IBM Research has conceived the plan to old, depreciated laptop for applications such as lighting. The technology used would be especially useful, and inexpensive in areas with limited or unreliable access to electricity.
The research of IBM describes the UrJar, a charging system in which a number of old laptop is reused to save energy. The researchers suggest that these lithium-ion batteries, although not good enough for laptops of electricity to be provided, but often still good enough for less critical applications; approximately 70 percent of the depreciated batteries would can be re-used for the burning of a led light bulb, run a fan or to a usb charger.
The UrJars that IBM built had an average of about a capacity of 50Wh. Were amortized lithium-ion cells Thinkpad laptops from Lenovo that are charged when electricity is available. The UrJars were vevolgens to an average of four hours power supply when no electricity was available.
According to the researchers, the technology used is useful in areas where access to electricity is limited or where power supply is unstable. IBM did its research in India, a country where in many areas the electricity supply is left. By old laptop a second life, for instance, would the owners of small shops in the evening and night longer remain open because there is light. In addition, point out the researchers on the fact that the re-use of depreciated lithium-ion batteries for potential use of milieuonvriendelijker lead-acid batteries can help reduce.
