Something like this would do the job with a small solar panel. Just hook it up with dryer hose.

The whirlybirds work by letting the rising warm air spin the blades. I wonder if putting the intake lower in the solarium and the whirlybird highest in the cold house would do the same? The house being colder would be like the outside? Or does the whirlybird need a breeze blowing by to get it started?

Cool, ( or heat ) That has me thinking the right way, could even build something using one of the R refrigerants that boil much lower temps? I have solar there but don't want to waste power on that if I can do some kind of passive pump. We eventually will have about 7K watts more solar there but this is just to take advantage of the situation this winter to keep the house side from freezing up so hard. This place has basically been abandoned for 10 years... On 11/04/2020 10:14 AM, ch...@wbmfg.com wrote: > Heat Pipe. It would work a little. Finned tubes from a radiator.
