how to model a bioethanol plant?
For a School Project, we have to design an applaince to produce bioethanol from gras. Some ideas?
To extract ethanol you typically use a still. I doubt raw grass will contain any significant levels of ethanol, you must ferment it in order to create ethanol. I have a model of a still if you want it let me know but it is a far cry from any kind of production facility.
I believe grass is not a very good plant for fermenting, even cows need 4 stomachs to digest grass. (and even than cow shit is still full of undigested grass)
You need a plant that has a lot of sugar onboard such as sugarcane.
Also plain potatoes will do the job
