With respect to the video, I watched it once and the message isn't clear. Is this a project about greywater reclamation or about a better greenhouse? Or, as a commentator mentioned above, are you just looking for approval to run the kickstarter?
From what I've seen in the threads, there's a lot of interest in this kickstarter. I'm not sure you need further approval to run it.
If it's both greywater management and greenhouse design, my sense is that it took too long to articulate a simple problem (greywater management) and didn't give enough attention to the proposed solution (an Oehler-style greenhouse). I'd like to hear more about the reasons an Oehler greenhouse deserves attention from Wheaton labs at this point (it's nice that you like experimenting, but it would be more interesting to compare the Oehler-style greenhouse with other models), what directions you're going in for design improvements (longer than a quick mention, anyway), who might be involved in conducting the experiment, and what outcomes you anticipate at this time.
If the project is more about developing and improving Oehler's design for an earth-sheltered greenhouse, why are you introducing it with the greywater issue? It will be useful enough just to have a good greenhouse design that, for me, you don't need to introduce the project as a solution to a problem with greywater management. I'd still like to hear more about those four areas I mentioned in the last sentence of the paragraph above.
If the project is about greywater management, maybe it would be helpful to touch on a wider range of solutions, including but not limited to the Oehler-style greenhouse.
If I need to watch the video more than once to understand your project and the 'ask', I don't think it's an effective video. Sorry.
