... [eddie currents are ] a very very elegant solution for a lot of reasons but the problem is cost in magnets and copper...
So, I couldn't just superglue $20 worth of pennies and the magnets off the fridge? Well shoot... I do like the idea of detaching the cable to do a safe emergency descent if you're otherwise stuck. You could have one of those detach pulls like you see on garage door openers to manually open the garage door. ;-) |
She'd probably be sensitive about that. Preferably we could figure out something to reduce the amount of freefall.At least it is only a 6 or 7 foot drop when it fails.
As for the magnet... how about an electro-magnet? Not sure how you'd reliably automatically trigger it during an unintended descent (a mechanical acceleration switch?) so it would be fail-safe (brakes generally work the other way, that is the break is on when there's no current).
