Silicon wafers would have a similar problem: enough energy to blast dust would probably damage the wafer. E=MCsquared would damage everything nearby. John

Thanks for the correction. Got a bad relation in my head. Maybe it is the ratio of explosive mass, to the amount that actually "goes missing". http://en.wikipedia.org/wiki/TNT_equivalent#Examples .... 2kg equates to 42.96 Mt, or 1 Mt = 21.48 gm (if Wikipedia is to be believed.) And the other's point about the OP meaning chip manufacturing vs. the chips from machining a block of material is well taken. The equivalent "hand grenade" explosion of converting a dust mote to energy, somehow avoiding destroying the chip circuitry and its various photo processes, will still be unworkable. David A. Smith |
