In a nutshell: Penrose (and others) believe (or used to believe) that gravity can cause spontaneous wavefunction collapse, basically something simpler than decoherence. The "speed" at which this collapse occurs should be dependent on the mass of said object; the "characteristic speed" of consciousness, on the order of 0.1 seconds, would be generated by sub-cellular sized structures and which he links to structures called microtubules within neurons. You'd have to read his books if you want any of those details filling in.

If you read other people's comments you will quickly see why, although this is a Good Thing prima facie, it does have worrying implications that need to be addressed (e.g. the storing of "secret" URLs).
