First up, I'm new here, so go easy on me! I stumbled across your site when doing some follow up research after looking for ways to get rid of a huge pile of leaves!
Anyway, I'm keen to go down the whole "off the grid" path and am looking at aqua phonics etc.
My question here involves energy production. I was wondering if anyone could offer some advice.
It seems to me that there are three ways to "consume" the fuel. You can burn it directly (I plan a rocket-stove design), you can digest it to produce methane or you can gasify it to produce another flammable gas (hydrogen?)
I'm looking to use a combination of kitchen scraps, garden waste, wood-workshop waste and possibly human and animal waste as my fuels, but which methods should I use for each in order to get maximum energy?
For example, the leaves and / or grass clippings. Am I better digesting them to get methane, or turning them into pellets and gassifying? Or maybe even just burn directly? If I digest them, can I dry the waste product, pellet it and burn (or even gasify)?
Obviously, some fuels are a no-brainer (I can't imagine gasifying the dog poo!) but advice would be appreciate!
I also plan to store the resulting gasses to power both internal combustion engines and to burn directly. Can the two gasses be safely mixed and stored / used together, or is that a BAD idea?
All advice gratefully received!
