Metal skinned 'valves'

Uh, didn't some of the big AM transmitter 'valves' have metal rather than glass shells ? IIRC, they were water-cooled, could be disassembled for maintenance, then pumped down again. Similar tech was used for mercury-arc rectifiers, no ? Seems unfair to mention that no documented WB or Polywell has y...

Fascinating !!

Uh, that's well within the range of 'active optics' mirror flexing. Of course, shifting X-rays one mm is only a start. Still, it reminds me of the glancing-incidence 'optics' of early X-ray telescopes. The workings resembled a skeletal Fresnel lens or circular Venetian blind, with the focussing done...

Slightly OT: Skylon's Sabre engines.

Reaction Engine's Sabre design is air-breathing to high Mach, transitioning from jet through combined jet/rocket to pure rocket. Their design should manage this using a remarkably efficient heat exchanger to chill air-flow.

This may integrate nicely with a polywell-driven electric jet system...

Elegant...

Just the thing for a hands-off installation such as a Moon or Mars base, or an interplanetary 'ferry'. FWIW, it would do nicely as the 'boot' supply for an isolated WB site...

Quantum entanglement...

IIRC, the estimated speed for entangled photons' interaction over several kilometres' separation currently stands at ~ 10^6 c. How such entanglement applies to still-hypothetical gravitons, I don't have the math. I must speculate that any correlation has a very-near-unity probability of collapsing o...

Cosmic rays and OT: Aerogel

Are cosmic rays likely to present a problem ? Especially if HV collection is used, there seems to be a risk of flash-over... OT: Uh, given 'free' heat, cold and vacuum, there's a possibility of making a raft of balloons full of aerogel on-orbit to soak up the low-flying sub-cm impactors... Free-flyi...

Mach effect vs Mach principle vs Mach conjecture...

Is this related to the 'enclosed thruster' proposed a year or two back ? Where the energy density in a *closed*, tapered waveguide theoretically causes thrust ? I remember the uproar, and reading that the math comes down to a Y/N result depending on arcane, ambiguous interpretations of the physics. ...

A question of size...

"It stretches the bounds of physics to imagine one powering anything on a roadway. " Remove the roadway, and the power levels would suit a monster drag-line or similar excavator. Okay, they'll still need that kV power-cord, but it beats trailling pylons to the back of where-ever... Fusion powered op...

Skylon by modules, or Heavy Lift.

Uh, as I see it, you must arrange to assemble eg Skylon-shipped Polywell modules in shirt-sleeve environment, vent, bake then retreat to safe distance and light up. Alternative is a one-shot ride on super-heavy lift rocket that the Big_Ob wants NASA to build... Pure coincidence, of course, of course...

How do electron microscopes manage ?? == OT: I remember having *great* fun adding a simple thermocouple to the shelf of a modest vac oven. In the end, I had to re-arrange the plumbing to pass a metre-plus 1/16" probe through the cross-bar of a T on the pump line. The final step, from 1/4" to 1/16", ...
