Solar Panels has been improve with virus

Viruses can help build better solar panels that capture and process more efficient solar energy into electrical energy. This has been demonstrated at a Research Massachusetts Institute of Technology (MIT for its acronym in English) that has used a type of virus to restructure the carbon nanotube solar panels and increase their efficiency by 30 percent, from 8 to 10 , 6 per cent.

That the efficiency of solar panels is still well below their potential is more than evident. What was not known so far is that something so small and is sometimes dangerous as a virus, could hold the key.

The virus called M13 coordinate gets rolled carbon nanotubes in graphene that make solar cells so that the electron transport more efficient and therefore produce more electricity. Basically, the M13 gets the two types of nanotubes (semiconductors and cables) that form the structure of solar cells, do not interfere with each other and impede the flow of electrons, but the structure becomes smooth.

Grätzel cells
Each virus controls between five and ten nanotubes, using about 300 proteins. In addition, viruses have been genetically modified to produce a layer of titanium dioxide, a key component in Grätzel cells, a type of structure they use this compound to improve electron transport.

Xiangnan Hyunjung Yi Dang, MIT students along with Professor Angela Belcher successfully tested this new virus in Grätzel cells, but explained that the technique could also be used for other types of solar cells, including organic.

The virus also solubilized nanotubes making them easier to incorporate the solar panels at room temperature, significantly reducing the manufacturing cost.

Movies on YouTube after a deal with Sony and Universal

The streaming video service YouTube would be close to allow users to watch movies on your site. Some of the largest companies in the industry, such as Sony Pictures Entertainment, Warner Brothers and Universal, will lend their productions for this project, which could begin this week or next.

The movie industry is finding new ways to distribute their content and prevent piracy affecting this sector. There are several initiatives in this regard, as the service offered by Apple and Netflix, a company with a strong position right now in the online video market. Even Facebook has reached an agreement with Warner to rent movies through the network.

However, the most visited site in streaming video on the Internet, YouTube, I still had some way to go, take some time despite offering movie rentals through its site. Now it seems that the platform gathers momentum in this market. According to information published in The Wrap, the Google website has reached agreements with Sony Pictures Entertainment, Warner Brothers and Universal to offer access to their productions.

Apart from these big companies, YouTube would have signed other agreements with more independent producers such as Lionsgate and Kino Lorber, sources close to the negotiations. In this way the site would be ready to launch its movie rental service this week or next.

The agreements will expand the catalog of movies on YouTube, making it a competitive service that can compete with the supply of systems like Apple or Netflix. The great mass of the platform gives users the ability to boost this sector site, supporting a new form of distribution for films.

According to The Wrap, other producers such as Paramount, Fox and Disney have rejected the agreement with YouTube to offer movies through the site. On the other hand, streaming video company has issued a statement after meeting the information published stating "We have been adding more and more titles strongly since we launched the YouTube movie rental for more than a year, and now we have thousands of titles available. Beyond that we do not comment on rumors or speculation. "
Renting movies on YouTube

YouTube videos usually have a short duration. It is a place where you can see larger productions, in fact they tend to be divided into several parts. In fact the platform has never promoted the movie rentals as such.

At present the company has seen the business niche, according to a source close to the deal, manager of one of the producers who signed: "We believe this begins with VOD (video on demand), but will be expanded to include sales over time. We are very excited because we are happy to see new participants in the transaction model rather than a subscription model. "

It is unclear how YouTube will charge for the rental of films, but behind it is a market of 130 million monthly users to monetize the new service.
