Self rotating LTD solar heat engine

Hey guys!

I wondered how viable a rotary heat engine with solar energy only.
The temperature different maximum 3 degrees at the moment what this engine use.
But the engine is working only 1 degrees too!
I was suprised in this afternoon when the sun is goes away from the sunflower engine, but that is works well, but slowly. It was a big suprise!
Outside was hot, so the solution was the radiant heat across the window glass what the engine is absorbed and the room was the "cold" side actually. 
Outside temperature was 38 degrees, the room temperature was 35. 
The engine arms moves slowly and somethimes I measured only 
0.8 degrees different between the sides!!!



Also works with angle.
I made a mimic plastic flower at 45 degrees.


And the full shadded one is a pretty unique:

New DIY tutorial step by step video for a Solar LTD Puskás teeter heat engine

Hi guys,

I have received a lot of feedback via e-mail:

"How do you build it?"
"I need one, send me the parameters please!"
"Cool! Where is the tutorial video Blade?"

I finished with it last night, so the video is arrived!
Share this instructional video with your friends!

That is the primary help what you can do for me!

LTD Puskás heat engine

Hi folks,
here is my new type 
Puskás teeter heat engine!

This is a real LTD heat engine, because the engine works with low temperature different!
The engine start at 3-5 degrees different!
My engine's working range is 27-31 C

The key of the operation is a heat sensitive material.
This material is pretty sensitive for heat.
If we have a curved one then after heated up that material will straight or even concave.

This is a salted peanuts bag's material.
Aluminium base coated with plastic.

The original Puskás water engine is here:

And the Hungarian blog:

This engine use moisture for an expansion/contraction effect in paper material.
The paper base is cellulose what really sensitive for humidity.
If we can moisturising one side only than the paper fold in a curve.
The engine was my friend Simi112's (YT name) invention in 2006!
It works with water only.
Pretty suggestive little engine for tabletop.

My version is a real heat engine actually.

When the plastic material heated then 
the sheet from a curved shape goes to the straight
pretty fast!
After when it's cooled down then curved back as originally was.
So the teeter can unbalanced with it too! 
:)

Let's build one! :)
So easy to make!
This is a solar engine too, but it was a cloudy day in Hungary.
I used only a cup of hot water as "sun"!

If the heat different enough to make the unbalancer curves
then the heat engine start freely!

If the shadow, or clouds coming, 
than the engine stop and hold on the start position.
So cool! 
:)


And the real SOLAR LTD version works in sunrise:
