Reintroducing the Sun : Parans SP2


This isn’t the first time that we here at architecture.MNP have brought you natural lighting solutions – but this product looks to be iller than those that we’ve previously featured. Parans SP2 is a natural lighting solution that utilizes active tracking Fresnel lenses to focus sunlight through a fiber optic delivery system.

Don’t know what a Fresnel lens is? [I didn’t…]:

A Fresnel lens is a type of lens invented by French physicist Augustin-Jean Fresnel. Originally developed for lighthouses, the design enables the construction of lenses of large aperture and short focal length without the weight and volume of material which would be required in conventional lens design. Compared to earlier lenses, the Fresnel lens is much thinner, thus passing more light and allowing lighthouses to be visible over much longer distances [via Wikipedia].


So basically the system uses these lenses to focus sunlight and distribute it throughout the spaces in which the system is installed, through the use of fiber optic cables running through the building. Based on the other product like this one that we had on MNP, and other solar lighting systems I’ve seen/read about, my guess is that this would most likely be a hybrid system, regardless of what the company advertises. But regardless – not only has it been proven that natural light is better for you, but adding any amount of it to your building’s lighting system is going to reduce your energy consumption, which is always siiick.

  1. […] Our ninjas over at arch.mnp recently brought us this post on Parans SP2, a technology that channels natural sunlight through fiber optic cables into the indoors. Interestingly, this reminded me of a technology that utilizes the same light-sequestering concept to grow algae from CO2. Algae, as many of you may know, has been deemed by some to be the future of the biofuels industry. Not only will algae eat up CO2 (and NOx) from power plants, ethanol plants or any other CO2 producing industry, but it is an ideal [non-edible] source of oil for making biodiesel. The stuff can also be fermented to make ethanol, gasified to make methane/syngas or dried to make solid biomass. […]
