It’s only got 178 transistors, but it’s an important proof-of-concept that’s poised to keep Moore’s Law right on track. The breakthrough, in which a basic computer was powered by microscopic chains of carbon atoms, means we may have finally found a viable alternative to silicon chips.

A new wireless power device called the Cota allows power to be transmitted wirelessly over distances of up to 3 metres, including through walls, with the system automatically charging when in range of the base station. According to startup Ossia, the device operates in a similar way to Wi-Fi, and was discovered “by accident” when experimenting with wireless transmission protocols. Cota uses Wi-Fi frequencies, and can safely deliver around one third of a normal 5V USB power source, at around 1 Watt, according to Ossia.
Although the system currently fits into a small handheld cube, its not a stretch to imagine it being shrunk down to fit into a tablet or smartphone.
