Flying taxi in Paris - A start-up has reportedly found a solution in the fight against pollution in Paris. The Bubble, a "flying taxi", is powered by electricity and lifts out of the water on "wings" – and boasts green credentials such as being noise and pollution-free. It costs around €200,000 to build and can reach speeds of up to 18 knots (20.7mph). Test voyages in Paris are limited to a maximum speed of 18.6mph.
The Seabubbles start-up launched a four-day test run on the Seine on Monday. However, the company says its journey has not all been plain sailing. During a preview on Monday morning before the official tests launched, Paris river police ordered the Bubble to stop its activity.
