Green Options

The Salamander of myth and legend: a creature which lives in water but renews its life in fire. It’s rubbish, Bunkum, steaming horse manure…  a bit like an electric car with neither plug nor solar panels.

Except no one’s told those clever boffins over at Advanced Power and Energy Sources Transportation (APET) in Hong Kong. According to them, the Salamander and the cordless EV are about to step out of myth and into reality.

APET’s revolution centres upon how zinc air batteries can power EVs. The technology is proven on the small scale: hearing aid battery adverts dominate any Google search for “zinc air battery”.

Furthermore, as zinc air batteries need only zinc, air and water to produce electricity they are likely the most environmentally friendly ones around.

However, upscaling the technology from a hearing aid to a car has always been a problem.

Until now.

The moment sustainable motoring has waited for has finally arrived: a full range of all-electric cars.

Renault has launched the world’s first range of purely electric cars at the IAA Frankfurt Motor Show 2009.  Designed to cater for everyone from a single traveller to local commerce, via 2.5 kids family cars, it’s a revolution in three important ways:

• the range is designed from scratch as a complete set of electric cars — not gas-fueled cars with an electric motor retro-fitted to give the manufacturer green kudos;
• the cars will be priced without an “electric premium,” allowing them to compete alongside gas-based engines on a like-for-like basis for the first time ever;
• most importantly, they’re real. Presented as concept cars, the Kangoo ZE is already in an advanced prototype stage, and I was lucky enough to drive it at Frankfurt.
