Harnessing natural light, indoors

Gabriel — Tue, 08 May 2012 19:37:34 +0000

Using the most recent generation windows, architects and lighting designers can to control daylight, directing it where they want within a room. An EPFL laboratory has developed a simulation tool to make access to this technology more widely available. How can the diffusion of natural light be sent into the farthest corners of a room […]

Fiber optic cables to light Delancey Underground proposed park in NY

Adrian — Mon, 09 Apr 2012 17:19:52 +0000

An interesting project in New York East Side was proposed by James Ramsey and Dan Barasch to use sunlight to illuminate the Delancey Underground (Low Line). As was described in an article on TreeHugger, the project will use a system of fiber optic cables to collect sunlight above the ground and spread it down into […]

A novel way to capture sun’s thermal energy

Gabriel — Fri, 02 Dec 2011 17:58:59 +0000

Most technologies for harnessing the sun’s energy capture the light itself, which is turned into electricity using photovoltaic materials. Others use the sun’s thermal energy, usually concentrating the sunlight with mirrors to generate enough heat to boil water and turn a generating turbine. A third, less common approach is to use the sun’s heat — […]

How to bring sunlight into your home

Gabriel — Tue, 04 Oct 2011 19:20:15 +0000

The science of light and liquids has been intimately entwined since Léon Foucault discovered the speed of light in 1862, when he observed that light travels more slowly in water than in air. This physical harmony between the two materials is now being harnessed to collect and drive light to where it can be the […]

Harvesting sunlinght as chemical fuel that can be stored

Gabriel — Sat, 01 Oct 2011 06:46:51 +0000

Solar cell bonded to recently developed catalyst can harness the sun, splitting water into hydrogen and oxygen. Researchers led by MIT professor Daniel Nocera have produced something they’re calling an “artificial leaf”: Like living leaves, the device can turn the energy of sunlight directly into a chemical fuel that can be stored and used later as […]

Nanocone – based solar cell with 80 percent conversion efficiency

Gabriel — Mon, 02 May 2011 19:07:43 +0000

With the creation of a 3-D nanocone-based solar cell platform, a team led by Oak Ridge National Laboratory’s Jun Xu has boosted the light-to-power conversion efficiency of photovoltaics by nearly 80 percent. The technology substantially overcomes the problem of poor transport of charges generated by solar photons. These charges – negative electrons and positive holes […]

Sunlight to hydrogen system works, researchers confirms

Gabriel — Thu, 03 Feb 2011 20:41:30 +0000

Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed a biohybrid photo-conversion system — based on the interaction of photosynthetic plant proteins with synthetic polymers – that can convert visible light into hydrogen fuel. Photosynthesis, the natural process carried out by plants, algae and some bacterial species, converts sunlight energy into chemical […]
