A Windmill Powered Car Travelling Directly into the Wind

- This is my 3rd version of a remote control windmill powered car to see how fast I could 'sail' directly into the wind. This video was taken with a dying breeze blowing 5-10 kts. The car is designed to go fastest straight into the wind, and although no measurements yet, it moves upwind at jogging, or maybe running speed. My radar gun is useless here because it just picks up the turbine blades.
Steering is remote controlled, as is the rotation of the mast mounted turbine. This makes driving the device a bit of a challenge until you get used to it.
two sets of miter gears take the power down through the mast to a horizontal axle, which is chain driven to the drive axle.
that is verry interesting
it looks nice
If you can find a way to feather the prop. I think you can improve your net ground speed. Just something to ponder. Excellant model.
free-wheeling........no controls? have you also done a DDWFTTW (faster than wind) version?
he did say that, didn't he? Obviously, you can, but the downside is that speed doesn't scale up with size. I've considered building one large enough to hold a person, but it is a real technical challenge to get it going into the wind faster than the wind itself.
thats trick, good job.
Caricature1997: Sorry, I'm no help right now. It's my own experimental design, and I don't have a design package put together yet. I'm still contemplating improvements.

And Mitt Romney says you can't run a car with a windmill on it!
I'd done some thinking about the vertical windmill and it seems to me that it's power for a given 'sweep area' would have to be substantially lower than that for a Horizontal Axis Wind Turbine (HAWT). Do you know of evidence otherwise?
madinventor13:
Analysis I've done to date indicates that I should be trying to get the maximum energy out of the turbine regardless of the force pushing back on the turbine, hence the relatively 'flat' pitch of the blades. - Do you have experience or theory indicating that increased pitch (feathering) helps?
can i buy a smaller version of this?
How did you make the lower gearbox? Can't see from the video.
Berkhan Bayraktar a vertical bevel gear transitions to a horizontal bevel gear which is on an intermediate axis parallel to the drive wheel axis. There is then a reduction chain drive going to the drive axis itself.
Leonard Vance I understand, I'm doing a similar project but still didn't decide how to make lower gears.
