AT SC10, I saw quite a unique and disruptive solution for cooling HPC stuff. It won SC 2009 disruptive technology of the year.
Green Revolution (GR) Cooling method of cooling datacentre is very revolutionary and innovative. According to Green Revolution Cooling, datacentre are cooled by submerging servers in dielectric fluid coolant (GreenDEF coolant).
According to its website, GR Cooling is the first to develop a complete rack and server rack solution using this method at a feasible up-front costs and high performance.
