That thing is hot mate, good job!!!
2 old138on 03 Feb 2010 at 07:37
Good idea. I wonder if you could use it on a lake up north to keep the cool side cool.

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

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

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.

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

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?

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

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?
10 GREENPOWERSCIENCEon 03 Feb 2010 at 11:42
We are making some that will do the trick, just a little more time:-)
11 sodia1on 03 Feb 2010 at 12:34
i need one of those to power up my pc do you know where i can buye a 100 wat one ?

it is great idea to make the pump as a water pump in remote areas to harvest solar enery without having electricity.
13 indiasrainbowon 03 Feb 2010 at 14:12
looks great
14 ycats1000on 03 Feb 2010 at 15:04
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-

search “Concentratore solare da parabola satellitare” an experiment of italian student in 2006.
16 GREENPOWERSCIENCEon 03 Feb 2010 at 15:29
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.

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.
18 Fastlan3on 03 Feb 2010 at 16:30
Why don’t you use the extra heat to run another stirling engine, or would that not absorb enough heat?
19 GREENPOWERSCIENCEon 03 Feb 2010 at 17:03
This Stirling engine concept, no. It is about 3-5 watts at best. The engine is a nice design, but the dish is too small and needs a better mirror.
20 jatpack3on 03 Feb 2010 at 17:37
verry interesting,but dose it do anything besides make noise,any practical applications?
21 GREENPOWERSCIENCEon 03 Feb 2010 at 18:23
Hi,
The 24″ dish came from a supplier, I can see if they still have them. I will post if they come it. These are industrially turned aluminium.
22 prefermetalon 03 Feb 2010 at 18:25
Where did you get your parabolic dishes from ( 24″) You make them from the glass template and cut them with the table saw?
23 tbfl72on 03 Feb 2010 at 18:50
where can i find a seterling engine?
24 GREENPOWERSCIENCEon 03 Feb 2010 at 19:43
buy more solar panels.
25 GREENPOWERSCIENCEon 03 Feb 2010 at 19:46
Agreed on solar. I got a 9 watt panel with no load voltage reading 21v to jump up to 33v with a Fresnel lens. I placed a plastic bag filled with water on the backside to absorb the heat. Also…. Mirror arrays work better with less heat. New high temp panels work better. Because solar cells have very thin wire, a little heat increases resistance and limits the flow. If you can take cells, apply a heat sink to each, and apply better connectors, you can handle more heat. WOULD be cheaper to just..
