IMG_6688

Those with an Amazon Echo device in their homes have likely already exposed their children to Alexa. Now, Amazon wants to give kids the opportunity to turn Alexa into their friend with the new Echo Dot Kids Edition. The hockey puck-like smart speaker doesn’t look too different from the original Dot, but it comes with new “Amazon FreeTime” content that gives kids new ways to interact with Alexa and parents more control over those interactions.

New parental controls and FreeTime Unlimited subscription coming soon, too.

U.S. Department of Transportation wants our cars to ‘talk’ to each other

connected-vehicles

Vehicle-to-vehicle communications would report where every car, bus, and truck is, where it’s going, and how fast it’s moving.

The US Department of Transportation (DOT) has announced plans to move forward with vehicle-to-vehicle (V2V) communication systems. After years of experimentation and a real-world trial in Ann Arbor, MI the government is almost ready to make peer-to-peer networking a required safety feature on all new cars.

The DOT: Future Concept Car That Networks With Other Vehicles

The DOT: Future Concept Car That Networks With Other Vehicles

Concept DOT 

Certain design elements of the Concept DOT remind us of the stackable cars concept, and well, it does appear to have functions similar to MIT’s concept as well. The zero emission vehicle moves on three wheels and uses electromagnetic motors to propel itself. While on the road, it is capable of networking with other vehicles, and even allows attaching of similar vehicles. Again, something similar to MITs stackable concept. (Pics)

Quantum Dot Solar Cells to Capture Broader Spectrum of Sunlight

 Quantum Dot Solar Cells to Capture Broader Spectrum of Sunlight

For the first time, researchers have created solar cells made of different-sized quantum dots, each tuned to a specific wavelength of light. By arranging these quantum dots in an ordered pattern, the scientists hope that they can one day fabricate “rainbow” solar cells, which can efficiently harvest a large part of the useful spectrum of sunlight.
