What did I miss?
Also... That the radiator is there for the purpose of keeping the
tube temperature within an acceptable operating range. In a
self-powered unit, the direct conversion of internal heat energy
will be taken off inside the tube itself, using the 3.4 eV photon,
which can happen either by UV photocell or by a multipactor grid,
or by several other possible but more complicated ways - but the
operating range of the tube itself still needs to be kept steady
and within a certain regime.
Getting the thing to self-power, which is NOT the intent with this
particular experiment is all about 'where and how' the 500 watts
of excess heat in going to be converted into electricity, in order
to be recirculated and self-power.
IOW if you have ~500 watts of excess heat from ~200 watts of
electrical input and the tube needs to be maintained at 300 K then
you must convert and remove the internal heat at greater than 40%
and then still take off whatever is needed to keep the tube cool..
UV photocells are not to that efficiency level AFAIK, however the
Miley direct-converter, mentioned a few days ago, can do this at
upwards to 70% efficiency, but it is much more complicated.
I do not have a clue as to how Moller is going to pull off the 40%
conversion, but I suggested many months ago a version of the
traveling-wave gyrotron, which is essentially what Miley has
concocted. Moller may have other tricks up his sleeve, or he may
be waiting on funds to continue the process. I do not know the
current status of this - so let us be clear that much of my
optimism is based on educated-speculation based solely upon what
can be done (in a perfect world) and should money not be a huge
impediment to progress, which it usually is....
Often, however, financing is not the problem for those with
offices in Berkeley Square, London and Labs in Switzerland. I wish
Moller well. Time will tell - I am only presenting the best
scenario which comes to mind, but any realist should temper this
level of optimism with "l'loi de emmerdment maximum."
