what about making bricks out of it? add a hardener
and press it into building materials.

C is infinitely easier to sequester than CO2. Is a solid at room
temperature and pressure.
speaking
of pyrolysis... what can we do with the carbon left over in the
charcoal
instead of burning it? this is a solid carbon that otherwise does
not
get into the atmosphere. can it be compacted or somehow removed from the
short term carbon cycle? i know it sounds dumb, but if we can turn loose
what took millions of years to put away naturally why cant we find some
way
to speed a reversal artificially? Mama pulled all that carbon out of
the
cycle and buried it with solar power, cant we do anything to help
her do it
again?

1000 gallons methanol per acre with hemp if using
pyrolytic distillation.

im all for the efficiency argument, but COME ON
PEOPLE! doesnt anyone
believe in using something OTHER than corn and soy?
they are NOT the best
feedstocks anyone could use for fuel! move to a
better supply, not a higher
yield. this is ridiculous! if the supply was
a high density stock the land
requirement would be porportionally
lower.
for diesel replacement assume we used castor in the
USA:
-oil yield would be roughly 151 gallons per acre compared to
48
gallons of soy oil.
-THEREFORE one acre of castor would eliminate
the need for more
than 3 acres of soy.
which means those other 2 acres
of new empty field could be
used for food or- OH NO! TREES!
for
gasoline replacement assume we use sugarbeets (not very good, but
more
climate friendly) in the USA:
-ethanol yield would be 412 gallons
per acre compared to 214 gallons
of corn ethanol
-THEREFORE one acre
of sugarbeets would eliminate the need for
1.9 acres of corn.
you see
where im going with this?
by selective breeding of some of the more
tropical varieties of high density
stock, we can slowly push the growing
regions further north, increasing the
supply density, and lowering the
acreage needed to supply the same amount.
WE DONT NEED CORN OR SOY FOR
FUEL! i might be raving like an idiot, but
noone can seem to understand
that corn and soy are not the only crops in
the
world.
