Additionally it sounds like they are planning on using some energy to maintain the heat in the wire:
"Heat would continue to be supplied to the operational wire periodically but not constantly in order for it to maintain its heated state and keep the chain guide in position. The system would be operated by "an electric current generator installable in a pedal crankset of the bicycle"
Although I imagine they could get around this with some sort of toggle spring mechanism to hold it in place.
