image for Thin film converts heat from electronics into energy

Nearly 70 percent of the energy produced in the United States each year is wasted as heat.

Much of that heat is less than 100 degrees Celsius and emanates from things like computers, cars or large industrial processes.

The thin-film system uses a process called pyroelectric energy conversion, which the engineers’ new study demonstrates is well suited for tapping into waste-heat energy supplies below 100 degrees Celsius, called low-quality waste heat.

Pyroelectric energy conversion, like many systems that turn heat into energy, works best using thermodynamic cycles, kind of like how a car engine works.

“These thin films can help us squeeze more energy than we do today out of every source of energy.”.

“All we’re doing is sourcing heat and applying electric fields to this system, and we can extract energy.”.

The next steps in this line of research will be to better optimize the thin-film materials to specific waste heat streams and temperatures. »

NASA's Got a Plan for a 'Galactic Positioning System' to Save Astronauts Lost in Space

And NASA wants to use them to navigate probes and crewed ships through deep space.

In the vastness of outer space, it's just not possible to figure out a ship's location precisely enough to engine-firing just right.

Your phone's GPS works fast, but Arzoumian said the galactic positioning system would work slower —taking the time needed to traverse long stretches of deep space. »

North and South Korea reportedly set to announce official end to war

North and South Korea reportedly set to announce an official end to war 6 Hours Ago | 00:46.

North and South Korea are in talks to announce a permanent end to the officially declared military conflict between the two countries, daily newspaper Munhwa Ilbo reported Tuesday, citing an unnamed South Korean official.

Pyongyang and Seoul have technically been at war since the 1950-1953 Korean conflict ended with a truce — and not a peace treaty. »

Puma vs Adidas: Return of the battle of the boots

Probably because she knows that what most who come to this north Bavarian town are looking for is a fight.

"Some of the stories you hear are just mind-blowing," says Filip Trulsson, marketing manager of team sports at Puma.

Herzogenaurach has been described as "the town of bent necks," as no local would start a conversation with another without first looking down to check which firm's shoes they were wearing. »
