I saw the title of this thread and immediately thought of this guy lol

The hardest part of backyard engineering is building something that works with the parts you have available!

Something to consider... Instead of chains, belts, and gears; how about this:
Fit a rubber strip to the outside of the flywheel. Then get a child's bicycle wheel and attach it to the generator shaft (or another type of wheel with a rubber tire). Fabricate a bracket for the generator so that the wheel is in contact with the rubber strip on the flywheel under tension.

It might not be the "most efficient" setup, but it will do the job for pennies.

To help with visualizing the concept, look into how trommel drive systems are often constructed using motor vehicle tires.

I only just found this thread so this is possibly too late...

Did you run some math regarding thermal uptake of the water mass vs thermal loss of the greenhouse? It usually works out that you can't efficiently transfer enough heat from a hot greenhouse to the water during the day to completely offset the thermal loss by the greenhouse at night. Remember that not all days are cloudless...

What happens is that the system "runs down" to equilibrium over about a week or so. Here is a video explaining what goes on:

Oh I forgot. .. Pears. My worms just can't get enough of pears.

invasive usually means that it grows fast in the environment. Since your soil is so terrible, why not put these immigrants to work building organic matter in the soil using a regular chop and drop regime?

To increase your current delivery, you need to reduce the internal resistance of the battery somehow. Either by using different materials, or constructing the cell so there is less distance between the plates.

To increase the battery charge capacity, you need larger plates so they can store more charge. You can achieve this by increasing the cell size, or make another cell like the original and connect it in parallel.

My thoughts exactly. Why waste all that effort taking perfectly good soil, damaging the microbiome, and mixing it with the subsoil?

Sure, you have the makings of a hard pan because of how clay behaves, but digging in your topsoil will simply move the hard pan deeper. I think your better off continuing to lay down organic matter. Rolls of baled hay for example, and put your worms to work for you.

This is not such an easy black and white subject in my opinion. The term "organic" has been co-opted by big ag for some time now, and many of the organically certified chemicals used in industrial organic farming are just as icky as the synthetic stuff.

If I were you, I would make a clear distinction in my intro with regards to which "organic" my essay is actually talking about.

It's neat stuff for sure. But do you have any practical applications for it where it would be the best choice of materials?
From what I understand, it doesn't work well under load so as a construction material it has limited applications.

I've been thinking of a application for this stuff where there isn't a ready and superior material and haven't yet come up with anything.
