Studies Show Wind Power’s Massive Potential (Inside Science via 3 Quarks Daily

There is enough energy for people to reap from the wind to meet all of the world’s power demands without radically altering the planet’s climate, according to two independent teams of scientists.

This Is How Facebook Is Tracking Your Internet Activity (Business Insider)

Facebook really is watching your every move online.

In testing out a new diagnostic tool called Abine DNT+, we noticed that Facebook has more than 200 “trackers” watching our internet activity.

Abine defines trackers as “a request that a webpage tries to make your browser perform that will share information intended to record, profile, or share your online activity.” The trackers come in the shape of cookies, Javascript, 1-pixel beacons, and Iframes.

For example, cookies are tiny bits of software that web pages drop onto your device that identify you anonymously but nonetheless signal useful behavior about your background interests to advertisers who might want to target you. Facebook uses these types of cookies to activate the “like” buttons on other websites.

Critics call this spying. Advertisers call it targeting.

What you get is Lit Motors‘ C-1, the world’s first gyroscopically stabilized, two-wheeled all-electric vehicle, which launched at TechCrunch Disrupt in San Francisco today, writes Peter Ha on TechCrunch. Oh, and it will talk to your smartphone and the cloud.
