  1. Lower Energy Computer System -- Operation System running on USB Flash drive Ian

  2. Feasibility Study Business Problem: • Now the modern computer consume a lot of energy. Desk top computer usually are 300w – 400w, even more. • But in a emergency condition, we need limited power to support as long as possible to make the computer even the internet work. • .

  3. Feasibility Study Current Situation: • A desktop (or laptop) computer with the ability to boot from USB flash drive.

  4. Feasibility Study Approach Overview: One way is to running system from USB flash drive, it works same to RAM, it can save 10% power than running OS from hard disk. When read data from hard disk, it normally use 15% power of total, and RAM only 5%.

  5. Feasibility Study Potential Solutions: • Boot windows xp Operation System from USB flash drive. • Boot linux Operation System from USB flash drive.

  6. Windows VS Linux ---power consumption

  7. Windows VS Linux

  8. Hard drive VS USB flash drive • Hard drive power consumption round 10watts, depend on capacity and brand. when it is start is consume more power than idle time, up to 30 watts. • Flash drive using is a special Ram, power consumption under 1 watts.

  9. Cost Estimate - USB Flash Drive with bootable function. 4-8GMB price: $100 - Operation system that will install on USB: • Windows XP professional • Office work on USB • Linux operation system (Ubuntu 7.10) price :$500

  10. Sketch

  11. Installation and Test • Windows XP Instruction: install windows in USB trail 5 Result: fail • Linux OS (UBUNTU 7.10) Instruction: install UBUNTU desktop version 7.10 in USB Result: pass
