Opening windows and doors to let in fresh air is as important as wearing masks and social distancing to prevent coronavirus. In places where people gather and in homes it is important to let in fresh air so that there is new fresh air circulating in rooms 3-4 times for every hour. It is being used as a strategy in schools in Germany to bring in fresh air. Putting MERV 13 type air filters in central air conditioning and heating systems is important in offices, shops and other spaces. A complete redesign of the systems that are old is needed. There are 36,000 schools in the U.S. that have old failing systems of heating and cooling. It would cost $360 billion to change these systems if each system cost $10,000 which is on the low side. This shows that good intentions are not enough, new priorities need to be set and the old priorities which misallocated funds through existing capital allocation structures in the West coasts and East coast cities no longer serve the purpose of the Renewal of America.  ...

The problem of breakthrough infections requires people to follow all necessary prevention measures including social distancing, mask use, ventilation of indoor spaces, and hand washing, even if they are fully vaccinated. People who have taken vaccination very early in 2021 and have waning protection need a booster shot to build up immunity levels. Studies show that breakthrough infections can take place, making it all the more important to take all precautions.

Colleges and universities are preparing to reopen and investing in the changes required for coronavirus prevention and control. Installing plexiglass, hand sanitizer stations, and ensuring availability of face masks on campus, arranging for labor to do the hourly wipedown of door knobs and for taking student temperatures, are steps colleges are taking to reopen. Some universities expect to reopen with 30% of classes in face to face settings.

Other planning includes installing upgraded ventilation systems, retrofit doors for motion sensor technology or foot operated openers. Also included infrared technology to detect temperatures and ultraviolet lighting disinfection technologies.

Apoorva Mandavilli of the NYT looks at the huge task of renovating the aging infrastructure of America's schools, like this one East High in Denver. The average school building in America is over 50 years old. Having clean air in the schools would have reduced the incidence of Covid by 50%, say studies. The General Accountability Office GAO says 41% of school districts in the US have at least half of their buildings, a total of 36,000 buildings, that need to completely replace their heating cooling and air ventilation systems. The money is there, secured by president Biden with $200 billion from programs like the American Rescue Plan, but much of it remains unspent because of a lack of clear administration guidance on clean air and an official to oversee this effort, and expert guidance, securing equipment in the supply chain.

In the first 6 months of 2020 about 21 million jobs were lost in the U.S., followed by a recovery following reopening with a third of the jobs regained by July 2020. Women and black people were disproportionately hit by job loss during the pandemic. Hispanics were hit the hardest but also recovered faster.

As the lockdowns dragged on in June, mental health, vaccinations  getting treatment for health conditions, and economic well being, became major objectives. This was accomplished through better incorporation of better practice such as social distancing and face coverings, ventilation, and healthy living practices including food, as more people went back to work. Bars and large gatherings remained a particularly vexing problem, with sports now being played in empty stadiums for television audiences. Offices were completely redesigned to be safe places for work and public transport featured empty seats.

The failure to set clear and consistent guidelines by the U.S. Centres for Disease Control that the public can easily grasp and follow without retractions or errors has affected how the public responded in the pandemic. Here the CDC is shown to have first put forward a draft version on the role of aerosol and respiratory droplets in the air for spreading coronavirus infections and then pulled it back followed by putting it back on last week.

Much of it is about being definitive and 100% certain instead of focussing on the steps that are clearly going to reduce the spread of the pandemic and appealing to the good common sense of the public about following reasonable precautions of social distancing, masks, ventilation, staying away from gatherings.

A growing consensus among experts that it is not so much surface contamination as the air we breathe in that is the problem. The longer you spend time with people talking in face to face interactions, or inhaling air aerosolized in the air from small droplets, the easier it is to get the virus. This means social distancing matters in a big way. Masks are a big way to cut the risk. The worst you can do then is to be in a crowded event, ot have closeup face to face interactions for long periods. Being where there is loud talking or singing is a bad idea. This is why actions such as plexiglass installed as barrier, requiring masks in stores, using good ventilations systems and keeping windows has an enormous impact. This means that people can do a lot of work, exercize and other activities outside if one takes the basic precautions to heart and practices seriously. Contact tracing and testing, and other measures can be targeted to keep the spots that have a surge under control. ...

Mayor Johnson on the city, its new buses, and how he got introduced to politics in the city of Wolverhampton, England. He prefers the hop-on, hop-off, classic London buses, that use British technology which he reintroduced. His point about how he got started in politics is an eye-opener- the time time as a reporter in Wolverhampton, when he got fed up with the stuff about the damp and mold and needing ventilation in people's homes, which Labor politicians made it appear that it was the state's responsibility, making people dependent just for the votes.

These are key provisions in the biggest climate change bill in history- Tax credits that last for over a decade for zero carbon plants- these tax credits go to companies that build new sources of emissions free electricity, for wind turbines, solar panels, battery storage, geo thermal plants. Tax credits also for new technologies that capture and bury carbon dioxide from natural gas plants and industrial facilities before it escapes into the atmosphere and heats the planet. This technology is rarely used because of high costs. Incentives for electric vehicles- It extends a tax credit of $7500 for new electric vehicles. It adds a $4000 tax credit for used electric vehicles. Tax credit goes only to people earning $150,000 a year (300,000 for joint filers) for new EV's and $75,000 (150,000 for joint filers) for used EV's. Help for people to lower energy costs - $9 billion in rebates for Americans installing energy efficient electrical appliances. And a decade of tax credits for Americans installing rooftop solar, heat pumps, water heaters and electric HVAC, or electric heating, air conditioning and ventilation technologies. Investments in Domestic Manufacturing- $60 billion for investments in clean energy manufacturing in the US. This includes $30 billion for production tax credits for solar panels, wind turbines, batteries and critical minerals processing. $10 billion in investment tax credits to build manufacturing facilities for electric cars and renewable energy technologies. This action is to halt the shifting of clean energy manufacturing overseas to China. $27 billion towards a green bank that would finance clean energy projects in disadvantaged communities. Cracking down on Methane- the bill places a fine on methane gas emissions from oil and gas wells and pipelines and other infrastructure. Fees of $900 per metric ton in 2024 and $1500 a metric ton in 2026 when it exceeds federally set limits.    ...

Schools, shops, restaurants, cafes and offices are reopening and people are getting back to work and outdoors. What are the ways to reduce chances of getting the coronavirus and what is the latest advice from public health experts.  More attention is now being given by CDC and other experts to the aerosols, the smaller particles that are airborne that can spread the virus to people unawares in breathing, talking and singing activities. larger droplets come down to the ground, smaller droplets can be airborne for hours. This makes masks wearing very important, call it essential protection. Air filtration and proper ventilation is also important. What about social distancing? Experts now say 6 feet is good, 10 feet is better. This is from Joseph Allen director of the Healthy Buildings program at Harvard School of Public Health. No magic number but 6-10 feet or more is good for safety. Can one start expanding one's social circle? The fewer contacts the better says Dr. Allen. You can he says expand the circle but this depends a lot on how serious the other family is in taking precautions. Are elevators risky? If one can one should take stairs but do not board a crowded elevator unless the lobby is more crowded. Do not touch buttons, if you do use elbow or use sanitizer from your shirt pocket after pressing. This is where mask is essential. Here a tip is useful. Talking does not help as talking emits 10 times the particles than when you are quiet and this is true for small spaces such as elevators. Continual talk is not a good idea such as a long time spent talking, here watch that habit of getting into long conversations face to face.  Is it good to take a summer vacation. Here the answer is yes, as no one really knows how the winter will be. And remember outdoors is good for renewal of health, and one can look for places that are not crowded where the 10-12 feet or more can be easily done. One tip here is to take your own food and supplies from home so there is no need to go to crowded restaurants. Swimming in a lake or ocean is fine. Camping outdoors is fine and actually a good idea if you are with your own family. Try to use an empty restroom and one that is clean and wear the mask. While camping keep the 6-10 foot rule with people outside your immediate family, do not share food and drinks and try not to touch each other's supplies, and sanitize your hands or wash if you do. When hiking keep the mask in your pocket so you can wear it when you see others passing on trails. In hotels skip the cleaning service, in a rented property ask the owner to keep the windows open before you arrive, and put a day or two between your coming and the last person who rented the place. Renting a car is tricky allow a couple of hours to elapse between you and the last rental, open windows. Public restrooms. Always wear a mask many are poorly ventilated. Open the door without use of hands if possible,or use a paper towel to open and discard. Do not use air dryers. Is it safe for your house cleaning person to return. Keep the windows open to let in fresh air. Make sure your cleaner wears gloves. And all should wear masks. How to visit grandparents? Experts advise keeping visits outside and wearing masks when not 6-10 feet apart. Anyone not feeling healthy should avoid the visit. And bathrooms should be sanitized after people leave even wait a day if there is another bathroom. Experts advise against sharing food and buffet type meals. Ten feet distance is better than six feet. Can one use a gym? Here the advice is to exercize outdoors or at home if one can. It says be cautious unless your gym is limiting the number of people or spacing the equipment adequately. Ask about open windows, air filtration systems, ventilation.  This is excellent advice from experts with the latest information. Over the last few months from March to May most of the information was during lockdown, and a lot can be forgotten or seen as not necessary as things return to normal, as shops schools and cafes, office reopen, and cases remain steady and under control. Being vigilant is good for safely navigating this period through the summer and into winter till a vaccine is found. It is also about being a good civic minded person aware of one's own responsibilities, as when all take safety seriously and practice it everyday, it builds another layer of protection for everybody- because it creates a safer environment for all.     ...

Dry air is not good for preventing spread of coronavirus droplet inhalation as the droplets stay in the air longer. Humidity should be between 40% and capped at 60% say two studies from Germany and India. Coronavirus aerosols are the problem and there is less chance of the people breathing in droplets if the air is not dry. Opening of windows helps. Dry air also makes mucous membranes in the the nose dry and more permeable to viruses. Too much airconditioning or too much heating should be avoided says this report and ventilation is good.

Toyota moves back to its utilitarian roots, where costs matter and pricing matters. Higher cost technological advances are being rejected in favor of older approaches that accomplish the same thing in the manufacturing process at alower cost. And pricier features like the solar ventilation system option on the new Prius are being rejected so that the price can be made more competitive with American cars. Even the idea of pricing Toyota's cars at apremium of $1000 or $1500 over American cars is being questioned in this market. The new Prius mad due to come out this year, developed at a time when Toyota was coasting as it emerged as the most profitable and the largest auto manufacturer in the world, has a price tag of $28,000 versus the $22,000 for the current Prius. This has alarmed some of the bigger Toyota dealers so much that Akio Toyoda the new CEO visited Southern California to talk to these dealers about what has gone wrong with the pricing. These dealers told him that they were worried about that price when they were drastically discounting current Prius models to maintain their sales rate. This is also happening when Toyotas are piling up unsold on car lots at most ports in the US. As Toyota competed with GM for top spot in sales Toyota's management of Watanabe and Kinoshita, the outgoing CEO and his assistant, say critics inside Toyota, lost sight of the need for caution as the company's manufacturing capacity expanded in Japan and overseas. Now with the selection of Akio Toyoda to succeed Watanabe as new CEO, the decision has been made to make a shift to anew generation of managers, with the retirement of 3 executives including Kinoshita and Watanabe. ...
