Minding a Big Gap: Digital Divide Leaving Students Behind by Al Hammond

June 29, 2020 by Al Hammond

The Covid-19 pandemic has made profound changes in how we live. Many adults have had to adjust to working from home. But for school-age children, the change in their lives since schools closed this spring has been even greater. How are they coping with learning from home? The experience of two Eastern Shore counties—Talbot and Kent—suggests that distance learning can work, but that it doesn’t work for some children or even some teachers. The problems include:

The digital divide. Talbot and Kent are fortunate, because in both counties every schoolchild had already been issued a digital device (tablet, chromebook, macbook, depending on age). In both counties the majority of families with school-age children also have internet access at home—even if kids sometimes have to share it with parents working from home.

Interview with Kelly Griffith, Superintendent Talbot County Public Schools

But some children—as many as 15 percent—have no access at home, either because they live in remote locations or because their families can’t afford it. (In both counties, about 50 percent of the students qualify for free or reduced-price lunch.) Others have some access, maybe over a mobile phone, but not enough to stream a live session with a teacher or even to download a big homework file. So for these children, access means traveling to a WiFi hotspot, assuming that the family has a car and a parent at home who can drive them there and wait while the student goes online. Both counties have scrambled to provide more hotspots, working with county IT departments and commercial service providers; and both counties now have WiFi on their school buses, so that they serve as a kind of mobile hotspot. Talbot has also been mailing weekly packets of schoolwork to students who can’t get them any other way.

It’s not just students who lack access—so do some teachers is both counties. It’s a measure of their dedication that those teachers have been driving to school to deliver lessons from an empty classroom or even, in some cases, teaching from their car while parked at a WiFi hotspot.

Teachers are essential. As Bill Poore, Kent County Public School’s IT director says, “Zoom doesn’t replace a teacher’s hands-on help” with reading, or a stubborn arithmetic problem. And while some parents feel comfortable providing that kind of help at home, others do not—especially if it’s been a long time since they confronted an algebra problem or are simply not familiar with the devices and software tools that enable distance learning.

The schools are attempting to help: Kent County has adopted an on-line learning management system that simplifies things for kids or parents, and they have bought all-new devices for every student for the coming year. Talbot focused this past spring on basic topics that could be most easily grasped by a student or a parent without a teacher’s real-time presence (so-called “asynchronous learning”) and is working to have students catchup and finish any incompletes with week-long “boot camps” over the summer. But as Talbot County Public School’s Superintendent Kelly Griffith explains, “synchronous learning is important, because it increases student involvement.”

No one knows yet whether schools will be able to reopen in September, and even if they do, whether parents will feel comfortable sending their children while the pandemic is still active. So Griffith’s goal is to get everyone connected—to close the digital divide, one way or another—and she is seeking state permission for virtual programming. That might mean scheduled sessions with both teacher and students online together: English composition at 9, arithmetic at 10, science at 11.

Making rural broadband—and more effective learning—a policy priority. Last week, governor Larry Hogan announced a $45 million program to address the education digital divide. It includes a plan to build out wireless educational networks in western and southern parts of the state and on the Eastern Shore, using wireless frequencies reserved for educational use or other available frequencies. Hogan’s plan also includes money for devices and software tools, and for innovation grants to help public schools test new online educational strategies. It’s not likely that these new networks will be in place in time to help the coming school year, but it’s nonetheless a worthwhile effort that will eventually help to close the digital divide in rural Maryland.

The broader challenge, however, is to rethink education strategies. No matter how good the technology is, teachers will still need to play a central role. But why not design the educational process so that it happens seamlessly at school and at home? Why not use virtual reality tools (including virtual field trips) and hands-on interactive tools (such as 3D printers) to enhance student engagement—techniques now being rapidly adopted for industrial training? Why not use artificial intelligence tools to monitor student learning in real time and adjust the process individually to how each student learns best? It’s pertinent that in international comparisons, U.S. school children rank behind those of 12 other countries in reading and no better than 30th place in mathematics—and those dismal rankings haven’t changed in recent decades. Moreover the labor market is changing much faster than school curriculums—we’re going to need more software engineers and data managers and fewer truck drivers or assembly line workers.

Maybe the disruption of the schools by the pandemic—and the renewed attention to enabling every student to learn—will turn out to be the catalyst we need to reinvent education too.

The Transportation Revolution by Al Hammond

June 8, 2020 by Al Hammond

If you are thinking of buying a new car or light truck anytime soon, you may want to reconsider. That’s because conventional gasoline-powered vehicles are about to become technologically obsolete and economically uncompetitive—which means it will become progressively harder to find gas stations to refuel them, mechanics to repair them, or buyers for used vehicles when you want to sell.

One cause of this transformation is the impending surge in the production of electric cars and trucks by every major manufacturer. These electric models—apart from the cost of the batteries that power them—are already cheaper to produce (many fewer parts) and maintain than those with internal combustion engines. The batteries themselves are about to see dramatic improvements that will increase their driving range on a single charge to 600 miles or more, reduce the time required to recharge them, increase their lifetime, and lower their cost—which in turn will make electric vehicles less expensive to buy and far less expensive to operate than comparable gasoline-powered models. Indeed, Tony Seba, a Stanford University economist, has published estimates that electric vehicles will soon be 90% cheaper to operate than gas-powered cars, taking into account the cost of fuel and repairs over the lifetime of the vehicle. All these changes add up to one thing: gas-powered vehicles may no longer make economic sense.

A second major technology-driven shift is the coming scale-up of autonomous or “self-driving” vehicles that use multiple sensors to detect roads, traffic signals, driving conditions, and other vehicles, combined with artificial intelligence tools to interpret this data instantaneously and guide the vehicle accordingly. That will save lives: human drivers make mistakes that cause nearly 40,000 fatalities and 4 million injuries per year in the U.S. alone. The proliferation of self-driving vehicles will also mean that people can potentially use their travel time to do other things.

More importantly, many people won’t need or want to buy a car at all—they will summon a self-driving vehicle to take them where they want to go. This revolution—often called Transportation-as-a-Service (TaaS)—will happen in urban areas first, reducing traffic congestion and air pollution. Already Waymo (owned by Google) has driven autonomous vehicles over 20 million miles without any accidents and has completed 100,000 self-driving rides in its test city, Phoenix, Arizona; it is buying another 60,000 self-driving vehicles to use there, which may enable it to provide half of all the local travel needs for that city. Waymo is not alone: a company called Aptiv has also completed 100,000 self-driving rides in Las Vegas and is starting service in several other U.S. cities.

For those of us that live in small towns or rural areas and can’t imagine not having a vehicle in the driveway or carport, the TaaS transformation may seem irrelevant, but we will nonetheless be affected by it. Among other changes, TaaS combined with electric vehicles will disrupt the car insurance business, lower the revenue that governments get from gasoline taxes, save families that can avoid buying a car lots of money, and lower the cost of shipping goods (because of self-driving trucks). TaaS will change the value of homes and other real estate (imagine what can be built on all those soon-to-be-empty parking lots, which in cities like Los Angeles take up nearly one-third of the space, or how much less attractive a house outside the range of a TaaS service might be to a potential buyer). It will also enable expanded home delivery services for packages or food by self-driving electric vehicles or battery-powered drones.

If all this seems too abstract, consider the following: Consumer Reports estimates it costs about $15,000 to fill up a Jeep Liberty over five years, if you drive 12,000 miles per year; the electricity to power an electric Jeep Liberty is estimated to cost less than $1,600 over the same period. And fuel savings are just the beginning. The drivetrain in a conventional car has as many as 2,000 moving parts, compared to as few as 20 in an electric car. Electric vehicles have motors, not engines, so they don’t need to shift gears… and they don’t need oil, spark plugs, air filters, coolant, or transmission fluid. A conventional car’s engine might last 150,000 miles before it needs rebuilding, but electric car motors can last 600,000 miles or more. That’s why some electric car makers warranty the drive unit for up to 8 years, with unlimited miles—something no gas-powered car can offer.

So if you could buy essentially the same car, except cheaper and 90 percent less costly to use and maintain, quieter to drive, capable of much more rapid acceleration and greater pulling power, as well as likely to last several times as long, which would you buy? That’s why many experts think that electric vehicles will account for more than half of all new cars and trucks sold in the U.S. within 5 years. And because of TaaS, the total number of cars sold is likely to be far lower—and most cities are likely to have fleets of electric, self-driving cars that can each deliver 100,000 miles of rides a year with little maintenance.

While all that’s good for us as transportation users, it means disruptive change for quite a few segments of the economy. Professional drivers—chauffeurs, cab drivers, truckers—may simply disappear. Demand for mechanics and replacement auto parts will drop. Insurance companies will have fewer accidents to pay for and will have to lower premiums, losing revenue. We won’t need as many gas stations and truck stops—electric cars will mostly recharge overnight at home and self-driving trucks don’t need to stop for food and rest. Oil companies will suffer. With less traffic on the roads, driving (or being driven by your car) may replace short-haul air traffic and the hassles of airports, to the detriment of the airline industry. On longer trips, you could simply sleep in your car’s fully reclining seats while it drives you, so roadside hotels and motels may face problems as well. And as TaaS scales up, the sales of auto manufacturers will drop; many may not survive.

That’s what disruptive technological change looks like. It happened before when cars replaced horses; now it’s happening again as electric vehicles with self-driving capabilities replace conventional cars and trucks.

Saving the Choptank…and the Bay? By Al Hammond

May 18, 2020 by Al Hammond

It’s no secret that the health of the Chesapeake Bay ecosystem and its valuable blue crab and striped bass fisheries have been under threat from the region’s growing population and expanding economic activity. But a recent ShoreRivers report on improving water quality in some parts of the Eastern Shore of Maryland seems to suggest a positive trend. This is a story about actions leading to that trend, in which a U.S. National Oceanic and Atmospheric Administration (NOAA) laboratory located in Oxford, Maryland, has played a key role.

Agricultural land use dominates some parts of the Choptank watershed and is a major source of sediment and fertilizer runoff that contributes to poor water quality which may harm economically important fisheries. Source: NOAA

The seriousness of the environmental threat to the Bay’s fisheries was confirmed by a 2015 NOAA scientific study and a number of earlier studies that documented impaired water quality and poor biological health. A primary cause of the degradation, the studies found, was transformation of the natural landscape by agricultural activity and urbanization in ways that increased runoff into streams and rivers: runoff of sediment, nutrients such as fertilizers, and chemical and bacterial pollutants. The result is murky water, reduced underwater vegetation, and declining numbers of fish, crabs, and oysters coupled with increased levels of bacteria, fish disease, and fish parasites. The pattern of degradation seemed to track the types of predominant local land use, whether urban, agricultural, or forest.

Since 1983, the Chesapeake Bay Program has been working to improve the Bay. The latest agreement, signed in 2014 by six states, the District of Columbia and the EPA on behalf of seven federal agencies, committed to achieving a long list of measurable outcomes and improvements. Included in these are water quality targets to reduce sediment and nutrient runoff and to restore native oyster habitat and populations in 10 tributaries, 5 in Maryland and 5 in Virginia, by 2025. (Oysters filter and thus help clean the water).

Also in 2014, NOAA designated the Choptank River—the longest and largest river that empties into the bay and a key blue crab producer—a habitat focus area. As part of the overall Choptank effort, NOAA initiated a detailed scientific assessment of one of the river’s tributaries—the Tred Avon River that flows from Easton to where it empties into the larger Choptank near Oxford.

The study—conducted by NOAA’s Cooperative Oxford Laboratory—was a massive effort. Dr. Shawn McLaughlin, who directed the research, says it involved repeated sampling and data collection: “For three years we conducted daily, weekly, or monthly field trips to river sites in eight Tred Avon sub-watersheds spanning forested areas, agricultural lands, and urban areas.” The scientists measured water clarity and dissolved oxygen levels, concentrations of nitrogen and other nutrients, the presence of underwater vegetation, and numbers and types of fish and their health—including seasonal patterns. The resulting 2018 report documents the impacts of different land use patterns on water quality and fisheries health and suggests management practices that could help mitigate damage and restore ecological condition. The findings include:

Urban areas such as Easton, with their abundance of paved surfaces, are a major source of runoff, leading to higher levels of chemical contaminants, nutrients, and fecal bacteria as well as low dissolved oxygen levels in nearby bottom waters and the absence of many fish species during high summer temperatures.
Agricultural areas also showed high levels of nutrients and poor water clarity (which affects underwater vegetation that provides shelter and food for fish).
Watersheds dominated by forests had relatively good water quality and abundant fish and shellfish species.

The report pointed out the need for continuing efforts to reduce nutrient and sediment runoff across the entire ecosystem and the importance of preserving critical habitats for fish and shellfish, especially in spawning areas such as the Choptank. It also calls for innovative management approaches such as planting or restoring oyster beds and setting thresholds for land development.

Concurrent with the research, as part of the overall Choptank effort, NOAA’s Chesapeake Bay Office initiated an effort to coordinate local organizations with similar goals to achieve more than would be feasible if they acted alone. While this “collective impact” strategy had proven itself at community-scale, attempting it on a much larger scale was a novel approach for NOAA. An experienced environmental consultant was hired to stimulate and coordinate local action by working with local governments, non-profit organizations, philanthropic donors, and other stakeholders such as ShoreRivers.

The consultant, Joanna Ogburn, brought many groups together and created Envision The Choptank (envisionthechoptank.org), a partnership focused on pairing the scientific findings with local knowledge and local actors to find collaborative solutions. It used preliminary data from the NOAA Tred Avon study along with other Chesapeake Bay Program studies and data to guide pilot projects, get people excited about what was happening, and promote best practices among county officials, farmers and individual homeowners. The organization also hired coordinators to work with landowners 1-to-1, raised funds to provide incentives, and linked landowners to technical assistance. The Envision partner organizations have helped to engage many different entities, share tools and information and ideas, and coordinate strategies and funding efforts.

The effort has paid off. It enabled McLaughlin and her research team to meet with local, state and federal officials to share the evidence connecting land use to the condition of the aquatic ecosystem. It brought the laboratory together with Easton officials, Talbot county government and public works representatives, and ShoreRivers to discuss ways to “green” the proposed Port Street development in Easton by minimizing additional impervious surfaces that would intensify runoff. Envision partners also identified two stream restoration projects within the urban area and provided the Town of Easton with a small grant to design the projects, which led to a larger state grant to fully fund the work.

In another example, Envision partners engaged residential landowners to reduce storm water drainage. Using locations in the lower Choptank that the Oxford data showed regularly had low water quality, they got the Nature Conservancy to do digital map studies to determine the lands draining to those locations, then invited all the relevant landowners to workshops. There they taught residential homeowners how to build rain gardens and other techniques that improve water quality and the attractiveness of their properties. Envision partners have used the same strategy to identify agricultural landowners that are significant sources of runoff, so that they can reach out to them.

More than 35 organizations are now involved with Envision the Choptank, which is now expanding its efforts across the entire Choptank ecosystem. It organized a $1 million grant from the National Fish and Wildlife Foundation to engage, incentivize, and work with farmers in creating buffers and other strategies to manage runoff. Joanna Ogburn comments that “This grant is helping us launch a new wave of interventions. We’ve been able to build financial incentive programs to overcome the challenges landowners and farmers face in implementing restoration practices. We’re hoping to engage landowners in the Choptank watershed in creating buffers, wetland restoration, and drainage ditch management practices, ultimately restoring 230 acres.” And, as the latest ShoreRivers report suggests, these actions—at state and county and local levels—are beginning to show results.

It’s clear that the research and the scientific data it produced were critical in persuading both public officials and individual farmers and homeowners to get involved and take action. But it’s also clear that communication efforts and coalition building to find and implement local solutions were equally important—and that the Cooperative Oxford Laboratory played a central role in both. Suzanne Skelley, director of the lab, noted “Using research results to inform decision-making, especially to improve ecosystem condition while enhancing community resilience, is a core mission of the Lab and of NOAA.” The winning formula for saving the Choptank, and perhaps the broader Chesapeake Bay ecosystem, seems to be: science + communication/engagement + local action.

Why COVID-19 is Far From Over for the Mid-Shore by Al Hammond

April 13, 2020 by Al Hammond

At the start of the second week of April, hospitalizations are peaking in New York, the largest epicenter of the pandemic in the U.S. Meanwhile, there are just 9 known cases of the virus in Kent County, 10 in Talbot, and 16 in each of Queen Anne and Caroline counties. President Trump is talking about “reopening” the U.S. economy and sending people back to work. But don’t be misled. Many more people will get seriously ill in the months to come, and even if the virus seems to retreat in the warm summer months, it is likely to resurge in the fall and winter.

We don’t really know how widespread the virus is, because many of those infected show no symptoms, even though they can infect others. The only careful survey took place in Iceland, which tested 5 percent of its population and found that about 50 percent of those infected showed no symptoms. Applied to the U.S., that would mean at least 800,000 people have been infected, half of whom don’t know it and are likely infecting those around them. Consider also that in the period from December through February, when the virus was actively spreading in China, more than 750,000 people entered the U.S. from that country. So it is likely that the virus is far more widespread than we know.

Just consider what it means if an infected person spreads it to 2 others—then the next day those 2 infect 4 others, and so on—the definition of exponential growth. The math works out such that a single case could grow to over 200 million infected Americans within a single month. It’s easy to see how big cities such as New York quickly became hot spots of infection.

But cases are rising rapidly now even in small towns and remote rural communities—where a quarter of all hospitals have fragile finances even before the pandemic and are largely unprepared clinically for a surge of cases requiring ventilators. Testing is not widespread in rural areas, meaning we don’t really know the extent of the threat. And the virus has hardly been eliminated even in urban areas past their peak. So “opening up” the economy and sending people back to work anytime soon will simply launch a second wave of infections.

To open up safely will require massive testing—so we know who had already had the virus and is therefore immune and can’t affect others, so can be allowed to work—or waiting until 50 or 60 percent of the population becomes immune, enabling what is called “herd immunity.” That means it’s hard for the virus to spread, because those who are immune can’t pass it on. But letting the virus run free could still take several seasons of the virus to build up a herd immunity, and in the meantime would kill many of those who are most vulnerable—those over 70 or who have underlying health problems.

The current wave of testing identifies who is ill with the virus. To find those who have already had it and recovered requires a different kind of test—a so-called antibody test that identifies a specific protein in a person’s blood created by their immune system to fight the virus. The test requires only a finger prick of blood, results are available within a few minutes, and mass manufacture of the tests has begun. Still, it will likely take months and a coordinated national strategy to test every person working or who wants to go back to work, so that even a partial reopening of the economy safely is possible. Development of an effective vaccine will very likely happen within a year—but that means after the likely fall-winter resurgence of the virus. Until then, social distancing, working from home, and continued closure of non-essential businesses are the only effective tools.

Meanwhile, there is some good news on the vaccine front. The University of Pittsburgh School of Medicine (UPMC) just announced a potential vaccine for COVID-19. The team of scientists there did extensive research on earlier pandemic viruses: MERS in 2014 and SARS back in 2003. Both of those were also coronaviruses similar in the molecular structure to COVID-19. Their new vaccine research was just published in The Lancet, a leading medical journal. What’s unique about this vaccine is the delivery mechanism, which uses a small patch the size of a fingertip—like a small bandage—that has 400 very tiny micro-needles that painlessly deliver the vaccine over time, teaching the body how to produce antibodies to fight COVID-19.

This ease of use will help speed up adoption tremendously if the vaccine makes it to market. But clinical trials to confirm that the vaccine does no harm, even to vulnerable patients, and then to show that it really does protect people against infection, will take many months. For now, staying at home is the only “vaccine” that we have.

Maryland 3.0: Growing Green with New Hi-Tech Start-Up on the Shore by Al Hammond

March 17, 2016 by Al Hammond

Consumers in Kent County have begun to see a new, locally grown type of lettuce in food stores and on their plates at local restaurants. Notable for its attractive appearance, good taste, and lack of spoilage, what’s really different is how it’s grown—by a hi-tech process known as hydroponics. That means it’s grown not in soil but in plastic trays through which water and nutrients flow, inside a climate-controlled, computer-monitored greenhouse. The lettuce is consequently pesticide-free. The process yields a new crop every 6 weeks, but with staggered start times for different trays, so that fresh product is harvested every day, even in winter.

This new crop comes from Red Acres Hydroponics, a start-up venture based in Worton, on the grounds of a family-owned farm that also produces grain, hay, and straw by traditional farming methods. But hydroponics is hardly traditional and indeed may be the future of farming.

For one thing, crops grown with hydroponics typically use only 1/20th as much water, about 1/4th as much land, and no pesticides, compared to traditional agriculture, and they don’t require big fossil-fueled tractors or harvesters: the process is very environmentally-friendly. For another, hydroponic crops often have higher nutritional content, because their nutrient intake (more than a dozen different minerals) and the levels of carbon dioxide (which is “oxygen” for plants) in the greenhouse are continuously monitored and adjusted for optimum plant growth by the computerized system. So hydroponic crops get a checkmark is the “good for your health” column as well. And for Kent County customers, the produce is extremely fresh—Red Acres Hydroponics ships to restaurants and food stores several times each week (daily when needed). They also sell direct to consumers at their facility at Red Acre Farm next to the Kent County High School.

So how did such a novel venture take root in Kent County? Therein lies a human story of coincidence and entrepreneurship straight out of Silicon Valley. The founding team consists of Bryan Williams, a hard-working farmer whose family has owned and run Red Acres Farm for over a century; Liza Goetz, who is an award-winning teacher of agriculture and science at Kent County High School (she was chosen as Kent County Teacher of the Year for 2015); and Billy Wessel, who also has extensive farming and business experience. Last winter, Bryan’s wife Tracey, who is the principal at Kent County High School and thus Liza’s boss, was looking for a way to put some large potted plants inside during the cold season, and asked Liza if she could store them in the school’s little teaching greenhouse. When Bryan delivered them for her (they were quite heavy), he bumped into a small demonstration hydroponic system that Liza had set up for teaching purposes, and he asked, what’s that? So, never hesitant to teach, Liza explained. Then a few weeks later Brian and Tracey attended a dinner and happened to be seated at a table with a man from the Farm Bureau. Just making conversation, Bryan asked, what’s new in farming these days? “Hydroponics,” the farm expert said, and went on to explain why it’s going to be big. So on the way home, Bryan asked Tracey for Liza’s phone number, called her, and started what became an intensive process of research and planning that soon engaged Billy as well, and Dr. Joseph Bauer, a professor of business development at Washington College (and not coincidentally Liza’s father), and lots of other advisors and friends (many of whom told the team flat out “You’re crazy to do this”). But the team eventually convinced themselves that starting a new venture might be risky, but it was not crazy—rather a real opportunity too good to pass up—and decided, “It’s a go.”

In typical Silicon Valley fashion, the launch happened (and is still happening) with the team working nights and weekends while retaining their day jobs—Bryan is still running his farm, Liza is teaching full-time at the high school, Billy is volunteering his time. Bryan obtained a loan, and the facility was built last summer, adjacent to an existing barn. It consists of a huge plastic tent stretched over a series of steel hoops and then filled with the growing trays, carefully sloped so that the water and nutrients flow from one end to the other. (See photos.) Hooked up to the tent is a nutrient feed tank, air circulation, and climate control equipment, a carbon dioxide generator, and a sophisticated computer brain. Production started in October, with the team giving away samples to prospective customers. But as the team found its feet and gained confidence in their ability to manage the hydroponic process—it looks simple but is an incredibly complex, data-driven operation—sales have ramped up rapidly. Five months on, their facility is nearing its full production capacity, and the team is already starting to talk about when, rather than if, they will build a second unit. Moreover, from a business perspective, the venture has already crossed a magic line that took Amazon and Google years to reach—it’s cashflow positive, although it’s still getting quite a bit of volunteer help—Liza’s daughter Lizzy, Bryan’s daughter Rachel and son B (for Bryan), who are often onsite starting new plants in the nursery or helping with harvesting, as well as Bryan’s mom and partner in the farm Miss Sis (who keeps the books and makes snacks for the volunteer team).

Red Acres Hydroponics production facility near Kent County High School in Worton. It looks bucolic and simple—just lettuce growing in trays. But to make it work requires minute-to-minute monitoring of nutrient concentrations in the feed water and regular adjustments in carbon dioxide levels.

So far, so good. But it’s a fair question to ask of any new venture: Is this a flash in the pan, or something that could be significant for Kent County’s economic future? The customer feedback is excellent. Some of their restaurant customers have dropped their earlier suppliers for lettuce, most of whom ship from Florida or Arizona, because they found they had to throw away too much-spoiled produce. Others have told the team they value not only the quality of Red Acre Hydroponics lettuce (and the spices they now grow too), but, even more, the ability to call up this local business and say, “Can you get me three dozen heads before tonight?” The team also finds that individual consumers, as well as getting fresh produce in winter, really like the idea of supporting a local business. They are brainstorming new categories of customers, beginning to think about broadening their geographic reach to other parts of the upper eastern shore, getting more systematic about marketing and distribution. They will be creating full- and part-time paid jobs as they hire permanent staff. Just how big the venture can grow is uncertain, but it seems likely to become a significant local business at the least.

More importantly, if such a hi-tech green business can thrive here, it might help Kent County’s reputation as a place to do business, as a source of branded produce very much aligned with the national trend toward local, healthy foods, or as an environmentally conscious community. Might more such businesses make the county an attractive place to live for health conscious families? Might the success of one hi-tech startup attract others—especially given the prospect of good internet connectivity across the county? Might an incubator for new businesses being discussed at Washington College—one that encouraged and helped other small startups take root and flourish here—begin to generate real momentum? It certainly can’t hurt. Stay tuned, and pass the salad dressing.
