Use a coil *around* the building. This makes the problem just within the realm of the possible, though horribly impractical.

I'll spare the collected minds and spool spaces of the technomads list the details, and reduce this to a recipe:

Collect the following:

- 20 miles of 0000-guage insulated copper wire (about 32 tons worth) - five standard 20 MW gas-turbine power plant generators (about 20 tons ea.) - fuel for about 10 minutes of operation (about 4 tons) - five standard high voltage transmission rectifier modules for the above. - one standard 69,000 volt, 10,000 amp transmission-line contactor set

Wrap 1000 turns of the wire around your target. This makes a bundle about 18 inches in diameter. Wire your generators and rectifiers to yield 70,000 volts DC, and connect them via the contactor to the coil.

Suppose, however, the goal was NOT to erase the media, but simply to reset (temporarily crash) the computers inside. Please recalculate based on: 1. A 72,000 volt, 0.8 microfarad capacitor, fully charged. 2. One turn of, say, #16 wire around the building. 3. A (sacrificial) improvised switch constructed by forcing a sharpened point through a thin, insulating layer of polyethylene plastic sheet against a conductive plate, which eventually (and catastrophically) arcs through the remaining fraction of a millimeter to produce an exceedingly low-impedance contact in a microsecond or so. -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBMQWb3/qHVDBboB2dAQF0YgP+M8pc9nYzp0fwBblcd6TNC3kDt88NZbpy WiyeCxfW8tx8KNgniERKMIRrCFXfciUew9Bs1orX3CdJeDgUG2ByiLoSbGcco3Jm Vtw4MIVhhyITOhF2ocZBsReutm5WonnZlj+0upxgzYOwC0NyXR5jtHmsUMksa9Sq jy0mW2rdLxw= =1GMF -----END PGP SIGNATURE-----
