Interesting selection. A couple of them jump out at me...

Guardian Angels - there are two advanced concepts here: the guardian angel idea and the energy-scavenging concept. Both are fascinating and have great potential to change society.

IT Future of Medicine - I was actually talking to someone about this the other day; about how modern medicine is still such a game of hit or miss / sense and respond. It seems to me that a well-programmed computer, armed with a full set of diagnostic data could make a very individualized diagnosis. What I don't like is the emphasis on drugs, rather than holistic/homeopathic considerations.

But I think I'm leaning toward RoboCom, especially if they can make one that looks like Olivia Munn. But seriously...
