Charge cycle for the Cladophora-polypyrrole battery
The battery is produced by coating the algae with a thin layer of polypyrrole (Images: Gustav Nystrom, Aamir Razaq, Maria Strømme, Leif Nyholm, Albert Mihranyan)
Algae blooms are unpleasant and unpredictable phenomena that arise quickly and strike seas and oceans, often causing serious problems to local ecosystems. But, in an effort to try and find a use for such algae, a research team from Uppsala University, Sweden, has recently managed to design a record-breaking "green" lightweight battery that is incredibly easy to produce and might just even out the environmental consequences of these blooms.
