    In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. The switched-mode power supply's higher electrical efficiency is an important advantage. Switched-mode power supplies can also be substantially smaller and lighter than a linear supply because the transformer can be much smaller.

  7. Carbotanium - Wikipedia

    en.wikipedia.org/wiki/Carbotanium

    The components of carbotanium; carbon fiber and titanium, are woven together to form a strong, light material that can withstand significant amounts of heat and strain. This is because carbon fiber has the highest strength-to-density ratio of any current fiber and titanium has the highest strength-to-density ratio of any current metal.

    It also featured a front-mounted slot-loading optical drive. [3] The notebook was given the unofficial nickname "TiBook", after the titanium case and the PowerBook brand name; [2] it was sold alongside the cheaper iBook. The 1 GHz version of the titanium G4 is the last, and fastest, PowerBook that can natively run Mac OS 9 (version 9.2.2).
