Food Factories in the Future
Food factories will eventually make farms obsolete.
They take up a fraction of the land of farms they replace, because
crops in them can be grown in shelves one or two meters apart. Suppose
a food factory covers 100 hectares (250 acres), like a shopping
mall or a large office park. It is 25 stories high (80 meters),
and grows vegetables on 40 layers of shelves two meters apart. That
gives it about as much growing area as a 4,000 hectare farm. There
is no winter in the building, and according to the Yomiuri article,
it takes about a month to grow a head of lettuce, roughly half the
time needed by field-grown lettuce, so the growing season is at
least four times longer than a regular farm. There are no insects
in the building, no deer, few rodents, no weeds, drought, or floods,
and there is always the right amount of light and fertilizer, so
little food is lost to spoilage. Automation is much easier. There
are no rocks, hills or irregular areas, so robots can process the
crops. Robots cannot work in the hills of Pennsylvania or the paddies
of Japan. Overall, the 100 hectare facility is at least as efficient
as a 16,000 hectare (40,000 acre) farm.
The total land area of the U.S. is ~917 million hectares.
Forty seven percent, ~430 million hectares, are used for agriculture,
including ~161 million hectares for crops.30 The other
269 million hectares are used for livestock, including arid land
not suitable for crops. Roughly a quarter of U.S. food is exported.
Someday this agricultural land might be crammed into an area thousands
of times smaller in giant complexes of buildings hundreds of stories
high nestled in the Rocky Mountains, on the moon, or in some other
location where land is cheap. Or, you could cover the five boroughs
of New York City (800 square kilometers; 80,000 hectares) with buildings
as tall as the World Trade Center towers (411 meters), which would
produce as much food as ~66 million hectares of crop land, enough
to feed about half the U.S. population.
As old fashioned two dimensional outdoor farms become
obsolete, a tremendous amount of land will be freed up. It will
be used for houses, or reforested and returned to nature. Agriculture
is the most destructive industry on earth. It causes deforestation
and erosion. It depends on pesticides and fertilizer. Monocultured
crops reduce genetic diversity. The sooner farms are replaced by
compact enclosed factories, the better it will be for the ecology.
People may object to food factories, regarding them
as dehumanized or unnatural. Farms and greenhouses look unnatural
to me, but they are inviting places. It will be spring year-round
in part of the food factory, with blossoms, honeybees, and bright
artificial sunlight. Food factories in the far north will do a lively
business during the winter hosting people hungry for a touch of
spring, summer or fall, or all three the same afternoon. Acres of
grass and trees might be set aside as a park, with artificial brooks
and real fish.
In the distant future, indoor farms may be supplanted
by food synthesizers. This will require new discoveries and new
biotechnology. Cold fusion is likely to come into widespread industrial
use long before these technologies can be applied radically, or
traditional agriculture done away with altogether.
The Dangers of Cold Fusion
There are legitimate concerns about the dangers
of cold fusion. They fall into two categories: radiation, and long
term environmental threats from the irresponsible use of cheap energy.
Some scientists believe that cold fusion is
not fusion per se, it is zero-point energy, or shrinking
hydrogen atom "super-chemistry," or some other exotic phenomenon.
Even if one of these hypotheses turns out to be correct, there is
no denying that cold fusion includes a nuclear component. Cold fusion
produces helium and transmutes cathode metals. Occasionally it produces
tritium. Autoradiographs show that some used cathodes are radioactive.
Perhaps these nuclear transmutations are a side-effect of zero point
energy, or perhaps the "conventional" cold fusion nuclear theories
are correct and the transmutations are the sole source of energy.
Either way, nuclear reactions and radiation are inherently dangerous,
and must be treated with respect. It would be foolish to treat a
cold fusion cell like a solar cell or some other source of energy
with no possible side effects. A cold fusion engine will not be
as dangerous as an internal combustion engine, which requires explosive
fuel and produces deadly carbon monoxide. But it may require some
shielding, and possibly a radiation alarm that could trigger an
emergency cutoff switch--unless the process could be tuned
and certified not to produce ionizing radiation. A fully
developed theory to explain the cold fusion reaction might give
us pinpoint control, and it would give us increased confidence that
cold fusion motors cannot produce large, uncontrolled bursts of
radiation under any circumstances.
Some people fear there may be a hidden, long
term threat to the health of people who work in close proximity
to cold fusion reactors. So far, nobody has detected dangerous levels
of x-rays or other emissions from a cold fusion cell. The autoradiographs
prove that cold fusion does produce low levels of radioactivity,
but the levels are so low that scientists have difficulty detecting
them with sensitive instruments. Compared to the radiation from
televisions and the natural background of radiation from space,
radon and other sources, cold fusion radiation seems likely to remain
so low as to be nearly undetectable. Still, cold fusion might conceivably
produce some unknown form of radiation or some other deleterious
effect. We will have to make sure this is not the case, by exposing
rats and other laboratory animals to unshielded cold fusion reactors,
and by carefully monitoring the health of the first group of people
who work with the reactors every day.
When cold fusion was announced in 1989, A. Lovins,
J. Rifkin and others said they hoped it is not real because mankind
would do great harm with such a powerful tool.
31 People compare cold fusion to giving a baby
a machine gun. I do not understand this logic. We can easily destroy
the earth with the technology we already have. We do not need cold
fusion, nuclear bombs or any advanced technology. We are using fire,
our oldest technology, to destroy the rain forests. The ancient
Chinese, Greeks and Romans deforested large areas and turned productive
crop land into desert. The destructive side effects of technology
in 2000 BC were as bad as they are today.
Cold fusion could become a powerful force for
evil. Used unwisely, or with malice, it could exacerbate social
problems ranging from boom boxes to unemployment and environmental
destruction. But that is true of every technology. Unless it can
be used to make cheap nuclear bombs, cold fusion will not threaten
our future any more than fire or automobiles already do. If people
act irresponsibly, and laws are not established to protect the ecosystem,
we will end up destroying the earth no matter what tools we use.
Our only hope is that people will act wisely, and they will treasure
and protect nature. That job will be far easier with nonpolluting
cold fusion. We can use this wonderful new tool to eliminate pollution
and clean up the earth if we choose to, or we can destroy everything
with it. It is up to us. Our destiny has always been up to us.
