Infoworld offers up 12 ideas that could have an interesting effect on the computing world:

The warm, humming bricks that convert AC from the wall to the DC used by electronics are finally drawing some much deserved attention ? from datacenter engineers hoping to save money by wasting less energy. The waste must often be paid for twice: first to power equipment, then to run the air conditioner to remove the heat produced. One solution is to create a central power supply that distributes pure DC current to rack-mounted computers. But will cutting out converters catch on, or is the buzz surrounding DC to the datacenter destined to fizzle?

Researchers at the Department of Energy?s Lawrence Berkeley National Laboratory have built a prototype rack filled with computers that run directly off 380-volt DC. Bill Tschudi, principal investigator at the lab, says that the system uses 15 percent less power than do servers equipped with today?s most efficient power supplies ? and that there can be even greater savings when replacing the older models still in use in most enterprises. If the server room requires cooling, as it does everywhere except in northern regions in the winter, the savings can double, because the air-conditioning bill also can be cut by 15 percent.
