IBM has unveiled a new supercomputer called Hydro-Cluster that uses water to cool down the device and reduce energy consumption. IBM claims that data centers using Hydro-Cluster supercomputers can reduce their energy consumption by 40 percent and use 80 percent less cooling. They estimate that water can be up to 4,000-times more effective in cooling computer systems than air.

Help solve the worlds problems by donating your unused CPU cycles to solve complex computational challenges. Known as grid or distributed computing it allows you to share your CPU to perform units of work when your PC is sitting idle. Most machines actually sit idle for a majority of the time. The idea is to take advantage of that idle time and scavenge cpu cycles.

Grid computing has been around for over 12 years now and its advantages are many. Grid computing can be defined in many ways but for these discussions let's simply call it a way to execute compute jobs (e.g. perl scripts, database queries, etc.) across a distributed set of resources instead of one central resource. In the past most computing was done in silos or large SMP like boxes. Even today you'll still see companies perform calculations on large SMP boxes (e.g. E10K's, HP Superdomes).
