Yesterday I had contact with Alan Goldwater ( magicsound
) about the Glowstick 5.2 tests.
In this thread, we can discuss the experiment. Alan Goldwater will be available for discussion/feedback.
URL for the live stream will come here as soon as the test begins.
Glowstick 5.2 - Preliminary
I'm preparing for the next series of Glowstick tests (described below), to hopefully begin this weekend.
I've made some design changes for GS5.2 to deal with problems noted during disassembly of GS5.1:
* The gap between the capsules has been increased to 1" (2.5 cm) and the heater coil will be spread accordingly at the center.
* The center spacer will be made of alumina felt, tightly packed. This will hopefully allow passage of hydrogen while restricting the flow of liquid metal across the gap.
* Filler rods of SS316 have been added to the plumbing, to reduce the dead volume for more accurate measurement of pressure during loading. This will also retain the inner filler rod in place on that side.
Pre-treatment of Ni powder will be done in a furnace by thermal cycling in air at 200C. Next will be some tests of Hydrogen loading, using only Ni powder. This will establish the time/temp profile needed for the next run with Rossi-patent fuel.
