Recycling concrete with lightning

    In an effort to re-use the million of tons of building rubble produced each year, a way to recycle concrete with lightning was found.
    The lightning bolts of a short duration are more likely to pass through a solid. The idea is to produce lightning bolts and direct them to the concrete. As the lightning follows the path of least resistance, it separates the material into its fundamental components.
    A concrete recycling plant using the lightning method could be a reality in as little as two years.
