Excellent explanation. I understood a complicated subject and I can see that this system is a really useful way to work out the issues of all the hoopla over cow farts destroying the ozone layer along with gas cars. Seriously, living in semi rural NC it’s a cool system and I get how it works. It reminds me of how the chicken farmers use chicken poop slurry to spread on the fields in early spring (my favorite spring day because it totally messes with all the city folks who have moved here for the country ambiance but don’t expect real farm life to happen and interfere with their pristine idealism!)
