An Autonomous Sailing Robot To Clean Up Oil Spills
rDouglass writes "Protei is a low-cost, open-source oil collecting robot that autonomously sails upwind, intercepting oil sheens going downwind. This crowd sourced, open source hardware, collaboratively developed project could help prevent the tragedy of the next oil spill. Furthermore, it is a prime example of what people can do together when they collaborate, working together on the research and development, design, and funding. Licensed under the Open Source Hardware (OSHW) license guarantees that as many people in all parts of the world will benefit from this effort as possible."

But-why?
I pledged $150 to this project and look forward to wearing the Protei hoodie that they'll send me. I couldn't believe that it hadn't gotten more attention. I'm not affiliated with the project in any way, but I know that I'm going to weep with bitter joy when I see one of these skimming oil from an oil spill. I hated the feelings of helplessness and desperation that I hada when watching the tragedy of the Gulf spill. Supporting this project at least gives me something concrete to do which just may one day help keep our oceans clean.

It's like an infinite number of monkeys on typewriters collaborated by working together to crowd source this open-source summary.
I think simply mentioning OSHW once is sufficient for the slashdot crowd, considering our familiarity with the topic.
Haven't we learned by now not to call any sort of seafaring vessel unsinkable?
The slick on the surface isn't "the tragedy" of these oil spills. Most of the tragedy is below the surface, where TV cameras and congressmembers won't see it.
I welcome anything good at cleaning up our messes. Especially a device this open and energy efficient. But let's not pretend that cleaning up the surface could possibly "prevent the tragedy". By the time this thing is out there cleaning up, most of the tragedy has already gone down. And pretending it's OK is exactly what the oil drilling biz depends on people thinking so the oil drillers don't have to invest anything in actually preventing the next tragedy.

Unless oil drillers are required by law to pay someone for devices like this one. In that case, there'll be lots of people making them in quantity, especially without the intellectual "property" obstacles and costs.
And if they're not required by law, it doesn't matter how closed or proprietary they are: oil driller will never spend a cent on them, no matter in whose interests (including their own) it would be.

Oh. Nevar mind.
... could help prevent the tragedy of the next oil spill.
Prevent the tragedy of the next oil spill? How about forcing anyone who owns and operates an offshore oil rig or tanker to learn some booming? How about forcing them to have teams of boomers on standby? This project might be good for last stage cleanup, but it does not negate the need for proper spill containment.

It looks like it discharges cleaner water into the ocean. That might make it illegal in the US, due to some bizarre interpretation of EPA regulations.
I was reading that European and Middle-East cleanup ships were turned away from helping with cleanup. This was due to their principle of operation - they would skim muck from the surface, separate the oil and water, and discharge the water back into the ocean, keeping the oil in a holding tank. The problem is that they didn't clean the water they discharged up to EPA standards. Cleanup ships were required to store the mostly-clean water they would otherwise discharge, which means they would have to make frequent trips to dump their tanks.
This is of course absurd, since a ship that takes in a 50% oil solution and outputs a 0.1% oil solution can operate indefinitely and only make things better. The regulation was meant to apply to devices that prevent oil spills in the first place (dumping nothing into a clean ocean is better than dumping 0.1% oil solution).
Utterly amazing. Clearly regulation is necessary (otherwise there is no incentive to not pollute in the first place), but such strict application of law is something right out of Kefka or Wikipedia... :)
Why use wind power when there's all that juicy oil floating around??
Mentioned in TFA but not the summary, is the idea that these could be deployed to work on the plastic fragments floating around in the pacific gyre. Don't know if the scope is feasible, but it's fairly original and more scalable than any other approach I've heard of.
Also, they've developed an articulating hull to deal with drag of a long tail--it's rather original. They're up front about not yet knowing howing it'll behave when the tail accumulates a full load of oil. That's why they're raising money for the next version (#6).
Remain calm! All is well!
But will it still have trouble finding home base to recharge?!
They want tens of thousands of dollars to make a prototype that will be "low cost"? This isn't a story about something that has been actually made. How much is actually required to make a autonomous boat? Well, I guess I know a little more than most, since I've actually built a prototype - the budget needed for all the parts easily comes in under $3000.

The "Open Boat" project is intended as a research platform; eventually to permit long term sea going boats to perform research such as weather monitoring. It is also the first step towards investigating autonomous cargo vessels. All the software is open source, and currently running on a Linux based ARM.
Last summer, when the oil geyser had been flowing uninhibited for over two months, I posted here about my idea for using the US Navy's portable nuclear reactors to power air pumps that would oxygenate ocean waters affected by the spill. The oxygen would feed the bacteria already present in the water that happily consume seeped oil.
The slick on the surface isn't "the tragedy" of these oil spills. Most of the tragedy is below the surface, where TV cameras and congressmembers won't see it.
One of the visitors said that it'd be difficult to pump air to the depths of the ocean, and suggested pumping oxygenated surface water instead. I took that and other feedback to write a short followup piece on Cleaning up the Gulf of Mexico.
I welcome anything good at cleaning up our messes. Especially a device this open and energy efficient. But let's not pretend that cleaning up the surface could possibly "prevent the tragedy". By the time this thing is out there cleaning up, most of the tragedy has already gone down.
While this thing might be okay for little oil spills, like the one from a few weeks ago, effectively responding to future underwater blowouts will require massive infrastructure and power. Like what could be stored on, delivered and powered by a retired nuclear-powered aircraft carrier.
I just want the politicians to order the Navy to get some guys thinking about the idea: When Disaster Strikes, Send the Enterprise. Or maybe I'll write the Japanese embassy to suggest that they offer to buy the Enterprise, thereby saving the US Navy $millions in decommissioning costs. They have the infrastructure to refuel it, if required, and the motivation to dedicate it to disaster response.

If you sailed through it, there's a decent chance you wouldn't notice it, as it is composed of small, widely dispersed particles. Which is just the size for pieces of plastic to cause problems for a lot of hungry sea life.
Devices (perhaps less energy efficient and certainly not as automated) like this already exist and were available during the oil spill crisis. The Dutch offered to loan some of their skimmer boats to the US early in the crisis. The US turned them down as not being efficient enough (<sarcasm>obviously, it's better to let the spill keep growing rather than skim out a mere 98% of the oil</sarcasm>). Once the spill had already spread, the US government then granted a waiver to allow the Dutch ships to be used.
The article doesn't touch on the question of whether or not these particular devices would meet US environmental requirements. Even if they existed, it's not clear that the US government would have allowed them to be used in the early days of the crisis.
Note that the delay made the existing devices less effective in a couple ways. First, they reduced the amount of time the skimmers could be used before the oil became too diffuse. Second, they would have been most effective at the beginning of the crisis when the oil was at its most localized. When working in an area that is 50% oil, it doesn't matter as much that they leave 2% contamination (or whatever the actual number is; I can't find a citation for the actual efficiency at the moment). That's still a removal of 96% of the oil. However, if there is only 4% oil, then leaving 2% is leaving 50% of the oil that was present.
