UPDATE!!
Since a reader has posted they already set up a wiki I ported the content from my wiki to that one.
Having two separate wikis defeats the purpose of having a single point of collaboration.
There are a lot of good ideas on the wiki and I encourage you to drop by, review the current solutions, add your feed back and submit your ideas.
The new wiki is here: oilspill.wikia.com
First, let me start with a little rant.
BP Asks For Ideas Capping Gulf Oil Spill… But Are They Serious?
Personally, I have several ideas on how to cap the Gulf oil spill and I am sure there are millions of others that do as well.
Even even if people don’t have ideas to suggest, there are plenty of people that are more than willing to contribute.
Let me give you an example right here, right now buy doing both!
If BP is seriously asking for help, then why are they hindering those from whom they are seeking help from actually helping them.
Before I continue with my rant about BP let me announce that after reading about there request for help via twitter 4 minutes ago I have setup a Gulf Spill Wiki at http://SpillWiki.AlexanderHiggins.com where those interested can truly suggest and collaborate on ideas to fix the Gulf oil spill.

Central Command Turns To Twitter To Solve The Gulf Oil Spill. Uh … http://bit.ly/bLReUR
Before I continue my rant, let me explain why open and transparent collaboration is needed to solve this mess.
BP has been continually resistant to releasing information that would actually contribute to coming to a viable solution.
These missing facts are indeed relevant, and indeed a pre-requisite, to coming to a solution for the problem.
For example, a 400 ton massive dome was lowered to the seafloor which didn’t work. Why can a structure of that weight not be used to crush the pipe shut?
I am almost certain that BP has considered such an option. But by not sharing the reason that option is not feasible, refinements to the suggestion can not be made until a valid solution is reached.
Scientist would most likely need scientific data about the leak to come up with ideas? The viscosity of the oil. An estimation of how much methane is coming out of the pipe. The velocity and pressure of the fluid leaking.
These missing variables combined with misinformation about the extent of the spill helps to further allude solutions.
For example, using BP’s estimates of the spill leakage, there is 3/4 of a gallon of water coming out of each of the three leaks. Mind you that a garden hose has a flow rate of 1 gallon every 10 seconds.
So if we are only looking at little more than 8 garden hoses of oil leaking, then one could hypothesize that the leak could be filled with some kind of expanding foam, much like weather sealant.
Obviously, we are dealing with much more oil at a much higher pressure and a much higher velocity.
But without accurate data it will be hard to formulate any ideas.
I am a programmer, so I will use a programmer’s analogy to summarize the problem.
At the end of the day here, this would be like Microsoft asking for programmers to help fix a massive bug in the source code of their Windows Operating System software while refusing to disclose the source code that contains the bug.
I am confident however, that through open collaboration and with the pooling and sharing of the knowledge that is publicly available such a solution will EVENTUALLY be obtained.
I am also confident that the questions that I have raised here and the Ideas that I present here can shape into living and breathing documents on the http://SpillWiki.AlexanderHiggins.com
Let us keep our fingers crossed that the collaboration bears some fruit and helps end this Catastrophic failure once and for all.
Two of my better ideas (again feasibility can not be determined without better data)
- Freezing The Pipe
Perhaps this one seems like it comes out of a science fiction novel.While convention wisdom tells us that a frozen pipe will explode, perhaps by thinking outside of the box, we can make this work.
For example, First we cut off the the rig where the pipe comes out of the seafloor.
Then we shoot liquid nitrogen straight down the hole.
When the liquid nitrogen hits the oil, and the methane it freezes it in place.
While in a normal situation the pipe would burst, since this pipe goes 13,0000 feet straight down to the oil deposit and it is already encased with cement the pipe would not explode.
Again, we need data on the pressure and velocity we are dealing with.
- Freezing The Leak ItselfThis idea would be to freeze the leak itself using liquid nitrogen then covering the frozen leak with cement.
This would play off the previous example. But instead freezing the oil in the pipe, we essentially create a dome of ice around the top of the pipe. Then we can cover our Ice cube with steel mesh and cement or perhaps some other kind of material.
- The “Silver Bullet Method” This method, which I call the “Silver Bullet Method” involves plugging the pipe with a projectile.
I am not sure why just using an high explosive to seal the rig won’t work. Initially I conceptualized mixing the explosive with an ordinance that would in effect “weld” the pipe shut.
I also consider, wrapping a pipe bomb around the tube. This would exert inward pressure on the steel tube an in effect clamp the case tight.
A theory has been developed on why this may not work, but it involves a catastrophic – end of life on earth – explanation, so I won’t go there… for now.
But I am sure this has been considered by BP and others in the Government’s think tanks (the do have the think tanks working on this right?).
However, since BP is not disclosing the ideas already submitted and hence not giving reasons why those ideas wont work, I will assume that this suggestion has been discounter and present an alternate version thereof.
I call it the “Silver Bullet Method”.
Again, the pipe is cut so we have only few feet of piping stick up from the bed of the sea floor.
The pipe going from the seafloor to the oil deposit is more or less like an ice cream cone, except the top of the cone is somewhere around 2 feet wide (to tired to look up the actual numbers) and the bottom of the cone where it meats the oil deposit is about 9 inches wide.
The idea hear is to make bullet, say as big as a telephone pole and shave it to fit to the inner dimensions of our graduated cylinder.
I’ll let the PHD’s suggest the actual material, although this cartoon suggest the material should be cork. (A little bit of comic relief).
We take this bullet here and we turn it into a projectile shooting it right down the shaft of the rig.
It could get hairy. So looking at this basic concept, we can further refine it.
Once again, we need data from BP.
We need to make sure we don’t over shoot or risk blowing out the sides. How much pressure does this shaft support?
In fact, perhaps slightly undershooting would work under the premise that the side of our bullet has several “fishooks” on it.
I am thinking something like the side of a cheese grater.
When our “silver bullet” reaches a certain point, these “hooks” actually dig into the shaft preventing our silver bullet from being shot back up the shaft.
Even if this doesn’t contain the spill 100%, it would probably slow the flow of oil enough to get a cement line into the shaft and seal it off.
Now I will continue my rant.
Why hasn’t BP done the same? I literally took a whole 5 minutes to setup. And this was my first time ever setting up this application.
Instead they posted this catastrophe of a form that even the worse internet marketer’s in the world could tell you would not get many conversions (actual submissions).
Speaking of internet marketer’s, why haven’t they hired a professional firm to deal with this? To be honest, I haven’t seen any marketing out of BP period.
Not even PR to help them save face.
Instead, I read of ideas being submitted to which BP responded by threatening to sue the submitter if they turn the idea public.
Are you kidding me? Actually, the more I learn about this situation the less shocked I am about the most appalling of things concerning this firm and Big oil.
I’ll probably return to this rant later, but right now I am really tired.
And that Wiki is sitting there waiting for me, so let me go and learn how to use it!
Update: Back because I just can’t get this image out of my head
I was going to tear it apart and throw it in another post but… this just needs to get out. If this is what we are facing, it could explain BP’s unwillingness to cap the well.
It also means we need to get cracking on those ideas.
From Slashdot:
“Here’s a listing of several scientific and economic guides for estimating the volume of flow of the leak in the Gulf of Mexico erupting at a rate of somewhere around 1 million barrels per day. A new video released shows the largest hole spewing oil and natural gas from an aperture 5 feet in diameter at a rate of approximately 4 barrels per second. The oil coming up through 5,000 feet of pressurized salt water acts like a fractionating column. What you see on the surface is just around 20% of what is actually underneath the approximate 9,000 square miles of slick on the surface. The natural gas doesn’t bubble to the top but gets suspended in the water, depleting the oxygen from the water. BP would not have been celebrating with execs on the rig just prior to the explosion if it had not been capable producing at least 500,000 barrels per day — under control. If the rock gave way due to the out-of-control gushing (or due to a nuke being detonated to contain the leak), it could become a Yellowstone Caldera type event, except from below a mile of sea, with a 1/4-mile opening, with up to 150,000 psi of oil and natural gas behind it, from a reserve nearly as large as the Gulf of Mexico containing trillions of barrels of oil. That would be an Earth extinction event.”

Quick Connect Fixture:
Build a large steal plate designed to fit tight, but easily over the leaking pipe with a 1 to 2 foot ID quick connect fixture (exact design of quick connect to be determined). Maneuver the fixture over the broken pipe and weight or anchor it to the floor. the size of the plate would allow options for anchoring. the space left between the quick connect and the pipe must be minimal as to not allow for ice crystal build up. after securing the quick connect, use robots to connect the mile long pipe lowered from a ship. the process would never stop the flow and this would reduce the pressure that would lift the fixture. the idea is to make connecting to the leak a well known process.

You may mention this in your "rant", I didn't read it all. Regarding liquid Nitrogen, I wonder if you couldn't also use it for the oil slick. Large net between boats, blast the surface of the slick with it, crack up the largest pieces and haul it in. Very rudimentary I know. Just a thought.

3 miles in length of bangalore torpedos. We disintegrate the entire oil pipe from top to bottom, let the earth rush in & plug the hole.
Only question is…would the earth rush in & plug the hole?

The wiki concept is one I’ve been exploring myself setting up a wiki at http://oilspill.wikia.com. I’ve tried to get the Wikimedia Foundation to do it as well as Innocentive.com but so far no luck. I’ve also tried to get the Unified Command to take this up or at least release engineering data as you suggest with no luck.
Wikia uses mediawiki and they don’t require registration which is key. I think you need to let guests edit without registration. I think it’s a big enough leap for some people to even try the edit thing much less making them register. I’ve had no marketing means and haven’t received many posts. And since at least two people have thought about this enough to try it (you and I), we need to start thinking about ways to aggregate the information from multiple wikis, maybe not for this but for future open innovation efforts. I’d love your thoughts..

of course I forgot to mention the best solution. The best solution is for the Unified Command to set up such a wiki and we should all call our reps in congress and demand as much. We should also demand that all relevant engineering data be released to give the motivated engineers and laypeople alike the information they need to develop the best solutions.
Not until we’ve done these things and empowered the collective intellect of the world can we begin to say all resources have been brought to bare on the crisis. The congressional switchboard number is (202)224-3121. You can call that and ask for your representative. The Unified Command suggestion number is 281.366.5511.

Justin,
I think perhaps that you put your finger on the problem when you said it is a big enough leak to have someone even edit.
Perhaps a wiki is to techinical for most users which could be a double edged sword.
While it will stifle a majority of visitors from contributing it also will stop loads of spam or even less education/useful information being sumbitted.
In any case, after seeing tens of thousands of hits on the wiki in the short time it has been up with no contributions, I think I need to through together a custom solution to get people collaborating.
I like what you have set up already, but even having ideas myself I am confused how or where I should add those ideas.
I also don’t want to just copy what is on your site and reformat it in a way that is more user friendly (but I am thinking about it).
In any case, your post and this problem points out another problem. How to aggregate solutions and data from multiple wiki’s or even forums.
I see a lot of ad hoc suggestions and a discussions of those ideas. But the need is to aggregate those ideas.
The brain is cranking and I am thinking of programming a simplified forum where the main page allows you to add an idea using a form with a field for title, summary and details.
Then ideas can be aggregated from multiple sources which then can be expanded upon and rated.
Like I said… This has me thinking.

Thanks for the contributions you made to that wiki. You certainly added a lot of content (or someone wanting to appear to be you..this blog was the id and it included concepts you mention here.)
The license at Wikia is cc-by-sa so i think you can do whatever you want with the content with a link to the specific page the content was taken from so theoretically someone could look at the history and see who contributed what. I think it would be most helpful to have the license public domain so the copying and sorting of information doesn't have to be done carefully (with attribution link in edit summary), but I wasn't able to change it.

Oh yes and I definitely think a form to make submissions easier would be helpful for those uncomfortable with editing the wiki. Other wiki editors could then take the information from the form and properly place it in a larger categorized solutions list or make other appropriate insertions.
Perhaps along with an “edit” link next to each category of solutions there could be an “add your idea or comment” link that opens the submission form. Then even basic users would self categorize their submissions, making further editing easier as well as making the unedited wiki/forum hybrid much more effective than a forum alone. I think this effectiveness comes from getting everyone on the same page so everyone knows what’s already been suggested and can start thinking about the new ideas or the next level of issues regarding particular solution implementation challenges and issues.
I don’t really know about a broad multi-site wiki aggregator. In my mind it would be something like indeed.com is for job posts but much harder to implement. I think, baring advancements in artificial intelligence, the aggregation would simply consist of a listing of similar wiki articles across the web perhaps displayed in a helpful side by side manner with some attempt to line up sections.
In terms of making a wiki more user friendly for the purposes of open innovation…I found that a difficult thing myself. I think clearly instructions and norms for idea placement are necessary that differ from Wikipedia for example. It might be easiest to just have everyone post an article with their idea but then you’re probably left with a bunch of articles with repeating ideas. I think it’s good to channel users first to a solutions list so they can see what’s already been suggested and use their creativity and contribution effort efficiently. I think this also facilitates and motivates the collaboration that is so compelling with a wiki. It would be nice to somehow achieve this benefit without an instructions list which might turn some people off. I think it would require changes in the wiki software sort of along the lines of the forum concept you suggest.

Yes it was me that added that content. Even the first edit by anonymous was me.
You can probably just add a disclaimer at the top of the wiki that the information is public domain.
The problem is that you could then only add multimedia that is also public license.
I really have a feeling that BP is lying about this syphon contraption working. But even the possibility that it is has kinda of taken the steam out of my ambition to code a web site that we I mentioned.
The first indication that this isn’t going to work I will get cranking on it.
As far as copy the content onto my own wiki it A) segregation of ideas defeats the purpose of collaboration and further exacerbates the problem and B) would penalize the site with lower page rank from showing up in search engines. Hence one wiki with possibly better ideas would not be visible to the public.
Since you had your wiki up first, I decided to post my ideas there.
The idea is excellent and as I said “Does BP really want your suggestions?”
I mean I had to jump through hoops to submit that PDF to them.
I highly doubt non-techincal (web wise that is) users will be able to submit the form. I know computers inside and out and it was a bit challenging to me. Perhaps because the Form was trying to make me submit via outlook when I use windows live mail. But that is because outlook doesn’t support my web mail (hotmail – which is a microsoft product so go figure) with out a special plugin.
Anyway. Your idea is right there. I think the anonymous thing will help.
I think your lack of marketing may be the problem.
Like I said, perhaps the requirement that the user can figure out how to at least edit a wiki page is not that bad of a thing.
I didn’t like however, that the wiki automatically creates a bullet every time you hit enter, which forced me to go into source code view to type up my ideas.
Just get the word out and those with worthwhile contributions will make them.
Post the wiki on the web 2.0 sites that I have in my bookmarks plugin.
Also add badges to the wiki to bookmark the wiki, share, retweet etc, and you will get people there.
Also post it on forums where people are discussing it and on blogs as well.

Create multiple power packs (small submarine size boxes filled with batteries)to be used as heaters to heat the cap so oil will flow.The boxes could be engineered with arms with heat plates for hands. They could be placed with subs in multiple positions simultaneously.Once packs energy is depleted 2nd shift starts and first shift recharges and so on.Heating the cap at the source may work better than hot water.

I feel I have a solution.
Go to a place earlier in the pipe and lower a Joint pipe that is split open that runs parallel to the pipe but has a valve on top that would remain shut and allow the oil to continue to spill
Once this joint pipe is in place it would clamp shut around the pipe like the jaws of life. Creating a proper seal while keeping the spilling pipe in tact and flowing as it was
Now they would run a pipe from the top valve to the surface. No oil running through at that time. Once complete open the valve and lower in drill through the pipe that would puncture the spilling pipe. To allow the pipe to spill through the main hole and now the pipe that is leading to the surface.
Then lower a piece of pipe after the joint piece that would clamp around and cut through and seal off the far end of the Spilling pipe which would redirect all the oil to now enter the pipe leading to the surface.
This would allow for no excess of built up pressure.
Perhaps leave a valve on the end piece that clamped off the main seal in order for them reestablish how the pipe was before. But now it would have these safety measures in place.

I think the situation in Gulf is hard for most people to really grasp. Many people have all sorts of Ideas with no underwater experience. And no real clear breakdowns of the actual pipe used. Me I am a Plumber and Pipe Fitter from my view I see pipe that is broken and ruptured and only know what I would do if it was on land. But I do have some ideas here they are.
Idea #1 is remove the piping above the BOV mount up a Valve on the flange and either pipe to the surface or simply close the valve!!! Some how I think they have already thought of that so there must be a reason why they have not done so already…
Idea #2 use a mechanical Mega lug flange on the end of the pipe that is spewing oil and mount up a valve in the open position and then close the valve or pipe to the surface once the installation is in place and secured with thrust blocks of some sort.
Can be seen here: http://www.ebaa.com/pdf/Brochure.2100.pdf
Idea #3 If at all possible to hot tap into the pipe in front of the open end of the pipe that appears to be laying on the sea floor. If drilling it is possible use a critical service bolt on Tap/line stop fittings. Which can be seen at http://www.teamindustrialservices.com/prp/pdf/hottap.pdf
These products act as bolt on saddles and are highly effective in hot main line service applications. Once this is installed a line stop can be inserted in the line and or a valve can be mounted to accept a Valve and pipe to pump the oil to the surface. Once this is completed it may be possible to force a plug similar to what a plumber would use to test his lines in the end of the pipe that is spewing the oil which will force the Oil and pressure back in to the newly tapped line/lines. I would recommend installing 2 or more to the extent where you have tapped openings 2X times the diameter of the pipe to make it easier to force the plug into the open line.
There also seems to be 2 or more ruptures in the pipe as well that are spewing between the BOV and the end of the line it may be possible to use over sized Hot Tap saddles with gaskets built in that would wrap around the pipe. The saddles have openings that are flanged and could act as service openings to accept a valve and or piping to the surface as well.
http://www.tappingsaddles.com/
With out knowing the over all integrity of the pipe that is obviously damaged and compromised I would recommend piping to the surface as until proper assessments can be made as to whether or not the pressure can be shut down all at once as to not cause worse blowouts and ruptures and until the secondary relief well can be drilled and properly secured. If anyone would like to discuss my ideas I am more than willing to discuss what i have recommended in further detail I to like other people would like to see this situation brought under control.
My email is tgrady6060 at yahoo dot com I can direct anyone to the materials and equipment via web sites for further review and evaluation. God Bless America

I suggest a thermonuclear explosion directly on top of the leak. It will collapse the sea floor and the leaking pipe and fuse the sea floor into glass stopping the leak. The great depth and pressure will contain much of the radioactive debris.

My idea is so simple. It may have been submitted.
Cut bent pipe or bolts on flange on top of manifold to get plumb surface.Weld large heavy plate to tube or pipe that will slide down as far as posible inside riser. On top of plate weld 6 inch dia pipe. Slide very heavy objects with hole to slide over 6 inch pipe to sit on top of plate. Keep adding weights until plate sits on top of riser. you might need to put rubber under plate to seal on top of riser

Here is an idea…
Forget about capping the pipe or stopping the spill… Build a rubber/vinyl funnel and stake it to the ocean floor let the oil fill it and use the oil right out of the funnel. It would need to be separated from water but then just refine the stuff and use it… The bad part is that you would not be able to work on the pipe, BOP, or anything until the pressure is reduced to zero and no more oil is coming out under pressure but so what…

I am thinking the same thing only dropping a long expandable plug in first and using the wieghts to hold in down. I heard they needed 400 tons of force. I am thinking they may not want to cap this off entirily as to not cause a well head failure or an explosion. But I think you have the right idea.

I submitted plate idea about plate with a lot of weight on the top of plate. Do anyone know what the diam of the pipe is just below the top flange of manifold. my idea would work if you can slide a pipe down far enough into the manifold. You dont have to cap it with my idea. You can have opening in plate with 6 or 8 inch pipe up to 20 foot long welded over the opening and threaded on top with a coupling. Slide a lot of weights over pipe to rest on plate above manifold.On threaded coupling you can install more threaded pipe, a valve or a quick connect coupling. If you can get a pipe down inside manifold this idea would work. Engineers can tweak it but the basic idea has to work.

Utilize the strength of pipe flange on riser. Much like those jaws that were used to cut pipes create one to close and lock around and beneath the flange. On this jaw/clamp around riser hinge to it a valve that can withstand high pressure, maybe a gate valve with the valve wheel on the side. Once the Jaw/clamp is around the riser and secured tightly, swing valve upright onto riser with valve open. Pin down valve with bolts or self locking snaps that will ingage upon swinging valve upright. When valve is in place and secured, use under water robots to close gate valve to hopefully contain the oil and or either stop leak or slow it long enough to drill out new well holes to plug it permanently or use to ease the preasure on leaking riser. The pipe that is extending from riser will need to be removed at the riser. I can not see if there are bolts holding the pipe together to flange but if so cut bolts to leave a free and clear flat flange for which to have a nice even surface which to attach valve.
By all common sense this stands a chance to work but I do realize the complications of the problem being a mile deep in water.

This is not a permanent fix but might work until one is developed. I’m not a scientist but I know oil and water aren’t supposed to
mix so…maybe oxygen (air) could be pumped down to the leak sight in a quantity that would allow the oil/air mix to be ignited and burned before arriving at the Gulf surface . SMOKE BEATS GLOP.

Using Marine Drilling risers to control the physical properties of Hydro-stasis, the pressure of the source is reduced. The solution is the same as the process of Oil extraction, with modifications to the Drill Casing; allowing the release of excess pressure from the Wellhead. Warming the “Bell”, reduces the formation of Hydrates. Controlling buoyancy of the “Bell” is paramount to correct positioning; achieved using Ingots and a Gasoline filled Ballast. The Perforated Casing is positioned into the “Bell” before placement in the water, or it can be lowered over the casing to create a sealing “Flange” where the two meet. Once in place, the Oil pressure will create a “locked” position for the two parts. The Casing is lowered to the wellhead, then anchored to the Seafloor. The Outer Casing then acts as a “sleeve” around the Marine Drilling Riser that contains the “String”, or Drilling Mud. As the Oil pressure increases, it flows out of the perforations and allows for the volumetric pressure to be gradually decreased by pulling the “String”. Remaining Inner Casing and Marine Drilling Riser is then slid down to the wellhead through the bell, completely stopping the oil from leaking out of the perforations
Equipment Needed:
4 Oil Tankers or Tugboats, 4 Mid-casing Relief Valves. 4 – 1400m Tethers if a Tension Leg platform is used. 1200m of Tethers for Ship’s connection to Oil Platform. 4 underwater Oil Platform Pontoon propulsion systems. A Semi-Submersible Petroleum Drilling Platform (Preferably Tension Leg). Ballast.
Materials Needed:
Approximately 1400m. (94 lengths) of Marine Drilling Riser.
1000 meters of Perforated “Outer” Casing. 1400m of “Inner” Casing.
1 Massive Containment Bell (Steel); fitted with pressure and temperature-resistant circulators for Warming System. 3-km. Pressure and temperature-resistant Tubing for Warming System. Gasoline. Anti-Freeze. Drilling Mud. 4 Tension Leg Anchors.

Instead of capping, I think it should be contained. Lets face it we need the oil.
I propose building 20 foot diameter by 100 foot or more concrete pipes like drain or storm water pipes and stacking them on top of each other until a height is reached that will counter the pressure then the oil can be safely piped or pumped to tankers.
If the pipes where built with 5,000 pound concrete the molds could be poured and torn down every couple of days.
if 100 foot long lengths where used it would only take around 50 to reach the surface. The pipe could be stabilized using guide wires much like an antenna tower.
If the pipes need to be fabricated on shore, they could simply be capped on one end and floated into position in an upright fashion using a Collapsible inflated bloater could be fashioned to control the decent and placement
