Nearly everything is part of multiple systems.  Many of them overlap and most have both positive and negative feedback loops present.  Only things that are dependent on truly randomness can be outside a system and even most of those are parts of some system.

One other bio source would be cattails because they are not normally grazed.
suggestion to try would be apple sauce.(have never tried with pancakes or waffles but should)  For cakes you can replace the volume of oil with the same volume of apple sauce.  The cake is mildly moister and slightly denser feeling in your mouth but have never had it fail to look, feel and taste like a cake.

If you don't need huge amounts suggest looking in your local highway right of ways.  In our area one of the things the reclamation crews have been planting along the highways is a really tall bunch grass.
Comment #1.  I would not go with a 12V system simply because so many of the direct drive things need at least 24 volt system.  The more things you can directly drive without an inverter the lower your overall cost and the greater your efficiency.

#2  Be very careful doing your homework mppt systems.  A review about 18 months ago tested something like 40 different ones that claimed it and nearly all of the cheap and mid levels systems were simple pwm systems in spite of the claims for being mppt.

#3 in my thinking I have been looking at recharge cycle life expectancy and because battery life is based on number of cycles I have been looking at super capacitor banks as my primary daily use one since if they are kept cool they can have a half million cycle life expectancy.   Way lower power density so a battery bank is still needed but should reduce the number of cycles needed.  Problem is needing a charge controller designed to balance all factors.  Hadn't found one yet.

This year's experiement #1 is with very early spring sown daikon radishes.  I actually germinated them indoors in a paper towel in early to mid april and then planted the seed that grew as small bare root plants at just past the first true leaf size.  Created little mulch pockets around each one a tiny bit of shelter with total sunlight.  Took a bit of frost damage to edges of leaves but didn't seem to kill any.  The reason for doing spring sowing is because supposedly when it gets hot they will bolt so hopefully I can grow seeds with the spring sowing with the intention to only harvest seed while leaving the radish undisturbed to rot and build soil,  Will see how it works.  The other thing growing in this location is the Bocking 4 comfrey.   The hope is I can build deep soil in this location combining both of these and at the bottom edge the plug/dam that holds the water in this area is a long term compost pile.

#2  I have a micro dutch clover that I am hoping I can harvest seed from when it matures.  It was too pricey to do at the scale I want to do it.  The beginning goal is to plant a patch to simply be a seed source into the future.  Will see how that goes.  Still  need to get the biochar inocculated for this area and then get it worked in.

I have and will put both patches at gutter downspout outlets in hopes that I can get them to no care mostly.  The goal is to create patches of ground that really hold water and produce the seed for my other projects.

I am no where near self sufficiency but hopefully moving that way.

In a general answer I am going to say probably not for the average engine.  Combustion energy and flame front speed would need to match diesel and that would be tough to do reliably for the fuel as those change from batch to batch.    And you want no conversion time making it tougher still.  Most engine systems I am aware of doing dual fuel need a warm up time on diesel before converting and on the other end they have to  run on diesel for a while to flush the other fuel out of the injection system before shut down.  With care you can probably make it work but expect higher emissions and lower fuel efficiency and a lot of time adjusting your fuel mixture for each batch

Now is bio diesel on your possibles?  By processing it chemically you end up with a more consistent fuel.  In warm climates possible but in cold climates will still need warm up and cool down change over cycles or heaters in fuel system.

Now there are a few engines out there that are designed for dual fuel operation.  I know VW had one about 15 or 20 years ago that the electronics changed fuel delivery timing and injector pulse length so most fuel could be used.  Still needed heaters or system flush runs to change over from fuel that might be gelling cool.  Betting there are other specific engines available if you research

Is the picture eggs or larva?  Looks like eggs to me.  Soap or oil treatments likely best answer.  Is it leaf bud or blossom bud? is the other question I suppose should be asked.  Often eggs on the surface of a blossom lead to a borer who will end up inside with the fruit so if this year matters needs to be fought before they get inside
You are getting air in some place.  Is it stopping when you are in a low flow mode or when you are running at max flow.  Sounds like max flow.  So most likely it is sucking down to within 4 or 5 inches of the top of your pipe at the head end, then creating a whirlpool vortex that sucks air from the surface.  A good siphon with lots of flow will eat a tiny amount of air steady state by mixing it with the downstream water and dragging the bubbles out the bottom end but it takes very little to disrupt this by getting too much air in, creating a bubble and stopping the flow.

Now they do sometimes put what amounts to a chamber on the top at the highest point that will trap some bubbles but its capacity is very limited.  Now if you have a lot of flow on the downhill side there can be a line running a ways down the hill inside the main pipe.  The main pipe does a mild constriction and the line runs just past it creating a vacuum that pulls air out of the chamber.  The chamber is often used for priming large systems.  Turn the valve off at the bottom end and suck air out of the chamber till the pipe is full.  Since the chamber is the highest point in the system that is where the air collects.  Seal the chamber off, open the valve slowly and the siphon is off and running even in really big pipes.

But sucking air at the inlet will disrupt the best siphons no matter what you use.  One thing I had minor luck with was a piece of window screen floated above my inlet pipe where I couldn't get it deep enough.  Put a flat board there and the vortex just craws along it till it can snake its way to the surface.  But the window screen sort of grinds the vortex up so it doesn't reach the edge.  Was only partially effective but seemed to help a little under the right conditions.  It is critical though that you do not pull too much water and expose your suction pipe.

Now guessing the discussion of an air valve there is either a suction port or and air admittance valve to prevent suction or cavitation damage while draining a big line.

In my home growing up the measurements for making ice cream topping include a glub,(not glug) of corn syrup.

Seasoning things included a dash(2 good shakes roughly) and a mite(might?)(about 2 to 3 dashes).

Adding grain to an animals feed included a bit.(roughly 2 handfuls with hands held together)
