1. these small stirling engines put out almost no power they are useless
   for anything practical.Just toys.

2. Free energy technology exists!But the Establishment doesn’t want ppl to know this,Find this technology at LT-MAGNET-MOTORdotCOM ,Start the revolution!

3. This is got to be the best solar dish stirling arrangement. To me this is the design that is worth putting money on upscaling.

4. I do not understand why these demo engines never have a tracking system on them? The engine makes plenty of electricity to power a small tracker and gear.

   Put a solar collector near it to power the tracker so that it will move into position automatically every day at sun up…. or add a battery with a trickle charge to power the tracker…. Both would probably be best…

5. Thats cool. Can it actually do any work? Can it turn a generator?

6. It’s all just smoke and mirrors… Da-dum chhhhh haha. Very cool stuff actually, makes me want to get into fresnel lenses again. :-)

7. I invented a breakthrough renewable source of energy that violates the law of energy conservation. I have a proof that there are phenomena that violate the law of energy conservation. I am looking for $6M for a prototype and patents.

8. That thing is hot mate, good job!!!

9. Good idea. I wonder if you could use it on a lake up north to keep the cool side cool.

10. I guess they should put solar cells in the center of the parabolic mirror for effective energy gathering that can obsolete the use of solar panels :P

11. 19KW you sure that’s accurate? average home with computers and ac and fridges only uses 5-10kw.

12. How much power can be produced from a parabolic mirror with the stirling engine concept? I’m wondering what it would take to power my home which uses an average of 19kw/day with about a 4.92 insolation value.

13. wow, the lid to my fire pit is dish-shaped and 27 inches. ima make copies of it

14. I need a stirling engine for larger applications(. I am trying to convert a 10 foot C-band into a heliostat using mylar. Will you please point me in the right direction as to where I can get one?

15. We have one really close for sale on our website under more info, “Buy a Big Fresnel Lens link will take you there.

16. I need to either make or buy one that is at most 12 inches in diameter and has a focal length of less than 12 inches. Where can I get one? Or what would be the best approach?

17. We are making some that will do the trick, just a little more time:-)

18. i need one of those to power up my pc do you know where i can buye a 100 wat one ?

19. it is great idea to make the pump as a water pump in remote areas to harvest solar enery without having electricity.

20. looks great

21. laminar flow ones are simple, people tend to over complicate things with weird mechanical linkages to suit alternators

    but you can get linear alternators, that way you may only need a few magnets on the shaft… lets you use the high speed as asset and not force the engine into trying to create torque which it cant handle-

22. search “Concentratore solare da parabola satellitare” an experiment of italian student in 2006.

23. Yes and no. A simple one is easy, one with power is a lot more difficult. I will have a video in the future making one. This one was purchased. For your project, consider a Simple Lamina Flow Engine.

24. Is it hard to make these solar-powered stirling engines. It’s just that for next year, my thesis is about them, and I have to make one of my own.

25. Why don’t you use the extra heat to run another stirling engine, or would that not absorb enough heat?
