Bike to the Future

There’s a new vehicle hitting the road that’s trying to bridge the gap between bicycles and cars.

We’ve seen electric assist bicycles before. But never one like this. The ELF is a recumbent tricycle, with a solar panel on top, and a trunk in the rear. It’s a single occupancy vehicle that marries the environmental benefits of a bike with the personal convenience of a car. Inventor Rob Cotter hopes his 150-pound invention entices people to reduce their dependence on single-occupancy vehicles. But at $5,000 an ELF, is that dream a possibility?

TED 2014: Meeting the real bionic man

In 1982, Dr Herr - one of the US’s most successful rock climbers - lost his way on a climb on Mount Washington.

Caught in a blizzard, he and his companion got lost and wandered for three days. With severe frostbite and on the verge of death, both were eventually rescued but there was a cost.

His companion had one leg amputated and Dr Herr lost both.

Not that you would know it as he strides confidently about the stage at the Ted (Technology, Entertainment and Design) conference in Vancouver.

He explained how the amputation affected him.

"I didn’t view my body as broken. I saw it as a call to arms to eliminate my own disability and those of others," he said.

He developed specialised limbs for climbing and returned to his sport “stronger and better”.

This odd-looking cloaking device could make you invisible to sonar

Controlling the spread of sound and how it bounces off objects is not easy. But by using a few perforated sheets of plastic and a complex algorithm, researchers at Duke University have developed the world’s first 3D acoustic cloaking device.

The device escapes acoustic detection by rerouting sound waves in such a way that both the cloak and anything beneath it appear invisible. In future, a scaled-up version of the cloak could be affixed to ships, submarines, or aircraft to help these large objects avoid sonar detection.”
