Could ‘smart’ stoplights cut fuel waste and carbon emissions? Roadshow reader runs numbers

Published Tue, 04 Mar 2025 11:30:55 GMT

Q: The time wasted when stopped at traffic lights should not be the concern. What should be a concern is the fuel wasted. This state burns roughly 14 billion gallons of gas per year. For each gallon burned, 20 pounds of carbon go into the atmosphere. If we could reduce the amount of fuel burned by just a little more than 7 percent, we could save roughly 1 billion gallons of gasoline and keep 20 billion pounds of carbon out of the atmosphere. At 5 bucks a gallon that is also $5 billion in savings to motorists each year. I say this could easily be done by adjusting traffic light cycles. We don’t have to wait for smart lights.I know one intersection that constantly seems to have changing cycles, Los Padres and El Camino in Santa Clara. One recent morning at 7 a.m., the complete cycle took about a minute and a half. No cars went through the intersection for roughly one minute of this cycle, Southbound Los Padres was green for 30 seconds so one car could go through. Multiply this by the ...

Maui was criticized for not using sirens during wildfires. Does the Bay Area have a smarter approach?

Published Tue, 04 Mar 2025 11:30:55 GMT

As Maui recovers from the deadliest U.S. wildfire in the last century, many have criticized Hawaiian officials for not sounding the island’s emergency sirens — prompted by fears of unintentionally sending residents towards the flames.That disaster led San Francisco leaders this week to reinvigorate long-overdue repairs to the city’s World War II-era siren system — an early warning service not every county across the Bay Area is equipped to offer.Instead, a patchwork of old-school and cutting-edge alert systems have been implemented across Alameda, Contra Costa, San Mateo and Santa Clara counties — culminating in a hodgepodge of sirens, loudspeakers, social media, texts and even doorbells to warn residents of impending disaster.By 2008, emergency coordinators in San Mateo County had installed eight sirens along its low-lying coastline that are sounded exclusively for tsunami warnings, according to coordinators Rick Reed and Jeff Norris. Rather than set u...

MILAN (AP) — American standout Christian Pulisic came to AC Milan to revive his flagging club career.Its very early days but, having linked up with former Chelsea teammate Olivier Giroud, Pulisic has made an encouraging start.Pulisic enjoyed a dream debut for his new club on Monday when he scored a stunning goal and had a hand in the opener as Milan opened its season at Bologna with a 2-0 win.That was away. This Saturday he steps out on the San Siro turf for the first time in the Rossoneri colors when Milan hosts Torino.“I can’t imagine what it’s going to be like at home,” Pulisic said. “I was able to experience it last season when we played against Milan and it’s going to be nice to have the fans on my side this time.”Pulisic was an unused substitute last October when Chelsea played at San Siro in the Champions League group stage and beat Milan 2-0. That was a common position for Pulisic in his fourth season at Chelsea as he struggled for playing time.Pulisic scored 26 goals in 145...

Turkey’s central bank unleashes a big interest rate hike in another sign of an economic shift

Published Tue, 04 Mar 2025 11:30:55 GMT

ANKARA, Turkey (AP) — Turkey’s central bank raised its key interest rate by an aggressive 7.5 percentage points on Thursday, a larger-than-expected boost that offers a new sign of a return to more traditional economic policies under President Recep Tayyip Erdogan.The bank hiked its policy rate to 25% as it continues to backtrack from a rate-cutting course set by Erdogan, which has been blamed for inflaming a cost-of-living crisis. Many households have been left struggling to afford rent and basic goods as inflation has surged.The increase “will go a long way towards reassuring investors that the shift back to policy orthodoxy is on track,” London-based Capital Economics research firm wrote in an analyst note.It called the move a surprise as most analysts expected a much smaller bump in borrowing costs.“As far as Turkey’s macroeconomic outlook is concerned this could be a game-changer,” the firm said.Erdogan has long argued that lowering interest rates helps fight inflation, a theory...

Breakthrough cryofreeze technique means brighter future for coral reefs. Could it also preserve humans?

Published Tue, 04 Mar 2025 11:30:55 GMT

Marine biology researchers have achieved a breakthrough in the fight to save the world’s coral reefs from climate change annihilation. This comes as water temperatures recorded off the coast of Florida reached triple digits this summer, and scientists continue to sound the alarm about the effects of climate change on our ocean ecosystems.This breakthrough, which involves cryogenics, is one researchers said might also be the next step in human evolution — by preserving or extending human life.“This has been going on for many, many years,” said Mary Hagedorn, senior research scientist with The Smithsonian National Zoo and Conservation Biology Institute.Hagedorn, who also works with the Hawaii Institute of Marine Biology in Oahu, co-authored a paper that was published Wednesday, outlining the first successful technique cryopreserving and reviving entire coral fragments.She told WTOP corals have been in decline for a while, and “have been facing many threats related to...

GENEVA (AP) — FIFA opened a disciplinary case Thursday against the Spanish soccer official who kissed a player on the lips while celebrating the team’s victory in the Women’s World Cup final.The governing body’s disciplinary committee will weigh if Spanish soccer federation president Luis Rubiales violated its code relating to “the basic rules of decent conduct” and “behaving in a way that brings the sport of football and/or FIFA into disrepute.”Rubiales kissed player Jenni Hermoso on the lips during the trophy and medal ceremony on Sunday after Spain’s 1-0 victory over England in Sydney, Australia.Minutes earlier, Rubiales grabbed his crotch as a victory gesture in the exclusive section of seats with Queen Letizia of Spain and 16-year-old Princess Sofía standing nearby.Hermoso has said she did not like the kiss and the national players’ union representing her — which the 46-year-old Rubiales once led — called Wednesday for his conduct to not go unpunished.FIFA res...
