The sharp, thin memory alloy pick is pressed through the cork, keeping it above the surface of the wine. At the push of a button, the tip heats up causing it to bend sideways. Pull out the cork.-- FarmerJohn, Jun 03 2005 The competition. http://froogle.goog...&tab=ff&oi=froogler [daseva, Jun 03 2005] Yeah, cause I was getting really sick of those "rabbit" corkscrews.-- daseva, Jun 03 2005 How does the tip get heated?-- bristolz, Jun 03 2005 Much like a soldering iron, I'd imagine.-- justaguy, Jun 03 2005 Would that work?-- bristolz, Jun 03 2005 Resistive heating of nitinol, for instance, causes it to shrink in linear dimension by 5-10%. I'm not so sure that it can be made to "bend sideways" with enough strength to pull a cork. Might require a hinged tip of (for instance) stainless steel, actuated sideways by the nitinol.
Thin strips of Nitinol have resistances on the order of a few Ohms, suitable to create a few Watts from a few Volts (i.e. AA batteries.) This should be able to create a 40-50 degree C temperature rise, and suitable shrinkage.-- csea, Jun 03 2005 random, halfbakery
