In the countryside in the south of Europe you often see small scale farmers and others with small plots of land burn all kinds of garbage. Just like that.
It is difficult for them to properly recycle the tree branches and such. Too labor intensive to do something useful with it. The big chunks of
wood are stored for the stove in the winter.
To have it collected by garbage trucks is a waste of gasoline.
Now how to store this energy conveniently? Perhaps sell it, speculate with it even.
Have some super-efficient stove with all the modern filters that you can insert any kind of garbage in and out comes a fluid that can be used for (clean) energy later. Like hydrogen. It could charge an electric car, bike or moped perhaps.
Anything is better than just burning it.
Make sure your designs don't have a "Goldberg factor".

||First converting the heat into electricity to create hydrogen is inevitable it seems? Then storage in a battery or just feeding it to the electricity grid makes more sense...
||First build a methane digester, then wrap it in water lines. Next use a solar powered wood chipper to turn that waste into shavings.
||Heap the shavings onto the methane digester and collect the gas.
Plumb the water lines through the floors of your buildings for free heat as the pile decomposes. The BTU's given off by a compost heap equal the ammount of heat given off by combustion just over a much longer time.
||//some super-efficient stove...
||How does that work? Magic?//
||Just moving to rocket stove designs gets you much more
efficiency, I see numbers as high as 40%, but even 10% is
worth it for such a minor tweak. The second benefit is
better combustion leading to less soot, air quality can be
horrific in areas with lots of wood burning and poor
ventilation, take the whole Chamonix valley as an example,
if the winds aren't kind, it's like smog.
||The idea isn't really an idea. Waste wood should be taken
away, burned for biomass energy and the ashes
treated/optimized as fertilizer and delivered back as free
trade for the wood.
||If you burn the wood in a retort not only are most of the gasses combusted but you're left with bio-char which, when activated in a compost heap becomes super-fertilizer.
||So he's been around the bakery on and off for a few decades
and yet doesn't comprehend basic chemical elements.
||Maybe if you were to take all of that waste garbage and
bombard it with some high-energy neutrons until you break it
down into atoms, using utter gobs of energy to do so...
||But why create hydrogen when you can just turn lead into
gold with the same sort of magic?
||I'll go for what '2 fries shy' proposes. Because the situation I am trying to overcome is what bs0u0155 describes in the Chamonix valley. It can be like smog.
||It would be nicer if the production of methane can be prevented. I picked up in the popular press that hydrogen is clean.
||My apologies for my lack of knowledge in chemistry, it is not my field. Busy with other things during my absence from the Halfbakery. Shall I delete this entry then?

||Absolutely not, this is a chat site, not a
government regulated technology development
collective, we're not NASA. It can be a good
place to learn too if
you connect with the right people. It's also entirely
okay to be wrong during that process of learning.
Knowledge is gift to be shared, not a cudgel to
beat less informed people over the head with.
||That being said, there's this guy named Rube
Goldberg that made cartoons of outlandish
contraptions that did a simple job with as many
steps as possible, so while this might work, it's got
a bit of what I'll call the Goldberg factor. You could
make a stove that burns garbage and
uses the heat to generate electricity that you
then use to
hydrogen, but it wouldn't be very efficient.
keep thinking about stuff like that and asking
questions, that's how you learn.
||//If you burn the wood in a retort not only are most of the
gasses combusted but you're left with bio-char which,//
||If you burn it cleverly, you can use the heat to then distill the
wood and get useful stuff! Turpentine! Creosote!
||You know this does bring up an interesting
concept: "Where's the line that this would have to
cross to be efficient enough to make this worth
||You'd need a mechanism to
scrub this so it wouldn't pollute and it would have
to work better than trucks that burn fuel to cart
garbage to the landfill. There's a number you'd
have to determine you'd shoot for. With some sort
of mechanism burning garbage and providing, say,
additional heat for a water heating system where
the heat is stored in an insulated water tank,
scrubbers or something removing the smoke, then
you take the resulting ashes
and cart them someplace with a truck that
comes maybe every 6 months opposed to every
week. You'd have to save money, energy and get
the cost amortized over some period of time. If it
cost $5,000 to build this and it saved you having to
take the garbage out ever again, got a little
reduction in your water heating bill (it wouldn't be
much) and reduced landfill cubic footage by 95%
and cut garbage truck fuel trips and fuel
consumption by 90%? That's something.
||I wouldn't bother with electricity, not enough of a
prize for the effort, but if you change the goal to
just saving truck trips to the dump, you might have
a challenge worth looking into.
||And here's the best part, while trying to solve this
problem you might accidentally come up with a
solution to a problem you weren't even looking for.
Happens all the time.
