  1. Update on results at Coolescence, LLC Rick Cantwell Coolescence, LLC Boulder, CO rick@coolescence.com +1 720-565-9690 October 2008

  2. Coolescence, LLC • Founded in 2005, Angel funded, 3 researchers • Areas of experiments • Calorimetry • Glow Discharge initiated LENR Built on work of Karabut & Energetics October 2008

  3. Calorimeter for GD Experiment • Flow Calorimeter surrounding vacuum chamber (320 cm3) • Cathode Pt RTD allows Isoperibolic operation • Built-in Joule Heater October 2008

  4. Calorimeter Engineering • Dual In/Out temp measurement (thermistor) • 2 stage fluid temp regulation (+/-5 mDegC) • Air temp regulation (+/- 50 mDegC) October 2008

  5. Daul Calorimeter Block Diagram October 2008

  6. Calorimeter Performance • Flow Calorimeter • Sensitivity: 20mW • Capture Ratio: 90-94% • Time constant: 19 minutes • Isoperibolic Calorimeter • Sensitivity: 5mW • Time constant: 5 minutes • Sensitive to pressure, heat location October 2008

  7. Typical Performance October 2008

  8. Glow Discharge Loading of Pd • Initial focus on Glow Discharge initiated LENR using calorimetry to find anomalous heat • No excess heat results • Characterize deuterium loading with Glow Discharge October 2008

  9. Apparatus & Techniques • .3 & 1.5 liter chambers • Glow in 1-10 torr D2 • Pd foils (25-100 micron) attached with diffusion weld • Pd & Pd alloy thin films (1-5 micron) on copper • Loading measured by gas loss (pressure drop) • Verify by pressure rise during unloading • Capacitive Manometers October 2008

  10. Major Loading Observations • No high loading (D/Pd < .7) • No bulk loading at higher temperatures • Loading rate proportional to current (J<100mA/cm2) • 5-10 D’s loaded for each D+ of ion current (Faradaic Efficiency 5-10) • High D flux during pulsed discharge (.01 sccm/cm2 per mA of glow) • Loading rate insensitive to temperature, voltage, and pressure • GD causes damage to Pd (sputtering) October 2008

  11. Loading Efficiency vs. D/Pd October 2008

  12. Pulsed Glow Discharge October 2008

  13. Loading vs. Glow Current October 2008

  14. Loading Rate & Temperature Loading vs Temp Sample 40 12 10 8 6 Faradaic Efficiency 4 2 0 0 20 40 60 80 100 120 140 160 Temp 2.5 mA 10 mA 25 mA 50 mA 5ma October 2008

  15. Physical Effects of GD October 2008

  16. Questions raised by GD loading results • What is mechanism of loading? • What limits loading to D/Pd ~ .7? • Are common mechanisms at work in GD (Karabut, Savvitamova, Energetics, …), gas flow (Li) and gas flow transmutation (Iwamura)? • Was high loading present in earlier GD and gas flow experiments?
