CANARY IN THE COAL MINE FOR SCHOOLS: What’s going on here—a tech savvy dad strapped a CO2 monitor to his kid to check air CO2 exposure on a school trip. Crazy high CO2 indicates poor indoor ventilation.

Ventilation & air disinfection will prevent outbreaks. #COVID19 #Ventilate
2) VENTILATION is key. Both ventilation and masks needed to reduce risk indoors. But most buildings not ventilated well enough.

3) we need to disperse aerosols quickly. Key is ventilation. 🇯🇵 assumed it was airborne from the beginning. Here is how to ventilate your school classrooms if unable to open windows. #COVID19
4) If indoor dining isn’t okay, then why indoor school cafeterias safe? We need outdoor school lunches.

What sent Texas reeling is not an engineering problem, nor frozen wind turbines. It is a structure that offers no incentives to prepare for winter. In the name of deregulation and free markets— electric grid that puts cheap prices over reliable service. 🧵

2) It’s a “Wild West market design based only on short-run prices,” said a portfolio manager, Matt Breidert. The temporary train wreck has seen the wholesale price of electricity in Houston go from $22 a megawatt-hour to about $9,000, while 4 mil Texans have been without power.
3) “One utility company, Griddy, which sells power at wholesale rates to retail customers without locking in a price in advance, told its patrons Tuesday to find another provider before they get socked with tremendous bills.” washingtonpost.com/business/2021/…

TEXAS LEADERS FAILED—power outages raise fears that herds could run short of food and water. Some farmers are being forced to dump tankers of milk on fields because it can’t be processed, & livestock maybe euthanized if no water or food. #texaspoweroutage wsj.com/articles/texas… Image
2) “No feed, no water, and no heat doesn’t make for a good situation,” said Texas agriculture commissioner. Some areas had gone without power for >30 hours straight—while fielding calls from cattlemen losing calves to the cold & poultry farmers struggling with frozen water pipes.
3) Sanderson Farms Inc., one of the biggest U.S. chicken companies, estimated that as many as 200 of its approximately 1,900 Texas chicken houses were without power, & dozens have ruptured or frozen water pipes. Mills are struggling to make animal feed without access to power

A healthy boy before—18 weeks of agony for 13 year old boy suffering #COVID19.

“His heart—we didn't catch that for 2 months—now we're dealing with a coronary issue that we don't know if it will resolve.” 🧵

#LongCovid & kids is real. (HT @MaritsaNBCMT) nbcmontana.com/news/local/new…
2) “A lot of people really do not understand how dramatic the effects of COVID are on children,” Lisa Beard, Hudson’s mom, said. “A lot of times, we want to protect the most vulnerable, the small under 1 and the elderly, but Hudson was a thriving, very active 13-year-old.”
3) “It’s been nearly 18 weeks of agony for Hudson, who contracted #COVID19 in Nov. He hasn’t been to school since.
“It is hard. It’s really hard when doctors don’t have an answer, & they’re like, ‘Well, over time let’s see what happens. And you might get better, we don’t know.’”

“About 80% of [Texas] power grid is fueled by nuclear, coal and natural energy. Only about 7% are wind turbines and renewables. And those too, yes, have frozen but they can be winterized to be ready for this type of weather." ~Texas Tribune @viaAlana.
2) Indeed, most of the ~20 GW deficit doesn’t come from wind. Wind output is only 2.6 GW below normal. Image
3) this crisis isn’t over for millions.

💡CHALLENGE STUDY OF LIVE CORONAVIRUS—world’s first #COVID19 human challenge study within a month.
Up to 90 carefully selected, healthy adult volunteers aged between 18 and 30 to be exposed to #SARSCoV2 in a safe and controlled environment. Important! 🧵

2) The initial trial aims to establish the smallest amount of virus needed to cause infection, probe the body’s immune response, and explore how the virus is passed on from person to person.
3) Participants will be closely monitored by medics and scientists 24 hours a day following their exposure to the virus. The team add that the virus used will be the variant that was circulating in the UK last year rather than those that have recently emerged.
