras has brought us more RC spoof videos than we know what to do with. But this one stands head and shoulders above the rest. Vax Studios put this “Fast and Furious” homage together and dedicated it to the late Paul Walker.

Porsche Battery – a mere £1200

The rather expensive Porsche Lithium Ion Battery Car batteries have been roughly the same shape and size – and utilised basically the same lead-acid technology – for years. They’ve got better, as you no longer need to top them up with distilled water at regular intervals (I’m showing my age now), and they are less prone to going flat. But that probably has more to do with alternators replacing dynamos than the batteries themselves.

RCA Citroen/Exa Double Challenge project

Second year students at the Royal College of Art in London revealed a series of projects at their interim degree show last week. Developed in collaboration with French automaker Citroen and the Exa Corporation, a leading supplier of aerodynamic software, the Double Challenge project asked students to design an ultra-compact model that could establish a unique Citroën e-vehicle aesthetic for the future, all while adhering to certain aerodynamic criteria that would not only reduce energy consumption and ensure stability at speed, but also visually communicate efficiency through its design. The project, which kicked off in October last year, was closely followed by representatives from Citroen and Exa, who examined each of the projects and chose a winner, Heikki Juvonen, at the event last week.
