Perhaps someone with a high speed camera can tell me, how long it would take for say a 26 inch bandsaw upper wheel to fall enough to kill the blade tension. I feel that breaking the blade physically is much faster than trying to drop a bandsaw wheel down (not to mention this may damage the saw).
As for the actual breaking of the blade itself, not sure if a powered guillotine will be fast enough... But if it could be made small enough, perhaps one can be placed above and below both guides, so the blade is broken in two places.
May be more useful for larger bandsaws as used in sawmills.
