The Gist

Scientists have found that coating regular bricks with a special chemical can turn them into reusable batteries. 

The List

  • Researchers at Washington University in St. Louis, Missouri have found a way to turn bricks into batteries.
  • It involves coating bricks with a special plastic molecule that interacts with a chemical called hermite which is found in most bricks worldwide. 
  • Hermite is widely used in energy storage facilities. 
  • The coated bricks developed by researchers can power a small LED light and can be recharged up to 10,000 times. 
  • Although the prototype developed is not very powerful, it is expected that it will someday be possible to run household devices using charged bricks.
