non-electric ceiling fan???


hey guys! Non-electric fan is really a great idea! Imagine how much energy would be saved if everyone is using that. Hopefully you find one, and please don't forget to share it with us. Thanks!

I have seen what you are looking for. It called a Nordic Ware Oven Aire. It is meant to be used to turn any oven into a convection oven but that is what you are trying to accomplish.

Did anyone in this thread ever build one of these? I have been thinking of how to accomplish this off and on for a few years, but haven't gotten around to doing it yet.

Some cars use power steering fluid and the pump to operate a hydraulic motor instead of electric motor for radiator fans. You can use a diesel engine to run a hydraulic pump and use glycol based fluid to operate hydraulic motors.

Or, you can use a fuel powered air compressor to run air motors

non-electric ceiling fan???


This is the last time I will bump this thread. I've received a half-dozen different e-mails in the last couple of weeks asking what I've found and if I know anyone who has ever made one of these fans and that is why I am doing this. There has been a lot of useful comment and information passed around since I began this thread, and one or two false starts, but no fan. I want to thank everyone who participated and encourage you and anyone to post new information or experiments that you have done.

I am continuing to work on the puzzle of moving heat downwards but I am likely going to change direction as to the method to be used. If I create a good, working piece of equipment I'll share it with everyone.

Thanks.

Hi all,

I found this site while searching for a non-electric ceiling fan I saw on ABC yesterday. It doesn't seem that the inventor has them in production yet, but thought I'd at least share the link to the show since there are so many others here that are interested. Hopefully she'll get these on the market sooner or later.

The fan segment starts around 26:00

Does anyone know if there's been any progress from the dicussions on previous pages?

Please recheck your link. It is only 4 minutes long and doesn't point to the segment about the fan. Am interested if you can link it up here. Thanks.

Sorry about that, lets try again! This should be from the beginning of the show... a PITA to fastforward through because you get stuck with commercials but it should be there at 26:00.

non-electric ceiling fan???


Hi Bobrok,

I was not able to read all the postings so can not say if some else has already suggested what I would like to suggest here. If you want to push out the hot air gently you can use what was known in the old Persian world as Baadgir or as Malqaf in the old Arab world. It is basically a long vertical shaft that provide the hot air a channel to rise and accelerate upwards. It consequently creates suction drawing more air up the chimney. I can also additionally use the wind to create more suction. This would of course be bulky but is a real long term solution as it has no moving parts. This system can still be found in countries like Morocco and is the basic ventilation and cooling method used in many natural systems such as the colonies or ants or bees.

The structure built by the ants is incredible. Fifth link down from the top, if anyone else wants to see it. They poured 10 tons of cement in to fill it up! Very cool to see when it's completely uncovered.

Thanks for the link tiderider.

non-electric ceiling fan???


I could see a windmill type source of power, with the pump rod hooked to a bicycle pedal assembly, which would then turn a shaft with a pulley on it and provide the propulsion for the belts system.

There is a restaurant in Rockport, TX, where the 10 or so ceiling fans are all powered by what looks like a long loop of rope, but the propulsion is by electric motor. I like the idea of a 12-volt motor, powered by solar PV panels...but I could see there might not be enough power to keep it going in a blizzard when the need to circulate heat is greatest.

Good project....if not a standard "fan" type windmill (which would present some problems b/c the wind would swivel the tail around and that might well prove a problem for the attachment to the bicycle pedal arms), better yet a sort of vertical axis squirrel-cage fan. That way no matter which direction the wind was blowing from the fan's frame could be fixed and the problem with attachment to the crank assembly would be solved...or, better yet, eliminated--if the axis of the pulley's shaft were vertical the pulley could function to drive the belt/rope system without need for a pedal crank assembly . Still haven't figured out how to waterproof such a system...I visualize it as roof mounted, but it could be mounted to a porch and the belt/rope system protected from rain....can't be too difficult, can it?

I think the fan assembly from an old "Swamp cooler" type air-conditioner would work if it could be coupled to a large fan assembly, would just require a decent source of moving air to provide the power.

Cheers!

Dugly

Agreed, that is amazing to look at!

This conversation may already be closed but I was also looking for a spring-driven fan to go in my off-grid cabin. I found several old patents from the early 1900s by googling spring motor fan. There are pictures and descriptions. Thought this might be of some help to someone who's mechanically inclined.

If anyone has any idea of how to build a non-electric fan I would be very interested. I'm just going to start experimenting. Maybe try to adapt a victrola/phonograph spring motor. Maybe build some kind of grand-father clock mechanism. www.veproject1.com has some ideas about using gravity or magnetism, but I'm not sure these would be strong enough to create much of an air flow. Springs or weights seem the best way to go.

Found a spring powered bike here: http://www.clockworkmotorcycle.org/
