Solar Power Fan Update

As many of you are aware, we have installed, and are testing an inflator fan which is run totally by solar power. We would like to eliminate or reduce the amount of variables and unknowns before we make this package available. One of the big questions has to do with how many days the little fan can run the way it is supposed to on consecutive cloudy days. During the aftermath of Hurricane Patricia we experienced numerous cloudy days in a row with the temperature just above freezing.

There is not enough margin for leeway in this package so we are checking out a smaller fan. If this works, then this would be the way to go for the smaller greenhouses. Our greenhouse has about 500 sq.ft. of double cover which is not all that big. This would also confirm that we need either need a bigger storage battery or a second solar panel.

Please stay tuned for more updates.

Center pivoting gable vent

We are pleased to introduce our center pivoting gable vent as a simple solution to the challenges of venting a building. For venting to be effective, it has to be as high as possible. This is a cost effective alternative to costly roof vents.

Part of the window swings in and part of it goes out. Because of this, rain is never an issue and the window is easy to control even in extreme winds. Incoming air is always deflected up to mix with the warmest air. The tubular steel construction makes it both lightweight and resist twisting over time.

A continuous rope goes from the top of the window to a pulley at the ridge, down to ground level and back up to another pulley and then to the bottom of the window. By tying the rope off to an eye bolt on a gable post, this allows for very simple control from ground level.
