Sewage That Is Full Of Green Energy

GREEN energy – power produced and harnessed during the treatment process in some sewage works in the United Kingdom – is helping to run operations within them.
Southern Water’s project is proving such a success that the utility company has just announced that it is enlarging the programme to start powering more plants.

The Potential of Outdoor Lighting for Stimulating the Human Circadian System

Every species on earth exhibits a wide range of biological cycles that repeat approximately every 24 hours. These are known as circadian rhythms (circa – approximately; dies – day) and are exhibited at every level of biological systems, from timing of DNA repair in individual cells to behavioral changes, like the sleep-wake cycle.

The Bio-Retina Implant Could Give Sight to the Blind, With Laser Power

A new bionic eye implant could allow blind people to recognize faces, watch TV and even read. Nano Retina’s Bio-Retina is one of two recent attempts to help patients with age-related macular degeneration, which affects 1.5 million people in the U.S. Although a similar implant, Second Sight’s Argus II, has been on the market in Europe since last year, it requires a four-hour operation under full anesthesia because it includes an antenna to receive power and images from an external apparatus. The Bio-Retina implant is smaller because it doesn’t have an antenna. Instead, the implant captures images directly in the eye, and a laser powers the implant remotely. Because of Bio-Retina’s compact size, an ophthalmologist can insert it through a small incision in the eye in 30 minutes—potentially more appropriate for seniors. The Bio-Retina will generate a 576-pixel grayscale image. And clinical trials could begin as soon as next year.

Oryon Technologies’ Electroluminescent Lighting Technology: Not Just a Cool Novelty

When investors first take a look at Oryon Technologies and its electroluminescent lighting technology known as ELastoLite, they are probably thinking to themselves: “Well, that’s cool BUT there’s no market for that!” However, that thought could not be further from the truth when you take a closer look at the technology itself. So just what is Oryon Technologies’ ELastoLite and what can it be used for that’s actually useful?

Lighting up your Innards for Incision-less Surgery

If only doctors could operate without ever having to cut through your tissues or even diagnosing cancer, simply by seeing tumors inside with a tool as simple as an ultrasound.
The new diagnostics developed by California Institute of Technology (Caltech) engineers enables researchers to focus light efficiently inside biological tissue. While the previous limit for how deep light could be focused was only about one mm, the Caltech team is now able to reach 2.5 mm.

By Twisting Light Signals into a Vortex, Researchers Create Fastest Wireless Connection Ever

By twisting radio waves into a threaded vortex, an international team of researchers has beamed data through the air at 2.5 terabits per second, creating what has to be the fastest wireless network ever created. Moreover, the technique used to create this effect has no real theoretical ceiling, ExtremeTech reports. That means–in theory–that an infinite number of these vortex beams could be threaded together to add infinite capacity to conventional transmission protocols.

Outdoor ‘Smart’ Lighting System to Save Energy and Enhance Safety

The University of California, Davis, has unveiled one of the most advanced outdoor lighting systems in the country, a roughly $1 million network of “smart” lights that talk to each other and adapt to their environment.

The $950,000 project is part of the university’s Smart Lighting Initiative, established in 2010 to reduce campus electrical use by 30 million kilowatt hours — or to 60 percent of 2007 levels — by 2015. The new outdoor lights promise to save the university $100,000 a year on electricity, shrink its carbon footprint and make it a safer place after dark.
