Samsung just threw their hat into the growing LED market by launching a new line of bulbs that can suit practically any lighting need. The line features 7 energy-sipping bulbs that should fit practically any socket in the house. The new bulbs join the ever-expanding options available to shoppers who are looking to save money and get just the right light. Read on for a closer look at these new bulbs, and to learn how they stack up against the competition.

For those unfamiliar with the term, a “whispering gallery” is a round room designed in such a way that sound is carried around its perimeter – this allows a person standing on one side to hear words whispered by a person on the other. Now, scientists from Stanford University have developed a new type of photovoltaic material, that essentially does for sunlight what whispering galleries do for sound. Not only does the material have a structure that circulates light entering it, but it could also result in cheaper, less fragile, and less angle-sensitive solar panels.
Stanford researches may have solved the problem of range anxiety by wireless charging technology that could one day create an electric highway.
Wireless recharging already is used by some electric vehicle charging stations to fill up batteries without cords or plugging into an outlet. MIT helped pioneer this technology and spun it off into a wireless charging startup, WiTricity. However, Stanford researchers improved on this concept and devised a way to transmit 10 kilowatts of electric power across a 6.5-foot distance with minimal energy loss. By overcoming transmitting electricity across a significant distance, researchers will make it possible to pave a highway with wireless conduits that can provide addition power to EVs and let them operate indefinitely.
With large cargo freighters being a major source of CO2 emissions worldwide it’s been encouraging to see various efforts to make such vessels more efficient. In recent years we’ve seen the development of the world’s biggest container ship to cut CO2 emissions per container moved, air bubbles used to cut the friction between a ship’s hull and the ocean, and even plans to return to the use of sails to cut fuel use. Now Nissan has launched an energy efficient coastal car carrier called the Nichio Maru that employs solar panels, LED lighting, a low friction hull coating hull and an electronically controlled diesel engine to cut fuel consumption.
Smartphones of today
The world of cellphones is expanding with new models being launched almost every day. Back in 1973, when the first cellphone was made; it was a bulky object with not many functions other than that of making and receiving calls. Now, cellphones have become like mini computers with multipurpose cameras, capable of storing substantial amounts of data, recording videos and music, linking to the internet, playing games and a whole host of other features. These phones fall under the category of smartphones owing to their intelligent capabilities. So essential have they become to consumers that the third quarter of the year 2011 saw 115 million units of these phones being sold worldwide.
A new report shows that multifamily buildings—analyst-speak for apartment buildings—could save residents and owners both up to $3.4 billion across America if simple energy efficiency upgrades were made.
