Electric cars can become electricity banks

Ever try to store electricity? It won't stay in a bottle, and you can't keep it in your sock drawer. So when you have a lot of it--say, when it's windy and your wind turbines are really spinning, or when it's sunny and your gallium arsenide photovoltaics are lighting up, or at night when the utility's generators can run unhindered--you have to store it somewhere.

Karmann-Ghia Coupé redesigned by Brazilian students

The winners of the Karmann-Ghia Brazilian student competition to design a modern interpretation of its classic Volkswagen Karmann-Ghia Coupé have been revealed. Over almost 60 years the German-Italian company has become an important supplier of car bodies and tooling in Brazil, but the market has lacked a model carrying the Karmann-Ghia badge since the '70s. The original coupé, which inspired the contest, was launched in Brazil in 1962 and remained in the market for 10 years before it was replaced by the Volkswagen SP – considered the first car completely developed in the country.

Red Bull do doughnuts on the Burj Al Arab Helipad to celebrate F1 title (video)

David Coulthard gives the thumbs up whilst doing doughnuts Sebastian Vettel may be cool, collected and composed behind the wheel of his Red Bull F1, but even an in-control German needs to let off steam when he’s just taken his fourth F1 drivers title in a row. So at last week’s Indian Grand Prix, Seb celebrated his title win by producing a series of doughnuts in his car on the finish line, much to the annoyance of FIA officials who fined him €25k for his celebrations. But the latest doughnuts by an F1 team won’t have the FIA up in arms (probably) even if the stunt Red Bull have pulled to mark their latest achievements will give anyone who’s afraid of heights the heebie-jeebies.
