As with previous X PRIZE competitions, this one was intended to encourage private sector scientific research, by offering a cash prize to whichever team could best meet a given challenge. In this case, teams had to demonstrate a system of their own making, that could recover oil from a sea water surface at the highest Oil Recovery Rate (ORR) above 2,500 US gallons (9,463.5 liters) per minute, with an Oil Recovery Efficiency (ORE) of greater than 70 percent.

While some called it a publicity stunt, it was the first time that a commercial airliner had flown using biofuel – albeit only in part of one of its four fuel tanks. Today, however, the airline announced that it’s developing an aviation fuel that will have half the carbon footprint of conventional fuel. The carbon savings won’t result from how cleanly the fuel burns, but from how it’s obtained. <a href="/web/20111013135653/http://www.gizmag.com/virgin-airways-low-carbon-jet-fuel/20126/">Read More</a> </p> </div> </div> <div class="summary_item "> <div class="summary_details"> <div class="sd_top"> <a class="small" href="/web/20111013135653/http://www.gizmag.com/onthewater/" style="float: left; ">ON THE WATER</a> </div> <div class="clear_both"> <h2><a href="/web/20111013135653/http://www.gizmag.com/bacteria-barnacles-anti-fouling-ships/20062/">Bacterial byproduct keeps barnacles from clinging to ships' hulls</a></h2> <div class="summary_details_left"> <p>By <a href="/web/20111013135653/http://www.gizmag.com/author/ben-coxworth/">Ben Coxworth</a></p> <p><em>19:13 October 5, 2011</em></p> </div> <div class="summary_details_right"> <p><img src="/web/20111013135653im_/http://www.gizmag.com/images/icons/splashyIcons/comments.png" alt=""/> <a href="/web/20111013135653/http://www.gizmag.com/bacteria-barnacles-anti-fouling-ships/20062/#comments">1 Comment</a> </p> <p></p> </div> </div> </div> <center><a class="noback" href="/web/20111013135653/http://www.gizmag.com/bacteria-barnacles-anti-fouling-ships/20062/"><img src="https://web.archive.org/web/20111013135653im_/http://images.gizmag.com/hero/barnaclehulls-1.jpg" title="The hull of a boat that was painted with a coating containing macrocyclic lactones, with t..." alt="The hull of a boat that was painted with a coating containing macrocyclic lactones, with t..."/></a></center> <div class="summary"> <p>While the sight of barnacles on ships' hulls may seem like a very normal part of the maritime environment, the fact is that the presence of such organisms makes a vessel much less streamlined. The harder it is for a ship to slice through the water, the harder its engines have to work and the more fuel it uses. Although there are some anti-fouling coatings that can be applied to hulls, these are often toxic, and can leach into the surrounding water and harm marine organisms.

Many of these sponge-like filters incorporate porous crystals known as metal-organic frameworks (MOFs). Unfortunately, most MOFs are derived from crude oil, plus some of them contain toxic heavy metals. Researchers from Illinois’ Northwestern University, however, recently announced that their <em>nontoxic</em> MOF sponge – made from sugar, salt and alcohol – is fully capable of capturing and storing CO2.

Among other things, they claim that the caged fish release too much concentrated waste into the surrounding waters, too many antibiotics and anti-algal chemicals are used, the ecological balance is upset when non-native fish escape from their pens, and strain is put on populations of local fish that are captured for use in feed for carnivorous farmed fish. Unfortunately, wild-fish-capturing methods such as drift net fishing and bottom trawling have big problems of their own. A new system that involves raising fish in mesh spheres that float in the open ocean, however, is claimed to sidestep many of the drawbacks of traditional marine aquaculture. The Velella Research Project is pioneering the technology. <a href="/web/20111013135653/http://www.gizmag.com/velella-research-project-fish-farming/19857/">Read More</a> </p> </div> </div> <div class="summary_item "> <div class="summary_details"> <div class="sd_top"> <a class="small" href="/web/20111013135653/http://www.gizmag.com/aroundthehome/" style="float: left; ">AROUND THE HOME</a> </div> <div class="clear_both"> <h2><a href="/web/20111013135653/http://www.gizmag.com/miele-solar-heated-dryer/19680/">Miele to release solar-heated clothes dryer</a></h2> <div class="summary_details_left"> <p>By <a href="/web/20111013135653/http://www.gizmag.com/author/ben-coxworth/">Ben Coxworth</a></p> <p><em>07:41 September 2, 2011</em></p> </div> <div class="summary_details_right"> <p><img src="/web/20111013135653im_/http://www.gizmag.com/images/icons/splashyIcons/comments.png" alt=""/> <a href="/web/20111013135653/http://www.gizmag.com/miele-solar-heated-dryer/19680/#comments">8 Comments</a> </p> <p><img src="/web/20111013135653im_/http://www.gizmag.com/images/icons/splashyIcons/image_modernist.png" alt=""/> <a href="/web/20111013135653/http://www.gizmag.com/miele-solar-heated-dryer/19680/picture/141420/">3 Pictures</a></p> </div> </div> </div> <center><a class="noback" href="/web/20111013135653/http://www.gizmag.com/miele-solar-heated-dryer/19680/"><img src="https://web.archive.org/web/20111013135653im_/http://images.gizmag.com/hero/miele-solar-heateddryer-0.JPG" title="Miele's latest dryer utilizes heat gathered by rooftop solar-thermal collectors" alt="Miele's latest dryer utilizes heat gathered by rooftop solar-thermal collectors"/></a></center> <div class="summary"> <p>At last year's IFA electronics trade show, Miele unveiled its <a href="https://web.archive.org/web/20111013135653/http://www.gizmag.com/miele-washing-machinet-knows-when-electricity-is-cheap/16203/" target="_blank">SmartGrid-ready washer and dryer</a>.

While it’s definitely a good thing that such is no longer the case (for the most part, at least), there’s still the small matter of what happens to the bagged excrement once it’s thrown away. Conventional bags keep it sealed inside, perhaps so that future archeologists can marvel at it when digging through our landfills. Even biodegradable bags take a long time to break down under certain conditions, and leave landfills full of untreated feces. Flush Puppies flushable doodie bags, however, reportedly allow dog poop to be flushed down the toilet, so it can be treated in a municipal sewage system. <a href="/web/20111013135653/http://www.gizmag.com/flush-puppies-flushable-dog-poop-bags/19458/">Read More</a> </p> </div> </div> <div class="summary_item "> <div class="summary_details"> <div class="sd_top"> <a class="small" href="/web/20111013135653/http://www.gizmag.com/ecogizmo/" style="float: left; ">ECOGIZMO</a> </div> <div class="clear_both"> <h2><a href="/web/20111013135653/http://www.gizmag.com/smart-fishing-hook-repels-sharks/19406/">Electromagnetic fish hook reduces accidental shark catches</a></h2> <div class="summary_details_left"> <p>By <a href="/web/20111013135653/http://www.gizmag.com/author/ben-coxworth/">Ben Coxworth</a></p> <p><em>13:35 August 2, 2011</em></p> </div> <div class="summary_details_right"> <p><img src="/web/20111013135653im_/http://www.gizmag.com/images/icons/splashyIcons/comments.png" alt=""/> <a href="/web/20111013135653/http://www.gizmag.com/smart-fishing-hook-repels-sharks/19406/#comments">2 Comments</a> </p> <p></p> </div> </div> </div> <center><a class="noback" href="/web/20111013135653/http://www.gizmag.com/smart-fishing-hook-repels-sharks/19406/"><img src="https://web.archive.org/web/20111013135653im_/http://images.gizmag.com/hero/smarthook.jpg" title="The SMART Hook is said to reduce unintended shark catches " alt="The SMART Hook is said to reduce unintended shark catches "/></a></center> <div class="summary"> <p>In fisheries all over the world, many fish are caught using a process known as pelagic longlining. This consists of fishing crews traveling out into the open ocean and deploying a series of baited hooks that are all attached to one horizontal main line, that can range from 20 to 40 miles (32 to 64 km) in length. After being left to sit in the water for a period of time, the line is hauled abroad a fishing vessel, where the fishes that took the bait are removed from the hooks. Unfortunately, even though they're not usually one of the targeted species, sometimes sharks will be among the fish captured. A new type of fish hook, however, is said to reduce unintended shark catches by up to 94 percent. <a href="/web/20111013135653/http://www.gizmag.com/smart-fishing-hook-repels-sharks/19406/">Read More</a> </p> </div> </div> <center class="snap_noshots"> <div class="next_prev"><strong> <span>1</span> <a href="/web/20111013135653/http://www.gizmag.com/tag/eco-friendly/2/">2</a> <a href="/web/20111013135653/http://www.gizmag.com/tag/eco-friendly/3/">3</a> <a href="/web/20111013135653/http://www.gizmag.com/tag/eco-friendly/4/">4</a> <a href="/web/20111013135653/http://www.gizmag.com/tag/eco-friendly/5/">5</a> <a href="/web/20111013135653/http://www.gizmag.com/tag/eco-friendly/2/">Next </a> » </strong></div> </center> <div class="dotsontop">  <div id="search_form_bottom"> <form action="https://web.archive.org/web/20111013135653/http://www.gizmag.com/search/" id="cse-search-box-bottom"> <span class="title">Looking for something?
