Today on In Case You Missed It: University of Michigan researchers spent years creating a water-harnessing river turbine to create electricity, called the VIVACE. It's the first time electricity appears to be effectively generated in slower rivers rather than oceans, but that's because the developers used physics to get turning turbines to agitate the water enough to create more energy for their neighboring cylinders. It's an as-yet prototype but a promising new development in the realm of water-powered electricity.
