[NewCandle] Energy Harvesting

[Nick Reiter]

Ja,ja...

Our chum from the Tech of Earth, Scott, played with it
a bit in about 2000 or so, and felt that my particular
design was not so much a Casimir generator as I had
hoped, but something between a charge mill and an AC
or reversing field Wimshurst machine.

The true variable cap effect continues to intrigue me,
and I typically had thought in terms of very large
multi-plate air variables.  So much so that about 5
years ago, I got some quotes from an air variable cap
maker in Indiana on making a jumbo canned unit for me
that by my crude calculations would have delivered
about 100W, but alas would be about the size of a beer
keg and have set me back about $20K.  Now maybe one
could combine motions ala Horace's design of approach
and slide to make the output less sinusoidal and more
impulsive...

The Holy Grail 'neath ancient Roslin waits.
The blade and chalice guarding o'er Her gates. 
Adorned in the masters' loving art, She lies;
She rests at last beneath the starry skies.
