Fusion reactor development has long interested me. From what little I know, Tri Alpha is unique in that they plan to fuse boron and won't use their reactor as a glorified steam boiler.
By fusing boron I believe they avoid producing neutrons. The downside is it requires higher temperatures than fusing only hydrogen and the energy output is lower. However, avoiding neutrons has a strong economic argument in that neutrons degrade the reactor.
I'm a touch hazy as to how they generate electricity, but have to figure bypassing a boiler and turbines is a good thing.
Am I right in my analysis? Are there others following the similar routes?
I've read of other efforts, notably Lockheed. Unfortunately, Lockheed seems to be rather closed about information. Are there other interesting developments?
