Summary

Paul Wheaton and Jennifer Richardson talk about the kickstarter for the truly passive wofati greenhouse that will process greywater from Allerton Abbey all year round, even through a Montana winter.

The greenhouse needs to keep plants active through the winter in an area where they normally go dormant so that they can process the greywater from the Abbey. The design is being developed from Mike Oelher's earth-sheltered solar greenhouse with extra ideas added to produce a greenhouse that never freezes even if it's left alone for five years. This will be a truly passive greenhouse that uses zero electricity - not even a fan!

Paul answers the following questions to help people understand what it's all about.

1. What will people get if they support your kickstarter?

2. Why are you offering so much stuff for people who are only supporting your kickstarter at the one dollar level?

3. This seems really different from your previous kickstarters. All your other kickstarters were for projects that were almost complete but you haven't even started building this one yet. Why the change?

4. How exactly is this greenhouse different from other greenhouses?

5. You're saying 'truly passive'. which implies that other greenhouses which say they are passive really aren't. Is that correct?

6. What does success look like for this experiment? How are you going to measure the results?

7. Assuming that this experiment is a success, what does that mean for the world?  

8. Why should someone give YOU their hard-earned cash versus all the other people and organisations out there?

9. Assuming that this kickstarter does well, do you think you will do kickstarters for other experiments in the future?  

10. How would somebody be able to participate in one of these experiments?

Just curious: why do you consider an automatic vent opener a non-passive technology, since they don't need any energy input?

While they operate passively, they also require maintenance and, sometimes, replacement in my experience.  
Had 'em on a 28'x8' greenhouse in a previous place, 2 on roof vents and one on a louvre vent in the wall.  After a few years they all gave different problems that had to be sorted out.  
If they fail to open when they should, it can get too hot and kill your plants, if they jam open somehow then it can get too cold in the night.

I suspect these reasons are why Paul is keen to avoid them.  I'm interested to see if the de-stratification system works, as that has pretty much nothing to go wrong with it.

This.  Exactly this.
 
The only cure for that is hours of television radiation. And this tiny ad:
