Operational costs must also be factored inprice of jack hammer. Pneumatic models require a steady supply of compressed air, which means investing in an air compressor and paying for energy consumption. Electric models, on the other hand, consume electricity, which can add up over time. Maintenance and repair costs, although variable, can significantly impact the total lifecycle cost of a jack hammer.

In recent decades, carbon aerogels have been widely explored by using graphitic carbons and soft carbons, which show advantages in superelasticity. These elastic aerogels usually have delicate microstructures with good fatigue resistance but ultralow strength. Hard carbons show great advantages in mechanical strength and structural stability due to the sp3 C-induced turbostratic “house-of-cards” structure. However, the stiffness and fragility clearly get in the way of achieving superelasticity with hard carbons. Up to now, it is still a challenge to fabricate superelastic hard carbon-based aerogels.
