MIT researchers have uncovered the “photomolecular effect,” a process “that demonstrates for the first time that water can evaporate with no source of heat using light alone,” reports Anthony Cuthbertson for The Independent. The “discovery could impact everything from climate change calculations to weather forecasts, while also opening up new practical applications for things like energy and clean water production,” writes Cuthbertson.
Researchers at MIT have discovered that “light in the visible spectrum is enough to knock water molecules loose at the surface where it meets air and send them floating away,” reports Michael Franco for New Atlas. “While the distinction between light-caused evaporation and heat-caused evaporation might not seem like a big one, the researchers say it could not only have a big impact on the way future evaporative projects are executed, but that it could also explain a long-standing discrepancy involving clouds,” writes Franco.
Interesting Engineering reporter Rizwan Choudhury spotlights a new study by MIT researchers that finds light can cause evaporation of water from a surface without the need for heat. The photomolecular effect “presents exciting practical possibilities,” writes Choudhury. “Solar desalination systems and industrial drying processes are prime candidates for harnessing this effect. Since drying consumes significant industrial energy, optimizing this process using light holds immense promise.”
Research engineer Paul Woskov speaks with Bloomberg Radio host Tom Moroney and Joe Shortsleeve about his work with Quaise Energy in developing a laser to drill holes into the earth. “There is a lot of heat contained within our planet. The amount of heat that is present, if tapped, could supply all of our energy needs for several million years,” says Woskov.
A new study by MIT researchers that sheds light on heat transfer in boiling water could allow nuclear power plants to run more efficiently, reports Jim Efstathiou Jr. for Bloomberg News. “Learning more about how heat is transferred could help safely boost the output from nuclear power plants by as much as 20 percent,” Efstathiou explains.
Prof. Carlo Ratti has created a metal canopy that can control light and shade, and can be used to create microclimates in outdoor areas, reports Sophie Morlin-Yron for CNN. Morlin-Yron writes that Ratti explained that “the aim is to curb the heat that makes public areas in places like Dubai ‘unlivable’ during the hottest times.”
A new technique developed by MIT researchers for capturing waste heat that can be used to produce electricity has been named one of 10 World Changing ideas by Scientific American, reports Ryan Bradley. “This is something attractive,” says Dr. Yuan Yang, a postdoctoral associate at MIT, “because low-grade heat is everywhere.”
Liz Stinson reports for Wired on a project by the Senseable City Lab that aims to reduce wasted energy by using localized beams of heat. The system uses a WiFi-enabled tracking system and can sense when a person is present.
Kerry Flynn of Forbes reports on a new system developed by the MIT Senseable City Lab that reduces wasted energy by creating local, personal climates throughout buildings. The system targets and tracks people in a building and synchronizes climate control by sending data to heat-radiating bulbs.
Writing for Forbes, Neil Kane writes about new technology developed by MIT researchers that allows for solar energy to be captured when the sun is shining and stored for later use.
Atlantic reporter Todd Woody writes about how MIT researchers have developed a way to store solar energy in molecules. The energy inside the molecules can be stored forever and endlessly re-used so that solar power can be accessed even when the sun is not shining, Woody explains.
Boston.com reporter Matt Rocheleau reports on how Professor Jeffrey Grossman and postdoctoral associate Timothy Kucharski have developed a new material that can produce solar power for times when the sun is not shining.
