SAN DIEGO (KGTV) - Imagine having the power to change your body’s temperature at any time, regardless of how hot or cold it actually is. UC San Diego engineers are on they’re way to doing just that, with a wearable patch.Like a thermostat, it can be changed to a specific temperature, warming or cooling the body, using far less energy than an air conditioning system. “Cooling is a really important issue faced by society today. If you look at news reports there are extreme weather conditions, for example in India, peak temperature could be over 50 degrees Celsius in July," said Renkun Chen, a Professor of Mechanical and Aerospace Engineering at UC San Diego.The patch is made up of thermoelectric alloys - materials that use electricity to create a temperature difference and vice versa - sandwiched between stretchy elastomer sheets. The device physically cools or heats the skin to a temperature that the wearer chooses. The patch is powered by a flexible battery pack. It is made of an array of coin cells all connected by spring-shaped copper wires and embedded in a stretchable material. The system also includes a stretchable circuit board.By regulating the temperature around an individual person, rather than a large room, the smart fabric could potentially cut the energy use of buildings and homes by at least 15 percent.The technology could also be used for people who work in extreme environments, like firefighters or miners. Eventually, Chen and his team want to integrate the technology into clothing. They hope to sell it commercially in the next few years, along with developing a mobile app to control the temperature. The research was funded with a .6 million grant from the U.S. Department of Energy. 1736

SAN DIEGO (KGTV) — Last year, California voters overwhelmingly approved a measure to make Daylight Saving Time permanent. So why are we still springing forward and falling back an hour?Specifically, Proposition 7 was passed to allow the state legislature to vote to adopt Daylight Saving Time year-round with congressional approval. There lies the answer: congressional approval.Though California has yet to hold a vote, the change to year-round Daylight Saving Time would require Congress' backing. Florida voted for the shift in 2018, but are still waiting on Congress.RELATED: Trump: Making daylight saving time permanent is 'OK with me'California Assembly Bill 7, introduced in December 2018 by Assemblyman Kansen Chu, is currently being held until the second half of the 2020 legislative session, according to the Sacramento Bee. The bill, as written, would set California's standard time to year-round Daylight Saving Time — after the government authorizes the state to do so.If that approval were to come, California would apply year-round Daylight Saving Time beginning the second Sunday of March at 2 a.m.Chu said Friday he plans to introduce a resolution in Congress to authorize the change come in January.RELATED: Daylight Saving Time is here: Remember to set your clocks forward this weekend“I am committed to ending the harmful practice of switching our clocks twice a year and delivering on the voter’s decision at the ballot box in support of Proposition 7,” said Chu. “I share voters’ frustration that we will be shifting back to standard time on Sunday. Unfortunately, California and other states cannot move forward with permanent daylight saving time without authorization from the federal government."In January, I will introduce an Assembly Joint Resolution urging Congress to authorize states to practice permanent daylight saving time and continue my work to pass Assembly Bill 7 so California is ready for when Congress decides to take action."California is one of 14 states this year to introduce legislation for permanent Daylight Saving Time. There are also four bills waiting in Congress that could allow California and other states to make the time shift: H.R. 1556, S. 670, H.R. 1601, and H.R. 2389. Congress has until December 2020 to act on those bills.For now, Daylight Saving Time will end at 2 a.m. on Sunday, Nov. 3. 2361

SAN DIEGO (KGTV) - It’s a great time to buy a used car. “These deals are once in a lifetime,” said Ivan Drury, a used car expert with Edmunds. Amid the uncertainty caused by the coronavirus pandemic, used car prices have been decreasing. According to Bloomberg News, the average price of a used car fell 11.4% from March to April. Drury predicts those prices could continue to fall, as desperate rental car companies start to offload unused inventory. Hertz, which filed for bankruptcy on Friday, has a fleet of about 500,000 vehicles. It’s unclear what their plan is for them, but Drury suspects they will only keep enough to maintain a basic level of service. “That influx of used vehicles will have a dramatic impact on price,” he said. Adding to the supply of used cars, Drury predicts that some drivers who have leased cars will hold on to them for a few more months rather than trade them in. But in several months to a year, he expects that could lead to another flood of used vehicles. “You kind of have a perfect storm for used car values to drop even further,” said Drury. 1090

SAN DIEGO (KGTV) — In a typical year, California teachers spend an average of 4 of their own money on classroom supplies, but with districts preparing for distance learning this fall, educators are facing a different set of expenses.In the Vista Unified School District, 5th-grade teacher Keri Avila said she had to create a home office, starting with upgrading her internet.“I think in the beginning it was an oversight. The schools did a really good job making sure students had connectivity and I think you expect teachers would have the connectivity they need. But a lot of us didn’t,” said Avila, who is also the vice president of the Vista Teachers Association.Many teachers in the South Bay Union School District had to upgrade their internet bandwidth, especially with other family members working from home simultaneously, said Vanessa Barrera, a 3rd-grade teacher, and president of the Southwest Teachers Association.In a survey at the beginning of the pandemic, 1% of the teachers in her district said they had no internet at all. Twenty-five percent said they lacked a home office workspace, she said.Although districts provided laptops for educators, some teachers purchased office furniture, web cameras, specialty applications, and other equipment to facilitate lessons.“In our district, we were just provided with our laptop," Barrera said. "We were not allowed to bring home the printers, document cameras, Elmos.”An Elmo is similar to an overhead transparency projector that connects to a computer. Barrera said some teachers in her district had to rig together solutions of their own, using cell phones and flexible stands purchased online.Districts have pledged to roll out mobile hotspots to teachers with connectivity issues, but the cost of upgraded home internet continues to be the subject of negotiations between districts and unions, Avila and Barrera said.Classroom costs could rise once students return to campuses because of CDC guidance that kids should not share supplies.“Previously you might have bought a pencil box for a table to share, well that’s not going to be acceptable now,” said Barrera. “Whatever the cost will be for the coming year will depend on what this school year will look like, but as teachers we just forfeit the money to make sure students have what they need.” 2328
