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 ...

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 ...

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 ...

A research team in Taiwan claims to have discovered the cause of inherent light leakage in high-concentration photovoltaic (HCPV) systems that use a Fresnel lens as a focusing lens. The scientists ...

Using a Fresnel lens taken from an old rear-projection TV, Grant Thompson channelled the heat of the sun into a 1000 degree Celsius ray. Michelle Starr is CNET's science editor, and she hopes to get ...

Fresnel lenses are all around us, but this vase puts the commonplace technology to work in an entirely new way. Borrowed From Old Lighthouses, A Method For Super-Powerful Solar Power With the help of ...

Following official approval of a series of major concentrated photovoltaics (CPV) projects by the California Public Utilities Commission (CPUC), Soitec’s solar energy division is setting up a ...

Micro-machining technology could be used to produce flat lenses which would boost the productivity of solar panels. The Fresnel lens is essentially a two dimensional equivalent of the regular optical ...
