LIVING ON SUN, WATER, WIND, GRASS, AND COMMUNITY

Nearly everyone who has been to the solar village Gaviotas, east of the Andes
in Colombia, calls it a utopia.  But it isn't, says Paolo Lugari, its founder. 
That word means in Greek "no place."  Gaviotas has existed, however improbably,
for more than 30 years now.  Lugari says it's a "topia" -- simply a place.

When he first saw it, looking down from a small plane in 1965, it surely looked
like no place.  There were two crumbling warehouses abandoned by a road crew at
the end of a failed attempt to cut a highway across the huge, wild, wet savanna
called the llanos.  No one lived on the llanos except a few scattered ranchers
and the Guahibo Indians, who fished and hunted in mosquitoey forest strips
along the rivers.  The soil was so toxic that nothing but tough grass could
grow.

If people can live here, they can live anywhere, Lugari thought.  He set out to
show that they could.

His secret weapons were the professors and students of the universities of
Bogota.  Lugari dropped into the office of a mechanical engineer named Jorge
Zapp and asked, "Can you build a turbine efficient enough to generate
electricity from a stream with just a one-meter drop?"  He went to Sven
Zethelius, a soil chemist and asked, "What can we grow in that soil?"  He
posted notices inviting doctoral theses on how to press oil from palm nuts, how
to raise hundred-pound wild capybaras for meat, how to make fiberboard out of
llano grass.

Most of these experiments didn't work, but once the engineers got out to
Gaviotas, a 16-hour tire-destroying jeep drive from Bogota, they began having
other ideas.  Necessity surrounded them, and they produced a stream of
invention.

They found that 14 parts of that terrible soil combined with one part cement
hardened into a stony substance they could use for dams and buildings.  They
made water pipes by lining ditches with soil-cement, laying down long
polyethylene tubes filled with water, pouring more soil-cement on top, letting
the whole business harden, then draining the water and pulling out the plastic.
 
Trucks could drive over those pipes without crushing them.

They attached water pumps to see-saws; kids provided the pumping power.  They
designed ultra-light windmills to catch the mild but steady llanos wind without
being blown over by the occasional llanos gale.  They invented solar
water-heaters so cheap and effective that Gaviotas started a business back in
Bogota, installing them everywhere from the president's house to a
30,000-resident slum housing project.  Often engulfed in mountain clouds,
Bogota is no ideal place for solar power, but the Gaviotans developed a
collector so efficient it could catch scattered sun energy even on cloudy days.

The technical and architectural triumph of Gaviotas is its hospital, cooled by
the wind, heated by the sun.  The sun also provides hot water, boiled
sterilized water, and the heat for six pressure cookers in the kitchen, plus
enough electricity for the lights.  By the time the hospital was built,
Gaviotas had several hundred inhabitants, including the only doctors, nurses,
and teachers for hundreds of miles around.  People came there for medical care
and sent their children there to school.

There were fish in the river, and cattle could eat the grass.  Zethelius had
discovered enough decent soil on the riverbanks to plant mangoes and cassava
and cashews, but not enough to provide fresh vegetables for a growing
population.  So the Gaviotans learned to grow lettuce and tomatoes and
cucumbers in containers of nutritionless rice hulls, washed with manure tea.

They kept searching for some plant that could survive the llanos soil and
finally found it.  A Caribbean pine from Venezuela thrived, they discovered, as
long as they dipped the roots of its seedlings in a fungus, a mycorrhyza, which
was missing from their soil but importable from the pines' native territory. 
Without knowing quite why, they planted hundreds of acres of pines.

As the pines grew into forests, the Gaviotans found a use for them.  They
tapped their oozing gum, which could be distilled (with solar energy) into
turpentine and a valuable resin used in paints, glues, cosmetics, perfume, and
medicines.  There was a huge market.  Gaviotas had a new industry.

The pines dropped needles and built up soil.  They cooled the ground, slowed
the wind, raised the humidity.  Suddenly new kinds of plants sprang up beneath
them -- hundreds of kinds of plants.  The rainforest, not far to the south, had
once grown here, and now, through seeds carried by birds or roots creeping up
from the river-edges, it was returning.

The Gaviotans imagine themselves planting pines in expanding circles out into
the llanos, harvesting gum for 100 years, leaving rainforest behind.  Meanwhile
their technologies for pumps and collectors and windmills, all simple,
affordable, and purposely unpatented, are spreading throughout the world.

"This is what the world needs," said Aurelio Peccei, aged founder of the Club
of Rome, who visited Gaviotas ten days before he died.  I agree, not only
because of Gaviotas's technical ingenuity, but because of its attitude. 
Gaviotans live in peace surrounded by narcotics dealers and guerillas.  They
live without guns, without pesticides, willing to serve and teach all comers. 
They count their wealth in sun, water, and community.  They believe that
solutions can come from anyone, anywhere, even from, most especially from, the
Third World.
