The Martin Fleischmann Memorial Project announced a new replication approach by Alan Goldwater:
*GlowStick* 5.4 AKA *GlowShell* undergoing initial calibration tests...
Looks like it may be able to reach target temperatures with half the input power of previous *GlowStick*
Alan Goldwater adds "The enclosures are made from whole kiln bricks,
which were easy to cut and drill with ordinary hand tools. I measured
around 60 °C on the tops with 400 watts input, so they insulate really
well."
