Where should NASA engineers be placing more attention in preparing for future space activities? A committee of the National Research Council studied the question and came up with six technological areas for which additional R&D "should be prioritized." The areas include: 1)tools for mining resources from the moon, Mars, or other planets, with the focus on extraction, processing, and storage methods; 2)high-frequency, wideband interplanetary communications systems with reduced weight, power requirements, and costs; 3)microelectromechanical systems for use in spacecraft sensors, communications, navigation, power, and propulsion; 4)safer nuclear power systems with improved energy-conversion efficiency for deep-space missions; 5)radiation-resistant computer memories and electronics through lightweight shielding, protective materials, and data-recovery methods; and 6)precisely controlled antennas, mirrors, and other space structures needed to develop giant space radars and telescopes. The committee says NASA should ensure that much of the research it funds in these six technology areas be conducted through private firms and universities. In the next three to five years, the report adds, NASA should reassess whether the areas should continue to be developed or whether other fields hold more promise.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
