Digital warrior a hero or villain?
Digital format, the chief warrior from the digital world has struck once again. This warrior, who sounded the death knell of the vinyl record from the AV world with weapon CD/DVD, now has its sight focused on Hollywood/Bollywood and is all set to shoot out 35mm film along with the projector from the film world.
Digital format is now feeding its imagery and claiming its supremacy through TV, Internet, digital camcorder pro cameras lap-tops and the conquest goes on unabated. Initially in their earlier adventure with digital camera, filmmakers employed them to plan out their shots, rehearsals and for location hunting. Then came in movies like Hidden and District 9 shot in digital format and their success heralded the era of professional filming with digital cameras. Now even a fairly low budget digital camera is capable of reproducing high quality images.
Talk and Charge!
In the near future every cellphone owner will soon be charging his pone battery by just chatting on his cell and the more he talks the more he will increases battery life — provided the innovative research by a group of Korean scientists produces the right results. These scientists claim to have successfully developed a material which can convert sound waves to electricity. This research could lead to making of small modules that can charge a cell phone during conversation. Presently the voltage produced is too low be utilised for commercial purpose. The present generation phones use more voltage than this technology can produce, researchers worldwide are working on several ideas to boost this voltage.
This research works on the reverse principal of loud speakers which transform electric signals to sound. Till the Koreans prove their point let’s talk less for presently the more we talk the more the battery consumption. So don’t worry, the future is bright.
