American Institute of Physics researchers have constructed a photovoltaic cell that works both day and night by making use of the heat leaking from Earth back into space. At night, solar cells radiate and lose heat to the sky, reaching temperatures a few degrees below the ambient air. The device under development uses a thermoelectric […]

Massachusetts Institute of Technology engineers have developed a heat engine with no moving parts that is more efficient than a steam turbine. The researchers say the design could someday enable a fully decarbonized power grid. Their new demonstrations show that it converts heat to electricity with over 40 percent efficiency – a performance better than […]

Japan’s National Institute for Materials Science scientists have developed a new approach to the design of thermoelectric materials. They have constructed a database of electronic structure parameters correlated with materials’ thermoelectric conversion properties and by a comprehensive analysis of the database. This approach can be used to develop higher performance thermoelectric materials. The team’s research […]

New Inexpensive Passive Solar Powered Water Desalination
March 17, 2022 | Leave a Comment
Massachusetts Institute of Technology researchers have developed a desalination system that is more efficient and less expensive than previous methods. In addition to providing fresh water, the process could be used to treat contaminated wastewater or generate steam for sterilizing medical instruments, all without requiring a power source other than sunlight. An estimated two-thirds of […]
