MIT researchers create liquid battery that uses gravity to generate energy
The concept of liquid flow batteries is not new, such batteries have been around in some form since the 1970s. Taking an inspiration from these, researchers at Massachusetts Institute of Technology (MIT) are building a new, revolutionary liquid battery that uses gravity to generate power. According to the paper published in the Energy and Environmental Science journal, MIT researches suggest, the new battery will work on the principle of an hourglass and should be available as a power solution for applications across a range of industries soon.
Generally in the liquid batteries, electrons (positive and negative) are stored in liquid from and are separate within by a membrane. Increasing the capacity of a liquid battery was costly and inefficient since it required pumps, valves tanks to hold slurry filled with particles. In their battery, MIT researchers have replaced the need for pumps and tanks with a simple gravity induced system which permits battery’s rate of energy production to be altered by simply changing its angle.
Despite being a wonderful idea, this is just a proof-of-concept for now, so don’t expect your phone to have low cost, ultra-efficient, gravity powered batteries anytime soon.
