Back during the 70's crisis I attended a talk by several energy
inventors, one of whom planned to seal solar collector pipes into
uncoated fluorescent light bulbs and then evacuate them. It might be
worth pursuing if you rolled or welded a bellows section into the pipe
to absorb expansion. Personally I'd use rubber seals and a small
vacuum pump so I could disassemble the tubes if necessary, or compare
the performance of argon and CO2. Like everything else I do that's
fine for experimenting but doesn't make a practical product.

When I learned chemical glassblowing we used platinum wires for glass-
metal seals. I know from trying it that iron seals into light bulb
glass but I didn't have the means to experiment with the leakage

Well, the frequencies would be a problem if you are trying to supply
directly but if you are simply using it to charge batteries then I don't
think it's much of a problem.

THANK YOU!!! I've seen that idea before in an internal combustion
application, but it completely slipped my mind on this.

Now I've got fun toys to play with... :-)

 My notion of the idea came from one of NASA's Stirling motors. I
goofed round with the idea of using round magnets with plastic washers
sandwiched between (serving as rings) as a "free piston" bouncing back
and forth in a long aluminum cylinder (pipe or tube) wound with wire
(coils) and functioning as a "resonant machine" to generate
electricity (linear generator).

The whole thing was intended to run on steam and had three moving
parts the magnetic piston/ring, pressure valve, and switch (or bounce)
valve. Seemed like something at the time, until material designing a
magnet to withstand steam heat.

Like some other stuff I may want to re-visit this idea again, after I
get settled in with some proven low tech solutions (wind, passive
solar, bio-fuels).

Have fun.

Maybe not for your battery charging, don't know about the neighbors TV
or radio reception. 8Q
