System draws power from daily temperature swings

Thermoelectric devices, which can generate power when one side of the device is a different temperature from the other, have been the subject of much research in recent years. Now, a team at MIT has come up with a novel way to convert temperature fluctuations into electrical power. Instead of requiring two different temperature inputs at the same time, the new system takes advantage of the swings in ambient temperature that occur during the day-night cycle.

Give robots an ‘ethical black box’ to track and explain decisions, say scientists

Give robots an 'ethical black box' to track and explain decisions, say scientists

As robots start to enter public spaces and work alongside humans, the need for safety measures has become more pressing, argue academics. Robots should be fitted with an “ethical black box” to keep track of their decisions and enable them to explain their actions when accidents happen, researchers say. The need for such a safety measure has become more pressing as robots have spread beyond the controlled environments of industrial production lines to work alongside humans as driverless cars, security guards, carers and customer assistants, they claim.
