Cuban inventor turns trash into farm tools

Cuban inventor turns trash into farm tools

GUIRA DE MELENA, Cuba (Reuters) – A solitary man trudges through a
palm-lined corn field in the Cuban countryside, pulling behind him a
rickety contraption that President Raul Castro would love.

The man, Yolando Perez Baez, is showing off his latest invention, a
spindly, spider-like piece of equipment that sprays pesticide along six
rows of crops, instead of the one row he could dose using his usual
backpack fumigator.

With the backpack, Perez says he would have to walk five miles and take
six hours to finish the field. The new equipment allows him to do it in
one hour and walk less than a mile.

In other words, it fits right in with Castro's quest to cut
budget-draining food imports by making Cuban agriculture more efficient
and productive.

More than five decades of revolution, and the necessity and isolation
that have accompanied it, have made Cubans both skilled at improvisation
and a little eccentric, none more so than Perez, 47.

Using parts scrounged from local trash dumps he jokingly calls his
"warehouse," Perez has pieced together primitive equipment to spray
pesticides, start balky irrigation machinery and speed the harvest of

He even wears a hat of his own creation that protects his face from the
sun, but looks like a cross between a Chinese peasant hat and something
a space alien would wear.

These are not high-tech creations, but, like much else in Cuba, simple
and functional, rooted in common sense and the need to make do with what
is available. They do not eliminate the back-breaking manual labor that
dominates Cuban farm life, but reduce it.

His motor starter is a study in elegant simplicity and addresses a
serious need in a country where major equipment tends to be antiquated
and often in need of parts that are costly and hard to get.


"Eighty percent of the motors here, in this municipality at least, don't
have batteries, don't have starters. It's the first thing to break and
you have to buy them in hard currency, which is very difficult," Perez said.

So, Perez, an agronomist engineer who wears the stained work clothes of
a man that spends a lot of time in the workshop, developed what looks
like a small oil rig equipped with a heavy weight.

The weight, tied to a rope that is wrapped around the engine crankshaft,
is lifted up by the rig and dropped. The fall pulls the rope and cranks
the engine to life.

He has sold eight of the apparatuses for the equivalent of just over
$100 each.

One of his customers, Jorge Suarez, praised the machine after it started
a massive diesel engine for his irrigation system. As water poured out
of a pipe into his cabbage field, he said, "If we don't invent what we
invent, then we would be in bad shape. Look, if this man doesn't invent
this, I don't know (what we would do)."

Necessity is said to be the mother of invention, but Perez said it was
something slightly different.

"The main thing is to be faced with the problem," he said.

Perez works at the "First of May" agricultural cooperative in Guira de
Melena, which is about 35 miles west of Havana.

Under reforms by Castro, farmers are making good money, said coop
president Jose Miguel Gonzalez said, but only spend it on new equipment
when they are convinced it works. The jury was still out on Perez' new
fumigator, he said.

Not to worry, said Perez. He has other machines in the works, including
a revolving sprinkler system, and, in the end, each invention is just
another small step toward a better Cuba.

With "a little that I put here, and another little bit that another
Cuban puts there, the economy grows," he said. "The small things have to
be noted because sometimes they appear insignificant, but together they
are a lot.
