sergiy yurko solar thermal concentrator

For some months I have been watching interesting YouTube videos from сергей юрко of Ukraine who, over the last two years, has built an impressively sized (58 sq. m of mirrors) east-west oriented concentrating solar trough heater.

Sergiy uses the array to provide heat for a home in winter and a swimming pool in summer in Mirgorod, Poltava region, Ukraine, about 50N latitude. In this video, he provides an English explanation of his steam demonstration.

In this video from about a year ago, he gives an overview. His previous videos are in Russian.

He uses strips of salvaged glass mirror attached to a clever stationary frame. Note the simple locking height adjusters that allow tilting the frame to match the seasons without using motorized tracking.

I was surprised and pleased to see his English videos as Sergiy Yurko. This is new. Sergiy is still adding to his Russian videos like this one from a week ago.

Note that he shows my work in his intro at 0:09-0:11!

Thanks for your interest.

I have recently been interested in your blog posts about the trough concentrator of Sergiy Yurko. I too am the inventor or new trough solar concentrators. I would also like to contact Sergiy to ask him some questions about his system. I don't know how to contact someone thru their YouTube posts. If you will answer me you can contact me at
Thank you,
