  1. Micromanufacturing for Energy Efficiency 70% reduction in hard disk’s dimension leads to 75% reduction in energy required to operate it. [Seagate] Array Microchannel (107 microchannels) 3’x3’x24” 300 µm thickness 200 µm wide channels Example: Micro-channel heat exchangers have demonstrated heat fluxes 3 to 5 times higher than conventional heat exchangers [Paul 2005] IMPACT Energy storage Energy efficiency Energy generation

  2. Specific challenge • Energy efficiency, energy storage and energy generation • Idea for meeting the challenge • Attack the problem at the micro-level while the accumulated effect is at the macro-level • Approach • Innovative micro-manufacturing technologies for high volume production • What is the manufacturing challenge? • Fabricate millions of thin stocks with thousands of microchannels or micro-features within a few microns accuracy • Perfect bounding of those thin stocks • High temperature and high pressure applications
