Wellness Design Solutions Address Retracted CDC Aerosolized Covid-19 Transmission Risk Guidance

Smart home technology can reduce the risk of indoor Covid transmission. Delos - Anthony Barcelo (Photographer) The Centers for Disease Control posted updated Covid-19 transmission information on its website last Friday and removed it on Monday, claiming the posting was done in error with draft copy. The crucial information in the update concerned aerosols and small airborne particles carrying enough of the virus to infect people beyond the six-foot radius often cited as a safety margin, especially within poorly-ventilated spaces. This mirrored guidance that the World Health Organization addressed last July. Aerosolized transmission can have a significant reopening impact for schools, gyms and other public and commercial facilities – but it also impacts living spaces, includin...

The 2021 Ferrari 250 GT SWB Competizione Revival is a Million Dollar Bargain

Let’s say you have $1-2 million to splurge on a really nice car. Your investment in disinfecting wipes and video chat software has paid off big. Now you want to treat yourself to a killer set of wheels that can provoke envy and lust on all who see it. But, you don’t want a modern supercar because they are too flashy and borderline vulgar in some aspects, hard to see out of, and low-profile tires hurt your back. You want a classic GT car, but don’t have the budget to bid against billionaires.What you want is a 2021 Ferrari 250 GT SWB Competizione Revival by GTO Engineering, a British-built replica of an Italian icon with available air condition and USB port stereo. GTO Engineering's process takes other, older, front-engine Ferraris from the same era and then transforms them into something t...

Air quality unlikely to improve amid Western wildfires: scientists

PORTLAND, Ore. — Relief from putrid, dangerous air spewing from massive wildfires across the West won’t come until later in the week or beyond, scientists and forecasters say, and the hazy and gunk-filled skies might stick around for even longer. People in Oregon, Washington and parts of California were struggling under acrid yellowish-green smog — the worst, most unhealthy air on the planet according to some measurements. It seeped into homes and businesses, sneaked into cars through air conditioning vents and caused the closure of iconic locations such as Powell’s Books and the Oregon Zoo in Portland, the state’s biggest city. “I don’t think that we should be outside, but at the same time, we’ve been cooped up in the house already for months so it’s kind of hard to dictate what’s ...

How data centers can give back to society

The COVID-19 pandemic has accelerated the already powerful trend of digitization. Since the beginning of 2020, an increasing array of activities have been driven online: work (virtual meetings), shopping (online groceries), and entertainment (streaming). These trends add up to more demand for the workhorses of the digital economy — especially data centers, the buildings that house computer, telecommunications, and storage systems. The global data center industry is expected to grow by US$284.44 billion between 2019 and 2023, representing a 17 percent compound annual growth rate (CAGR), according to a report by Technavio. PwC’s Global Entertainment & Media Outlook 2020–2024 projects data consumed will grow by 2,342 trillion megabytes, representing a 20.9 percent CAGR. As the sector...

L.A.’s 2006 Heat Wave Was a Climate Change Warning

On July 16, 2006, a sticky, searing air mass parked itself over Southern California and stayed there for almost two weeks, creating one of the worst heat waves in Los Angeles’s history. For ten days, most parts of L.A. were dangerously hot, including record-high overnight lows, making it physiologically impossible to cool down without a window AC unit trained with laser precision onto your bed. On the evening that Woodland Hills, the hottest pocket of the city, hit 119 degrees, shattering L.A. County’s all-time-high temperature record, I gave up and slept on the floor of my Hollywood apartment, a frozen washcloth molded to my forehead. Last Sunday, that record was broken when the same weather station in Woodland Hills clocked in at 121 degrees. The changed climate was not, as predicted...

California heat wave could set all-time records, worsen wildfires

The heat wave is forecast to be even more intense than an extreme event in mid-August that played a key role in contributing to the massive blazes that have burned 1.5 million acres so far — raising a new term, the “gigafire” — concentrated around the San Francisco Bay area.Studies show that human-caused climate change is tilting the odds in favor of more frequent, severe and longer lasting heat waves, as well as larger wildfires throughout large parts of the West. New research published last month, for example, shows climate change is tied to more frequent occurrences of extreme-fire-risk days in parts of California during the fall (meteorologists define the fall as beginning on Sept. 1).The National Weather Service is not pulling any punches when it comes to the magnitude and health thre...

Elon Musk says Tesla will ‘one day’ produce ‘super efficient home HVAC’ with HEPA filtering

Elon Musk has previously touted the "Bioweapon Defense Mode" boasted by Tesla's vehicles, which are designed to provide excellent air quality inside the car even in the face of disastrous conditions without, thanks in part to high-efficiency HEPA air filtration. Now, Musk has said on Twitter that he hopes to one day provide similar air filtration along with home HVAC systems.Tesla, while primarily an automaker, is also already in the business of home energy and power generation, thanks to its acquisition of SolarCity, its current production of solar roofing products and its business building Tesla batteries for storage of power generated from green sources at home. While it hasn't yet seemed to make any moves to enter into any other parts of home building or infrastructure, HVAC systems...

(NASA) – In an interplanetary faux pas, it appears some pieces of asteroid Vesta ended up on asteroid Bennu, according to observations from NASA’s OSIRIS-REx spacecraft. The new result sheds light on the intricate orbital dance of asteroids and on the violent origin of Bennu, which is a “rubble pile” asteroid that coalesced from the fragments of a massive collision. “We found six boulders ranging in size from 5 to 14 feet (about 1.5 to 4.3 meters)...

Why the US-China chip war is heating up

© Provided by The Edge THIS past week, a new space plane prototype flew on a test flight from Jiuquan Satellite Center in the Gobi Desert, landing back on Earth on Sept 6. US satellites caught the landing and part of its journey. Beijing confirmed that a Long March 2F rocket had carried a “reusable experimental spacecraft” into orbit, describing the flight as an “important breakthrough”. The plane was modelled after US X-37B, an American space plane that has been operating for nearly a decade. A space plane such as US X-37B uses a lot of sophisticated equipment powered by state-of-the-art semiconductors. While China presented the experimental plane as a huge breakthrough, the truth is that it remains dependent on foreign semiconductor equipment manufacturers such as Applied Mate...

Forest fires in India

Fire is a good servant but a bad master, as the saying goes. The same is true for forest fires. Controlled forest fires have been essential for forest growth, but uncontrolled forest fire can engulf and destroy healthy, thick forest cover in no time. Various anthropogenic factors combine to cause uncontrolled fires. Fires of varying intensity and extent can affect thousands of hectares of forest every year, seriously influencing factor on nutrient cycling and functioning of ecosystem. Some forest ecosystems have evolved in response to frequent fires from natural causes, but most are susceptible to the damaging effects of wildfire. Each year millions of hectares of the world's forests are lost by fire, resulting in economic losses, environmental damage, and the loss of human life as wel...

Weakening duct supports a possible cause, say experts, Singapore News & Top Stories

The dislodging of a ventilation duct from the ceiling of a cinema hall at Nex shopping mall on Sunday was possibly a result of weakening duct supports, such as loose nuts and bolts or spalling concrete slabs, said industrial experts here. These ducts carry cool air from a central air-conditioning system to different parts of a building. Associate Professor Daniel Wong from the department of building at the National University of Singapore's School of Design and Environment said that the duct is usually bolted to metal rods that are secured to a concrete ceiling slab. "For the ventilation duct to fall, there are three main possibilities: a damaged rod, nuts and bolts which are loose or faulty, or that the concrete slab is beginning to rust or break," explained Prof Wong. "However, based ...

With global heating, expect inferno seasons in the American West

A firefighter battles the Creek Fire in Madera County, Calif., which has burned more than 175,000 acres. (Noah Berger / Associated Press)More than 3.1 million acres have burned in California this year — some 3% of the state — with many wildfires still at zero containment and months of fire season left to go. This far exceeds the previous record set in 2018, when 1.7 million acres burned, including the town of Paradise.These raging fires, some exacerbated by the blistering heat last weekend, are the direct result of climate change. The planet is currently 1.0°C to 1.2°C (about 2°F) hotter than it ought to be. This excess heat is entirely due to humans, mainly from burning fossil fuels and destroying forests. These activities release carbon dioxide into the atmosphere, which blocks some of t...

Why is everyone talking about ‘net zero’?

Countries, cities and businesses are aiming for 'net zero' emissions - but what does that mean and why does it matter? A U.N-backed global campaign to slash climate-changing emissions has added new high-profile members to its ranks, including social media giant Facebook and Ford, the first U.S. car company to join. The "Race to Zero", launched in June, brings together businesses, cities and other organisations that aim by around mid-century to cut their planet-heating emissions to net zero - meaning they produce no more emissions than they can offset through measures such as planting trees. As New York's annual Climate Week started on Monday, the British government - host of the next U.N. climate summ...
