Scientists have developed a new type of fuel cell that can provide endless power through electricity harvested from dirt. A team from Northwestern University in the US say the book-sized unit could be used to power sensors used in farming, as well as remote devices in the Internet of Things (IoT). The technology works by generating electricity from naturally-occurring bacteria within the soil, offering a sustainable and renewable alternative to toxic and flammable batteries. "These microbes are ubiquitous; they already live in soil everywhere," said George Wells ... at Northwestern University. "We can use very simple engineered systems to capture their electricity. We're not going to power entire cities with this energy. But we can capture minute amounts of energy to fuel practical, low-power applications." The soil-based microbial fuel cell (MFC) is based on a 113-year-old technology first developed by British botanist Michael Cressé Potter, who was the first person to successfully generate electricity from microorganisms. It took until the 21st century for the first commercial applications to be proposed, with Foster's Brewing using a prototype to convert the yeast in brewery wastewater into electricity. The latest fuel cell was tested in wet and dry conditions to power sensors measuring soil moisture and detecting touch, outlasting the power of similar technologies by 120 per cent.

The power's out. But on a street in India, there's a cash machine still happily dispensing banknotes. Thanks, in part, to burnt cotton. For this cash machine has a backup battery inside it – a battery that contains carbon from carefully combusted cotton. "The exact process is secret," says Inketsu Okina, chief intelligence officer at PJP Eye, the Japanese firm that made the battery. "The temperature is secret and atmosphere is secret. Pressure is secret," he continues. Okina does say that a high temperature is required, above 3,000C (5,432F). And that 1kg (2.2lbs) of cotton yields 200g (7oz) of carbon – with just 2g (0.07oz) needed for each battery cell. PJP Eye also touts the possibility of improving battery performance as well as making batteries greener. "Our carbon has a bigger surface area than graphite," says Okina, describing how the chemistry of the anode in their Cambrian single carbon battery allows for a battery that charges very quickly, up to 10 times faster than existing lithium ion batteries, he claims. The battery's cathode is made from a "base metal" oxide. Although Okina won't disclose exactly which one, these metals include copper, lead, nickel and zinc. The company claims to be working on a dual carbon electrode battery, where both electrodes are made from plant-based carbon. Other researchers are looking at using materials as diverse as corn waste and melon seed shells to generate new types of electrodes for use in batteries.
