The technology giant IBM has become a world-renowned player in the IT industry. It has involved many areas such as servers, semiconductors, and solutions, and has established many important standards and specifications. Many people may only think of IBM as an IT company, but it is not. IBM is also involved in some other areas, such as research on new energy sources. IBM recently announced a new achievement in solar power generation, which can increase 2000 times the efficiency of traditional solar power generation, while the cost is significantly reduced.
IBM imagines using an array of hundreds of photovoltaic chips to form an umbrella array that concentrates solar energy by changing the orientation of the photovoltaic chips. In order to prevent the chip from being burned due to excessive temperature, the interior is filled with dense water pipes to cool down. Cooled water as a by-product can provide residents with cheap hot water, which can serve two purposes.
Each photovoltaic chip can provide 200 to 250 watts of electricity during the day. A complete array containing hundreds of photovoltaic chips provides stable 25 kilowatts of electrical energy. This new type of power generation equipment costs about US$250 per square meter, only one-third of traditional solar cells, and the cost of electricity is only US$0.1 per kilowatt-hour (per degree), which is comparable to the cost of thermal power generation. I believe this Solar power generation technology will soon be practical.
