In an effort to clean up Africa's dirty and diesel-reliant mobile network, Swedish start up Flexenclosure has designed a green version of a cellular base station. Called the E-site, it runs primarily on wind and solar power and utilises an intelligent operating system that adapts to local conditions.
The new design comes at the request of Ericsson, which wanted an alternative to a purely diesel-run base station. Those consume roughly 20,000 litres (5,283 gallons) of diesel per year - an increasingly costly expense with rising world energy prices.
The E-Site draws its power from a wind turbine in the network tower and solar panels on the roof. Clean energy sources charge a battery that then powers the base station at night. The E-site also has a small diesel generator, just in case the batteries run out.
What's even more amazing is the E-site's operating system, which can learn to adapt its power-generating techniques to different situations. For instance, if the batteries are running low at night, but the system knows the sun will rise soon, it can decide to wait it out until morning rather than head straight towards the diesel. Good thinking, E-site! [Cnet]
