"Your next laptop could have a continuous power battery that lasts for 30 years without a single recharge thanks to work being funded by the U.S. Air Force Research Laboratory. The breakthrough betavoltaic power cells are constructed from semiconductors and use radioisotopes as the energy source. As the radioactive material decays it emits beta particles that transform into electric power capable of fueling an electrical device like a laptop for years."

Intel recently released a new PowerTOP utility that helps discern which executables are consuming the most power. Additionally, the "tickless" kernel feature that was released in 2.6.21-rc1 can help limit power consumption by current processors by allowing them to idle for longer periods.
