World's Largest Floating Solar Farm to Provide 10 Million People With Clean Drinking Water
England will soon be home to Europe's largest floating solar farm, if not the world. The 6.3 megawatt array consists of 23,000 solar panels that sit on the Queen Elizabeth II reservoir at Walton-on-Thames, a suburb of London near Heathrow Airport.

According to The Guardian, the £6 million (about $8 million) project will help power local water treatment plants that provide clean drinking water to London and south-east England's 10 million residents
“This will be the biggest floating solar farm in the world for a time—others are under construction,” Angus Berry, energy manager for Thames Water, the utility which owns the site, told The Guardian. “We are leading the way, but we hope that others will follow, in the UK and abroad.”
Thames Water said in a press release that their floating pontoon will cover around a tenth of the Queen Elizabeth II reservoir, the same area as eight Wembley football pitches (London's famous 90,000-capacity soccer stadium).
It will be the largest floating solar farm on the planet before Japan's mega-solar farm finishes in 2018, which will have a capacity of 13.7 megawatts.
Thames Water, which has goal of generating a third of of its own renewable energy by 2020, said that the low carbon, renewable energy produced at the facility is expected to generate 5.8 million kilowatt hours in its first year—equivalent to the annual power consumption of around 1,800 homes.
Floating solar panels has a number of benefits. For one, compared to mounted panels, floating panels are naturally cooled because of the bodies of water they sit on, therefore boosting power production efficiency. The panels also shade the water itself, and limits the growth of algae.
Berry also told The Guardian that the project makes use of a space that is not currently used for any other purpose, adding that the array will have no impact on the ecosystem.
Also, as as Quartz noted, a floating platoon is easy to assemble: "Rather than using heavy machinery required for ground-mounted installations, the panels are clipped together and pushed out from the bank of the lake."
For instance, this 200 kilowatt floating solar power farm in Sheeplands Farm, Berkshire was constructed in one week:
European solar photovoltaic operator Lightsource is managing the installation of London's new floating solar array.
“We’re delighted to have begun work on another ambitious milestone project for Lightsource with our first floating solar installation," said Lightsource CEO Nick Boyle in a statement. "Over the last five years we’ve successfully completed ground and roof installations of all shapes and sizes, but this project has some obvious differences and has presented our team with a set of fresh challenges to overcome.
“There is a great need from energy intensive industries to reduce their carbon footprint, as well as the amount they are spending on electricity and solar can be the perfect solution. We’re therefore constantly evolving new skill sets to ensure that all of our projects deliver maximum energy generation over the lifetime of the installation.”

It's going to be back-to-school time soon, but will children go into the classrooms?
The American Academy of Pediatrics (AAP) thinks so, but only as long as safety measures are in place.
Keeping Schools Safe<p>What will safer schools look like?</p><p>In a <a href="https://jamanetwork.com/journals/jama/fullarticle/2766822" target="_blank">JAMA article</a> published last month, <a href="https://www.jhsph.edu/faculty/directory/profile/1781/joshua-m-sharfstein" target="_blank">Dr. Joshua Sharfstein</a>, a pediatrician and professor at the Johns Hopkins Bloomberg School of Public Health, outlined suggestions — many of which are similar to AAP's.</p><p>Remote learning protocols must stay in place, especially as some schools stagger home and in-building learning. If another shutdown needs to occur, children will rely on distance learning completely, so it must be easy to switch to, he said.</p><p>He suggested giving parents a daily checklist to document their child's health. Kids should be screened quickly on arrival and be given hygiene supplies. Maintenance staff should use appropriate PPE and have regular cleaning schedules. A notification system should be in place if a case is identified, Sharfstein recommended.</p><p><a href="https://www.albany.edu/rockefeller/faculty/erika-martin" target="_blank">Erika Martin</a>, PhD, an associate professor of public administration and policy at University at Albany, said nutrition assistance and health services should be included. She called for tutoring programs with virtual options as well as technology access.</p>
Supporting Staff<p>Teachers and staff will be affected by safeguarding measures, noted <a href="https://directory.sph.umn.edu/bio/sph-a-z/rachel-widome" target="_blank">Rachel Widome</a>, PhD, an associate professor of epidemiology and community health at University of Minnesota.</p><p>"In order for all of the in-school precautions to work well, we'll be asking a lot of teachers and staff," Widome told Healthline. In addition to their usual workload, they'll now be asked to monitor mask-wearing, ensure children are keeping distance, and be aware of any symptoms.</p><p>Along with Sharfstein, Widome called for an increase in financial support. More employees will likely be required so teachers and staff members can keep up with the added demands.</p>
Should Kids Go Back?<p>While these guidelines may help get some schools to reopen, many people don't think children should go back to school over fears they could contract the disease and spread it to other vulnerable family members like grandparents, infant siblings, or their parents.</p><p>In a <a href="https://pediatrics.aappublications.org/content/early/2020/07/08/peds.2020-004879" target="_blank">Pediatrics</a> commentary, <a href="https://www.md.com/doctor/william-raszka-md" target="_blank">Dr. William V. Raszka, Jr.</a>, an infectious disease specialist at The University of Vermont Medical Center, argued that schools should open because school-aged children are far less important drivers of COVID-19 than adults.</p><p>But he says the risk and benefit is not equal among all students ages 5 to 18.</p><p>"Elementary schools are arguably higher priority for face-to-face schooling, since younger children are at lower risk for infection and transmission, and since parental supervision of younger children's distance learning may be particularly challenging," added Sorensen, who penned a <a href="https://jamanetwork.com/channels/health-forum/fullarticle/2767411" target="_blank">June article in JAMA</a> with reopening tips. "That means middle and high schools are more likely to emphasize distance learning."</p><p>Specific student populations, such as special education students and students with disabilities, would also benefit greatly from more time spent in face-to-face environments, Sorensen said.</p>
What Parents Can Do<p>Parents should ask for and receive frequent updates from schools about plans for the fall. They should also be informed about plans if and when COVID infections are identified, Sharfstein said.</p><p>"I'd like to see parents investing now, during the summer, in doing things that can slow and stop the spread of the virus in their communities," Widome said.</p><p>"Now is a good time for kids to practice wearing masks and get used to them as they may be wearing them for longer stretches if school starts up in person," Widome suggested.</p><p>She recommends parents try different mask designs and materials to see what children are more comfortable wearing.</p><p>"If you are using cloth face coverings, it's good to have extras on hand," Widome added.</p><p>Parents should model healthy behavior at home and while out in public — another thing that could affect how well children adapt to reopening practices, Sorensen said.</p><p>"Children may want to know more about face coverings," added <a href="https://www.linkedin.com/in/leescott/" target="_blank">Lee Scott</a>, chairwoman of the Educational Advisory Board at <a href="https://www.goddardschool.com/" target="_blank">The Goddard School</a>. "Dramatic play, such as creating or wearing a face covering, may help some children adjust to this concept." Schools can also show children photos of what faculty members look like in their masks so the students are familiar with that appearance.</p><p>Johns Hopkins University recently released its eSchool+ Initiative, a slew of resources surrounding education during the pandemic. These include a <a href="https://equityschoolplus.jhu.edu/reopening-checklist/" target="_blank">checklist for administrators</a>, report on <a href="https://equityschoolplus.jhu.edu/ethics-of-reopening/" target="_blank">ethical considerations</a>, and a tracker of <a href="https://equityschoolplus.jhu.edu/reopening-policy-tracker/" target="_blank">state and local reopening plans</a>.</p>
