PENSACOLA BEACH, Fla. (AP) - Some inventors came with cotton
fiber rolls, others with oil-clumping polymer mixes and one brought
a specially designed rake. Their task: clean layers of crude oil
and tar from a once-pristine Florida beach and prove they have the
right stuff to combat the gummy onshore residue of the massive Gulf
The 18 U.S. and Canadian inventors displayed their science to
save Florida's beaches Thursday in a high-stakes clean-off under
the critical gaze of evaluators. They were winnowed from among more
than 400 people who submitted ideas.
"If we can find some gems out here, we hope we can start using
them ASAP. We are looking for something that spreads easily and is
effective. The answer isn't just one tool, we need a lot of tools
for different weather conditions, for out in the water, on the
beaches, in the marshes," said Darryl Boudreau, assistant director
for the Northwest Florida district of the state Department of
Intermittent rains, winds and a driving surf churned by
Hurricane Alex didn't stop dozens of local, state, Coast Guard and
other officials from coming to watch. Evaluators from the state's
environmental department, which organized the event, and from oil
company BP PLC walked around the tar-covered beach to see the
technologies in action and chat with inventors.
Kalty Vazquez of Miami held a bucket in one hand and with the
other he spread a green-sandy substance called GreenTech over his
plot. Vazquez then raked through the tar and GreenTech and scooped
the raked sand with a strainer, leaving mostly clean sand behind.
He later demonstrated how GreenTech worked in water, helping to
form larger tar balls that are easier to pick up.
Watching closely, clipboard in hand and dressed in full rain
gear, evaluator Daniel Kuncicky had lots of complicated questions
about how the polymer-based product worked.
Nearby, another group blanketed the sand with a cotton-fiber
roll. The idea was for the oil and tar to adhere to the cotton when
it was rolled up.
But the group said it worked best when heavy machinery rolled
over the cotton and pressed it into the sand. Lacking the
machinery, they stomped on the cotton with their feet. Only a small
part of the mess was removed when the cotton came up.
Bill Vasden Jr. grows his oil spill cleanup solution on 1,500
acres in Tampa. The biodiesel and feed starch farmer believes
kenaf, a kind of grass, is the answer to soaking up oil as it
washes on shore. Vasden displayed kenaf booms on the beach.
Auto mechanics have long used the material to clean oil from
their floors, he said.
"It's a fibrous grass, it's renewable and we can burn it for
energy," he said. "We have 1,500 acres of it already."
Among those who came to check out the ideas was Buck Lee,
chairman of the Santa Rosa Island Authority, which oversees
"Whoever invents the magic dust is going to be a millionaire,"
Lee said, as he handled phone call after phone call from people
concerned about the oil-covered beach.
Some solutions were simple.
Jeff Powell demonstrated a tar-ball rake. Powell's
Pensacola-based company, Ellis Trap and Cage Manufacturing, has
long sold crab and bait-fish traps and sand flea rakes. The oil
spill has hit his company hard, so Powell said he came up with
another idea - a rake that traps tar balls and filters out the
sand. In about 30 minutes he raked his plot of sand and left a
Peat moss is Canadian John Green's answer. He demonstrated
Sphagsorb, a microbe-enhanced peat moss. The product has worked in
Canadian oil spills. Ten pounds of the Sphagsorb collects about 40
pounds of oil and tar, he said, as he spread the stuff over his
plot. He glommed up a large wad of tar with his gloved hand to show
how it caused the tar to stick together and made it easier to
Other ideas included spraying microbes onto the sand with
containers that looked like bug sprayers, and mesh matting that
could be removed from the sand after the tar washes on shore.
After an hour, the small section of beach in front of the public
walkway where the inventors demonstrated their ideas looked much
cleaner than when they started.
But evaluators were mum about whether they would choose any of
the ideas or how quickly the public might see them in action.
