Use of biofuel could reduce aviation-related emissions

But burning biofuel still gives off a lot of soot particles.

Emissions from aviation often result in jet trails, a specific type of cloud formation. These clouds can influence climate through alteration of water vapor and heat retention due to how they reflect radiation. Jet emissions also contain aerosol particles that can influence atmospheric behavior. Direct emissions of carbon dioxide also influence the climate. For all these reasons, governments are considering ways to curb aviation-related emissions.

Recently, a team of researchers has investigated the impact of biofuels on aviation emissions. Sustainable bio jet fuels offer a potential route to offsetting greenhouse gas emissions, but issues of cost and sustainability continue to hamper biofuels' widespread adoption. Use of bio jet fuels also offers other advantages, including a potential reduction in harmful emissions due to near-zero levels of sulfur and aromatic chemicals common in petroleum-based jet fuels. These types of emissions are particularly problematic because they can induce further cloud formation.

Cruise condition evaluation of jet engine exhaust

The studies were conducted using NASA DC-8 turbofan engines on flights originating at NASA's Armstrong Flight Research Center in Palmdale, California. The aircraft contained four wing-mounted engines that could be fed fuel separately. The researchers took measurements of jet engine exhaust at cruise conditions when burning either a blended biofuel or a conventional petroleum jet fuel. The petroleum jet fuels explored were either medium- or low-sulfur Jet A fuel. The biofuel was an approximately 50:50 volume blend of low-sulfur content Jet A fuel and a Camelina-based EFA biojet fuel.

Getty Images Slams Google For Seeking Copyright Safe Harbor

The proposed introduction of a ‘safe harbor’ provision to Australian copyright law is producing yet more conflict today, with Getty Images accusing Google of promoting piracy. The image library says providers like Google “do nothing” to detect or prevent copyright infringement and that safe harbors actually encourage them to turn a blind eye.

The notion that online platforms should not be held responsible for the infringing acts of their users is something entrenched in law in many regions, including the United States and Europe.

In Australia, however, a perceived drafting error in the implementation of the Australia – US Free Trade Agreement (AUSFTA) means that safe harbor provisions only apply to commercial Internet service providers.

As a result, Google, Facebook, YouTube and similar platforms face copyright uncertainty, a tenuous position also suffered by schools, universities, museums, libraries and archives.

If proposed amendments to the Copyright Act are adopted, all of the above will receive enhanced safe harbor protections and the country into be brought into compliance with AUSFTA. Instead, however, battle lines are being drawn, with technology companies on one side and heavily copyright-reliant entities on the other.

Today it’s the turn of Getty Images to throw its hat into the ring. Getty has been embroiled in dozens of copyright lawsuits in its history so is well aware of the difficulties its business can encounter. It’s also strongly against safe harbors that would allow companies like Google to use its images in search results, for example, without having to shoulder any liability.

Speaking with The Australian (paywall), Getty Images’ general counsel Yoko Miyashita says that safe harbors have been ruthlessly exploited by online platforms and actually make it harder for copyright holders to protect their rights.

“Here in the US the safe harbors were intended to provide strong incentives for online ­service providers and copyright holders to co-operate to detect and deal with copyright infringements … but that has never materialized,” Miyashita says.

“There is no incentive for co-operation. The safe harbors are instead used by service providers as a shield and an excuse for doing nothing to detect or prevent copyright infringement.”

When service providers become aware that their platforms are being used for infringement in a specific case, it’s argued that they are required to take remedial action to bring them into compliance and maintain their safe harbor protections.

But for the Getty general counsel, all this does is force technology platforms to look even further in the opposite direction to avoid knowledge, rather than getting sucked into a copyright minefield. Becoming involved in steps to prevent piracy can even mean they become further exposed.

“In fact, we have seen that ­service providers risk greater ­liability if they take steps to detect and prevent infringements, so they are encouraged to stick their head in the sand,” Miyashita said.

While the music, movie and TV show companies have their specific complaints against Google, Getty Images feels it is particularly exposed by the search giant’s actions. While movies and TV shows are largely streamed or downloaded from third-party sites to which Google merely links, Getty’s images appear in results themselves, ready to be shared with others with a couple of clicks.

Results can be taken down of course, but the onus lies with copyright holders to take action in each and every case, something which sees Google process millions of takedown notices every week.

“Each of those reports represents an instance where copyright holders were not com­pensated for use of their works,” Miyashita notes.

“This shows not only the burden on copyright holders to identify infringements and prepare and send notices…but also the lack of respect for copyright which has been fuelled in large part by the safe harbors.”

That Getty Images should single out Google in the safe harbor debate comes as no surprise, as the companies rarely see eye to eye when it comes to the use of Getty’s images.

Last year the stock photograph outfit filed a complaint with the European Union’s antitrust commission, claiming that Google is engaged in piracy of its content. Getty told the EU that Google undermines its business by utilizing Getty stock images in a manner that “siphons traffic” away from the Getty’s own website.

Considering that safe harbor provisions are standard across Europe and the United States, the battle underway in Australia is something of an anomaly.

That being said, the fact that Australia-based technology companies are now being forced to fight entertainment and heavily copyright-dependent industries to achieve their goals is nothing new and is only likely to drive the parties apart – or investment away.

At the moment the momentum is in favor of safe harbor introduction, but things are only just getting heated up and are far from over.

Demonoid Returns After Two Months Downtime

After nearly two months of downtime, the semi-private BitTorrent tracker Demonoid resurfaced online this weekend. The site was pulled offline due to hosting problems and had to endure some internal struggles as well, but barring a few bugs, it’s now back in action.

demonoid-logoWe’ve written the phrase “Demonoid is Back” quite a few times already on TorrentFreak.

The site has established a reputation as the “comeback kid” due to its ‘habit’ of going offline for weeks or even months, and then reappearing in its full glory as if nothing ever happened.

Over the past several weeks, the site has been offline once again. Late January the site went down due to hosting and some internal problems and was forced to remain offline longer than expected.

According to Deimos, the site’s founder, there was some disagreement with the person who handled most of the technical aspects of the tracker. After both sides failed to reach an agreement, he saw no other option than to take control again.

“I gave control to the wrong guys while the problems started, but it’s time to control stuff again,” Deimos told us earlier.

This weekend the site came back online and it’s currently accessible through Demonoid.pw as well as the Dnoid.me domain name. The site is running on new hardware, and there may still be a few bugs, but otherwise it’s fully operational.

TorrentFreak reached out to Deimos this weekend, who informed us that the site was restored from a recent database backup. So, everyone should be able to access his or her old account as usual.

In an update posted on the site, Demonoid’s operator is also surprisingly open about what happened, mentioning the aforementioned internal problems and personal issues as a reason for the prolonged downtime.

“After some long downtime caused mainly due to some problems with some of the people we made the mistake of trusting, and some personal problems regarding the health of a family member that drained the time and money destined to move the site elsewhere, we are finally back with you,” the update reads.

Now that the site is back, it’s clear that one of the oldest BitTorrent communities will live on. But who would have expected anything different from the comeback kid?
