Drawing on the layered design of tear-inducing onions, scientists have created a new super capacitor that is powerful enough -- and cheap enough -- to replace the larger, heavier capacitors used in consumer electronics such as computers and cells phones.

If commercialized, the new super capacitor could be fully charged in a second and, coupled to a normal battery, provide enough energy to power a cell phone for weeks or a laptop battery for days.

One of the key selling points of solid state drives has been that they use less power than hard disk drives. The claim has seemed plausible because solid state drives have no moving parts, while hard disk drives have a number of moving components.

The Tom's Hardware review, however, says: "While conventional hard drives may operate at relatively low power when little movement is required...flash based drives do not. They will draw their maximum power level constantly when in use, and as a consequence, simply spend more total time drawing maximum power than conventional drives."
