Japanese Eco-Friendly Building Demolition Method Harvests Energy As It Destroys

Rather than using cranes to take the building apart from the outside, they start from the inside, taking the structure apart floor by floor from the top down. A crane inside the building lowers materials harvested from each floor to ground level, generating electricity to power other equipment in the process. So with Tecorep, higher buildings are actually an advantage, since the crane can generate more electricity lowering materials over longer distances. — popsci.com
