Optimizing Thermoelectric Energy Generation

By Elizabeth Montalbano – Deriving energy from the heat electronic devices emit so they can provide their own sustainable sources of power is a Holy Grail for scientists developing power sources for sensors that will drive the future of healthcare devices as well as the Internet of Things.

Researchers in Japan now have come up with a new thermoelectric generator that can convert temperature differences to electricity can be used to power small, flexible devices.

Scientists at Osaka University developed the device in the form of a bismuth telluride semiconductor on a thin, polymer film that weighs less than a paperclip and smaller than the size of an adult fingernail.

However, packed in the tiny device is a maximum output power density of 185 milliwatts per square centimeter, which “meets standard specifications for portable and wearable sensors,” Tohru Sugahara, an associate professor at the university’s Institute of Scientific and Industrial Research, in a press statement. more>

The internet of (economic) things

By Jonathan Sallet – Robert Gordon argues that, with the exception of a decade starting in the mid-1990s, information networks have not driven productivity in the way that electricity transformed the American manufacturing sector in the 20th Century. But some believe now that IoT (internet of things) can boost productivity growth by increasing the efficiency of traditional business operations such as manufacturing, transportation, and retail. Whether the United States can return to historical productivity growth levels is critical to the American economy.

IoT standards raise a series of policy questions: Are industry standards being set in a pro-competitive fashion?

Are companies complying with their obligations under standards (a question featured in an analogous context in the recent Federal Trade Commission complaint against Qualcomm)?

And what kind of role should government play in establishing the standards at the outset? more>

How a botnet works: 1. A botnet operator sends out viruses or worms, infecting ordinary users’ computers, whose payload is a malicious application €” the bot. 2. The bot on the infected PC logs into a particular command and control (C&C) server (often an IRC server, but, in some cases a web server). 3. A spammer purchases access to the botnet from the operator. 4. The spammer sends instructions via the IRC server to the infected PCs, causing them to send out spam messages to mail servers.

By Joe Stanganelli – Recent headlines have been rife with examples of security backdoors allowing hackers to take control of all manner of smart devices, including televisions, baby monitors, pacemakers, and cars.

IoT vulnerabilities transcend the consumer market, however, and the enterprise should be concerned. Industrial control systems increasingly deploy IoT technology. Many companies are already operating from energy-efficient smart buildings managed by city-wide smart grids and furbished with smart thermostats, smart lighting systems, smart emergency alarms, and smart whatever-else-you-can-think-of. more> http://tinyurl.com/oop9wzw
