Hi Bjorn,

Thanks for the story.
I do not think the type of the tunnel diode is so important. And a transistor curve tracer should still be available in different labs to see the forward current/voltage characteristics of the tunnel diode on display and read the forward voltage range needed for the negative resistance region. 
The main problem is further lack of probably crucial details. It is obvious the inventor did not reveal how he got the power from the circuit to melt metals: tunnel diodes work with max some hundred mV forward voltage and some mA (10-50mA or similar) of forward current. It is even possible that there are missing parts he did not include in the patent. Is the inventor still alive?

Thanks again,

Gyula

Wow, Google is fantastic!

I found this while searching for "olof wallen":
http://www.spi.se/presskl.asp?pg=6&AktID=1892
dated 2006-01-30 means he should still be alive.

For those of you not speaking swedish, the gist is that Wall?n warns for the dangers of an explosion while fueling ethanol due to build-up of static electricity.
"Jan-Olof Wallen and his company Walnostat Marketing are in the business of removing static discharge"

Not to post any direct information here about companies, you can 'search' for yourself:

If you DO manage to find something out, don't forget to post it here at overunity forum!
And at least try to fid out where he buys tunnel diodes!   
Good luck!

hi there , I cant tell you where to buy tunnel diodes, but somewhere, i saw an article on how to make your own. this could be better still , aswith practice you could make one with whatever characteristics you want. I beleive it was on Bill Beatty Wierd Science website . could anyone finding it please post a link.
