A new preprint from Arxiv.org -
"Super Dielectric Materials"
http://arxiv.org/ftp/arxiv/papers/1403/1403.6862.pdf
- proposes new "super dielectric" materials with dielectric constants 10,000 larger than the best known dielectrics.
The authors note that -
"it is interesting to speculate on the potential value of NPS (New Paradigm Super) capacitors ... leads to a remarkable energy density of ~1000 J/cm^3. A D-battery (flashlight battery) has a volume of ~53 cm^3...a one D-cell sized NPScapacitor could hold 25,000 J."
Dielectric breakdown currents have been theorized to initiate LENRs. For example, see Brian Ahern's patent --
"Amplification of energetic reactions" WO 2011123338 A1 - at URL: https://www.google.com/patents/WO2011123338A1
Patent item [0024] notes: "Discharges through a dielectric embedded with metallic particles behave very differently. The nanoparticles act as a series of short circuit elements that confine the breakdown currents to very, very small internal discharge pathways."
If the dielectric materials described in the Arxiv preprint are real, the dielectric breakdown currents may be immense.
