Perspectives on Innovation

The days and weeks pass, and, until last week, oil continued to blast upwards from the bottom of the Gulf. As time marches on, the pace of new solutions has slowed as well, yet we still continue to receive submissions from you about how to stop the gushing oil and protect the coastline.

With the end of the Gulf Oil Spill Challenge in sight, we wanted to showcase an innovative solution that was submitted by a student from an Advanced Placement (AP) Environmental Sciences class from high school in New Jersey.

What I love about this piece is that it came from the leaders of tomorrow (students), it’s simple, and it focuses on the future (the clean up) even while many people and politicians remain focused on the past (blame) or the present (capping the wellhead). Here is the submission:

“Recently in our AP Environmental class, my teacher came in and told us about the oil spill.

He then told us about your website and began having us work on the clean up crisis of the oil.

All of the students partnered up and started to try out their ideas, if they had any.

I then came up with the idea to use baking soda, which led to some good results, and which ultimately led to an expansion of the idea:

We discovered that baking soda would create tar balls for a long enough period of time that you could place something underneath them, collect them, and drag them out of the water in tact.

So then my friend and I tried placing nylon stocking on the oil to see if it would allow the oil to pass through, and it worked.

Nylon stockings allow the oil to seep through, but they block the clean water.

The result of our tests culminated in our final idea, which actually cleaned up the water to near perfect quality:

• Place the stocking on top of the oil (the oil passes through this porous barrier)
• Sprinkle baking soda on the stocking and the oil
• Wait up to one minute
• Pull the stockings out of the water, which collects the tar balls and leaves the water nearly completely clean

We tested this in class on a large scale and we were able to accomplish getting the water clean.

I hope this idea helps in the crisis and we wish you the best of luck!”

The days and weeks pass, and oil continues to blast upwards from the bottom of the Gulf. And as time marches on, we continue to receive submissions from you about how to stop the gushing oil and protect the coastline. Because of the importance and magnitude of this disaster, and because we want to keep you apprised of various InnoCentive activity around this Challenge, we are glad to share during the coming weeks the details of several key solutions and ideas we’ve received from you. Today’s post is a summary of a submission by Renate Wortelboer.

Pipes–horizontal or vertical–from which oil leaks under enormous pressure, could be closed by using the strongest magnets available in several sizes.

A custom made, cone shaped strong magnet with a “collar” at its widest diameter to fit the pipe could withstand the pressure of the flowing oil. If this magnet is not strong enough to withstand the pressure, another magnet could be added on top of the cap, like halter weights.

Small crevices could be covered with a layer of small metal and magnets. The entire structure could then be sealed off with bitumen, cold asphalt, synthetic rubber or any other sealing material. To finish, the bedrock could be restored with stones.

Schematic cross-cut overview:

1. Pipe to be closed
2. Main magnet, first placed
3. Extra weights
4. Magnetic “wings” as long as possible
5. Layer of bits of metal & magnets
6. Layer of sealant
7. Layer of stones

Notes:

It could be investigated whether the wings should be attached later or be on the main magnet already. However, an on/off switch will be required for the wings if already attached.

Around the entire structure, to seal it properly, a thick layer of a mixed iron/steel/magnets could be used. When a layer of synthetic rubber, for example, reinforced with any metal is chosen, it would help if the underlying layer still has magnetic properties.

The main magnet could also be composed of magnetic cubes or balls, glued or attached to steel rods to create a cone shape. This might save time.

The aim of this solution is to minimize the oil’s environmental impact to the ocean, land, and life. Coconut Coir (CC) is the fibrous layer outside the coconut shell. It is used around the globe in the manufacture of soil treatments, rope, and doormats.

CC can be used to absorb the oil spill in the Gulf of Mexico. CC is an excellent bio-absorbent, used for horticultural applications and purposes. It also has very good water retention properties.

The individual fiber cells are narrow and hollow, with thick walls made of Lignin and Cellulose. The phenolic groups in lignin are responsible for initiating the absorbent property. Lignocellulosic materials, such as CC, containing a higher amount of phenolic groups are expected to be more effective scavengers for removal of oils and hydrocarbon from the environment.

CC can absorb as much as 50 times its weight in oil.

Further, CC can be treated with keratin protein (found naturally in goat hair) to improve its oleophilic and aquaphobic properties. The chemically modified novel CC pith can be used for oil absorption and to absorb metals (chromium, lead, zinc, etc.) and hydrocarbons, and its absorbing capacity may increase up to 70%.

The advantages of using CC over other natural and synthetic products are many: it is a low cost solution; it is eco-friendly and bio-degradable; it is 100% natural and widely available (the total world CC fiber production is 250,000 tons—India produces 60% of the total world supply of white coir fiber, while Sri Lanka produces 36% of the total world brown fiber output).

Today’s post is a summary of a submission by Michael White.

Michael White, of Templeman Automation, proposes pneumatic barriers made of sintered rubber aeration tubing.  Such tubing is available for aquaculture applications at about $1/ft, making rapid deployment of long-baseline (>1000ft) pneumatic barriers cost-effective.  It can be made of recycled materials, and does not suffer reduced efficiency from salinity encountered by traditional bubblers.  Specifically, the strength, flexibility, and low drag of sintered bubblers make them well suited for towed applications in which a shipboard compressor provides air to a trailing bubbler system.  Such a mobile system has advantages in three depth regimes:

1. Surface – Towed bubbler arrays provide mobile platforms for “corralling” moving oil as more permanent barriers are devised; adapting to immediate ocean current and wind conditions.  Templeman Automation has tested aeration array systems with up to 1000cfm air flow at over 8 knots.
2. Mid-Water – The depth of the towed bubbler system can be adjusted such that oil suspended in the water column is above the array and thus entrained in the rising bubble plume.  Oil is thereby forced to the surface for remediation.
3. Sea Floor – Towed bubblers can be used to “suction” oil from the sea floor, providing a non-contact pressure gradient that is gentle to sea-floor habitats.  The small bubbles created by aeration tube systems transfer beneficial dissolved-oxygen to affected sea-floor ecosystems.

This barrier solution is really an answer to Louisiana’s Plaquemines Parish President Billy Nungessers request for protection of the Barrier Islands.

The floating Barge solution will protect the barrier Islands from being further contaminated by oils coming ashore. There are available between Baton Rouge and Slidell approximately thirty-two hundred and fifty river barges each at least hundred feet long. This number is more than sufficient to produce a barrier structure in front of all the Barrier Islands from nearly Dauphin Island extending west of Grand Island at a fixed position based on the 30-foot high tide mark. The barges—placed in a row nose-to-stern is nearly 73 miles long. And the barges are there now.

These resources can be immediately mobilized within hours, not days or months, and require no dredge and fill permits or forms from USACE.

Additionally, Saint-Gobain’s ChemFab division can fabricate the Teflon barrier material in continuous lengths (this material is used for huge roofing areas at airports and places UK Millennium Dome, and is rated for 250 MPH and 978 Lbs/in tensile.

We would solid-weld the barges together and anchor accordingly, then use skimmers cruising up and down to get the oil against the Teflon barrier all the way down 30 feet.
