Abstracts (patent-holder's characterization): - US 5,502,354: "A cold cathode vacuum discharge tube is used in a circuit for generating pulsed autoelectronic emissions ... in the abnormal glow discharge region, and involve much lower current densities than predicted by the Fowler-Nordheim vacuum arc discharge region law"; electrodes "preferably spaced at least 2 cm apart". [web] - US 5,416,391: DC power transducer; the PAGD tube "capacitatively coupled to an external load including an alternating current device, typically an electric motor". [web] This is the motor-driving configuration that matches Mallove's "output motor power (mechanical shaft power)". - US 5,449,989: "double ported circuit": a DC drive pack at the input port and a "current sink in the form of an electrical energy storage" (charge pack) at the output port "captures at least a substantial proportion of energy released by collapse of the emission pulses". [web]
Numbers in US 5,449,989 (patent holders' own data) - bears on claim 1
- Method: 12 V, 6 Ah lead-acid gel cells (Sonnenschein A212/6S) as "drive packs" (input) and "charge packs" (output); power measured "videographically during a 10 second period"; output/input expressed as "percent breakeven efficiency" (breakeven = 100%). [web]
- Reported values include 228%, 230%, 289%, 310%, 388%/391% ("surplus factor of 3.9x"; 0.962 kWh gained vs 0.246 kWh lost over 18 minutes), 483%, 485.2% +/- 18% (n = 64; 48.3 Wh drive loss vs 221.7 Wh charge gain), 563%, and 906% (run 8, 32 pulses per second vs 5 PPS). One configuration with a squirrel-cage induction motor registered 96% (below breakeven). [web]
- The patent itself notes that the batteries' "grossly diminished (50-60% of manufacturer's theoretical estimate) effective charge capacity" can distort values "by up to 10 fold ... particularly at the extremes of operation". [web] (Relevant to the reviewers: battery-charge accounting is the measurement basis of the patent figures.)
- These are 1992-1995 figures (roughly 2x-9x), in a different configuration (battery to battery) from Mallove's 2001 figure (DC input to motor shaft power, ~10x).
