Perpetual Printing

Printing has come a long way since the computer landed on the desktop. First, there were daisy-wheel printers, then dot-matrix printers, then inkjet and laser printers. The problem with all of these output devices, of course, is that they require paper -- lots of it -- and expensive consumables, like toner. Why can't someone invent an inkless, tonerless printer that allows the operator to reuse paper?As it turns out, this isn't a new idea. Xerox has been working with so-called electronic paper since the 1970s. Its most promising solution is a type of paper called "Gyricon." A Gyricon sheet is a thin layer of transparent plastic containing millions of small oil-filled cavities. A two-colored bead is free to rotate inside each cavity. When a printer applies a voltage to the surface of the sheet, the beads rotate to present one colored side to the viewer, offering the ability to create text or pictures. The images will remain on the paper until it's fed through the printer once again.A Japanese company, Sanwa Newtec, is offering its version of inkless, tonerless and rewritable printing technology. Its product is called the PrePeat rewritable printer, which, like the Xerox solution, requires plastic paper. But PrePeat uses a different technique to produce an image. Each sheet of paper comes embedded with leuco dyes, which change color with temperature -- colored when cool and clear when hot. The PrePeat printer, then, heats and cools the paper to first erase an image and then create a new image in its place. According to the company, a single sheet of paper can be reused 1,000 times before it needs to be replaced. A single PrePeat printer costs almost $6,000, while a pack of 1,000 sheets of paper costs more than $3,300. 

Now You Can Generate Electricity While You Walk On This Floor

In the sustainable energy market, Energy Floors, a Netherlands-based firm is trying hard to make its place. They sell products like Sustainable Energy Floor and Sustainable Dance Floor, that convert footsteps into electricity. As soon as anyone steps onto the floor, the tile flexes round about 10mm  and that movement is converted into electricity-15 Watts on average, and up to 25 Watts peak. If the tiles are connected together, 40 to be precise, the network can produce up to 1 kW and this is possible due to the modular nature of these tiles.

Although we do not know how these magnificent tiles are made but for what we know is that it’s not piezoelectric. For what we can see, it looks like a rack-and-pinion that drives a small permanent magnet generator.The flow of electricity is directed by a controller module. Charging low voltage devices, charging batteries, or lighting pathways with LED's is all that can be done from the 12Voutput.

When you step on the blocks, they light up and this intrigues people to step on them again. Thus it would be an attractive marketing technique too. Solar, wind, and hydroelectric are the big players, but small energy-harvesting products have their place as well. A journey of a thousand miles begins with a single step. 'Energy Floors could make that step more productive.'

Scientists Discover A New Layer In Human Eye

What is so fascinating about science? It’s always progressing towards something new and what is considered top notch today will be outdated in a few years. However, a discovery in human anatomy is something we weren’t expecting to take place but it did! As it happens, the latest discovery about human anatomy is only 15 microns thick, but contrary to its thickness, this discovery is bound to have a huge impact on medical science. For starters, this discovery will result in making eye surgery much simpler and safer as compared to the present risks associated with eye surgery. The discoverer of this new found layer is Professor Harminder Dua  at the University of Nottingham.

He found a new layer present in the human cornea and has named it after him; Dua’s layer. This particular layer lies at the back of the cornea, the same cornea which was believed to have only five layers previously. The methodology in finding out this layer included Dua injecting air into the cornea and making use of an electron microscope to completely analyze each layer by scanning it. The eyes used for this research were, of course, the ones that had been donated for such research purposes. How many of you have heard about corneal hydrops? It is this disorder which allows for the building up of fluid in the cornea. The research team believes that a tear in Dua’s layer is the cause for this disorder.

The team also believes that the finding of this new layer will drastically improve the surgery outcomes related to corneal grafts and transplants. Professor Dua had the following to say regarding the new discovery; ‘This is a major discovery that will mean that ophthalmology textbooks will literally need to be re-written. From a clinical perspective, there are many diseases that affect the back of the cornea which clinicians across the world are already beginning to relate to the presence, absence or tear in this layer.’ 

USB

Short for Universal Serial Bus, an external bus standard that supports data transfer rates of 12 Mbps. A single USB port can be used to connect up to 127 peripheral devices, such as mice, modems, and keyboards. USB also supports Plug-and-Play installation and hot plugging.
Starting in 1996, a few computer manufacturers started including USB support in their new machines. It wasn't until the release of the best-selling iMac in 1998 that USB became widespread. It is expected to completely replace serial and parallel ports.
