It is a very old thread and the forum was transfered to a new server at some time, possibly more than once. Some attachments were lost in the transition I think

The thread, with images was preserved on the internet Archive though.

I'm not sure, can a PDF be uploaded here?

Apparently not.

There is a download link to a PDF I came across about the engine on this site:

THANKYOU Tom!! wow what a machine, Sounds like it was a rush build, despite the significant Darpa backing.
Pity some images are hard to interpret..
But the pdf helped with the cross-section drawing & certainly helped with graph axis readability.
I dunno why but engineers seem obsessed with the axis terms being as tiny as possible!
Any idea what it sold for?
I'd love to buy a 5-6 kW unit. I see Danfoss has taken over UQM Tech. pity, Danfoss aint cheap.
The only snag here is the price of natural gas here, Oz is being raped of our resources. Everyone else gains the benefits, except us!

So would a lot of people, including me.

There was only one archived page of the auction that I could find.

It appears it was not sold. The only bid of $10,000 did not meet the reserve.

wow!! wasn't expecting that.. anyway it would be out of my grasp, sadly, esp considering all freight etc.
Thanks anyway. Being back in 2013 maybe it got sold via another method..
