Trio electric complete round the world

February 25, 2011, Last updated at 14: 19 GMT An Australian three was among the runners a trio of emission-free electric vehicles have pulled up silently in Geneva, completing a journey around the world to promote green energy.

A three Australian German, a scooter and a Swiss moto Monotracer arrived at the UN European headquarters in Switzerland.

Had taken 188 days to cover 27,000 km (16,800 miles), 80 days that were actually spent.

The main obstacle they faced was charging in remote areas.

"It was very difficult in some places, certainly for our team members in Russia and China," said Alexandra James, one of 12 volunteers who took their turn to guide the two-seater Australian bright green, dubbed Travolta.

"They were straight in the sheet feeder cable in certain situations, because he was the only way to get a reliable energy source-it was a challenge," he told AFP news agency.

Sylvie Motard, the United Nations Environment Programme, said the "race to Zero" had shown that might be self powered by clean, renewable energy "as effective as gasoline vehicles, but without emissions".
