What is "12V (ONLY)"?
That is as simple as it gets.
Charge the battery.
Use the power.
Nothing more to talk about. It is so simple it is not worth mentioning.
Might look deeper at 12VDC vs 120VAC CFLs.
Quite a few talks about what is better, and why.
I do small solar. Miro Solar by the standards set here.
Most solar I install is 12V only, except for items needing more than 12V.
And I mentioneted it a lot.
My solar users can not morally use a solar powered cordless drill, if the drill has an 18V battery?
An 18V drill battery charger needs an inverter, or a degree in electrickery.
Pests larger than 0.224" have a simple solution. .22 is what we called it back before the term PC.
OB intends to tax .22 to the point of using chemicals.
Merigolds.
Recycle.
Use a bicycle.
Ever eat corn? Might want to look into the moral implications of that one.
If you believe NOT painting your items is less toxic than:
mining new iron (timbering), processing, manufacturing, shipping, painting, packaging (peanuts/styrofoam/cardboard/colored ink/), re-shipping, re-re-shipping, retailing, etc,
then just buy new stuff.
Recycle again.
Charge a 12V battery and use 12V loads.
Remember what is involved in the entire 12V battery thing. Lead processing facilities, huge weights transported long distances, acid, Mexico /Rio Grande and fish with 19 eyes?
Do you understand how a 12V solar panel charges a battery?
Do you understand how a 12V load uses the 12V battery power?
That is all there is to a 12V system. Charge. Use. Simple.
If you do not understand it there is nothing anyone can do.
Where does your "poo" go?
Seems like it should be recycled into something (fertilizer?).
I expect it is sealed in a giant rubber bag lined land fill.
Who wants to eat food fertilized with your poo?
Landfills are expensive. I have an idea most 'poo' is still sent down the river.
About 30 years ago I had solid proof. Easy to obtain. Nobody cares. It gotta go somewhere.
Funny, but selling super-processed poo makes big bucks.
They still burry it at a high cost.
You make methane. Everyone does.
What do you do with your surplus methane?
Or is your methane something that happens and there is nothing that can be done about it?
