Is the beverage dispenser tube situated in the cleavage so one has to plunge his face between his girlfriend's breasts to retrieve it?
What they should have designed is a bra that captures the heat generated by the human body and the motion from walking and general movement to generate electricity (similar to how they generate electricity on hiking backpacks). Although I would like to see girls walking around in bras all over the place (and solar panels would make it lovingly geeky), I doubt it'll be commonplace.
For most of us geeks, something capturing body movement would generate about a 1WH a day during trips to the bathroom, snack machine, and car. Its why I had to trade in the riding lawnmower for a walk-behind.
