Solar panel used to power an electric fence to coral sheep.

The photographs were taken in the Saas Fee region of Switzerland, close to the border with Italy.

Solar Power in Taiwan



This is the guard at Taiwan Tech, whose daughter studied at Cambridge University


Professor Chin Huai Young at the National Taiwan University of Science and Technology (Taiwan Tech) has invented a glass which is coated with amorphous silicon with an underlying reflective coating


This shows the temperature inside a "house" with ordinary glass


Here is the corresponding temperature in the house with the new glass




The silicon photovoltaic generates some 100 Watts per square metre and this also helps to reduce the ingress of heat into the house












More comparisons




Professor Young's discovery is now going to be applied to automobile roofs, where a car left unattended in the heat can be kept cool inside in summer by fans driven by the photocells, and similarly heated by the electricity in winter
