=russian patent in Spain...


=very promissing construction !
I don't trust them.
This graph is from their site:


It's a straight copy of this graph from Lorenz ECDrive, with a new line added:



So they are claiming 98% efficiency from 2% to 120% load, comparing it to a 1-6 hp motor, without any details of what power rating, or how they get such astonishing results.

Colour me suspicious.

The patent

I believe they are close to a machine that takes advantage of the "action/reaction" principles, a little compressed air technology and we might see the first "thermal-electric power unit"
That patent reads as more gobbledygook than science.

I'll try reading it again tonight, but it says nothing about how this invention is supposed to work so much better than existing e-machines.

I knew what it meant, but looked it up anyway :)

Where did the word gobbledygook come from?
What exactly is gobbledygook, and where does the word come from? Texas Congressman Maury Maverick coined the word in 1944 to describe the frustrating jargon used by policymakers in Washington. It reminded him of the sound of turkeys gobbling.Dec 29, 2012
