STIRLING ENGINE SOLAR POWER PARABOLIC MIRROR ELECTRIC GENERATOR

GREENPOWERSCIENCE asked:


http://www.greenpowerscience.com/SHOPHOME.html This is a larger Stirling engine that has a 12v DC Permanent Magnet motor operating fixed as the flywheel bearing. It produces 15 Volt max with NO LOAD. This setup as is produces about 15 watts. The heat sink is a water cooled tank that is a bit short for the displacement piston but does work. I will be adding some heat sinks soon and testing it with the 56 inch dish and a Fresnel Lens. The motor/generator has an additional pulley that the other …

Scale is the issue with these things! It's GREAT that you got it to work, but scaling it up to a usable, productive level is where you're going to run into issues. You aren't the FIRST to propose this, and nor will you be the last.

Absolutely fantastic! An excellent prototype for small-scale future power that can be produced with more readily available materials (metal vs silicon)!

I see you have a 56 inch dish, and it produces 15 watts… perhaps with 2 cylinders it would produce greater and more even torque to drive the motor.

If you don't mind my asking, how much electric can be generated by a conventional solar panel of comparable size to this set up?

Video effect explanation. You shoot video of an area without you in it. Then you shoot another video with you in that area. The camera should be in the same spot (mounted on tripod) for both shots. Then using video editing software you slowly transition from the first video to the second. Very basic video editing stuff I believe windows xp's movie maker is capable of doing this.

Hi I would be interessted in how much amps this produce by any chance…

I device to follow the sun is fairly easy to make. Since it only has to move slowly, a small electric motor geared way way down is enough to do the moving.

The electrical circuit can be based on just two photodetectors on either side of a small vane. When the vane points straight at the sun, the two see the same light.

Do you have access to electronic parts?

Your welcome, just walked in the house from making more chemtrail videos. They just turned what would have been a very pretty sunrise into garbage. Take lots of flaxseed/oil, from what i read it helps purge the aluminum from the brain tissue.

aluminum. that makes sense. helps block transmission of signals in the brain and leads to Alzheimer's in severe cases. thank you.

Would you sell me that engine for $800? If so send me a note.

Hi,

You need a heliostat or just a timed motor. Check Ebay for telescope tripods, some can track. Or watch this video.

hi dan
i´m all the way down in brazil
i was planning in doing a college project using a parabolic miror, but my physic´s teacher told me that in order to be effective it must follow the sun!!!!!
could you please give an update on that
of corse i´ll give you and the greenpowerscience the credits
thanks a lot for your attention

IM DOING MY SCHOOL PROJECT ON THIS INSANE HUGE MAGNIFYING GLASS!!!!
AHHHHH!!!
FROM CANADA!!!!! AHHHHHHH!!!
ok, see ya

oh that's fantastic! I don't suppose you have any links to start me off with?

Yes, there is, they are more compact and lighter. The free piston engines designed to be very efficient and lightweight use these type of alternators. NASA has a bunch of information on these, and Sunpower and Infinia both make these type of engines. Check out mowerofdoom's videos…he has an engine with one…actually there are a number of videos with linear alternators.

What do you think of setting up a fresnel lens and some mirrors to melt salt, which could then continue to power the engine when the sun wasn't out?

I do not know if it would do more that power some small LEDs but it is a good idea. The design is tricky as is, I think it would be a tough task. Do you have the videos code so I can find them on Youtube. I have seen them too, just cannot find them. Thank you for the great message.

Dan, I've seen a couple of stirling engines on youtube where the reciprocating piston has been attached to the flywheel of a rotary permanent magnet alternator on it. Steam pistons too. I'm wondering if there would be any point to using a reciprocating magnetic generator, like in the "shake flashlights" that were sold on tv a while ago. The whole apparatus would be one big piston moving back and forth, no mechanical change.
Also, love the fading in and out, makes you look magical and stuff.

I would love to do a solar power system here in Indiana but we get creamed almost everyday by the chemtrails, very few sunny days here anymore. Going to be a bad yer for crops, no bee's, no sun, lots of aluminum in the soil.

I will have a full video soon. I just have to get the DIY one to work good:-)

Would this be something for which you'd share design plans?

Awesome vids, as usual. I esp like the fade in and out on this one. Is that a trick from your new camera?

Hi Dan, Stirling is exciting, esp with Fresnel or large Parabolic. Enjoy your vids. What size Stirling can you get, and can it still turn under load?
