I am a very infrequent commenter on HN. I have one page, total, of comments since I signed up. Two of those comments give a reasonable run-down on MSR technology, if you're interested.

The "die hard" MSR guy in the US is Kirk Sorensen of Flibe (Flih bee) energy: flibe-energy.com He's easy to find from a Google search, and is incredibly dedicated to MSR. He's the evangelist, for sure.

Bram Cohen of BitTorrent fame is on Flibe's advisory board.
