It is very cool.
While he's possibly the first to think of it in a photography context, I have heard of an ice lens being recommended in a survival context -- fashion a lens to start a fire with the sun.
I've had no idea if it is actually practical; I'm sure you'd need some very good dry & fluffy tinder. This photo experiment tilts it much further into the 'Plausible' zone.
