My latest project. Recently I designed a new generation wind turbine. I am going to miniaturize my design and work it into the front trunk area of a teener. My goal is to drive coast to coast non-stop........ Ambitious? Yes! Doable? Yes! I will accept any help thrown my way! (IMG:style_emoticons/default/drunk.gif) By the way, it is great to be back here, I missed this place! |

Dead down wind faster than the wind DDWFTTW It works, see the videos Barefoot http://www.youtube.com/watch?v=aJpdWHFqHm0 |

Dead down wind faster than the wind DDWFTTW It works, see the videos Barefoot http://www.youtube.com/watch?v=aJpdWHFqHm0 The difference here is that (I think) the original poster expects to use the relative difference between the vehicle speed and ambient air speed (termed here as "wind") to power his vertical wind turbine which is in-turn expected to power the vehicle. Since this "wind" is actually generated by the vehicle itself there is no energy to harness that is coming from outside of the vehicle's energy system - hence the 'perpetual motion' designation. At best the original poster may be able to recoup some of the energy used to propel the car when he wishes to slow down in a form very similar to regenerative braking, but second law losses will severely limit exactly how much of that is recouped. If it is being used to capture energy from actual wind (e.g. energy in the atmosphere) then certainly this is no perpetual motion device...but as was alluded to before there simply isn't enough there to capture to reach his goal of a cross country trek, even if he had a constant headwind the entire way! Same goes with solar power (PV). There simply isn't a high enough energy density of solar radiation to power a car of this nature - especially given the pathetic efficiency of PV panels. All that said welcome back to the site 1jwalters and good luck with your project. We all need hobbies! (IMG:style_emoticons/default/bye1.gif) |

Because some "law" ....."says" something..... Listen guys - I am not going to pass the gravy here! (IMG:style_emoticons/default/biggrin.gif) What I am doing would be considered "outside of the box." So when you guys start citing "laws of thermodynamics this, and laws of perpetual motion that" you are all way, way wrong.......on a total other planet even.. But the REAL skinny is I am really not doing anything groundbreaking - I am just the one who was able to see the forest through the trees is all (IMG:style_emoticons/default/beerchug.gif) All too many times people get bogged down with "data" and that alone is a stumbling block. When I have a question to something I do not "google" it...I research it... You nay sayers are going to be sooooo upended when you discover my method of accomplishment it will be talked about for years to come....... Glad to be back home, like I said before, it is as if I have never left! For over 5 years that is......
