Aster Thermoacoustics
Interesting work on both thermoacoustic heat sources and matched bidirectional turbines for electrical power generation. Thermoacoustic electrical generators previously used linear alternators, but those prefer faster cycles, which is opposite what the thermoacoustic wants (parts sizing goes up unfavorably when scaling), and slower long stroke linear alternators also have issues (long piston stroke, sealing issues). Using a rectifying bidirectional turbine may be a convenient workaround.

Laser cooling of solids: latest achievements and prospects
> The main technique of laser cooling of RE doped solids based on anti-Stokes fluorescence is presented in this paper. The new approach to optical refrigeration based on the Raman cooling is also considered. It is shown that the future prospects of the research are connected with laser cooling of μm- and nm-sized samples, are in their applications in biophysics in the fundamental studies of low-temperature physics.

Buttoning Up The Lama's Head | BimmerLife
After I submitted last week’s piece describing reassembling and reinstalling the Lama’s head, I thought that I might have the bloody thing running in one more repair session, perhaps even by the end of that very day. This estimate, of course, turned out to be optimistic. via Pocket
