Green Gravity Labs want to drop dense weights down mine shafts and harness the kinetic energy released to generate electricity. Once fallen the weights would be returned to elevation utilising renewable energy.
Soil-based microbial fuel cells (MFCs) are not widely used, but show some promise as clean-energy options for low-energy sensors used in precision agriculture (soil moisture and health), infrastructure monitoring (water pipes leakages) or environmental monitoring (concentration of pollutants). This latest evolution of an MFC uses a non-traditional design & readily available components to deliver a performance improvement of over 120%. Importantly, the fuel-cell was able to generate 68 times more energy than needed by the sensors - so plenty to spare for more sensors! https://scitechdaily.com/scientists-develop-new-dirt-powered-fuel-cell-that-runs-forever/
