Researchers from the universities of Michigan and Pennsylvania are using wax to investigate a new kind of smartphone and tablet processor to address overheating issues related to chip speed. Michigan professor Milo Martin and his collaborators think microprocessors can achieve significant performance upgrades if they are built to make intermittent bursts of unprecedented speeds and then allowed to rest. The wax or paraffin would protect the chips from overheating during "computational sprinting" by absorbing the heat. The researchers believe computational sprinting can lead to energy savings, with Martin noting "there are actually some situations where it makes more sense to operate in sprint and rest." Although it may take five to 10 years for their model to be incorporated into cellphones, Intel engineers Per Hammarlund and Steve Gunther say computational sprinting aligns very closely with the way people use their cellphones. "You appreciate having really snappy responsive system behavior for very short bursts of time," they say. "And other than that, you really want the system to consume no power."
