You are right, this is a pretty stupid idea, but kind of fun. Even if screws were used which were at least as sharp as standard crampon spikes, the walking-on-the-ceiling trick would always be crazy. As for power, well you would need probably three cordless drills per boot -and currently-available battery technology would allow a two hour climb on ice, maybe. “risk and reliability analysis” are you kidding ;) ?
