Micro-machining could be used to create almost flat, Fresnel lenses, that boost the electrical efficiency of solar panels, according to new research. Micro-machining could be used to create almost ...

Fresnel lenses are used to concentrate solar radiation to a line or point. A linear Fresnel lens (0.91 by 1.52 m, 0.74-m focal length, 0.01- by 1.52-m line focus) was investigated as a method for weed ...

Using the technology available today, half of the global energy demand in 2050 can be met by renewable energy sources. This has been proven by current scenarios in which a major role has also been ...

Although one of the lower scoring teams at this year’s Solar Decathlon Europe competition in Madrid, the Sumbiosi house has extraordinary potential and shouldn’t be discounted just yet. Not only does ...

Linear Fresnel reflector (LFR) technology has emerged as a competitive and cost‐effective alternative within the concentrated solar power (CSP) field. By utilising an array of flat or slightly curved ...

The hydrofoils, which are similar to airfoils used by airplanes, lift the boat’s hull out of the water to decrease drag and allow for greater speeds. The combination of the Fresnel lens and ...

The science pros at The King of Random demonstrate making a solar cooker using a Fresnel lens. Audit Finds $1B in Improper Medicaid Payments 'My hopes are dashed': Illegal Indian migrants deported by ...
