The new figures do not inlcude the free ebooks, which would push the ratio of ebooks to print ones even further in the ebooks favor. The numbers do include, however, print books that are not available in a Kindle edition. Read more…
How cool would it be if your cell phone could gain all the power it needed to fuel your conversations by the actual sound of those conversations? Scientists at Sungkyunkwan University in Seoul, South Korea think they’ve developed the technology that could soon have that very application.
The technology produces energy from the vibrations caused by sounds. The prototype consists of tiny zinc oxide wires sandwiched between two electrodes. A sound pad on top vibrates when hit by sound waves which causes the zinc oxide strands to compress and release. That generates an electrical current that charges the battery.
Currently, the prototype has only been able to convert sound at high decibel levels like loud traffic to generate about 50 millivolts of electricity, but the scientists are hoping that changing the material the wires are made of will allow more energy to be produced from lower sound levels.
The company said that they earned $3.07 billion, or $3.33 a share, in its fiscal second quarter, which was $1.33 a share a year before. Most recent sales went up to $13.5 billion, which was $8.163 billion last year.
Canadian company Daymak has is releasing their wireless electric bicycle called the Shadow Ebike at this year’s China Import and Export Fair, also known as the 109th Canton Fair, hosted in Guanzhou near the southeast coast of China.
The Shadow Ebike features wireless magnetic regenerative brakes, wireless throttle, and wireless pedal assist, coming equipped with either a 250 watt or 350 watt motor. With a 36 volt 10AH lithium battery, and weighing 59 pounds, the electric bike has a top speed of around 20 miles per hour, and a range of about 15 miles without pedal assistance.

The mining industry
The mining industry is one of the most toxic in the world. It has a massive impact on the local environment as a polluter of air and water supplies and often creates deforestation. Mining naturally plays a direct hit to the lungs and wellbeing of the miners themselves and in many countries across the world has created long-lasting civil conflict and even wars. Whether its sustainable metals, blood diamonds or native American turquoise, how ethical is our jewelry?
We might think we are supporting local artisans around the world, when we buy their crystal and macramé dreamcatcher necklaces, but what is the impact on the local environment?
A challenge for jewelry designers who want to move things in a positive direction is the lack of sustainable raw materials and very few industry standards. There is one fair trade gold mine in the world, but no ethical silver mines. Read more…
Bicycle inner tubes that contain a small-puncture-sealing slimy liquid may not be a new development in and of themselves, but Michelin has released a product that takes the concept a step further. The company’s Protek Max tube not only contains a sealant, but is designed to compress when punctured to assist the self-sealing process.
The two things you’ll notice about the Protek is that it has a square cross-section, and funny little bumps on its surface. The square shape helps align it within the tire casing and against the rim well, which Michelin says eases mounting and eliminates the twisting problems that can occur with traditional sausage-shaped tubes.
When the tube is fully inflated within the tire, its textured surface causes the rubber to compress instead of expand when under pressure. This means that the internal air pressure actually closes holes off, giving the sealant a better chance at taking care of them for good.
The tubes also are claimed to hold air longer – when tested against Michelin’s self-sealing AIRSTOP tube, the Protek was said to maintain proper pressure for twice the amount of time.
Commuters and mountain bikers, but not road racers, can get a Protek Max to fit their tire. It is available in sizes of 700 x 35-47c (200 grams) and 26 x 1.4-2.125 inches (260 grams), with Presta or Shrader valves, for a suggested retail price of US$8.99.
