Jean
Methane—natural gas—is
an industrial fuel. It can provide combustion energy for cooking
and space heating, but it can also run motors. Convenience in
transport and for vehicle use dictates compressing the gas, but
this too is possible with methane-generated electricity and simple
compressors. The nimble French inventor set out to link all these
processes by the necessary technical elements.
He reports that machinery that shaves rather
than chips the branches and limbs is preferred.
One of these,
a tractor-driven model, was awarded fourth prize in the 1978 Grenoble
Agricultural Fair.
The brushwood shavings must then be saturated
with water. A cubic meter of woody material will absorb up to
700 liters of water over three days if continuously moistened.
A large heap (75 cubic
meters, about 50 tons) of this material could be obtained from
a hectare of careful forest thinnings (35-40 tons).
Pain reports that he heated
his five—room house of 1000 square feet (100 m2) and provided
hot water (at a rate of 4 liters! minute) for its occupants from
a 50 ton pile for six months, but that a 12 ton pile maintained
that output for a full 18 months.
Referring to the work
of Ducellier, Isman, John Fry, Sauze, and others
Five kilograms of finely shredded brushwood compost yield about
1 cubic meter of methane—about 5,500 kcaI—equivalent
to about half a liter of high-grade petrol in energy content
The plastic coil conducted water
around the gas tank while serving as a heat exchanger. By regulating
the flow of water, the temperature of the gas reactor could be
regulated to optimize gas production, which in this example was
about 1300 liters per day
The results are impressive.
From a hectare of fire-prone and unproductive forest, 50 tons
of agricultural fertilizer can be derived along with the energy
equivalent in fluid form, of 4000 liters of high-grade petrol.
Pain calculates the economics
of a theoretical 1000 hectare unit managed according to his methods
and estimates that process energy required is 12% of energy yield,
while counting in all inputs, ores, metallurgy, wood, implements,
and so on, 26%; that equipment can be paid for in five years and
the financing, including interest, retired within 10. All the
while 16 people will be employed at good wages.
Also, the production of industrial cooking oils is primarily
monocultural and inherently devastating to enormous areas of the
planet. Biologically, production of oils requires a more complex
and less efficient energy pathway than plant production of cellulose
and ligneous material.
