Sam Molenaar believes that, with further optimization, the bacteria-based battery could rival the performance of lithium-ion batteries at a lower cost and with greater safety.
A rechargeable battery driven by bacteria? Lithium-ion batteries are limited by safety issues, high costs and other factors. Sam Molenaar and his colleagues from Wageningen University wanted to come up with a less expensive, more sustainable solution.
The research team combined two separate microbial energy systems. One system used bacteria to form acetate from electricity, while the other one converted the produced acetate back into electricity. Read More
Suffer from blue-green algae and dirty surface water?
Hearing the name, you might think it is something like a detergent, but think again… Meet the Oxatur, a floating ‘palace’ (here: float land) that cleans surface water 24/7 and with virtual no handling or maintenance. Smart people, the Dutch. The Oxatur is three way-system:
