Italy is known for its plans to develop photovoltaic power as one of their main sources of energy. Having such a wide experience in solar power harvesting, several issues arise regarding the solar panels' maintenance. Every PV plant has a sensor verifying the quantity of light arriving at its location at any given moment during the day.

Too often, regardless of the energy sources being used, the GSM transmission towers' power fails, because of various reasons: theft, heavy rain/snow, disturbances in the grid lines. Helix, a San Diego-based wind company, is working on a wind turbine that is designed to power base stations in hard to reach, remote locations from Africa and the US.

Fraunhofer Develops New, Easy to Make High Efficiency Solar Cells

Ovidiu Sandru — Tue, 29 Sep 2009 16:06:01 +0000

Yet another efficiency record has been established for mass-producible solar cells: 23.4%. The Fraunhofer Institute for Solar Energy Systems (ISE) from Germany succeeded to manufacture a single-crystal silicon solar cell of a thin p-type semiconductor layer residing on an n-type semiconductor substrate. The solar cell's area is 2x2cm.

Mimicking nature has been man's dream since he tried inventing the airplane, and even earlier. Mimicking a leaf for obtaining energy from the Sun has been even more challenging than learning to fly, though, until now, nobody succeeded imitating the evolution or creation or whatever our nature is made of.
