Regular bricks can be transformed into energy storage devices

Here, a conventional brick has been transformed into an energy storage device that can power an LED light.

(CNN)Whether humans were erecting Neolithic dwellings, ranch-style homes or modern McMansions, bricks have been a favorite of builders for thousands of years.

Now, chemists have discovered new potential in these ubiquitous building blocks: Through a series of reactions, scientists have shown that conventional bricks can be transformed into energy storage devices powerful enough to turn on LED lights.
The findings were published Tuesday in the scientific journal Nature Communications.
    While scientists caution that much more development is needed before these "smart bricks" are commercially available, they say the proof of concept holds promise that could one da
