parabolic trough concentrator -PART 1 PARABOLIC TROUGH Satellite Dish Conversion Concentrator Catenary Chain Parabola

February 19, 2012 – 6:29 pm

Www.youtube.com ** This is Part 1 This is the intro in a row a large satellite dish and find the correct form for a parabolic mirror. When the video dish is ready. I have a link. It ’s very close :-) It works great. The form with a rope or string is not a true parable, it is actually a catenary shape. This is quite close to our solar projects and infrastructure projects. In the next video, I will have full step by step by step process for building the mirror. THE PARABLE EXCEL DOCUMENT CAN BE FOUND ON OUR WEB SITE FOR FREE www.greenpowerscience.com :-)

  2. I really like those paintings at about 6:18

  4. someone just tell me where we could buy that sheet? and tell me some info about material for that sheet

  5. Rain-X Defogger Liquid is used on glass to stop fogging. the water just runs off and keeps glass clear. might be worth checking it out ? i used some of another brand on my dads old sports car and even in the winter the glass stayed clear without a heater, amazing stuff.

  6. OOOOOPS Im back and thanks for the comment to keep me on my toes. the ends of the elipse are just close.
    It takes an infinite distance of one screw to make the difference. elipses are just close.

  7. Thanks for the comment. I have went back and restudied this and found that if you make one of the foci at infinity the minor end of the elipse is parablic..
    Otherwise if the the 2 points are close it is just an elipse with two ends that are close to a parabolic curve.

  8. Also, a paraboloid is not a parabola. I feel like we’re arguing different things. :< But basically a parabola is only a section of an ellipse if the foci are infinitely separated. There is an elliptical paraboloid which is a quadratic surface and looks like a cup.

  9. Im not perfect but I will double check this and get back to you. Thanks for keeping me on my toes. I always thank those that correct me.

  10. No. An ellipse is not two parabolas stuck together.

    By WillBlocher on Feb 19, 2012

  11. THE ENDS OF THE ELIPTICAL SHAPE ARE PERFECT PARABOLOIDS.

  12. Can’t you also use a compass to draw the parabolic shape? It would also allow you to predetermine your focal length.

    By taofledermaus on Feb 19, 2012

  13. That is only true if the distance between the focii is infinity and you would be able to cut it anywhere. But in practical terms it is impossible.

    By Mhyque on Feb 19, 2012

  14. Cut an ellipsis in half and you get 2 parabolas.

  15. Yep:-)

  16. being that i come from a very humid area myself i can attest that a dehumidafire is a lot more effective then an ac. its not so much that he has an ac that gets me its that he brings it up yeah its just for a brief sec but hes a partner so he is making money off these videos about being green so if your going to make money about being green then put off an image that your actually being green use a hand saw here and there you know what i mean

  17. i think he kinda has to…or else he would wake up soaked

  18. hold on did you say you came out of your air conditioned house thats mighty green of you

    By delbomb3131 on Feb 20, 2012

  19. That’s for an elliptical shape, which is closed. A parabolic should be open I believe.

  20. lol @ comments

  21. Change the distance between the screws to change the focal point. the paraboloid is at the ends of the oval shape.

  22. I love the centenary definition. there is an even easier way to get a perfect paraboloid with out using all of the quadratic formulas and all that technical data. You were close with the chain and nails.
    1. Put 2 nails in a board at a reasonable length.
    2. cut a string more than twice the distance of the screws. tie the ends together. place it around the screws and place a pencil inside the loop. then move the pencil in a circular motion with the string as a guide. MUDDY

  23. You’re not exactly, “sexy:”.

    Thing about the it.

  24. I promise you, if you get your wife on the video’s saying the same thing that your doing.. you’ll get a lot of youtube money.

    By warforlips on Feb 20, 2012

  25. i would also like to know where i could pick up some of that material as well

    By ironbord on Feb 20, 2012

  26. Hehe! Dan, your editing is getting so much better. Looking forward to the rest of the project!
