We are in the age where building materials can generate and store energy that comes from renewable sources such as wind and sun.
For homes the energy that can be stored in cement is enough to power appliances.
For roads, the energy that can be generated can charge electric cars as they travel.
But the big challenge for scientists is to be able to find a more economical method to produce this new material.
The amount of energy that can be produced and stored is proportional to the surface area of the material.
