New Technique For Restoring Historic Videos

USC Shoah Foundation has a large collection of interviews with survivors and witnesses of the Holocaust and other genocides. Old physical media formats are susceptible to damage from fires to improper storage and USC has had to deal with this. The tech department at the foundation has figured out a painless way to restore and even improve the quality of footage from the damaged media.

Remembering history and being able to hear first hand accounts of events (no matter how horrific) can only help humanity. If we forget our history we are likely to repeat it.

Ryan Fenton-Strauss, video archive and post-production manager at ITS, was tasked with researching video restoration techniques currently being used in the motion picture industry. He found that there were very few existing options for restoring tape-based material.

â€œIt seemed terribly unfortunate that after a survivor had lived through the Holocaust and poured his or her heart into a testimony, that parts of it would be lost due to a technical problem during the recording process,â€ Fenton-Strauss said.

However, Fenton-Strauss had an epiphany while sorting family photos with Googleâ€™s Picasa tool. He noticed that Picasaâ€™s facial recognition software was so powerful that it could recognize his six-year-old daughter as a baby.

â€œI realized then that if we could automate the process of identifying the “good” and “bad” images using image recognition software, then we could correct some of our most difficult video problems,â€ Fenton-Strauss said.

Wind Becomes Largest Source of Energy in Spain

Spain makes use of a plethora of energy sources and they are leaders in Europe when it comes to utilizing solar and wind energy. Energy policy is always under debate in the country and hopefully they will continue their overall trend of helping sustainable energy develop.

Wind accounted for 20.9 percent of the countryâ€™s energy last year â€” more than any other enough to power about 15.5 million households, with nuclear coming in a very close second at 20.8 percent. Wind energy usage was up over 13 percent from the year before, according to the report.

The news is being hailed by environmental advocates as a sign that Spain, and perhaps the rest of the world, is ready for a future based on renewables. But the record comes at the end of a very rocky year for Spainâ€™s renewable energy sector, which was destabilized by subsidy cutbacks and arguments over how much the government should regulate renewable energy companies.

Despite the flaws in Spainâ€™s system, the numbers are promising for green energy fans. The renewable push brought down Spainâ€™s greenhouse gas emissions by 23 percent, according to another industry report from Red Electric Espana (REE).

4 Theories Why US Teenagers Are Driving Less

Cars are horrible for the environment and car infrastructure can have very negative impact on local economies so it’s nice to see enthusiasm for driving diminishing in younger generations. American teens are less likely to have a license and less likely to want to own a car than previous generations.

Does this mean the end of car culture in the States? Maybe, but for now all we do know is that their lower driving rates are already having an impact on energy policy in the states.

Growth in “vehicle-miles traveled” (VMT)â€”that key gauge of America’s love affair with the automobile that once reliably ratcheted up year after yearâ€”will slow dramatically, the U.S. Energy Information Administration (EIA) says in its new Annual Energy Outlook. The EIA slashed its projected annual VMT growth rate to 0.9 percent, a drop of 25 percent compared to its forecast only a year ago.

The change is partly due to slower population growth, but also because of a generational shift confirmed by at least four studies in the past year. In the United States, young people are not only driving less than teens did a generation ago, they aren’t even getting licenses.

Put that demographic trend together with the dramatic increase in fuel economy expected in the years ahead, and U.S. energy consumption to fuel cars is expected to drop one-quarter to 12.1 quadrillion Btu by 2040.

Using Drones For Studying Ecologies

Drones are popularly associated with American air strikes on civilians and thus have a negative reputation. The technology underlying the drones can be used for good though. One example of a good use of drones is for aerial surveillance of plants and animals in hard to access/expensive areas.

What are our forests really made of? From the air, ecologist Greg Asner uses a spectrometer and high-powered lasers to map nature in meticulous kaleidoscopic 3D detail — what he calls â€œa very high-tech accounting systemâ€ of carbon. In this fascinating talk, Asner gives a clear message: To save our ecosystems, we need more data, gathered in new ways.

China’s Wind Turbine Industry Booming

For years China has been trying to improve its sustainable energy production but to do so Chinese companies had to rely on patents and techniques from the rest of the world. Due to an increase in demand (and production knowledge) China is now poised to make the best, most efficient, and easiest to maintain wind turbines.

Already, the amount of wind energy outputted in China puts the rest of the planet to shame.

However, since China’s total generation is more than that of all European Union countries combined, wind’s percentage is large in absolute terms.

Liming Qiao, China director of the Global Wind Energy Council (GWEC), said: “Two per cent sounds small but it’s not when you consider China’s total electricity.

“In fact, last year wind surpassed nuclear to become number three after coal and hydro, and it’s got a lot more potential.”

The sheer scale of the wind market is encouraging mass production which has lowered prices and fostered innovation.

Until recently, Chinese wind manufacturers produced Western-designed turbines under licence. Some acquired a reputation for turning out inferior products.

Now, the wind boom has led to a flurry of new designs. Goldwind, for example, offers a turbine which does not need a gearbox but instead has a “direct drive” system designed to be cheaper to maintain.
