Boeing's two-year study of jatropha-curcas agriculture in Brazil has found that location choice and strong seeds are the key to maximizing the crop's benefits, the company said today.

The jatropha-curcas plant has been under close scrutiny in recent years by scientists and companies because its olives yield an oil that can be made into an alternative jet fuel. The weedy plant can grow in adverse soil conditions. And in addition to yielding oil, it provides, like most plants, the secondary benefit of removing carbon from the atmosphere. Many have been trying to compare the carbon footprint of producing … Read more

People will significantly conserve electricity during peak demand if given price incentives and tools to modify usage, according to a new study.

Apple's iPad still reigns supreme among tablets, but its grip on the market is starting to loosen.

In the fourth quarter, Apple's tablet captured 75.3 percent of worldwide market share, easily besting Android-based devices' 21.6 percent share, according to market-research firm Strategy Analytics. However, those figures differ vastly from the third quarter when Apple had 95.5 percent share and Android had just 2.3 percent.

For 2010 overall, iPad's held 84.1 percent of the market, while Android devices accounted for 13.1 percent.

Despite the iPad's slip, Apple sold millions more in … Read more

Scientists from Stanford University and the University of California at Davis have crunched the numbers and come up with a plan for how the world might economically and feasibly make the move to renewable energy in the next 20 to 40 years.

In a two-part paper (Part 1 PDF, Part 2 PDF) published in the journal Energy Policy, Mark Z. Jacobson and Mark A. Delucchi show in great detail the who, what, where, and how of implementing a renewable energy-run world. It includes solutions to economic, material, and transport issues.

Jacobson, an atmospheric scientist and professor of civil and environmental … Read more

Both Amazon and Barnes & Noble don't report sales figures for their respective e-readers, the Nook and Kindle. But one company, Crimson Hexagon, has taken it upon itself to formulate some opinions about the e-reader market by charting and analyzing Twitter conversations for both the Nook and Kindle, as well as the iPad as an e-reader.

This is one of the studies you probably have to take with a grain of salt because there are some mixed messages in the report. For starters, the title of Crimson Hexagon's blog post for the study is, "Nook emerges as … Read more

LCD TV shipments will rise this year, but that growth won't be as high as it has been over the past few years, market research firm DisplaySearch predicts.

Global LCD TV shipments are expected to rise 13 percent in 2011 to 215 million units, DisplaySearch said Monday. In 2010, LCD TV shipments were up 31 percent compared to 2009, with 190 million units shipped for the year.

Even with more shipments, the LCD TV market's continuing price erosion will cause it to see its "first ever revenue decline," DisplaySearch claims. The researchers didn't say how … Read more

Mobile game revenue is expected to nearly double by 2015, Juniper Research predicted today.

According to the market researcher, mobile game revenue topped $6 billion last year. By 2015, Juniper predicts, that figure will be over $11 billion. However, the research firm noted that as time goes on, a shift will occur with revenue migrating from the "traditional pay-per-download model" to in-game purchases.

Juniper expects that by 2013, more revenue will be generated from in-game purchases than from actual downloads of mobile games. The research firm said "discoverability remains a problem for developers and publishers on some … Read more
