The Kontax KS80 solar acrylic Low temperature Stirling Engine is mechanically identical to our KS90 range of engines, but with a couple of money saving cosmetic changes. These changes can most obviously be seen in the different spokes material and in the absence of the seven brass chamber pillars around the main chamber.

THIS KS80 ACRYLIC ENGINE WILL PERFORM THE SAME AS OUR KS90 ACRYLIC ENGINE

Yet to have the KS80, but, it is going to come here to live on and on and on. My former KS90, I ran for a full year, then gave it to a close friend. The KS80 will have the same build quality (faultless), and I will photograph it coming out of it nesting-parts box, and video the simple assembly, and show it running under various conditions, and keep it under the glass accessory dome, and it will run for the rest of my life, and then some. Will be "writing" = posting to YT, a comprehensive review of the KS80. It will be good. There is no superior LTD engine-type on the market; nothing any better than a genuine Kontax model of any model type or number.
