Not to sound like a tree-hugging hippie…but, in my opinion, which is pretty much regarded as fact in most academic circles, there is no reason the world should be so heavily reliant on one type of power source to run our motor vehicles. With the amount of scientific man power out there in this increasingly global community there is no excuse for being so technologically narrow. GMs E-Flex Propulsion System, found in the Concept Chevy Volt, could be a step forward in breaking the world’s reliance on gasoline.

Any serious music lover would definitely have built up a sizable collection of audio CDs over the past two decades, and while the CDs sound as good as they were from the first day of purchase, the same might not apply to the CD jewel cases and album art. Chances are these cases will be scratched or even cracked, while the album art and inserts would definitely have received some dog ears through a regular thumbing process from yourself and friends who borrowed part of your collection. How about having a single CD jewel case that stores all your album art without the dangers of getting damaged? David Friedman thought of this concept by working on a digital CD jewel case.
Most of us have grown up watching more than enough war and science fiction movies to know that night vision images are often seen as an eclectic mix of green and black. Tenebraex has upped the ante by developing a pair of goggles that help both soldiers and physicians to see an entire spectrum of colors at night - a vast improvement over what is currently available in the market. These goggles will be made available to the Army for approximately $6,000 a pop, making it out of reach for the average Joe. 
At first glance, the square on the right actually looks like a transparent film of some sort, but you will be surprised to know that it is actually a battery. I know I was surprised myself, but what we see is actually a polymer based rechargeable battery developed by Japanese scientists from the Waseda University. This unique battery is made from a 200 nanometre thick (or should the right word be thin?) redox-active organic polymer film that come with nitroxide radical groups attached to it. These nitroxide radical groups act as charge carriers, offering a high charge/discharge capacity thanks to the high radical density. Other than this advantage over regular batteries, it was interesting to note that the power rate performance is nothing short of jaw dropping - it takes a mere minute to charge the battery fully and boasts a superior cycle life of over a thousand cycles.
