The "grid internet" is the same concept as "grid computing". The idea is to be able to harness compute power from distributed machines located around the world (or in some cases throughout just a single company/organization).

Other terms being thrown around to describe this include: cloud computing, super computing, high performance computing (HPC), or distributed computing. All employ the power of many smaller individual workstations/servers to collectively provide a service. Google, Amazon, IBM, HP, Sun all have a strong interest in providing computing as a service.

This model does have its challenges as described above. Additional things to consider before signing on to computing as a service model is to look at disk i/o and storage needs. If your application requires lots of i/o and storage this model will not scale well. It is ideal though for heavy computational work that requires little network traffic.
