China’s Quantum Satellite Dispatches Transmissions Over a Record Distance of 1,200 Kilometres

A Chinese quantum satellite has dispatched transmissions over a distance of 1,200km (746 miles), a dozen times further than the previous record, a breakthrough in a technology that could be used to deliver secure messages, state media said on Friday. China launched the world’s first quantum satellite last August, to help establish “hack proof” communications between space and the ground, state media said at the time. The feat opens up “bright prospects” for quantum communications, said Pan Jianwei, the lead scientist of the Chinese team, Quantum Experiments at Space Scale…

£1 Fuel Cell Creates Electricity From Urine

A miniature fuel cell costing as little as a £1 can generate electricity from urine. The microbial fuel cell could be a lifeline for people in remote areas – creating a renewable and carbon-neutral way of generating power. The technology was developed by researchers at the University of Bath, Queen Mary University of London and the Bristol Bioenergy Centre. The fuel cells use natural biological processes to turn organic matter – like urine – into electricity. When urine passes through the microbial fuel cell, bacteria inside it generates electricity. This…

Saudi Arabia to build world’s tallest tower, reaching 1 kilometer into the sky

Dubai, long champion of all things biggest, longest and most expensive, will soon have some competition from neighboring Saudi Arabia. Dubai’s iconic Burj Khalifa, the world’s tallest building, could be stripped of its Guinness title if Saudi Arabia succeeds in its plans to construct the even larger Kingdom Tower in Jeddah — a prospect looking more likely as work begins next week, according to Construction Weekly. Consultants Advanced Construction Technology Services have recently announced testing materials to build the 3,280-feet (1 kilometer) skyscraper (the Burj Khalifa, by comparison, stands at…
