At its core, a tunneling tool creates a 'virtual pipe' through which data packets can travel, often masking their true origin or destination. This is particularly useful when dealing with firewalls or network restrictions that might block certain types of traffic. For instance, a common application is the use of SSH (Secure Shell) tunneling to securely access resources on a remote network by encapsulating non-secure protocols within a secure SSH connection.

The concept of gas rock drilling, commonly associated with hydraulic fracturing or 'fracking,' has revolutionized the global energy landscape. It involves the use of specialized drills that can penetrate hard, impermeable rock layers such as shale, sandstone, and coal seams. These rocks, often rich in hydrocarbons, have long been considered inaccessible due to their tight structure. However, with advanced drilling techniques, they now hold immense potential as energy sources.
