Mal,


Ok, I'm following you now.


Yes, the function I see for solar is to reduce the bio-fuel
requirements by around 60%, using coke as an baseline, 60% of the fuel
is used to heat the reaction chamber. Source: "The chemistry and
manufacture of hydrogen by Philip Litherland Teed"

So I'm thinking if the bio-fuel is first baked to carbon in a solar
furnace, then the solar furnace is used to generate steam and the
proper reaction temperature there would be a ~60% fuel reduction.


I think methane is the way to go IF you're already raising livestock,
I can't make the numbers work electrolyzing water, maybe you can see
something there I didn't. Like everyone else I got started with algae
for oil, which was appealing not only for the oil but the remaining
bio-mass for garden compost.

I've lost the original posts, but
couldn't you "grow" goats? Let them
harvest whatever they can, then use
their scat for fuel?

Otherwise I'd subscribe to the KISS
principle and go steam

 



Whenever I get the woodgas bug up my butt (this happens somewhere close to
annually) and start gathering up parts to build it and figuring out what
else I need and what the benefits and drawbacks are I always end up looking
more into steam power or methane production.  Methane seems to be rather
complicated too and steam seems to be a little simpler except when it comes
to the engine to drive a generator.  Making steam using either wood or a
solar furnace seems to be easy enough.  Making a solar tracker doesn't seem
to be too complicated.  It's just a matter of what do you feed the steam
into to make electricity.

Ulysses,


I'm not quite sure; a solar steam process uses solar energy to produce
enough steam to drive every stroke of a steam engine, while the
bio-fuel process first uses solar energy to grow the fuel feed-stock,
and then uses only enough solar heat to drive the chemical process
that produces the fuel to drive every stroke of an engine. To my eye
there seems to be two different processes at work here.

I've run the numbers on steam, and have NOT run the numbers on
bio-fuel gasification that's what I'm up to now, in order the see
what's there.
