Thank you all so much for the input.  I have a great deal to mull over now and work on over the winter in my shop.  

Fantastic input.  Thank you Willam.  I will start exploring those options

I am looking for some help in locating something that I can repurpose.   I have been working on building a wood fired hot tub.  I have a coil of copper around a rocket stove and it is working but it is not very efficient.  I spent 2 weeks using a "Kelly Kettle" on a wilderness expedition and I am not convinced that this would be a better solution to heating the water.  I basically need a double walled chamber with an intake and outflow for the chimney.  I am looking for ideas for something I can find in a scrap yard or somewhere that would work like this but so far I am coming up blank.  I thought I would reach out to the brilliant minds on Permies for some thoughts and direction before I look into getting it custom fabricated.  

Thank you for your time.

Thanks for the input.  Pump prices I am seeing are in the 100's of dollar range not 1000's but you are probably thinking of the panels and other parts. I have that stuff lined up already cheap and cheerful.  As per what I am going to dredge out is just sediment and muck.  When I walk in the pond there is a couple of feet of just much from decomposed plant material. I think the muck has blocked the natural springs in the pond. If I get the springs opened up again I do not have to worry about the aerator.  The plants I am worried about are cattails.  They have really started to take off in the last few years and I do not want to loose the pond to them.

As the snow begins to disappear I am full of ideas for projects, but as always I have run into roadblocks due to my limited experience.  I have found several direct solar aerators online but I got reading that you can use a regular water pump and turn it into a venturi pump which will give you oxygen as well as a current.  My pond is 2 acres but only 6 feet deep.  I have a guy welding up a dredge to clean out half of it but I want to keep the weeds down and hopefully make it more prolific with fish. I need some help with figuring out what type of pump I need for this project or would it be a matter of a few of them? I am assuming a continuous use pump is ideal but I am lost with sizing.  Any help or direction to good resources are appreciated.

Thanks Phil.  I figured as much.  I may still tinker with it.

I have been kicking this idea around for awhile now and I am hitting a wall with it and I figured I would tap into the expertise on this forum.  On our property we have a 2 acre pond about 300 feet down an embankment from out house, beside a river.  The regulations in Ontario make it extremely difficult to use the river to produce hydro power.  The river has a high flow rate but not much head.  I have yet to find a run of river system that is available to purchase.  Lots of interesting prototypes out there but I digress. I have been playing with solar panels as of late and I am in the design phase of a pond aeration system and I got thinking I could use solar to pump water up the hill, fill a pile of those 1000 litre water cubes then let the water run out when the sun was not out to make power?

Any thoughts and input welcome.  This may just end up in the pile of other energy producing ideas I have tinkered with over the years and come to nothing.

Thank you for your time and consideration.

Thank you so much everyone for your input.  I will try to rig a ceiling fan and get back to you.

Looking for a little advice/help with heating a Geodesic dome. I work at an outdoor based school, where the kids spend the majority of time outside.  As winter sets in they spend more time inside.  Their classroom space is a membrane covered geodesic dome with a layer of insulation under that. It is build on an insulated platform.  There is a large wood stove in the dome but it is still not heating up well.  .  For some reason the solar air exchange fan is located almost directly above the wood stove, which I am assuming is removing the heat as fast as the wood stove makes it, but it can unfortunately not be moved.  My current strategy is to put those thermocouple fans on the wood stove to circulate the air before it goes out the vent.  This has helped some but the dome does not get near as warm as I would think it should with a wood stove that size. Any other thoughts or input would be welcome.
