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
