Electricity from CPU waste heat
If the researchers at the Massachusetts Institute of Technology continue to research successfully, the battery life of laptops could be significantly extended. With the help of a thermionic converter, electricity can be generated from heat.
This heat converter basically consists of two parallel circuit boards, if one is heated, electrons begin to flow between the circuit boards, i.e. a current flows. Up to now, this technology was only possible at high temperatures of around 1000 ° Celsius, the researchers have now developed a converter that works from 100 ° Celsius. This is able to convert around 17 percent of the thermal energy into electricity, but the researchers want to achieve a yield of at least 20 percent in the near future. In addition to PC technology, the thermal converters could also be used in car engines to generate electricity for vehicle electronics.
