Focus Fusion

I got an e-mail a few days ago from Aaron Blake at Focus Fusion, alerting me to their website and their proposed Focus Fusion reactor, which to me looks like just another inertial confinement fusion system. Of these, we know that unless they are very, very efficient at keeping the plasma contained, they will never approach breakeven, this thanks to Todd Rider's MIT graduate thesis. Moreover, their hydrogen-boron fusion appears to have a conflict with Bremsstrahlung radiation losses, inevitable energy losses that are inherent in the choice of fuel.

A distinct lack of scholarly footnotes, parenthetical rejections by the DOE, and the prominence of fundraising on their website leads to immediate questions as to the true nature of the endeavor; are they trying to build a reactor, or are they trying to fleece the public? Hyperbolic press releases add to my concerns.
