"The initial energy stored within the capacitor bank is typically in the range of 3,500 - 6,300 Joules (watt-seconds). Because this energy is discharged in approximately 20 millionths of a second, the instantaneous power is very large and, for a brief instant, is roughly equivalent to the electrical power consumed by a good sized city. The repulsion forces between the work coil and the coin create tremendous radial compressive forces that easily overcome the yield strength of the metal alloys in the coin, causing the coin to plastically deform into a smaller diameter. The higher the initial energy, the greater the degree of "shrinkage". Applying a 6,300 joule pulse results in a quarter whose final diameter is about 0.1" SMALLER than a dime! At the same time, similar radial expansion forces cause the work coil to explode in a potentially lethal shower of copper fragments."

I have one of these quarters at home.

His capacitor banks are huge! This 6100J power pack for photographic strobes (http://www.bron.ch/bc_pd_p...) is less than 35lbs. What's the difference? Is this guy just using higher voltage?
